.UNDESCRIBEDCRANE.F'LIES FROM TROPICAL(DIPTERA,AMERICA
TIPULIDAE). PART I
By CuenLESP. ArexamDER,Amherst, Mass.

The novelties described herewith were received from various
correspondentswho are indicated under the various species. Except where stated to the contrary, the types are preserved in mypersonal collection of these flies.
Longurio (Tanypremna) fieldiana n. sp.
General coloration of head and body orange yellow; halteressnrall, the knobs weakly infuscated; wings with the ground faintly
yellow, the base and costal border broadly bright yellow, stigma
dark brown, conspicuous;basalsectionof vein M r*r more than twice
the secondsection.
Fernale: Length about 15 mm.; wing 11 mm.
Frontal prolongation of head light yellow, without nasus; palpi
light brown, outer two segmentsbroken. Antennae with scapeand
pedicel light yellow; flagellum broken. Head orange; anteriorvertex broad, nearly four times the diameter of the scape.
Pronotum orange. Mesonotum chiefly yellow, unpatterned or
virtually so. Pleura yellow. Halteres small, stem obscureyellow,
knob more infu.scated. Legs with the coxae and trochanters yellow; remainder of legs broken. Wings with a faint yellow ground,the prearcular and costal regions deeperyellow; stigma small, darkbrown; veins heavy and very conspicuous,dark yellow in the brightened portions, elsewheredark lrrown. Venation: Compared withauranti,othorar, Rs longer and more gently arcuated; r-rn a littlelonger; basal section of M r*o more than twice the second section.
Abdomen dull orange.
Hobitot: Panama (Canal Zone).
Holotype, a broken i, Camp Butler, January 20, L954 (GordonField).
I take great pleasurein naming this interesting speciesfor Captain Gordon Field, to whom we are indebted for great series of
insect specimensfrom Panama. The fly is allied to Longurio(Tanyprentna) aurontiothorar Alexander, of the Cerro Azul,
Amazonian Peru, agreeing in the general coloration of the body andwings, differing very evidently in the much heavier and conspicuous dark brown veins of the wing disk. Unfortunately, the malesex remains unknown.

Ozodicera (Ozodicera) carrerella n. sp.
Size large (wing of fernaleover 20 mm.); flagellarbranchesof
femalestout, nearly as long as the segments;mesonotalpraescutum
gralt with four darker brown stripes, pleura and pleurotergite
light silvery gra)'; fernora brown, llroadly brorvnish black basally,mbre narrowly so at tips, tarsi black; rvingsheavily patternedwith
brown and white, stigma light yellorv; vein M , sinuou.s,cell M t
broadly sessile; abdominal tergites gray brown medially above,blackenedon sides.
Fernale: Length about 24 ntm.; rving 21 r11m.;antenna about
4.5 mm.
Frontal prolongationof head light brorvn; nasusdistinct; palpi
black. Antennaewittr the scapeauclpedicellight brown, flagellum
brownish black, including the branches,the incisuresnarrowly yellowed; branchesa little shorter than the segmentsbut stouter.
Head brownish gray; anterior vertex reducedto a narrow line thatis only about onc-third the diameterof the scape.
Pronotum brownishgray, clearer gray on sides. Mesonotalpraescutum with tl-reground gray, clearer laterally, with fou.r darker
pair separatedby a capillaryobscurebrown stripes,the interrrrediateyellow line that widens and darkensbehind; posterior scleritesof
notum light gray,eachscutallobe with two confluentbrown areas;
centers of scutellum and mediotergiteweakly darkened. Pleuraand pleurotergitelight silvery gray ; dorsopleuralmembranedusky.
Halteres with the stem brown, the base and the knobs brownish
black. Legs r,r'ith the coxae gray; trochanters brown; femora
brown, more brownish black basally,lnore narrowly blackenedat
apex; tibiae reddish brown, the tips blackened; tarsi uniformly
black. Wings heavily and handsomelypatternedwith brown andwhite, the dark ground more intense on the anterior two-thirds,paler as broa<lmarginal darkeningsin the outer medial and anal
fields; the chief white areasincludemajor marks in cells R and M ;cell 1sf M, and,basesof outer radial cells; outer half of cell Rs andbroad basesof all outer nredial cells, most extensivein Ma, andbroad basesof the Anal and Cubital ce[s ; lessevidentbrightenings
at baseof cell R, and end of cell Rr; stigma conspicuouslybrightyellolv; prearcular region, except in anal portions dark brown;veins dark brown, lllore reddish brown in the whitened areas.
Venation: Vein M , sinuous,widening cell Ru at near two-thirds its
length; cell M , very broadly sessile.
Abdominal tergites rvith the sublateralparts heavily gray pruinose,the lateralborderswith a broad black stripe that is constricted3or narrowly interrupted at the cephalicpart of eachsegment;middorsalregion of tergitespaler brown, borderedby cinnamonbrown;sternitesinfuscated,the basalrings paler; genital shield blackened.
Habitat: Brazil (Rio de Janeiro).
Holotype, t, Mount Itatiaya, 900 meters,October 3, 1951 (M.
Carrera) ; type returned to Carrera.
This very attractive fly is named for Messias Canera, distinguishedstudent of NeotropicalDiptera. In its striking wing pattern, the fly is most like the much srnaller Ozodicera(Ozodicera)eliana Alexander, likewise from southeasternBrazil, differing in
the coloration of the body, structure of the antennae,and in all details of wing pattern and venation.
Tipula (Trichotipula)selanderi n. sp.

Size large (wing, male, 14 mm.) ; abdomenvery long; generalcolorationfulvous,the vertex and abdominaltergitespatternedwith
darker; trochantersblackened;wings deepfulvoqs, stigma scarcely
darker, veins dark yellow; male hypopygium with the posteriorborder of the tergite with a deep and narrow V-shapednotch, themarginswith unusuallyabundantlong black spinesthat are directed
mesad.
Male: Length about22mm.; wing 14 mm.; antennaabout3 mm.
Describedfronr an alcoholicspecimen.
Frorrtal prolongation of head about as long as the remainder,orange; nasus long and slender; palpi brownish yellow, the outer
segmentsdarker. Antennae with the scapelight brown, pedicel
arrd first flagellar segrnentobscureyellow; remainder of flagellum
black, the segmentsfeebly incised,verticils shorter than the segments. Head aboveinfuscated,the genaeand the high entire vertical tubercle more fulvous.
Pronotum yellow, narrowly darkened medially above. Mesonotal praescutumand scu,tumorange, the posterior scleritesand
pleura rnore yellowed; thorax glabrous. Halteres with stem pale,the knob a trifle darker. Legs with the coxaeyellow; trochantersbrownish black; remainderof legs broken except for a short fragment of a rniddle femur which is blackened,indicating the probability that the legs are uniformly black. Wings deep fulvous, theprearcular field, with cells C and Sc, more saturated,a little darker
than the stigma; veins dark yellow. Macrotrichia in outer ends ofcells Rr, Ru and M ,, most numerousin Rr. Venation: R, gently
basal section of.M aarcuated; cell t-st M n broader than in ztultteosa,'
very long, perpendicular.
Abdomen very long, yellow, the tergites with a conspicuous

4
medianbrown stripe that is constrictedat the incisuresbut is continuous; hypopygiumyellow. Male hypopygrumwith the posteriorborder of the ninth tergite with a very deepand narrow V-shaped
notch,the marginswith unusuallyabundantlong black spinesftrat
are directedmesad. Outer dististylenarrowedoutwardly; innerstyle with the beak slender,lower beak heavily blackened.
Habi,tat.'Mexico (Guanajuato).
Holotype, alcoholicJ, Irapuato, 5,000feet, August lgsz (R. K.
Selander).
I namethis distinct fly for the collector,Dr. Richard K. Selander,of the Illinois StateNatural History Survey,studentof the Meloidae. The most similar speciesis Tipula (Trichotipula) ztultuosa
Alexander,likewisefrom Mexico, which differs in all details ofcolorationof the body and appendages.
