UndescribedSpeciesof Crane'fliesfrom the Eastern
United Statesand Canada(Dipt. : Tipulidae).
Part IV.
By Cuenrns P. AmxeNoen, MassachusettsAgricultural Coll.gq, Amherst; Massachusetts.
In the present installment under this general title, four undescribed speciesof the genus Tipula from the Southeastern
Llnited States are discussed. As before, all of these species
were collected by -y friend, Professor J. Speed Rogers, tolvhom my sincerethanks are extended for the privilege of examining this important series. The types have been returned toProfessor Rogers.
Tipula osceola sp. n.
Belongsto the tricolor group; allied to T. sof Alexander and'antennaeof male relatively long, theAlexander ;T. Iudozti,ci,ana
flagellar segmentsvery strongly constricted so as to appeaf binodose.
3. Length about 14 mm.; wing 12.5 mm.; antenna about 5mm. ?. Length about 2O mm.; wing 17-18mm.
Frontal p.olongation of head light gray above,darker 1u!"1ally, the ttitu. slincler; palpi brownish black. Antennae (d)relatively elongate, conspicuous,the segments strongly constricted so as to appearbinodose; scapepale, the basal se_gment
pruinose; first flagellar segment simple or nearly _so,obscureyellow; secondflagellar segmetttfeebly bicolorous,tlre apex andlonstricted portion being pale, the remainder black; the sqcceedingtwo or three segmentshave the extreme apex pale; theremainlderof the organ black. In the female,the.flagellar segments are simple or very nearly so but the individual segments
are strongly constricted at the incisures. Head light gray witha broken capillary brown median vitta.
Mesonotai ptaetcutum buffy, the lateral margins gray, qh9
ctisk with three brown stripes that are narrowly margined withdarker brown, the median stripe further divided by " capillarydark brorvn vitta; lateral stripes more nearly entire; scutum
buffy, with brown marks on the lobes, the caudal margin andremiining scleritesof the mesonotumclear light gray pruinose;
scutellum"with a very tenuous capillary brown median line.
Pleura gray. Halteres elongate,the stem brownish yellow, theknob dark brown.

Tipula maculipleura sp. n.
Belongs to the tricolor group; closelyallied to T. fl,oridensi's,Alexander; thoracic pleura conspicuouslvmarked with brown.
3. Length about 15mm.; wing about 17 mm.
Generali-ysimilar and very closely allied to T. floridensis,
differing eipecially in the coloration and details of structure of
the male hypopygium.
Antennae bicblorous; wing-apex entirely darkened; whitish
fascia at the cord not entirely traversing the wing.
Thorax yellowish, with conspicuottsbrown markings, including the following areas on the pleura: A large sp.ot on thecephalichalf of the anepisternum;ventral half of the sternop-leuriteand the propleura. The body of the type is discolored
and it cannot be-statedwhether the pleura is heavilv pruinose,cell
as is usual in the group. Wings very similar to fl,oridezsc.r,'C broader and more yellowish.
Abdominal tergites dark, the lateral margins of the segments
broadly pale, the caudal margins more narrowly of this c9!o1;
eighth-tergite with the caudal margin broadly buffy. N{alehypopygium with the ninth tergite dark, the caudal_marginproduced into an elongate median lobe that is a little narrowedshortly before the truncated or subtruncatedapex; surface of
this lobe with microscopicgray setulae;medianarea of the basal
half of the lobe slightly elevatedinto a linear ridge.
