BYCEenr.BsP. ALEXANDER
Prof.of Entomology,Massachusetts
Amherst,Mass.,U. S. A.
State College,
The first part under this general title was published in the<RevistaCh-ilena
de HistoriJ Naturalr, vol. 38 z 173-179;1934.
In the present paper I wish to discussfour new speciesthat
were included in rich Tipulid materials recently sent to me
by ProfessorDillman S. Bullock, chiefly taken in \'[alleco.
I am indetreted to ProfessorBullock for the privilege, of retaining the materialsin my own collection.

Tipula tri-emarginata, sp. n.
Belongsto the glaphyro.ptera
group; allied to brethesiana
and jacobs'inna;mesonotal praescutum grey, with five brown
stripes, the median vitta strongly narrowed at anterior end;
posterior sclerites of mesonotumwith a median dark line;
antennae (male) relativelv long, the basal flagellar segments
bicolorous;femora yeilow, the tips narrowll' and wearklyinfumed; wings almost uniformly tingedwitir browu, only slightly variegated by darker brown and pale areas; darkenings
in cell ,Scpale brown and but little-evident; abdominal tergites yellow, trivittate with brown, the outer segmenstmore
uniformly darkened; male hypopygium with the caudal border of tergite with three emarginations,the four lobes thus
formed truncate; outer dististyle with a small terminal spatula, occupving about one-third the total length; eighth sternite trilobed, the median lobe a little longer than the laterals.

tip of Scz, cell Scr thus being narrowi Rr relatively long, exceedingone-half the secondsection of Rr; petiole of cell Mr
shorter than m.
Basal abdominal tergite buffy-yellow; succeedingtergites
yellow, with three continuousnarrow brown stripes, on sixthand outer segments more uniformly darkened; sternites buffy-yellow, with a narrow merlian dark line. Male hypopy'giumwith the caudal margin of the tergite ([.6m. VII fig. 1, 9t)
conspicuouslythree-notched,the four lobes thus formed truncated at tips. Ventral lobe of basistyle betweenthree and fourtimes as long as thick, tufted with long vellow setae that are
subequal in length to the lobe. Outer dististyle (fiS. 2, od)
slender,with about, the distal third dilated into an oval spatula that is providecl with long compicuoussetae; stem glabrous. Eighth sternitewith the appendage(fig. 3, 8.s)trilobed,
the lateral lobesshorter than the median, eachbrc;aderat basethan at tip; nredian lobe with conspicuouserect pale setae,
its distal portion rather strongly narrowed.

By my key to the Chi,leanspeciesof Mol,ophil,us(Dipt. Patagonia and South Chile, 1929,pp. 200-202)the present flyruns to M. tetracanthusAlexander, wicll differs in the large
size, with broad, fully-developedwings, the dark colorationof the body, and the detailp of structure of the male hypopygium. The antennaeof the presentfly are of an unusuallength
for a member of this particular subgroupof the genus.
