NEOTROPICAL DORILAHLE (PIPUNCULID^) 
STUDIES, PART 1 (DIPTERA)* 
By D. Elmo Hardy 
Assistant State Entomologist, Ames, Iowa 
This paper deals with the new species of Neotropical 
Dorilaidae in the collection of the Museum of Comparative 
Zoology, Cambridge, Massachusetts. These were kindly 
loaned to the writer for study by Dr. Joseph C. Bequaert. 
The species herein described will be keyed in a monograph 
of the Neotropical Dorilaidae which is being prepared. 
Dorilas (Dorilas) latifrons n. sp. 
(Pigs, la-b) 
This species is related to D. flavitarsis (Williston). 
The species is distinguished by the broad front and nar- 
row face of the female, the presence of well-developed 
flexor spines on the femora, by having the r-m crossvein 
at the basal third of the discal cell and the last section of 
the fourth vein not sinuous. 
Female. Head: Front very broad, expanded in the 
middle, gray on the sides and with a polished black ridge 
running its entire length down the middle. At its widest 
point the front is two times wider than the ocellar triangle. 
Face very narrow, at its narrowest point it is about equal, 
in width to one eye facet. The occiput is chiefly gray 
brownish on the upper portion behind the vertex. The 
labellum and the third antennal segment are yellow, the 
palpi and the first two antennal segments are brown. The 
third segment is acute at apex (Pig. la). Thorax: Dor- 
sum black in ground color, sides yellow brown. Mesono- 
tum and scutellum chiefly brown pollinose, pleura gray.
