4 SOUTH AMERICAN TIPULIDAE 



The general European holocaust had its effect down in 

 Peru, for the bank in which my money was deposited was closed 

 and I had to go back to the United States. 



Family TIPULIDAE 

 Subfamily Limnobinae 

 Tribe Limnohini 

 Genus DICRANOMYIA Stephens 

 Dicranomyia virilis sp. n. 



Thoracic dorsum with four stripes; femora broadly tipped with yellowish; 

 wings pale yellowish subhyaline; abdominal segments with a pale terminal 

 annulus. 



Female. — Length, 8.5 to S.6 mm.; wing, 10.8 to 11.2 mm. 



Rostrum and palpi dark brown. Antennae with the basal segments dull 

 yellow, flagellum dark brown; the segments of the flagellum oval or slightly 

 elongate oval. Head light gray. 



Pronotal and cervical sclerites prolonged, dark brown. Praescutum red- 

 dish-brown with four dark brown stripes, the middle pair being long and narrow, 

 extending almost the entire length of the sclerite; lateral stripes shorter and 

 broader, the entire sclerite sparsely .pollinose; scutum with the lobes dark, 

 median area paler; scutellum pale gray on the basal two-thu'ds, the caudal 

 third dull yellow; postnotum brownish yellow, sparsely gray pollinose. Pleura 

 dull brownish yellow, the dorsal sclerites darker brown. Halteres rather long, 

 slender, pale yellow, the knob dark brown. Legs with the coxae reddish yel- 

 low; trochanters dull yellow; femora light brown, toward the tip slightly 

 darkened, the actual tip broadly pale yellow; tibiae and tarsi brown. Wings 

 pale yellowish subhyaline, stigma oval pale, veins brown. Venation: (see 

 plate I, fig. 5) Sc moderately long, Sci about one-fifth the length of Sci) the 

 tip of Sci opposite or slightly before the origin of Rs; Rs long, arcuated, twice 

 the length of the basal deflection of R4+-0', basal deflection of Ciii just before 

 the fork of M. 



Abdominal tergites dark Ijrown, the caudal margin of the sclerites slightly 

 paler; sternites dull yellow. 



Habitat. — Peru. Holotype, 9 , Matucana, Peru, altitude 

 7788 feet, July 14, 1914. (Parish coll.) Paratype, 9, topo- 

 typic. 



This species suggests D. insignifica Alexander - in the wing- 

 venation but the thoracic dorsum is quadrivittate instead of 

 trivittate, the femora are conspicuously paler at their apices, 

 the segments of the abdomen ringed with paler at the caudal 

 margin and other characters are different.
