between the faunae of these Islands, a condition by no means unexpected 

 since both ^re located in the same fauna! region. Enough is known to show 

 that these two areas contain many very interesting gall midges. A consider- 

 able number are presurnably unknown and there is therefore every probability 

 of many interesting forms being brought to light as a result of further studies. 

 We would in this connection call attention to the desirability of investigating 

 the non-gall making midges, a group presenting many extremely interesting 

 variations in Doth habits and structure. 



Dasyneura elatostemmae n. sp. 



Midges described below were reared from petiole galls on a species of 

 Elatostemma and bore the following label: Elatostemma sp. Oengaran-Gebirge, 

 altitude 1000 M. 1914, DvL, No. 18, not yet described. There were some ten 

 specimens, both sexes being represented and at least one parasite. 



Male. Length 1.25 m.M. Antennae as long as the body, sparsely haired, reddish 

 brown, 14 segments, the 5th with a stem Î4 longer than the basal enlargement, which 

 latter has a length about twice its diameter, terminal segment reduced, narrowly oval 

 and with no apical stem. Palpi, first segment short, subquadrate, the second with a length 

 about twice its diameter, the third one half longer than the second, more slender and 

 the fourth twice the length of the second, more slender. Mesonotum reddish brown, 

 scutellum and postscutellum yellowish, abdomen yellowish brown, haltères whitish trans- 

 parent, coxae pale yellowish, legs mostly pale straw, claws long, slender, unidentate, 

 the pulvilli about half the length of the claws. Genitalia, basal clasp segment moderately 

 long, stout, terminal clasp segment long, stout, dorsal plate long, broad, very deeply 

 and triangularly emarginate, the irregular broadly rounded lobes sparsely setose. Ventral 

 plate shorter, deeply and almost roundly emarginate, the lobes rather slender, subtruncate. 



Female. Length 1.5 m.M. Antennae extending to the base of the abdomen, 

 sparsely haired, pale yellowish, 14 segments, the 5th sessile, cylindric, with a length 21/2 

 times its diameter. Mesonotum reddish brown. Scutellum and postscutellum yellowish, 

 abdomen brownish yellow. Wings hyaline, haltères whitish transparent, coxae and femora 

 pale yellowish, tibiae and tarsi dark brown. Ovipositor when extended fully as long as 

 the abdomen, the terminal lobes long, ratlTer broad, with a length over ihree times the 

 width. 



Type Cecid. A 3095, N. Y. State Museum.
