fornica O. S., but is very much smaller and lacks the limpid spaces 

 in the wing markings of that species. 



Dicranomyia aquita, sp. n. (Fig. 28). 



Yellowish fuscous. The subcostal vein ends before or but 

 little beyond the origin of the prsefurca, its cross-vein at some dis- 

 tance from its apex; stigma light fuscous; discal cell closed. 



Fig. 28. Dicranomyia aquita, wing. 



Male — Length 7 mm.; wing 9.5 mm. 



Head gray; rostrum yellowish, more than one-half the length 

 of the head. Palpi and antennae fuscous, basal joints of flagellum 

 incrassate ovoidal, outer joints elongate, beset with short hairs, 

 but no whorls; occiput beset with short blackish hairs. 



Thorax — Collare sordid yellow and, like the neck, brown 

 above; mesonotum grayish fuscous; three broad, but ill-defined, 

 darker stripes; scutel and metanotum grayish; pleura sordid, 

 yellow; sterno- and upper part of pteropleura infuscate. Halteres 

 pale, knob fuscous. Legs yellowish, apical part of femora slightly, 

 of tibia? markedly, fuscous; first two joints of tarsi light fuscous, 

 remaining joints darker. Wings hyaline with faint grayish tinge, 

 immaculate, stigma slightly infuscate, the subcostal vein ending 

 same distance before — in some specimens almost opposite or at 

 most very little beyond — the origin of the praefurca, its cross-vein 

 rather remote from the apex, praefurca longer than vein three from 

 beginning to anterior cross-vein, discal cell closed, the costal 

 margin very closely beset with short, blackish hairs. Abdomen 

 yellowish, with broad median, fuscous stripe, the lateral margin 

 indistinctly margined with fuscous; hypopygium concolorous, the 

 part supporting the large pleural lobes velvety brown. 



Female — Length 8 mm.; wing 8.5 mm., similar to male; basal 

 joints of antennal flagellum scarcely incrassate; the lateral margins
