teres pale yellow. Hairs on body and legs yellow, lanceolate hairs on 

 the latter fuscous. 



Eyes distinctly separated above; antennal flagellum with basal 

 joints moniliform, sensory hairs of moderate length, thicker than the 

 ordinary surface hairs. Mesonotum and scutellum with rather numer- 

 ous long hairs. Legs with conspicuous hairs, all tibiae with a dorsal 

 series of lanceolate upright scales ; basal joint of hind tarsi one fifth 

 shorter than second; empodia distinct. Third vein ends at middle of 

 wing. 



Male. — Agrees in color with female. 



The legs are devoid of the lanceolate hairs ; the apical 4 antennal 

 joints are elongated ; the hypopygium is large and very similar to that 

 of spcciilaris; in other respects similar to female. 



Length, .75 mm. 



Type locality, Urbana, 111., June 28, and August 5, 19 15, taken on 

 window in basement of Natural History Building, LTniversity of Illi- 

 nois, by the writer. Allotype, August 12, 1915; same situation. 



The type specimen has a large mite about two thirds as long as the 

 abdomen, firmly attached to it near the base. 



The female of this species will run down to caption 3 in my key to 

 the Illinois species of this genus (p. 312), but may be readilv separated 

 from both species therein by the difference in coloration, and from 

 cilipcs by the possession of lanceolate scales on the fore tibiae. The 

 male can be separated from all others in my preceding paper by the 

 yellow thorax with its conspicuous glossy black vittse. 



One female had a numljer of extruded eggs attached to the apex of 

 abdomen. They are white, about three times as long as thick, slightly 

 rounded at the extremities, and slightly curved in outline. They are 

 closely attached to each other on their longer sides. 



EuFORCiPOMYiA, n. gen. 



Distinguished from Forcipomyia by having the basal joint of hind 

 tarsi much longer than the second, and from Pscudocitlicoides by the 

 different structure of the antenna?, which is similar to that of For- 

 cipouiyia. In Pscudociilicoidcs the antenna of the female has the fla- 

 gellar joints very appreciably constricted at apices, especially the apical 

 5, while in Forcipomyia and the present genus the joints are but 

 slightly constricted and for a very short distance, never having a coni- 

 cal appearance as in Pseudocidicoidcs. 



The wings are densely haired, but the hairs are slender and rather 

 upright, more resembling those on the wings of Pseudocidicoidcs than 

 on Forcipomyia. The first vein runs close to the third and is con-
