vialis Felt and P. cornea Felt, both received earlier from the 

 same correspondent. These last two species are congeneric with 

 the one to be characterized and now referred to the genus Dy- 

 odiplosis. 



$ Length 2 mm. Antennae one-half longer than the body, thickly 

 haired, yellowish brown; 14 segments, the stems with a length one 

 and one-fourth and two and one-half times their diameters, respectively, 

 the distal enlargement with a length one and three-fourths greater 

 than its diameter and only slightly constricted near the basal third as 

 compared with D. fluvialis. The circumfili are fine and moderately 

 long ; terminal segment produced, the basal portion of the stem with 

 a length three times its diameter, the distal enlargement cylindric, with 

 a length fully three times its diameter and apically a moderately stout, 

 rather long, conical process. 



Palpi; first segment short, irregular, with a length about one-half 

 greater than its diameter, the second a little longer and broader, the 

 third about as long as the two preceding, more slender. 



Mesonotum purplish brown, the submedian lines and posterior me- 

 dian areas yellowish. Scutellum and postscutellum mostly pale yellow- 

 ish. Abdomen sparsely haired, a variable dark brown basally, yellow- 

 ish brown apically. 



Wings hyaline : halteres yellowish basally, light brown apically. 



Legs mostly a pale straw. 



Genitalia; basal clasp segment moderately long, stout; terminal clasp 

 segment distinctly swollen basally. tapering; dorsal plate deeply and 

 triangularly emarginate, the divergent lobes narrowly rounded; ventral 

 plate long, broad, subtruncate apically, the posterior border slightly 

 and roundly emarginate ; style a little longer than the ventral plate. 



9 Length 3 mm. Antennae nearly as long as the body, sparsely 

 haired, dark reddish brown; 14 segments, the fifth with a stem one- 

 third the length of the cylindric basal enlargement, which latter has 

 a length about four times its diameter and sparse whorls of stout 

 setae subbasally and apically ; terminal segment hardly produced, the 

 enlargement with a length three and one-half times its diameter and 

 apically a rather broad subconical process. 



Abdomen sparsely haired, mostly dark reddish brown, the seventh 

 segment and the lobes of the ovipositor yellowish brown; halteres yel- 

 lowish basally. reddish brown apically ; claws long, rather slender 

 strongly curved apically, the pulvilli a little shorter than the claws. 



Ovipositor short, tapering, the lobes with a length over twice the 

 width and tapering irregularly to a narrowly rounded, setose apex. 

 Otherwise as in the male. 



Type — Cecid. a 2782.
