ment with a pronounced hump in profile, covered with 

 evenly placed erect black hairs; forceps black, rather 

 stout, bent back on the attached basal j)ortion, which 

 is covered with coarse black hair ; the free part straight 

 nearly to tip, then bending forward to an oblique, out- 

 wardly directed point; from behind, the forceps are 

 quite widely separated from the base. Accessory 

 plates yellow, shining, elongated apically but the bas- 

 al part very short; both claspers dark brown, stout 

 and equally hooked, the anterior shorter. Penis large, 

 basal segment reddish, of moderate size; distal seg- 

 ment large, blackish, shining, notched into two sharp 

 points at tip; on the back just behind these is a pair 

 of divaricate and recurved large hooks, united at base ; 

 viewing the distal segment from obliquely in front, 

 it is strongly protuberant beyond the middle, with a 

 large central orifice, basad of this orifice and on a less 

 protuberant level is a wide rim, extending laterally 

 past the body of the organ into an earlike lobe ; distad 

 of the orifice the shape is like a goat's head, 

 the orifice being its mouth, and back from this 

 (disto-posteriorly) it bears two processes like the 

 horns but with retrorse minute spines ; these processes 

 nearly meet the tips of the segment first mentioned. 

 Fifth sternite widely excised at base, dark, yellow; 

 on each side near the base is a prominent, smooth red 

 process; beyond these the sides approach each other 

 and are covered with black bristles, thence rapidly 

 diverging. 



Legs black, of ordinary structure; middle fe- 

 mora with a comb behind on lower side; middle tibia 

 with two bristles on outer front side; hind tibia with- 

 out villosity. 



Wings almost hyaline; a minute costal spine; 

 first vein bare, third hairv half way to crossvein ; third 

 costal segment as long as fifth and sixth together. 



Length 11-13 mm. 



Five males: four from Tifton, Ga., June 13, 

 1896, in the Hough collection; the other Tampa, Fla., 

 April 29, 1915, collection of A. H. Sturtevant.
