SARCOPHAGA AND ALLIES 217 



two, and three with only lateral bristles, the fourth 

 with a marginal row of about a dozen; fifth sternite 

 brownish yellow, the edges not divaricate but touch- 

 ing each other to the tips, which project from the 

 abdomen almost at a right angle, like a shield over 

 the genitalia in repose; outer margins fringed with 

 erect, stiff hairs. 



Hypopygium yellow, both segments rather 

 large and covered with golden pollen; first with a 

 very widely interrupted row of hairs near hind edge; 

 second globose, with erect hairs, none bristle-like; 

 forceps yellow at base, free part becoming black, 

 short, obliquely truncate diagonally at apex, so that 

 the front and inner angle is the longest, with a slight 

 tooth projecting back in profile just behind the tip. 

 Accessory plate triangular, brownish-yellow, the hind 

 edge thin; posterior clasper black, moderately curved 

 and tapering, sharp at tip; anterior clasper yellow 

 at base, strongly curved to a black complex tip, of 

 which the main point is directed forward, a shorter 

 one forms a square angle below, and another projects 

 on the outer side on a level with the first but shorter. 

 Penis with very short yellow basal segment; distal 

 segment dark yellow, with a smooth, hooded apex 

 which greatly overhangs the basal part in front; bas- 

 ally from the hooded part a pair of complicated plates 

 arise from the stalk, lie rather close to the hooded 

 mass, and give off a pair of curved filaments on the 

 basal side. 



Legs black; middle femur with distinct comb 

 on hind side below near tip; middle tibia with one 

 bristle on outer front side and no villosity on inner 

 side ; hind tibia with minute but fairly distinct villous 

 hairs along the middle, spreading both ways, but not 

 much longer than the thickness of the tibia. 



Wing hyaline; no costal spine; third costal seg- 

 ment longer than fifth; first vein bare, third hairy 

 nearly to crossvein. 



Female. Front .276 of head (average of five, — • 

 .270, .272, .276, .278, .283), golden as in male, orbitals
