Male. Front narrow, .133 of the head; sides and 

 face yellowish silvery ; paraf acials rather narrow, with 

 only a few perceptible hairs, on the lower part; an- 

 tenna? brown, third joint three times the second, yel- 

 low at base, reaching four-fifths of the way to the vi- 

 brisscT, which are at the oral margin ; arista very long, 

 long-plumose over half its length; facial ridges with 

 only a few hairs above the vibriss^e; palpi and pro- 

 boscis black, ordinary; bucca one-fourth the eye- 

 height; back of head with dark hairs, only about the 

 foramen and below w^ith yellowish beard; outer ver- 

 tical not differentiated. 



Thorax ( not very well preserved ) with 3-5 black 

 stripes ; 3 ps dc ; 2 stpl ; anterior acr present ; scutellum 

 with 3 marginals (intermediate small), 1 very small

 sternites 1-4 widening successively. 



Hypopygium red; first segment globose behind,

 row of bristles on posterior margin; second segment 

 red, globose, hairy; forceps red except apex, short and 

 broad, with a notable tuft of black, crinkly hairs 

 crowded on a restricted area at base; the accessory

 flat, rather long, rounded at tip, and bears a series of 

 little teeth, which appear normally to face the forceps, 

 — quite unlike any other species known to the writer. 

 Posterior claspers much longer and wider than the 

 anterior, not excised in front to form a claw at tip; 

 penis with a rather small distal median part turned 

 forward, and two much larger subdistal lateral lobes,
