5. SPHENISCOMYIA, Bezzi. 

 Bezzi, Mem. Iiidiau Mus., III, (3), 146 (1913).

Becker considers this genus alliecl to Acidia and distinguishes 

 it by its bare third vein (114 + 5), and the characters of the head. 

 Bezzi States tliat he erroneously called it Sphaeniscus, which name 

 must be amended to Sphenisciis; however, he further states that in 

 this form the nàme is Iwice preoccupied in zoology; in birds (by 

 Brisson, 1760) and in Coleoptera (by Kirby, 1817); he therefore pro- 

 posed the name Spheniscomyia, which I hâve adopted. 



This genus is distinguished by the bare R4 + 5 vein; the well 

 developed costal bristle; the approximate radio-median and médian 

 cross-veins; two pairs of i.or.: by the black shining colour of the 

 body; the absence of bristles ou the abdomen; and by the pattern of 

 the wings, which is like that of some species of Urophora. 



Head broader than high; frons broad but becoming somewhat 

 narrower towards the base of the antennae; face concave and nar- 

 rower than the frons; eyes large and fairly rounded : cheeks narrow^ 

 epistoma not prominent in profile; proboscis .short and palpi small 

 and bristly; antennae placed just after the middle of the eyes, the 

 third joint pubescent, rounded at the tip and about twice as long 

 as the second joint; arista with a very minute and microscopic pu- 

 bescence; oc. strong; s.or.2, i.or.2: rt. long; prt. parallel : geml 

 bristle strong; ocp. well developed. 



Thorax short, globose, entirely black and possessing a complète 

 chaetotaxv; mpl. 1; pt. strong; scutellum .sniall, rounded, convex 

 and entirely black ; scutellar bristles niay either be 2 or 4, in the first 

 case the a. se. are wanting, in the second case they are only a little 

 weaker than the 6.. *■■<". and converging at the apex. Abdomen short, 

 rounded, convex, distinctly narrowed at the base, devoid of latéral 

 or apical bristles. Maie hypopygium small, rounded; female ovi- 

 positor long or médium, fairly broad and flattened. 



Legs short; front femora with a row of 4-5 bristles below: mid- 

 dle tibiae with a single spur. 



Wings normal in shape with a distinct costal bristle; subcosta 

 indistinct; Ri very short, ending a little before the middle of the
