more than half the size. The proboscis is long and rather 

 slender, the maxillary palps are broad and as long as the 

 proboscis, there are no hairs on the lower border of the 

 antennal bristle, and the 4th longitudinal vein is gently 

 curved beyond the cross-vein. Fig. 61 represents a female 

 Lyperosia full of eggs and with ovipositor protruded, seen as 

 a transparency mounted in balsam. The eggs of Lyperosia 

 irritans, L., are said to be deposited on fresh cow-dung and 

 to be reddish-brown in colour.

Hcematobosca, Bezzi {alua = blood ; /3ocrKeiv — to feed). 

 Represented in Europe, North India, and China. As in 

 HcBtnatobia the arista has a few hairs on its lower border, 

 and the maxillary palps are spatulate and as long as the 

 proboscis ; but the 4th longitudinal vein is strongly curved 

 distally so as to narrow the ist posterior cell very much, and 

 there are no bristles on the 3rd longitudinal vein. 



Stygeromyia, Austen (o-Tuye/oo? = hateful ; ^xvla = fly). 

 Known from Arabia and Tropical Africa, and resembles 

 Stomoxys in general appearance. The arista is feathered on 

 the upper border only, the proboscis is remarkably short and 

 stout, the maxillary palps are spatulate and as long as the 

 proboscis, the 3rd longitudinal vein has a few bristles at its 

 proximal end, and the 4th longitudinal vein is strongly bent 

 distally.
