HyEMOBORA PALLIPES. 



Order Omaloptera. Fam. Hippoboscidae. 



Type of the Genus, H. pallipes Curt. 



H^MOBORA Curt. 



AntentKE inserted close to the anterior angles of the clypeus, globular, 



hairy, and sunk into the head (2 a). 



Labrum horny, elongated, hollow, slightly arcuated, inclosing the 



tongue. 



Tongue nearly as long as the labrum, slender. 



Lip horny, arched, hollow, inclosing the labrum and tongue (1 g). 



MaxiUce} rigid, obtuse, ciliated with strong hairs, united at their in- 

 ternal edges, bent downwards, inclosing the proboscis, and extending 



beyond the head hke a beak (1 and 2 e). 



Mentum large, coriaceous, membranaceous, covering and concealing 



the base of the proboscis (\ h). 

 Head broader than long, somewhat transverse-ovate, closely adhering to the 

 thorax : eyes large very remote : ocelli 3 in triangle. Thorax a little 

 broader than the head, nearly quadrate, dilated near the base of the wings, 

 notched anteriorly : scutellum broad and short. Wings very long and 

 rounded, frst marginal or mediastinal cell extending one-third the length 

 of the wing ; 2nd marginal cell very long, rounded at the end, discoidal 

 cells waited, 6 obscure and imperfect nervures extending to the posterior 

 margin : Halteres very distinct and capitate. Abdomen small, nearly co- 

 nical, peduncled spongy, coriaceous towards its base. Legs thick, first pair 

 remote from the others, and inserted almost under the head : tarsi 5-jointed, 

 terminal Joint the longest : claws lengthened at their base on each side the

Shining, pale and dull greenish-yellow, clouded with brown, with 

 strong hairs scattered over the body and legs : eyes and claws black : 

 thorax beneath punctured and covered with short strong erect hairs : 

 wings nearly transparent, nervures yellow, the costa sUghtly ciliated.

Tlie curious tribe to which this insect belongs forms a 2njd divi- 

 sion of Latreille's Diptera, and is called Eproboscidea. Dr. Leach, 

 who investigated the species with great attention, and published his 

 observations in the second volume of the " Wernerian Transactions," 

 subsequently constituted them into an Order, the propriety of which 

 cannot be doubted when we consider that these insects are very dif- 

 ferent to the Diptera both in structure and oeconomy. 



The genus that I have proposed appears to connect Hippobosca 

 (PI. 4-21) and Ornithomyia. It will be seen that my ideas regarding 

 the mouth differ from those of other authors ; but as an universal
