GoNYPus, Lat. — Leptogaster, Meig. 



The stilet terminates in a short seta. The abdomen is long and al- 

 most linear, and the tarsi are arcuated *. 



In the others, Hyholini, Lat., the head is more rounded, almost en- 

 tirely occupied by the eyes, in the males, and its epistoma frequently 

 naked, or but slightly pilose. The probosis is very short. The 

 Avings present fewer nerviires than those of the preceding ones, and 

 their inner portion is destitute of that complete triangular cell, 

 whose point rests upon the posterior margin, or at least it is merely 

 rudimental. 



Sometimes the last joint of the antenna? is large, fusiform, elon- 

 gated, and terminated by a very small stilet. 



CEdalea, Meig. 

 Sometimes the last joint is ovoid, short, or conical, and with a long 

 seta f. 



Hybos, Meig. Fab. — Damalis, Fab., 

 Where the posterior thighs are large and inflated \. 



OcYDROMiA, Hojfm. Meig., 

 Where they are of an ordinary size §. 



Empis Lin. — Empides, Led., 



Closely allied to Asilus in the form of the body and the position of 

 the wings, but with the proboscis perpendicular or directed back- 

 wards. The head is rounded and almost globular ; the eyes very 

 large. 



These Insects are small and live on prey and the necter of flowers. 

 The last joint of their antennae is always terminated by a biarticu- 

 lated or short stilet, or by a seta. The males of some species — Hi- 

 larics — have the first joint of the anterior tarsi strongly dilated. 



Some have triarticulated antennae. 



Sometimes the last joint forms an elongated cone. 



Here the proboscis is much longer than the head ; the biarticulated 

 stilet terminating the antennae is always short. The palpi are always 

 turned up. 



Empis, proper. 



Such in Europe is the 



E. pennipes. Fab. ; Panz., Faun. Ins., LXXIV, 18. Black, 

 with obscure wings ; posterior legs of the female furnished with hairs 

 resembling feathers.

t Idem. M. Macquart, Dipt, du nord de la France, has established two new 

 genera in this division ; Microphora, similar to ffidalea in the elongation of the 

 third joint of the antennae, but with an elongated stilet; and Lemtopeza, closely 

 allied to Ocydromia, but with the stilet entirely terminal, whilst in the latter it is 

 inserted in t!ie back of the third joint, a little beneath its extremity.
