AuLACUS, Jurine. 



This genus, founded by Jurine, differs from Fcenus, in having 

 the veins of the wings disposed in the ordinary manner, and in 

 the slender hind legs and shorter abdomen, in which respects it 

 assumes much of the ordinary appearance of some of the Ichneu- 

 monidce. Like Fcenus it has the ovipositor long, and formed as in 

 that genus, and the antennae are composed of thirteen joints in the 

 males (PI. XIV. fig. 8«) and of fourteen in the females (fig. Sb). 

 No figures of the Trophi having hitherto been published, I have 

 added the details of the mouth of J. Palrati, taken from a male 

 specimen; but as that was the sex dissected by Latreille* (vide 



* In the details of tl'e inoulh of this genus, as well as of Fxiins, Esenbcck 

 has relied upon liatieillc's description, copying it almost vcibatim without ac- 

 knowledgmcnt.
