TRIBE. 



LISTRODROMIDES. 



This tribe constituted Forster's thirty-second family, the Listrodromoidae, 

 distinguished from the remainder of our Ichneiiinoninae by the pectinate 

 onyches ; it is, however, an extremely artificial division, since those of 

 the $ are simple and differ only in their relatively small size from the 

 onyches of the Joppides, which tribe members of the present resemble in 

 their strongly convex scutellum, short metanotum, and deeply impressed 

 incisures, but they may be at once distinguished therefrom in both sexes 

 by the entire absence of lunulae on the second and third segments and, at 

 least in the European exponents, by the small, indistinct, more or less 

 circular metathoracic spiracles. 



Thomson, on the other hand, considered the two following genera 

 formed, with Anisobas, a small, compact group among the Amblypygini 

 sharing the following characters in common : — Clypeus not discreted,
