 brown, the antennae being rather the darkest.

ISTEISIA, gen. nov. 



This genus has most of the characteristics of Salpinqns. 

 The chief differences are : ten joints of the antennge monili- 

 form, basal joint nearly as large again as the second ; 2-7 

 almost similar, 8-9 thicker and larger than the basal joint, 

 terminal largest and conical ; maxillary palpi, 2 basal joints 

 short, third moniliform, terminal longer but not wider; the 

 legs and tarsi are formed like those in Salpingus. The thorax 

 is gradually narrowed at the sides from behind the anterior 

 angle; the elytra not striate. Having only one example, I 

 give an outline of the body, and an enlarged drawing of the 

 palpi (fig. 1).
