Genus TRICHIOSOMA. 



Trichiosoma, Leach, Z. M., iii, 108 (1817). 



Blotch absent. Labrum large, clypeus with a distinct emargination . 

 Posterior femora large, long, toothed beneath. Coxae widely separated ; 

 anterior coxaa slightly apart. Body covered with long hairs. 



The neuration and the form of the antennae agree 

 with Oimbex, as does also the form of the head. The 

 clypeus is much smaller, the labium is much larger, and 

 it projects considerably. The mandibles are large, 

 and have two blunt teeth in the middle ; they are much 

 larger and gaping with the <$ . The labium has three 

 equal lobes, and is rather short and thick. With the 

 labial palpi the second joint is the longest, the first the 

 smallest, and the third is longer than the fourth. The 

 maxilla is long and narrow, its inner lobe is shorter 

 than the outer. The basal four joints of maxillarj^ 

 palpi are thicker than apical. Joint one is a little longer 

 than second, the third is as long as the basal two 

 together, fourth a little shorter than the fifth ; the 

 sixth is the longest.
