 bilobed, claw-joint long, thin, and setose; claws thin. Elliptic or 

 cylindrical or with an angular outline, convex, densely squamose, 

 fasciculate, punctate, winged. 



The species belonging to this genus appear to be borers in soft 

 dead wood. T. fasciculatus(Le£L) should not have been referred 

 to Tychreits^ and a new genus has been erected to receive it. 



Scape inserted nearer base than apex of rostrum reversus, n.sp. 



Scape inserted in middle of, or nearer apex than base 

 of rostrum. 



Each elytron distinctly produced at apex camelus Pasc. 



Elytra conjointly rounded at apex (or almost so). 

 Prothorax carinate. 



Apical fascicles of prothorax well defined co7')/ssomerns Lea. 



Apical fascicles almost absent sellatus Pasc. 



Prothorax non-carinate. 



Rostrum entirely black /wrrif-s, n.sp. 



Rostrum more or less red. . 



Elytra but little wider than prothorax fumosus, n.sp. 



Elytra fully once and one-half the width of

Tychreus camelus Pascoe; Mast. Cat., Sp.No.5522. 



Moderately long, convex, with an elongated-hexagonal outline.
