Head exserted, rufo-piceous, coarsely but not closely punctured ; 

 epistome wedge-shaped, its apex not separated from the front, an- 

 terior border angulate-emarginate ; jaws black. Thorax as broad 

 as long; sides angled just behind the middle, in front of the 

 angles slightly rounded and converging to the apex; anterior and 

 posterior angles each armed with an obtuse tooth ; above subcylin- 

 drical, deeply, coarsely and closely punctured ; middle portion of 

 anterior border broadly rufo-piceous. Scutellum elongate-trigonate, 

 its apex obtuse. Elytra much broader than the thorax, oblong, 

 deeply excavated below the basilar space, the latter thickened, 

 nearly impunctate ; within the humeral callus is a deeply sulcate 

 stria, the callus itself prominent; striae below the basilar space and 

 on the surrounding space coarsely punctured, punctures finely im- 

 pressed on the middle disk, entirely lost towards the apex ; hinder 

 third rufo-piceous ; at the base is a large transverse fulvous 

 patch which entirely covers the basilar space. 



23. Nodostoma b'lpustulatum, n. sp. 

 Subelongatum, convexum, pallide piceum, nitidum ; antennis 

 pedibusque obscure fulvis ; thorace lateribus rotundatis, pone 

 medium obsolete angulatis, disco sub fortiter remote, ad 

 latera profundius subcrebre, punctato; elytris oblongis, tho- 

 race paullo latioribus, infra basin et intra callum humerale
