Corymbites Latr. 



C. granulicollis (figure 1). — Body rather short and stout. 

 Head about equal in length and breadth, front apparently 

 transversely rugose; antennae broken, but the remaining por- 

 tion shows them to have been rather slender and only very 

 little serrate, probably not attaining the hind angles of the

thorax. Prothorax emarginate and narrower at apex, grow- 

 ing broader with equal lateral curve to about the middle, then 

 arcuately narrowing to a point just anterior to the posterior 

 angles, which are rather markedly divergent and distinctly uni- 

 earinate; the disk with small closely placed granules, each 

 with a minute central puncture. These granules become 

 much finer and more crowded near the sides, and a median 

 basal area (which may have been canaliculate) is nearly devoid 

 of them. Elytra finely alutaceous, finely and sharply striate 

 but not punctured. Anterior leg (the only one visible) short, 

 second, third and fourth tarsal joints about equal.
