basilar space, together with the humeral callus, strongly thickened ; 

 surface punctate-striate ; on each elytron are placed two large 

 rufo-fulvoiis patches, one transverse, covering the elevated base, 

 and extending from the outer border of the humeral callus nearly 

 to the suture, the other triangular, commencing just below the 

 middle of the elytron and reaching nearly to its apex; the surface 

 covered by these patches is much more finely punctured than the 

 remaining portion of the disk.

 Scelodonta may be known from all nearly-allied genera by the 

 deep grooves on the head, placed one on either side a little above 

 the eye.
