Tijds. v. Ent. xxix. 1886, p. 252. 



The characteristics of this species are the three independent 

 foveas of the prothorax, and the absence of the transverse furrow; 

 the colour is rather dark reddish, with the. legs and palpi pale 

 testaceous ; the palpi are moderately long, little sinuate, the 

 peduncle in the 4th joint is a little longer than the club.

The longitudinal furrow of the head is shallow behind, but 

 extends, however, as far back as the neck; the antenna? are long, 

 with the club well marked and all the joints are oblong; the palpi 

 are rather long, the peduncle in the 4th joint is arcuate and longer 

 than the club; in the posterior part of the prothorax is a curved 

 not interrupted furrow, and the space between the furrow and 

 the base is reticulate and opaque. The <J has a very prominent 

 character consisting of two tubercles situated close to each other 

 on the very edge of the second ventral segment.
