450 REVISION OF THE AMYCTERIDES, V., 



finer below and reaching almost to coxse. Elytra (6 x 4-5 mm.) 

 subparallel on sides, shoulders rounded ; base, from certain 

 directions, appearing very feebly emarginate; striae shallow, 

 punctures small, open, rather indefinite; interstices with small 

 granules, the third and fifth slightly more elevated, with some- 

 what larger granules; lateral interstices non-granulate. Under- 

 surface somewhat depressed at base; with large punctures sepa- 

 rated bv narrow ridges, forming an irregular reticulum, these 

 punctures most marked on second and apical portion of first 

 segment, obsolescent on metasternum. Anterior coxpe con- 

 tiguous; anterior tibiae feebly curved, posterior feebly incurved. 

 9. More ovate; undeisurface convex, with fewer and smaller 

 punctures, not reticulate. Dime^isions : ^, 10x4-5 mm.; 5, 

 10x5 mm.

The onlj' species known to me at all similar to the above, is 

 the species I have identified as C. Mussoni Blackb.; from that 

 species, the present one differs in the coarser, prothoracic gran- 

 ules, and in the different ventral'punctures. 



The head, with its outwardly and upwardly directed crests, 

 is reminiscent of Notonophes, but the structure of the pi'othorax 

 clearly shows the aftinity of C. auriculatns to the Cubicorrhyn- 

 chus-Acantholophus complex. The basal ti'ansverse impression 

 or sutterinir is concealed from above, but can be seen from the 

 side; when viewed from the side, the posterior portion of the 

 lateral margin is seen, to bend downwards to the latero-basal 

 angle. 



It is possible that C . auriculatus and C. Mussoni should be 

 separated from Cubicorrhynchus, but I do not think that they 

 can be referi'ed to Acantholophus.
