, mature colour bronze yellow or brown, rarely dark brown. Surface of the pronotum reticulate, dull, with sparse and shallow, obscure punctures. Striae of elytra weakly impressed, interstriae gently rounded, micro-shagrinate, dull. Female declivity usually with a long tuft of yellow hair-like setae (sometimes abraded in older specimens), never with two patches of micro-sensillae within the tuft.

Remarks
. This species is very similar to
C. cinereus
but can usually be distinguished by the less elevated interstriae of the elytra which has a micro-shagrinate texture, by the strongly reticulated pronotum that appears more finely shagrinated with fewer and obscure punctures, and that the female elytral declivity lack patches with micro-sensillae. In his original description of
C. subcribrosus
,
Eggers (1933)
also noted the gently rounded interstriae and 'skin-like' appearance of the cuticle: "Zwischenräume auch ganz flach, fein hautartig gerunzelt". Exceptional specimens do overlap in this character, however, and longer series from each locality is sometimes needed to obtain correct identification based on morphology only. These problems are well illustrated by the fact that Eggers also mixed the two species in his own collection in NHMW (Knizek, pers. obs).
