NORTH AMERICAN BUPRESTID BEETLES 75 



pronotum is widest at the middle, and the sides are arcuately 

 rounded. The two median depressions are slightly variable in depth, 

 and some examples have a very short, distinct, prehumeral carina 

 on each side. The elytra sometimes have the longitudinal costae 

 vaguely indicated, and the prosternal lobe has the front margin 

 subtruncate to broadly, feebly emarginate. 



Host. — This species has never been reported as being reared, so 

 the host is unknown. Frost (1915, 1920) records collecting adults on 

 the leaves of red raspberry and oak. 



The males of this species are easily separated from those of the 

 other North American species of this genus by the antennae, which 

 are longer than the pronotum and clothed on the under side with 

 long hairs. Horn (1891) writes that the females have the antennae 

 similarly pilose, but I have failed to find these long hairs on the 

 antennae of any of the females associated with the males; even the 

 females in the LeConte and Horn collections under crinicomis (if 

 they are the females of this species) have the antennae shorter than 

 the pronotum, and without long hairs on the under side. I am 

 unable to satisfactorily separate the females of this species from 

 those of otiosus and allied species.
