Variation. — The specimens examined show no variation except 

 in size. 



Host. — Unknown. Blatchley (1919) records collecting adults on 

 huckleberry and other low shrubs. 



This species is not common in collections, and so far, has only been 

 recorded from Florida. It has been more or less confused in the 

 literature, as LeConte (1859) misidentified this species as arcuatus 

 Say. and cupricollis has been considered as a synonym of arcuatus 

 by many of the later writers, although it is quite distinct from the 

 species described as arcuatus by Say. Horn (1891) corrected this 

 error and placed arcuatus LeConte (not Say) as a synonym of 

 cupricollis. This species resembles ruficollis Fabricius, but can be 

 easily separated from that species by the absence of the projecting 

 carina on the pygidium, and also by the distinctly deeper depres- 

 sions on the pronotum.

Feirvale. — Form similar to fuscipenms, and rather strongly shin- 

 ing ; head yellowish bronze, more or less cupreous on the occiput, and 

 becoming blackish in the depression; pronotum reddish cupreous, 

 with the sides densely clothed with bright orange yellow pubescence 

 and efflorescence, and the median depression and a round spot on each 

 side along anterior margin bluish black ; elytra black, with a distinct 

 greenish tinge ; beneath piceous, and more shining than above. 



Head with the front not quite as wide as in fuscipennis, slightly 

 wider at top than at bottom, the lateral margins obliquely expanded 

 from bottom to top, with a broad, deep, triangular depression on the 

 vertex and occiput, a deep, longitudinal, concave depression extend- 

 ing from it to the epistoma, and a narrow, transverse depression 

 behind the epistoma and antennal foveae; surface coarsely, sparsely, 

 irregularly punctate, slightly, longitudinally rugose on the occiput, 

 and clothed with a few semierect hairs behind the epistoma ; epistoma 

 narrow between the antennae, slightly elevated, and broadly but not 

 very deeply, arcuately emarginate in front; antennae extending 

 nearly to middle of pronotum, serrate from the fourth joint, and 

 the outer joints slightly wider than long; eyes large, rather broadly 

 elongate, and equally rounded above and beneath.
