hyperhoreus, but a closer examination showed so many points of distinction 

 as scarcely to warrant such a conclusion. The pubescence, for instance, is 

 shorter, blacker, and thinner; the tegulae are quite black, the legs much 

 more darkly coloured, the costa and stigma are not so clearly white, the 

 vertex has the puncturing more rugged, the labrum black. 



Very rare. Imago end of June. Larva unknown.
