This species bears a strong resemblance at first sight to Sthenarus 

 Hotermundij but its longer and different coloured antennae and 

 cuneus will at once separate it from that species. It appears to be 

 intermediate between A. ambiguus and A. variabilis, but it is less 

 than the former, and considerably larger than the latter. Erom 

 ambiguus the $ may be distinguished by the pale 3rd and 4th 

 joints of the antennae, and the ? from the 1st joint being entirely 

 black. In A. variabilis the antennae are pale. 



An abundant species in June, and beginning of July, at Eltham, 

 on apple trees.
