In structure of the rostrum, pubescence of the antennae, structure and foim of 

 the pygidium, this species is similar to A', saperdoidea Gyll. 



The pattern of the upper surface is somewhat variable ; the dorso-lateral narrow 

 line on the prothorax varies from being almost complete to being slightly indicated 

 only at base and apex ; the sutural stripe on (he elytra is sometimes of e\en breadth, 

 whereas it usually is somewhat dilated behind base and behind middle. Besides the 

 four lineolae on the elytra mentioned in the description there are often two more 

 markings, one behind the shoulder, the other in the middle, both lateral ; the outer 

 margin is also thinly bordered with luteons in some specimens.
