This closely resembles X humilis, but the areolcts of the thorax 

 are not so well defined ; the elytra have the same four strong costre, 

 but the transverse costas are black, less distinct and much closer 

 together, and the interstices have a more woolly appearance.

This differs from X. fumigatus in having only a single lanceolate 

 areolet in the middle of the thorax. The interstices of the elytra 

 are very woolly and the transverse costse are rather obscure and 

 very close together.
