 body 1 34 lines. A pair taken in the Expedition, 



Very near A. domestka (A. lunbata F.) but distinct. Body piceous or

 Ent. Soc, 1868) states that this species is taken from " Maine to Alaska. 

 In tlie ^ the head is concave, and the thorax finely transversely asperate 

 before the middle ,; in the % the head is convex, and the thorax much 

 more roughly asperate. This species varies greatly in colour. *he black 

 elytral vitiae sometimes occupy nearly the whole surface,, ana sc; netimes 

 are almost wanting."]
