A much more elongate and narrow species than A. 

 coloratus, Blackb., with the facies of a somewhat narrow 

 Haplonycha. The antennae are structurally much like those 

 of A. coloratus, but decidedly longer and more slender, the 

 maxillary palpi very different, but not more so than is fre- 

 quent between species of Haplonycha. The abdomen short, 

 strongly punctulate, and with extremely strong ventral 

 sutures is characteristic of both species.
