There is a series of specimens from the same localities which I cannot specifically 

 separate from Aiuicerastes geometricus ; the bands are much less marked, sometimes 

 entirely obsolete, the pubescence is much more ashy colour, so that the dark postmedian 

 patch on each elytron is more obvious, and the inters[)aces of the elytra ai"e faintly 

 marked here and there with fuscous. I jiropose to name this form ah. cinerascens.
