sometimes united along the middle of the disc ; the corium rufous or reddish-ochreou 
with tbe apical margin narrowly ochreous. The males have the apex of the terminal 
genital segment broadly produced in the centre, and armed on each side with a — 
moderately long, divergent, upwardly-curved spine, which is distinctly hooked at the 
tip (the armature resembling that of A. subpiceus and its allies, and very different from 
that of A. pictipes) ; the claspers are comparatively short, very abruptly bent inwards 
a little beyond the middle, and strongly curved at the apex. ‘The females have the 
outer apical angles of the first genital segment deflexed and dilated into a subtriangular 
concave plate (this being much larger than in the same sex of A. flaviventris and 
A, pictipes); the terminal genital segment is strongly transverse. The single ( ? ) 
specimen from Omilteme has the pronotum black, with a small spot on each side 
of the posterior lobe in front and the anterior angles rufous, and the corium obscure 
rufo-piceous.

Five specimens from Mexico are referred to this species. They differ from the 
normal form of A. spissipes in having the pronotum black, with the basal margin 
flavous, the connexival margins more distinctly bordered with reddish or flavous, and 
the corium dark. This system of coloration, however, seems to be quite constant in 
the numerous North-American examples seen, except that the latter have the lateral 
and apical margins of the pronotum also reddish. The external genital structure in 
both sexes is similar to that of A. spissipes.
