In contour not unlike the last insect described, but the coloration differs; the 
pronotum is much darker and more shining, with a whitish patch on the metopidium ; 
the tegmina are dark fuscous at their bases, and they have each a broad and squarish 
ochreous space enclosing the apical areas and the extreme border ; the legs dark 
ferruginous ; the hind tibiae have a dark line down their middle. 
Size, 8x4 mm. 
Habitat. —Panama, Volcan de Chiriqui, 4000 feet. 
Closely allied to A. hadina, Butl., and to A. pugionata, Germ,, which last two insects 
may prove to be identical. 
The frons and metopidium are very pubescent.

Walk. l.c. Suppt. p. 135; Fowl. l.c. Tab. V. figs. 9, 9a, p. G2. 
This is a large and handsome species, and may be considered as typical of the genus. 
The pronotum is black, with a shining steel-blue glance, and it quite covers the body 
when the wings are folded. From the back view, the anterior part is almost as acute 
as the posterior, and it shows a sharp carina or dorsal ridge ; the tegmina are slightly 
fuscous and subhyaline ; the areas are long and narrow, and the neuration dark 
brown ; legs short; the abdomen greyish, plump, and distinctly segmented ; the 
metopidium by the front aspect, and the frons below it, appear conical in form. 
My figure is that of a male, with the expanse of wings equal to 19 x 12 mm. 
The frons and the metopidium are thickly set with pale ochreous yellow fine hairs. 
The dorsal carina is continued over the front and the back edges of the procephalic 
process.
