Allied to A. percheron (Guerin) from Cayenne and St. John, 

 West Indies, but differing in the small exposed portion of the wings, 

 the greater size and the entire absence of ochraceous coloration from 

 the insect, the general tint being dull blackish brown. 



Size medium ; body moderately depressed, subfusiform. Head cordiform, an- 

 tennae moniliform, 15-16 jointed. Pronotum subquadrate, the anterior and lateral 

 margins straight, the posterior rotundate; centrally with a longitudinal depres- 

 sion. Elytra rather elongate, posteriorly subtruncate, the surface slightly scab- 

 rous. Wings projecting beyond the elytra as slight truncate plates. Abdomen 

 considerably wider than the width across the elytra, the lateral folds hut slightly 

 developed ; aual segment transverse with a central longitudinal sulcus; pygidium 

 small ; forceps straight with the apex falcate, quadrate in section at the base, 

 inner margin with blunt denticules. 



General color deep blackish brown, becoming fuscous on the lower portions of 

 the limbs. Antennae with two joints (12-13) ochraceous.

Two paratypes have been examined of this species, which I take 

 pleasure in dedicating to my friend, Mr. August Busck, who col 

 lected the series. One female from El Yunque, Porto Rico, collec- 

 ted in February by Dr. C. W. Richmond was also examined.
