Hab. Ega, Upper Amazons. Collected by Mr. Bates, to 
whom I am indebted for a specimen. 
Elongate, subdepressed, shining red ; antenne and eyes black ; 
elytra costate, the anterior two-thirds of the suture, the outer 
border, a square spot in front, an oblique band across the middle, 
abbreviated at the outer margin, and the apex black. Head sub- 
rugose, forehead deeply impressed with a longitudinal fossa ; 
antenne rigid, very acute, shining black, inner surface of basal 
joints rufous. Thorax one-half broader than long at the base ; 
sides slightly rounded behind, narrowed and sinuate in front ; 
above cylindrical, depressed and excavated at the middle of the 
base ; surface coarsely and deeply punctured, punctures crowded 
on the sides; the medial line with a deep longitudinal groove. 
Scutellum smooth, shining. Elytra deeply punctate-striate, 
much broader than the thorax, subelongate ; sides nearly parallel, 
scarcely broader behind, narrowly margined, margin slightly 
dilated towards the posterior angles, its outer edge coarsely and 
distantly serrate, posterior angles armed with a stout acute spine, 
which runs almost directly backwards; apex obtuse, its outer 
edge serrate ; above subdepressed along the suture; each ely- 
tron with three elevated coste, which occupy the alternate inter- 
spaces between the rows of punctures. Beneath shining rufous ; 
mouth and tarsi piceous.

Hab. Paramaribo, Surinam. 
Very similar in form to A. generosa ; the spines, however, at 
the hinder angles of the elytra are produced more directly out- 
wards than in that insect ; the thorax is also somewhat narrower 
and more cylindrical; vertex impressed with a longitudinal 
- groove; all the joints of the antennz from the third upwards 
itimately connected, without the slightest trace of articulations, 
their apex very acute. Thorax one-half broader than long, 
sides straight and parallel at the base, rounded and narrowed in
