Hab. Ega, Upper Amazons. Collected by Mr. Bates, to 

 whom I am indebted for a specimen. 



Elongate, subdepressed, shining red ; antennae 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 ; 

 antennae rigid, very acute, shining black, inner surface of basal 

 joints rufous. Thorax one-half broader than long at the base j 

 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 

 diatantly serrate, posterior angles armed with a stout acute spine, 

 which runs almost directly backwards; apex obtuse, its outer 

 edge serrate ; above subdepressed along the sulure ; each ely- 

 tron with three elevated costic, 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 tlie antenna; from the third upwards 

 intimately 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
