resemblance to the Palaearctic Colotes trinotatus, Er. The 

 N.-American A. rvfiventris, Horn, again, is not unUke the 

 present species, except that it is very much larger.

(J. Anterior tarsi with the prolonged upper portion of joint 2 

 about reaching the apex of 3 ; last dorsal segment of the abdomen 

 with a very deep fovea extending down the apical half. 



$. Last dorsal segment arcuate-emarginate in the middle at the 

 tip. 



Hab. Panama, Taboga Island. 



This species is alHed to A. albolimbatus (= limbatns, 

 Gorh.), differing from it in the shorter, opaque elytra 

 (leaving two or three segments of the abdomen exposed), 

 the non-metalhc dorsal vitta of the latter, and the peculiar 

 (^-characters. The elytra and the exposed dorsal surface 

 of the abdomen are conspicuously nigro-setose. The 

 colour of the head and prothorax is variable. The antennae 

 are short in both sexes. A female from the same locahty, 

 evidently belonging to A. tabogensis, has the prothoracic 

 margins only pale, and the elytra more elongate, with the 

 dorsal stripe (which is narrowed or evanescent anteriorly 

 in the types) broad throughout, and extending inward 

 to the suture at the base. 



27. Attains scutellaris.

(J. Anterior tarsi with the prolonged upper portion of joint 2 

 stout, reaching the apex of 3. 



Hab. Mexico; Guatemala. 



Represented in the " Biologia " collection by a pair 

 from Guatemala and a female from Mexico. Very hke 

 A. anthobioides, but with a large, aeneo-piceous, elongate- 

 triangular, common scutellar patch reaching to beyond 

 the middle of the elytra; the prothorax less transverse, 

 and with the dark portion brassy (the anterior margin 

 testaceous in ^); the elytra more shining, and densely, 

 minutely punctate. A. scutellaris is related to the N.- 

 American A. scincetus, Lee.
