larly convex without any callosities near the apex. Metasteinuiii sliuit. 

 First and second abdominal segments df ahout equal length, the third and 

 fourth rather shortei', hut together murh linger tlian either of the preceding, 

 the fifth segment slightly longer than the first. Legs moderately robust ; 

 femora somewhat clavate, tiliia^ unarmed. (Type, A. alticola.) 



This genus chiefly differs from Lidroderes in the form of the antennal 

 scrobes, the structure of the abdominal segments, and the feebly developed 

 ocidar lobes.

Hah. Chimborazo (12-15,800 feet). 



Elongate-ovate, much narrower in front than behind, latcliy black, some- 

 what shining, modei'ately densely covered with small ebingate dirty yellow 

 scales and hue pubescence. Head ratlier coUAex, hnely and very closely 

 punctui'ed ; rostrum robust, narrower lieliind than in front, as closely

 red. Prothorax broadly transverse, slightly narrower in front than at the 

 base, closely but rather hnely and obsoletely punctured, tlie disc more finely 

 and sparingly pulDescent than the margins ; no apparent median line ; sides 

 regularly ai'cuate. Scutellum hnely punctured. Elytra al)OUt two and a 

 half times as long as the head and pi'othorax together, moderately strongly 

 striate -punctate, the interstices rather broad and very slightly raised ; 

 humeral angles not prominent ; siiles arcuately rounded to the apex. Under- 

 side rather sparingly covered with long dirty yellow puliescence, very 

 sparingly and olisoletely jiunctured. Legs pitchy and finely iiul)escent. 

 Length, 6^-7i mm. 



The scales and pubescence of this and the Ibllowing species are very 

 easily removed ; some of tlie specimens collected by Mr. Whymper are some- 

 what rubbed, ami thus have a sj^eckled appearance as if the scales, etc., were 

 arranged in small patches.

Very closely allied to A. alticola ; slightl}' longer and narrower ; the head 

 more chjsely punctured ; prothorax somewhat narrower and decidedly longer, 

 hnely but more distinctly and closely punctiu'ed ; scutellum small, covered 

 with fine punctures and pubescence ; elytra rather longer and the sides 

 more }iarallel, the pimctures slightly more distinct. Underside ratlier more
