punctate, the disc slightly depressed down the middle posteriorly. Scutellum large, flat, rounded, finely 

 alutaceous, impunctate. Elytra broadly flattened, much wider than the prothorax, subparallel in their 

 basal half and rapidly narrowing thence to the apex, the apices conjointly rounded ; shallowly crenato- 

 sulcate, the punctures not very coarse and somewhat distant one from another, the interstices feebly 

 transversely rugulose, almost flat and broader than the sulci on the disc, convex at the sides and apex. 

 Beneath sparsely, finely punctate; metasternum transversely depressed posteriorly and with a 

 median groove; ventral segments 1 and 2 broadly depressed down the middle ; tarsal claws small. 





Length 3f , breadth 1^ millim. ( d .) 



Hab. Guatemala, Purula in Vera Paz (Champion).

One male. The elytra in this insect are coloured very much as in Catolethrus 

 longidus. It has a rather long, cylindrical rostrum, an almost unimpressed prothorax, 

 a large scutellum, small tarsal claws, &c., and may have to be removed from the genus 

 Cos somes.

Found in numbers in Guatemala, in the vicinity of the Volcan de Fuearo. This 



b 



species has the rostrum formed much as in C. hubbardi, Schwarz, and C. lotus, Boh., $ , 



+ 



differing from the former in its less coarsely sculptured surface, and from the latter in 

 its much smaller size, the very shallow basal fovea of the prothorax, &c. Two of the 

 males from Zapote are larger and more robust than the rest and have the head very 



■ 



coarsely punctured between the eyes. C. puncticollis, Boh. (nee Woll.) (antea, p. 46), 



■ 



may be an allied form. C. hubbardi lives in the rotting trunks of the giant Cactus 



■ 



(Cereus giganteus) in Arizona*.
