Elongate, conico-cylindrie, shining, black, the sides of the elytra broadly rufescent (leaving an attenuate black 

 sutural stripe), the antennae, tibiae, and tarsi ferruginous. Head sparsely punctate, transversely depressed 

 and feebly foveate between the eyes ; rostrum very short, stout, closely punctate. Prothorax broader than 

 long, suboval, constricted in front, closely, rather coarsely punctate. Elytra much broader than the

prothorax, moderately long, gradually widened to beyond the middle and somewhat produced at the apex ; 

 with rows of moderately coarse punctures placed along narrow shallow striae, the punctures becoming 





smaller and more scattered towards the sides, the interstices broad, almost flat, and finely uniseriate- 



punctate. Beneath sparsely, finely punctate. 

 Var. The elytra indeterminately rufescent towards the tip only. 

 Length 2J-3f, breadth 1^-1 1 millim.

Hab. Mexico, Motzorongo (Flohr) ; Guatemala, Cerro Zunil, Las Mercedes. 

 Capetillo, Duenas (Champion). 



Fourteen specimens from the Pacific slope of Guatemala, scarcely varying in colour, 

 and two others, treated as a dark variety, from Motzorongo in Vera Cruz. A com- 

 paratively large, posteriorly widened form, with the elytra very broadly rufescent at 

 the sides and the punctures of the outer series rather fine and somewhat scattered.

Elongate, conico-cylindrie, shining, black, the antennae and tarsi ferruginous. Head sparsely punctate, 

 transversely depressed and feebly foveate between the eyes ; rostrum very short, stout, closely punctate. 

 Prothorax broader than long, suboval, constricted in front, closely, coarsely punctate. Elytra very 

 gradually widened or subparallel in their basal half, conjointly rounded and scarcely produced at the 

 apex ; coarsely seriate-punctate, the punctures closely placed along shallow striae, the interstices rather 

 broad, feebly convex, and conspicuously uniseriate-punctate. 



Length 2§-3§, breadth 1-1£ millim. 



Hab. Mexico, Paso del Macho, Cordova, Jalapa (Hoge) ; British Honduras (Blanca- 

 neaux); Guatemala, San Geronimo {Champion). 



Nine specimens. Perhaps a dark form of P. limbatum, with the prothorax and 

 elytra more coarsely punctured. The two examples from San Geronimo are taken as 

 the types.

 basal half, the apices somewhat produced, conjointly rounded, and narrowly margined ; rather coarsely 

 seriate-punctate, the punctures placed in shallow striae, the interstices feebly convex, obsoletely and 



irregularly uniseriate-punctate. Beneath closely punctate ; first ventral segment broadly depressed down
