sides, the middle of the disk darker, sometimes in shape of two longi- 

 tudinal bands ; elytra distinctly broader than the thorax, the basal 

 portion raised, the punctnred striae fine, obscured by short pubescence 

 which forms longitudinal short stripes interrupted by darker spaces 

 below the base, before and below the middle, the interstices slightly 

 convex ; underside dark, legs lighter fulvous ; posterior claws 

 piceous. 



Caracas, Colonia Torar, and San Esteban. 



The present species of Physimerus shows very little difference to 

 distinguish it from several other closely allied forms, yet seems to me 

 to be distinct from the hitherto described species, the nearest allied 

 one of which seems to be P. variegatus, Harold, from Colombia ; in 

 this species, however, the eighth interspace of the elytra is described 

 as more strongly raised and as specially characteristic of that insect. 

 In P. simoni there is no trace of any stronger convex interspace, and 

 the punctures are not deeply but finely impressed ; the pubescence 

 varies from golden yellow to grey, and is intermixed with single 

 longer stiff hairs, as is frequently the case in other species of the genus ; 

 the darker places or spots of the elytra are to be found below the 

 basal raised portion, at the middle and below the latter, where a kind 

 of zigzag obsolete transverse baud is formed ; all these spots are in 

 some specimens scarcely visible. 



EUPHENGES(?) SUBCOSTATUS, n. Sp. 



Fulvous, glabrous above ; thorax very finely punctured ; elytra 

 black, finely punctate-striate, the punctuation obsolete below the 

 middle, the sides with an acute short ridge from the shoulder to the 

 middle. 



Var. The lateral margin of the elytra more or less narrowly 

 fulvous. 



Length 1 1— 2 lines. 



Head rather deeply punctured near the eyes ; palpi scarcely 

 widened ; antennae fulvous, the terminal joints strongly incrassate ; 

 the third joint slightly longer than the following ones ; thorax about 

 one half broader than long, glabrous, the sides subangulate before 

 the middle, the surface with a few scarcely visible and irregularly 

 placed punctures, fulvous ; scutellum fulvous ; elytra with a shallow 

 depression below the base, im pubescent, the punctures rather deep 

 at the anterior half, gradually finer and nearly disappearing towards 

 the apex ; underside and legs pale fulvous ; tibise armed with a 

 single spur at the apex ; claws appendiculate. 



San Esteban. 



The incrassate antennae, glabrous upper surface, and the sub- 

 angulate thorax seem to place this species in Euphenges, the fili- 

 form palpi preventing the incorporation in Allochroma, which other- 

 wise seems closely allied. Euphenges seems, moreover, a very doubtful 

 genus and contains two species with filiform and incrassate antennae 

 respectively. In the present insect a distinct acute ridge runs from 

 the shoulders to the middle of the elytra ; these have in some 

 specimens the sutural and lateral margins narrowly fulvous.
