HOKISTONOTUS. 437 



thickly and somewhat finely punctured, with a few minute punctures intermixed ; antennae slender, 

 extending to some distance beyond the humeri. Prothorax about as long as broad, moderately convex, 

 much wider at the base than at the apex, the sides somewhat obliquely converging from the middle 

 forwards and almost parallel behind ; the hind angles moderately produced ; the surface rather sparsely, 

 minutely punctured, with about an equal number of slightly coarser punctures intermixed ; the base 

 sinuate and bi-incised on either side. Elytra two and two-thirds longer than the prothorax, and a 

 little wider than it at the base, distinctly rounded at the sides, and narrowing from the basal third to 

 the apex, the humeri rounded externally ; deeply punctate-striate, the interstices feebly convex and 

 sparsely punctate. Beneath minutely punctate, with intermixed coarser punctures. Claws rectangularly 

 dilated from the middle to the base. 

 Length 4, breadth 1| millim. 



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



One specimen. This inconspicuous species greatly resembles H. hcemorrhoidalis, 

 but may be at once known from it by the form of the claws ; it is also smaller and less 

 elongate, the antennae are much shorter and pitchy-black, and the finer intermixed 

 punctures on the thorax are less numerous.

 Ilab. Mexico 1 . 



We have not received a specimen of this very distinct species, the abraded ( s ) type 

 of which has been communicated by Dr. Candeze. The punctuation of the head and 

 thorax is dense, the conspicuous larger punctures being closely placed towards the 

 apex of the thorax and on the head. The elytra have rows of coarse punctures placed 

 in very shallow stria?, the interstices being flat and thickly punctate. The thorax is 

 much broader than long, with the base strongly sinuate and bi-incised on either side. 



17. Horistonotus fasciatns. (Tab. XIX. fig. 17, <s .) 



Short, convex, sbining, thickly pubescent ; rufo-testaceous, tbe elytra with a rather broad median fascia, 

 extending down the suture to near the apex, black or piceous ; the antennas and legs testaceous. Head 

 closoly, somewhat coarsely punctate ; antennas slender, half the length of the body in the male, a little 

 shorter in the female. Prothorax much broader than long, slightly wider at the base than at the apex, 

 rounded at the sides, obliquely narrowed behind ; the hind angles moderately produced and rather obtuse ; 

 the surface closely, finely, uniformly punctate ; the base sinuate and bi-incised on either side. Elytra 

 oval about two and one-half times longer than the prothorax, and of the same width at the base ; deeply 

 punctate-striate, the interstices moderately convex throughout, and minutely punctured. Beneath closely, 

 finely, uniformly punctate. Claws rectangularly dilated from the middle to the base. 



Var. The elytral markings obliterated. 



Length 4^-4|, breadth If millim. ( tf $ •) 



Ilab. Mexico, Acapulco (Edge). 



Ten specimens. Allied to H. unitinctus, Cand., from Brazil, but broader, the thorax 

 and elytra more rounded at the sides, the thorax more narrowed behind. As in 

 many other species of the genus, the base of the thorax has two deep notches on 

 either side near the inner limit of the hind angles.
