178 ATYPHT78. 



diately above the base of the antennae, are two minute subprominent 

 tubercles, which are more apparent by being each of them sur- 

 rounded by a circular fovea ; eyes large and prominent, extending 

 laterally nearly as far as the angles of the thorax ; the surface (when 

 viewed under a high magnifying power) subpubescent and finely 

 granulated, fulvo-flavous. Thorax transverse, slightly broader than 

 the head, rectangular ; the anterior angles subacute and depressed ; 

 the sides marginate ; at the base is a broad transverse depression, ex- 

 tending upwards in a subcircular form towards the anterior angles ; 

 the surface finely testaceo-pubescent, fulvous. Scutellum triangular. 

 Elytra parallel, robust, deeply and broadly punctate-striate ; the 

 colour fulvo-ferrugineous : parallel to the suture are two well-defined 

 bands of fuscous-black, which extend from the shoulders to the apex ; 

 these bands have the breadth of two striae, and are at the distance 

 from the suture of four striae ; the sutural line itself also is obsoletely 

 fuscous. Antennae filiform, fuscous. Legs fulvous, with the base of 

 the posterior femora and the anterior tarsi (with part of the anterior 

 tibiae) fuscous. 



Taken in the neighbourhood of Rio Janeiro, by the late Mr. Squire, 

 December 1859. 



4. Atyphus furcipes. 



A. ovatus, robustus, cyaneus, nitidus; capite brevi, transverse, ad 

 basin antennarum T foveolato, impunctato ; thorace lato, trans- 

 verso, ad basin depresso ; elytris robustis, punctato-striatis ; an- 

 tennis filiformibus, nigris ; pedibus nigro-cyaneis. 



Long. corp. 3| lin., lat. 2 lin. 



Ovate, robust, of a bright dark-blue colour throughout. Head 

 short, transverse, slightly produced in front ; immediately above the 

 base of the antennae is a distinct fovea in the form of the letter T ; 

 the surface is impunctate. Thorax broader than the head, trans- 

 verse ; the anterior angles subprominent and considerably depressed ; 

 sides marginate ; at the base is a broad and shallow depression of a 

 semicircular form (extending upwards near the margins in the direc- 

 tion of the anterior angles) ; the surface is impunctate and glabrous. 

 Scutellum triangular and impunctate '. Elytra robust, broader than 

 the thorax, deeply punctate-striate; an antemedial transverse de- 

 pression (which is broad and shallow) gives an appearance of 

 prominence to the humeral angles. Antennae filiform, tolerably 

 robust, black. Legs of a dark-blue colour, the tarsi being suffused 

 with fuscous.
