240 UYPOLAMPSIS. 



head; the surface deeply granulated. Thorax transverse (almost 

 quadrate) ; the anterior angles depressed ; the sides parallel and mar- 

 ginate ; the surface equate, and granulated, not so deeply as the head. 

 Scutellum triangular, impunctate. Elytra robust, parallel, deeply 

 and regularly punctate-striate, impubescent, except obsoletcly at the 

 apex. Antennae robust, subdilated towards the apex, black, the two 

 apical joints being testaceous. Leys flavous; the anterior tarsi and 

 apex of the tibia? suffused with fuscous, and the base of the posterior 

 femora piceous. 



This very distinct species may be separated from all others by its 

 uniformly pitchy-black colour, its impubescence, and the arrange- 

 ment of markings on the antenna?. 



H. Murraii occurs not unfrequently in the suburbs of Rio Janeiro, 

 where it was taken by Mr. Gray and myself, and also, in some 

 abundance, by Mr. Fry during his visit to the Brazils in the spring 

 of this year. Mr. Fry remarks respecting this species, " it con- 

 gregates on the tops of some small shrub, one or two individuals 

 frequently on each leaf; they arc very difficult to secure, as they 

 leap off with great force and activity on being approached." 



10. Hypolampsis signaticornis. 



H. oblongo-ovata, parallela, suhcylivdrica, subpiliter pubescens, 

 nigra ; capite brevi, ad basin granulato ; thorace transverso, ad 

 basin constricto et transverse depresso, punctata ; elytris punc- 

 tato-striatis, ad medium oblique depressis, ad basin flavo-sub- 

 pubescentibus ; antennis incrassatis, ad apicem rufo-fuscis, arti- 

 cidis 3, 4, et 8-11 testaceis ; pedibus flavis. 



Long. corp. 1^ lin., lat. ■§ lin. 



Oblong-ovate, parallel, subcylindrical, very finely pubescent, black. 

 Head short, transverse, depressed at right angles to the plane of the 

 thorax, produced in front ; mandibles flavous, with the apex fuscous ; 

 above the labrum is a transversely triangular depression ; eyes large, 

 prominent, situated at the base of the head ; the surface at the base 

 (above the antenna?) is thickly granulated. Thorax transverse (the 

 length being nearly equal to the breadth), constricted towards the 

 base ; the anterior angles arc depressed ; the sides are marginate ; 

 at the base is a broad and shallow transverse depression ; the surface 

 throughout is thickly and coarsely punctate. Scutellum minute. 

 Elytra somewhat broader than the thorax, parallel, coarsely punc- 

 tate-striate throughout, and at the apex clothed sparingly with ob- 

 solete flavous pubescence ; a shallow transverse antemedial depres- 

 sion extends obliquely upwards towards the humeral angles, giving
