50 RUINOTMETUS. 



obsolete depression above ; the surface is finely punctate, and at the 

 apex glabrous ; eyes tolerably large, globose, situated at some little 

 distance from the base of the head. Thorax elongate (almost qua- 

 drate), the anterior angles much depressed and coarctate ; the sides 

 parallel and marginate ; at the base is a broad transverse depression ; 

 the surface throughout is finely punctate. Scutellum triangular, im- 

 punctate. Elytra somewhat broader than the thorax, parallel, sub- 

 depressed, punctate-striate (the punctures being deep, and the stria? 

 (comparatively) obsolete) ; an antemedial depression extends ob- 

 liquely upwards towards the humeral angles, giving a somewhat 

 turgid appearance to the surface near the scutellum. Antenna'. 

 robust and filiform. Legs tolerably robust, the globular inflation of 

 the posterior claw being rufo-flavous. 



Brazil. 



16. Rhinotmetus humilis. 



R. ohlonqo-ovatus, subcylindricus, fulvus, Iwido-pubescens ; capite 

 producto, punctulato, rufo-fulvo ; thorace elongate, antice rotun- 

 da to (etiamque ad latera), depresso, punctata ; elytris subelongatis, 

 punctis minutis velut in striis ordinatis, lurido-pubescentibus ; 

 antennis Jilif omnibus, sat robustis, fulvis ; pedibus fulvis. 



Long. corp. 2| lin., lat. 1^ lin. 



Oblong-ovate, somewhat depressed, fulvous, covered (throughout?) 

 with a lurid squamose pubescence. Read elongated in front, de- 

 pressed, pubescent ; eyes large, prominent. Thorax elongated, sides 

 slightly marginate, contracted towards the head ; the anterior angles 

 rounded ; surface plane, anteriorly depressed, finely punctate ; clothed 

 throughout (as is the head) with a close, squamose, lurid pubescence. 

 Scutellum almost obsolete. Elytra subelongate, subcylindrical, with 

 shallow punctures arranged in the form of stria? ; covered (probably 

 throughout) with close, squamose, lurid pubescence, which partially 

 conceals an under- clothing of bright fulvous pubescence. Antenna; 

 filiform, short, fulvous. Legs fulvous. 



The specimen from which this description is drawn is somewhat 

 old and rubbed. Perfect specimens, I doubt not, will be found to 

 be clothed throughout with a flavous pubescence, which is covered 

 more or less with a fuscous and squamose pubescence. 



From the neighbourhood of Rio Janeiro. A single specimen, in 

 the collection of Mr. Miers. 



17. Rhinotmetus pallipes.
