PHYSIMERUS. 91 



the base ; at the sides finely flavo-pubescent and rufo-flavous (more 

 darkly piceous on the line of margination). Scutellum small, tri- 

 angular. Elytra broad, punctate-striate, clothed throughout with a 

 very fine pubescence (which in some parts can only be traced under 

 a high magnifying power) : a broad irregular antemedial band extends 

 transversely from the suture to the margination ; near the suture, 

 and also near the line of margination, it considerably increases in 

 breadth (extending in front at these points nearly to the shoulders 

 and scutellum) ; this band is formed by an ashy-grey pubescence ; 

 the apex also is similarly clothed with pubescence. Antenna; filiform, 

 tolerably long, subdilated towards their apex; joints one to five 

 flavous, six to eleven rufo-flavous. Legs : the anterior flavous ; the 

 posterior rufous, the femora being suffused with piceous. 



From the neighbourhood of Rio Janeiro. Collected by Mr. Squire. 

 In the collection of Mr. Baly.

 thorace elongate, rectangular}, ad basin constricto, ad latera de- 

 presso ; elytris punctato-striatis, ante medium oblique depresses, 

 ad latera irregulariter cinereo lineatis ; antennis longiusculis,

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



Oblong-ovate, subparallel, punctate-striate, impubescent, dark 

 fuscous. Head short, slightly produced; below the base of the 

 antennae is a transverse triangular depression : eyes large, situated 

 at the base of the head, and extending laterally as far as the anterior 

 angle of the thorax ; between the eyes, and immediately above the 

 base of the antennae, is a V-shaped depression, rendered more di- 

 stinct by an ashy-grey pubescence : the surface finely punctate ; at the 

 inner margin of the eyes is a line of fine grey pubescence. Thorax 

 elongate, constricted at the base, rectangular ; the anterior angles 

 depressed ; the sides marginate ; at the base is a broad transverse 

 antemedial depression ; the surface (under a high magnifying power) 

 is obsoletely pubescent, more distinctly at the sides, which are marked 

 (from the base of the head immediately behind the eyes to the 

 posterior angle) with a longitudinal line of ashy-grey pubescence. 

 Scutellum small, triangular, glabrous. Elytra broad, subcylindrical, 

 distinctly punctate-striate ; an antemedial depression extends ob- 

 liquely upwards towards the humeral angles ; throughout the surface 

 are scattered several long and isolated single hairs, which are more
