78 PHYSIMERITS. 



fine and indistinct ashy pubescence, fuscous. Head short, transverse, 

 and (when viewed laterally) very slightly produced; the eyes are 

 large, prominent, and distant ; between the eyes is a distinct trans- 

 verse groove, inclining obliquely upwards in the direction of the 

 upper and inner margins of the eyes, and connected by a medial 

 horizontal fovea with the insertion of the antenna? ; surface of the 

 head thickly and coarsely punctured or granulated, flavo-rufous. 

 Thorax quadrate (with the anterior and posterior angles distinct and 

 subacute) ; sides marginate, slightly constricted towards the base, 

 subpubescent, flavo-rufous. Scutellum triangular, fuscous. Elytra 

 indistinctly but broadly punctate-striate, obsoletely pubescent; a 

 slight antemedial depression gives an appearance of prominence to 

 the shoulders ; fuscous. Antennas filiform, somewhat elongate ; the 

 first joint broad, and dilated near the apex ; the second short, ovate ; 

 the third, fourth, and fifth of nearly equal length, and thinner than 

 the basal or apical joints ; the first, second, and third flavous, the 

 rest fuscous. Legs slightly pubescent, flavous throughout. 



Corcovado. Rio de Janeiro. I know only of one example of this 

 species, in the cabinet of Mr. Fry, 



10. Physimerus inornatus. 



P. oblongo-ovatus, subconvexus, parallelus, niger ; capite brevi, 

 punctato, rufo ; thorace transverso, ad basin leviter constricto 

 etiamque late depresso, punctato, ad basin flavo-pubescenti ; elytris 

 parallelis, punctato-striatis, subtiliter pubescentibus, nigris ; an-

Long. corp. 2 lin., lat. f lin. 



Oblong-ovate, parallel, subconvex, black, pubescent. Head short, 

 almost vertical ; eyes large, prominent, extending laterally as far as 

 the margin of the thorax ; between the eyes and above the insertion 

 of the antennae is an obscure obliquely- transverse depression ; surface 

 finely punctate, rufous. Thorax transverse (almost quadrate), slightly 

 constricted at the base ; the anterior angles are depressed, the sides 

 slightly marginate ; at the base is a broad transverse depression ; the 

 surface is very finely punctate, at the base flavo -pubescent, rufous. 

 Scutellum oblong, triangular, black. Elytra parallel, coarsely punctate- 

 striate, clothed throughout with very fine ashy pubescence, black. 

 Antennae filiform, black. Legs flavous throughout; the globular in- 

 flation of the posterior claw bright fulvous. 



This species differs from P. minutus not only in its larger size, but 

 in the form and clothing of the thorax ; it is less constricted at the
