base, and more distinctly pubescent : from otber species it will be 

 readily distinguished by the distinct colour of its elytra. 



From the district of the Amazon. In the collection of Mr. Bates. 



11. Physimerus minutus. 



P. oblongus, ovalis, depressus, parallelus, niger ; capite brevi, im- 

 punctato, rufo ; thorace brevi, transverso, ad basin constrieto et 

 depresso ; elytris subcylindricis, punctato-striatis, pallide pubes- 

 centibus ; antennis filiformibus, nigris ; pedibus jiavis, posticorum 

 femorum apicibus fuscis. 



Long. corp. If lin., lat. f lin. 



Oblong, oval, depressed, parallel, black. Head short, hardly pro- 

 duced; eyes large, prominent, extending beyond the line of the thorax; 

 between the eyes and above the base of the antennse is a depression 

 in the form of the letter T ; surface impunctate, rufous. Thorax 

 small, transverse, considerably constricted at the base ; the anterior 

 angles much depressed, and concealed below the outer margin of the 

 eyes ; the sides are slightly marginate ; at the base is a broad trans- 

 verse depression ; the surface is flavo-pubescent and rufous. Scutellum 

 triangular, black. Elytra broader than the thorax, subelongated, 

 parallel, coarsely punctate-striate, black, clothed throughout with fine 

 ashy pubescence. Antenna filiform, black. Legs flavous throughout ; 

 the tips of the posterior femora fuscous. 



This species differs from P. luteicollis in its black elytra, by its 

 more transverse thorax, and by its smaller size ; from P. inornatus 

 by its impunctate head, by the fineness, as well as ashy (instead of 

 flavous) pubescence on the elytra, and also by its smaller size. 



From the Amazon district. 



12. Physimerus obscurus. 



P. oblongo-ovatus, parallelus, subpubescens ; capite brevi, elongatido, 

 inter oculos longitudinaliter foveolato, gramdato, rufo ; thorace 

 elongato, subcylindrico, angulis anterioribus subacutis, ad latera 

 marginato, ad basin depresso et subcoarctato, granulato, rufo- 

 ferrugineo ; elytris punctis crebris in striis ordinatis, transverse 

 complanatis, nigris ; antennis fil if ormibus, art. 1-4 ferrugineis, 

 eastern fuscis ; pedibus fuscis, tarsis tibiisque posticis ferrugineis. 



Long. corp. 1^ lin., lat. g-f lin. 



Oblong-ovate, parallel, subpubescent, black. Head short, slightly 

 elongated and compressed in front ; eyes large and prominent ; im- 

 mediately above the base of the antennse is a short abrupt longitudinal
