Genera and Species of Coleoptera. 51 



nutely punctured ; disc of the prothorax slightly concave, with two 

 large foveas at the base ; scutelhun subquadrate ; elytra punctured, 

 principally in rows of about six on each ; eyes dark brown. Length 

 2± lines. 



Euryptts [Tenebrionidae ?]. 



Kirby, Trans. Linn. Soc. vol. xii. p. 389. 



Eurypus cupripennis. 

 E. subangustus, subtilissime punctatus, caeruleo-chalybeatus, nitidus ; ely- 



tris cupreis. 

 Hab. Brazil (Para). 



Head rounded, pitchy, finely punctured ; eyes and antennae black ; 

 prothorax narrower than the head or elytra, steel-blue, finely punc- 

 tured, a deep transverse impression posteriorly ; elytra elongate, gra- 

 dually widening behind, rich coppery-red, minutely punctured ; legs 

 small, pitchy ; body beneath steel-blue. Length 5 lines. 



Stilpnonotus eurypiformis (named, but not described, by Mr. G. R. 

 Gray in the English edition of the ' Regne Animal ') appears to me 

 to be referable to Mr. Kirby's Eurypus, a genus not alluded to by 

 M. Lacordaire in his great work. Mr. Kirby's species, E. rubens, 

 from the figure, seems to be a much broader insect than the present, 

 which it is not impossible may be identical with Olivier's Tenebrio 

 nitens. The pronotum is confounded with the parapleurae, and the 

 anterior coxa? are contiguous and greatly exserted, two characters 

 which do not accord well with the Tenebrionidae : the possession of 

 antennary orbits forbids its association with Lagriidae. In habit it 

 is slightly assimilated to Camaria. 



(Edemutes [Helopidae]. 



Head transversely subquadrate ; epistome large, deeply inserted in front. 

 Labrum short, transverse, broadly emarginate. Eyes rather broad, sub- 

 lunate. Last joint of the labial palpi securiform, of the maxillary nar- 

 rowly triangular. Antennae very short, clavate, 11-jointed, the first 

 joint nearly concealed by the antennary orbit, the second short, third 

 longest, the rest gradually increasing in breadth to the seventh, which, 

 with the remainder, forms a sort of club. Prothorax transverse, slightly 

 convex, carinated at its sides, the base closely applied to the elytra. 

 Scutellum small. Elytra ovate, very convex. Legs rather short ; an- 

 terior femora strongly toothed ; tibiae slightly curved ; tarsi very short, 

 the last joint longer than the rest together. Prosternum received in a 

 notch of the mesosternum. 



Very near Sphcerotus, from which it differs in the antennae and 

 legs, especially in the profemora toothed as in Enoplopus, and in
