black clypeus and basal joint of the antennae are probably con- 

 stant characters. 



Tropidosteptes tricolor n. sp. 



Allied to amcenus var. scutellatus but larger and still 

 broader; black, head and abdomen rufous, antennae, legs and 

 cuneus whitish. Length 6 mm. 



In its structural characters this species differs from amoenus in hav- 

 ing the vertex and front broader, the pronotum longer and more narrowed 

 anteriorly with a deeper and more uniform puncturation, the elytra more 

 closely and finely punctured and the whole surface, while polished, closely 

 and quite long pale pubescent. Aside from this it has all the characters of 

 Tropidosteptes to which genus it must be referred. 



Color pieeous-blaek. Antenna? whitish with the apex of the second joint 

 broadly infuseated. Head rufous with the eyes dark castaneous and the 

 clypeus black. Collum of the pronotum concolorous touched with rufous 

 at the middle; cuneus whitish pellucid; membrane deep fuscous. Eostrum, 

 legs coxae and trochanters almost white; tarsal claws black; metapleura 

 white between the intermediate and hind coxre. Abdomen rufous, obscured 

 on the genital segment. 



Described from one female specimen taken at Riverton, N. 

 J., June 7th, 1909, by Mr. C. W. Johnson. The black color 

 with pale cuneus gives this species somewhat the aspect of 

 geminus but its red head and abdomen, pubescent surface and 

 other structural characters will at once distinguish it. 



Tropidosteptes geminus Say. 



This species, which was described as a Capsus and well 

 characterized by Say, was taken by me at Colden, near Buffalo, 

 N. Y. , on June 7th. 1908. I cannot find that it has been recog- 

 nized by any of our later entomologists. It can readily be 

 distinguished by its polished piceous-black color with whitish 

 legs, basal antennal joint, and base of cuneus. The base and 

 sides of the vertex are yellowish in my specimens. 



Tropidosteptes imperialis n. sp. 



Form and size of cardinalis; elytra mostly deep blue-black ; 

 head, pronotum, scutellum and cuneus pale or sanguineous. 

 Length 6 mm. 



Head formed as in cardinalis; polished, impunctate, the clypeus a little 

 less incurved at apex; base of the vertex slenderly but distinctly carinate. 

 Pronotum more finely punctured than in cardinalis, the anterior margin be- 

 fore the eallousities impunctate, polished. Scutellum scarcely punctured, 

 minutely transversely wrinkled. Elytra minutely and obscurely punctured.
