14 MEMOIRS ON THE COLEOPTERA 



the apex feebly lobed from a vertical viewpoint; sterna coarsely 

 but not densely cribrate, the abdomen much more finely, rather 

 sparsely punctate, more coarsely at the middle of the first segment 

 and with a very dense patch at each side of the second segment. 

 Length 7.7 mm.; width 4.9 mm. Idaho (Cceur d'Alene), Wickham.

lecontei Wickh. 



Prof. Wickham very kindly consented to part with one of the 

 only two known examples of this species, and it now rests in my 

 collection as one of its most valued specimens. 



Tribe SIMPLOCARIINI. 



Comparatively few species, widely distributed over the higher 

 latitudes of the northern hemisphere, are sufficiently isolated in 

 structure to require a separate group or tribe under the above name. 

 They differ widely from the Byrrhini in their shining and sparsely 

 sculptured integuments, less closely retractile legs and peculiar 

 system of elytral striation; from the preceding tribe they differ in 

 possessing true elytral striae. There are two genera as follows: 



Posterior femora in repose resting under and against the hind coxae 

 throughout, the coxae extending to the sides of the body, the epi- 

 pleura narrow anteriorly, gradually disappearing at the usual point 

 opposite the hind coxae; antenna? gradually enlarged and compressed 

 distally through about the last five joints as in the preceding tribe. 

 [Type 5. metallica Sturm]. Palaearctic and nearctic. . . Simplocaria 



Posterior femora in repose resting against both the hind coxae and the 

 obliquely truncated posterior end of the anterior part of the epi- 

 pleura, the latter much wider than in Simplocaria, the hind coxae 

 not attaining the sides of the body; antennae with an abrupt 3-jointed 

 club. [Type S. carpathica Hampe]. Palaearctic *Trinaria 



Trinaria Muls., is represented at present by the type species 

 only; there are some forms of true Simplocaria, such as acuminata 

 Erichs., that imitate it very closely in outward form and especially 

 in the nearly glabrous integuments and sharply acuminate tip 

 of the elytra, but the epipleura and hind coxae, as well apparently 

 as the antenna?, do not depart from the normal type of Simplocaria, 

 where the scutellum throughout is better developed than in Tri- 

 naria; the latter should therefore be considered a distinct genus and 

 not a subgenus of Simplocaria, where it now rests in the latest 

 European catalogue.
