tures. The prostemum is elongate, triangular, less narrow 

 than in N. fasciculare. The metasternum is only visibly 

 punctured in the middle when examined with a powerful 

 magnifier, but the sides are very strongly punctured, as 

 are also the legs (especially the femora). The abdomen 

 is not visibly punctured. 



The mentum has two longitudinal deep grooves, which 

 make it appear divided into three parts ; this gives it a 

 curious appearance, but I think it is not of generic im- 

 portance.

Byrrhid^ v. Cryptocephalid^. 

 Inclica soUda, Walker. 



The type of this insect has just come under my notice. 

 It does not belong to the Byrrhidcs as placed by Walker, 

 but is one of the Cryptocephalida, close to (if not congeneric 

 with) Monachus. Motschulsky (Bull. Mosc. 1866, i. p. 

 412) describes five species of Monachus from Ceylon ; and, 

 judging from his descriptions, I think it probable that all 

 his so-called species are only colour varieties of one, and 

 that Inclica solida, W., is only another variety. 



It may be convenient to retain the name Inclica as 

 distinct from the American Monachus, as a close exami- 

 nation is very likely to bring to light generic differences 

 in insects from opposite quarters of the globe. 



Inclica solida, W., 1859 = ? Monachus Jlaveolus, hasa- 

 lis, suturalis, nigrolimbatus, and acutangulus. Mots. 1866. 



PSEPHENIDiE. 



Tychepsephus, gen. nov. 



General form that of Psephenus, but convex. Head 

 formed nearly as in that genus, but less free, owing to the 

 prominent angles of the thorax ; the mouth is almost 

 entirely hidden by the prostemum being produced ante- 

 riorly; clypeus very narrow, and rounded in front. 

 Thorax transverse, narrowed in front, fr'ont margin 

 slightly lobed in the middle, the anterior angles some- 

 what prominent, base broadly bisinuate. Scutellum 

 cordiform. Elytra ample, a little longer than broad, 

 convex, a little broader than the thorax at the base, but 

 much wider posteriorly, and then gradually narrowed to 

 - the apex. Prostemum very slightly produced posteriorly
