elongated, slightly yellowish-white scales, longer and more hair-like 

 on the head and prothorax, and leaving slightly past the median 

 part of the elytra three small, denuded, elongated spots set sub- 

 transversely on each side ; the clypeus is aculeate laterally and 

 deeply emarginate in front, being thus almost hexagonal ; the pro- 

 thorax is plainly scrobiculate, and has no median longitudinal groove, 

 but the supra-lateral elongate patch on each side of the posterior 

 part is very plain ; scutellum somewhat deeply punctate ; elytra 

 non-costulate ; propygidium clothed with very fine, slightly squami- 

 form, appressed hairs, but having a band of scales along the posterior 

 margin ; pygidium, abdomen, and legs clothed with whitish scales, 

 pectus densely hairy ; anterior tibiae uni-dentate ; legs, palpi, and 

 antennas rufescent-brown. 



Length 13 mm. ; width 7 mm.

PSILONYCHUS BAEKERI, n. Spec. 



Male : Narrower and more cylindrical than the two preceding 

 species, clothed like P. eckloni with whitish or slightly flavescent 

 scales which form on each elytron four uninterrupted bands sepa- 

 rated by three narrow denuded lines ; the hairs along the margins 

 of the prothorax, the base especially, are plainly flavous ; the clypeus 

 is more sharply emarginate in the centre and narrower than in 

 P. eckloni; the prothorax has a faint median longitudinal impres- 

 sion in the posterior part, and the lateral denuded patch is narrow 

 but distinct ; scutellum impunctate ; the elytra are not costulate, 

 but the denuded lines seem to be slightly raised behind ; pygidial 

 part and under side as in the preceding species ; anterior tibiae 

 uni-dentate. 



Length 11|-12 mm. ; width 5J-5J mm.

Male : Bronze-green, with -the elytra and legs often rufescent, 

 clothed on the upper side with white lanceolate scales, disposed on 

 the elytra in four broad bands, divided by a narrow, smooth line, 

 and having a broad, sub-quadrate, denuded patch under the 

 scutellum, and a narrower but longer transverse band slightly past
