 femorum, capite pronotoque interdum infuscatis, tenuiter griseo-pubescens 

 aut ex parte sub nudum, tarsis supra densius griseis. Caput et pronotum

 Scutellum rotundatum. Elytra subnitida, discrete punctata punctis apicem 

 versus multo minoribus, pilis adpressis, brevibus, griseis vestita, apice singu-

Two specimens, Upolu : Apia, 18.iv.1925 (Buxton and Hopkins) ; 

 Malololelei, 13.ix.1923 (Swezey and Wilder). Three specimens, Tutuila : 

 Pago Pago, 30.ix.1923 (Steffany) ; 1200 ft., 21.vii.1918 (Kellers). 



The specimens from Tutuila have a somewhat narrower and more finely 

 sculptured prothorax 



Allied to C. olidum Fairm., but differing from that and other known species 

 in the sculpture of the prothorax.

Two males and two females, Upolu : Apia, i.1925, Malololelei, 2000 ft., 

 14-30.vi.1924. Two males, Tutuila: Pago Pago, 24.ix.1923 (Swezey and 

 Wilder). 



Also one male, Tonga : Vavau, Neiafu, 5.viii.l925 (G. H. E. Hopkins). 

 The type of this species was obtained in Tahiti. Specimens from that 

 island are paler, with the sides of the pronotum only slightly darkened in the
