ON THE GENUS CEROBATES. 219 



eyes almost angulate, never regularly rounded, antennae 

 with the 9^^ and lO^^i joints oval, the apical one short, 

 ovato-conical ; prothorax smooth , elytra along the sutural 

 interstice tristriate , the S^'i dorsal stria in the typical form 

 prolonged down to the tip ; sides of the elytra distinctly 

 striate. Colour ferruginous brown or chestnut, the sutural 

 interstice darker. Sometimes the 3rd dorsal stria is narrower 

 or obsolete behind the middle of the elytra. A smaller 

 race [Trachelizus pumilus Dej., pygmaeus olim) is often pale 

 brick coloured , has the S^^ stria interrupted or narrower 

 behind the middle, and the sides of the elytra less evidently 

 striate but never smooth and shining. The passages between 

 the above mentioned forms are almost imperceptible among 

 a great number of specimens and render a satisfactory 

 separation of them very difficult. — Length 4^/3 — 872 ^i\-h 

 — Very common.

Hab. Sangi Islands. 



One specimen in Walter Rothschild's Museum at Tring. 



This species is without any doubt the representative of 

 C. tristriatus in the Sangi Islands , and differs only from 

 that species by having the rostrum slender, the prorostrum 

 a little longer, the sides of the elytra smooth and shining. 



7. C. angustipennis Senna.
