Colour variable, bright cyaneous blue or purple or blackish ; 

 labrum black or yellow ; antennas reaching to about the middle of the 

 pronotnm, only slightly thickened towards apex, varying in colour, 

 palpi dark or rufescent ; pronotum elongate, longer than the head 

 and labrum together, with a strong contraction just before base, 

 which is sinuate, inflated in front of the contraction and gradually 

 narrowed to the pronotal collum, which is somewhat abrupt, 

 inflated portion more rounded in some specimens than in others, 

 collum short, reflexed anteriorly, disc with 

 fine transverse wrinkles ; elytra twice as 

 broad as pronotum, with the humeral angles 

 blunt but well-marked, subparallel-sided, 

 strongly punctured towards the base, the 

 punctures becoming somewhat rugose but 

 not plicate about middle, and being smaller 

 and more closely set behind ; legs rufous, 

 with the tibia?, tarsi, and coxa3 dark ; 

 episterna of metasternum finely punctured ; 

 abdomen almost smooth, the apical portion 

 more or less rufescent. 

 Length 18-27 millim. 

 The following localities have been given 

 for this species : — Madras : Mysore (?) ; 

 Bengal : Chota Nagpur, Sahibganj ; 

 Sikkim : Mungphu ; Assam ; Siam ; but 

 Dr. Horn is of opinion that 

 is known only from Bengal 

 List of the Asiatic Beetles in 

 Museum, Part i, p. 2): the other localities 

 must therefore, apparently, be referred to allied species. 



Dr. Horn (D. E. Z. 1898, p. 273) believes that C. caviceps, 

 Klug, is the male of 0. longicollis, but he says that he has not 

 seen a trustworthy specimen of the male of the latter species.

This species is a little larger than the average specimens of C. longi- 

 collis and also differs from them in the black, somewhat opaque 

 colour, and the unspotted palpi and antennas, the latter having 

 the first six joints dark blue ; the pronotum is more elongate, 

 less deeply constricted before the base, with the intermediate
