broad and a little dilated in front, with its front edge straight 

 and sharjjly ridged. Specimens of this phase may be slightly 

 larger or a little smaller than the largest examples of the 

 inconstant phase and both jihases occur together. The strong 

 2-cusped branch of the mandible in the constant phase has no 

 apparent correspondence with the median tooth found in large 

 specimens of the variable jjhase, which is pointed, has a 

 downward direction and is placed before instead of after the 

 middle.

There seems to be no reason to doubt that C. carinatus is 

 confined to Ceylon, although owing to careless labelling of 

 specimens it has long been believed to inhabit the mainland 

 of India, and even to range as far as Calcutta. 



De\Tolle considered that three species could be distinguished 

 amongst the forms here united and Boileau, whilst rejecting 

 intermedins Deyr., believed that the very smooth and shining 

 specimens called by Deyrolle Odontolahis nigritus, formed 

 a distinct species. Comparison of a very large series, many of 

 them kindly lent by ^Ir. C. Henry, of the Colombo Museum, 

 appears to me to show conclusively that no breaks whatever 

 occur except that between the two male phases.

Coppery, with variable greenish or purplish reflections, the 

 up])er and lower surfaces dull in the male, more shining in the 

 female. The body rather short and broad, not very convex, 

 the legs fairly long. 



5. Darker in colour than the male and shining except at the 

 sides and extremities. The lx)dy is oval, more convex than 

 that of the male, with much shorter legs. The head is closely 

 punctured, rugo.se in front, bluntly produced laterally, with 

 fairly large eyes. The pronotum is rather strongly punctured, 

 closely at the sides but not in the middle. The front angles 

 are not ve-ry sharp, the sides are gently rounded to the lateral
