CETONIIN^E 301 



7 Clypeus large, broadly obtuse at apex as a rule. Group VI (sepulchralis) 



Clypeus nearly flat, generally narrowed apically and more or less bilobate 

 at apex; body often very small in size, conspicuously pubescent to 

 almost completely glabrous 8 



8 Anterior tibiae tridentate; pygidium with concentric sculpture; 

 pronotum never having discal tomentose spots, always sinuate 

 medially at base; elytral costae variably developed. 



Group VII (biguttata) 



Anterior tibiae bidentate; pygidium with crescentic annular punctures; 

 pronotum with two discal vittae composed of detached tomentose 

 spots, the base not sinuate medially; elytral costae very feeble. 



Group VIII (insignis) 



These groups appear to be distinct among themselves and, as I 

 can find no intermediates, I presume that they are subgeneric in 

 nature. Possibly basalis or fascifera might be regarded as an addi- 

 tional group; they really have very little mutual affinity, apart 

 from the general scheme of elytral ornamentation, but that this 

 should be so similar in the two is very remarkable. 



Group I. 

 Subgenus Erirhipis Burm. 



There was considerable justification in the generic separation of 

 fulgida from sepulchralis, and if Erirhipis is not of full generic 

 value as maintained by Burmeister, it is certainly subgeneric; 

 besides the structural features mentioned above, there is a distinct 

 difference of facies, not only pertaining to fulgida, with its allied 

 forms, but to all the other groups as limited above. The species 

 in my collection may be recognized by the following characters : 



Clypeus large, parallel, with arcuate sides and broadly rounded, slightly 

 reflexed apex, which is more or less evidently, though always feebly, 



sinuate at the middle 2 



Clypeus longer, parabolic, the more narrowed apex moderately reflexed 



and obtusely, rather approximately bidentate 7 



2 Entire upper surface highly polished and metallic in lustre 3 



Entire upper surface opaque, the lower surface shining 6 



3 Pronotum without a pale lateral margin; legs dark, the femora in no 

 part paler. Body oblong-elongate, subparallel, feebly convex, bright 

 green above, the under surface and legs darker green; sides of the 

 elytra indigaceous; head small, strongly and rather closely punctate, 

 the two more punctured frontal areas moderately dense, the clypeal 

 margin truncate medially; antennal club (c?) a little longer than the 

 stem, nearly black; prothorax a third wider than long, the sides 

 nearly straight, feebly converging to the middle, then more strongly
