SECTION I. 



The stoutly-built abdomen and very short elytra, the uniformly 

 rounded base of the pronotum, and still more the curious shape 

 of the clypeus of the male, give the small species allied to 

 A. tenella, EL, and A. hindu, Hell., a peculiar aspect, and have led 

 to their being formed into a separate genus, Singhala. I have 

 not been able to adopt this, however, for no substantial differ- 

 ential characters can be found for it, except the sexual features 

 in the clypeus of the male and the elytral dilatation of the female, 

 both of which recur in Anomala dorsalis, F. (constituting 

 Section II), to which, in spite of its very different size and 

 shape, these little species seem to show an interesting relation- 

 ship. A. dorsalis, F., however, cannot naturally be dissociated 

 from the dull-coloured group of Anomalas with three-toothed 

 front tibiae forming part of Section III, and its points of differ- 

 ence from the Singhala group are as important as its points of 

 similarity.
