The next five segments are divided into three ridges above, each 

 ridge bearing a broad band of these hairs and spines. 



The seventh abdominal segment consists above of an anterior 

 ridge resembling in all respects the ridges of preceding segments, 

 and an extensive posterior flattened area divided across the middle 

 by a somewhat indistinct groove, and more or less covered with 

 hair which is longest in two places, in front of and behind this 

 groove respectively. 



The eighth and ninth abdominal segments resemble the seventh, 

 except that the anterior ridge is absent, and that the groove divid- 

 ing the flattened area is distinct, especially in the eighth segment. 



The tenth abdominal segment bears a large oval hairless area 

 above, bounded by a fine dark line which is incomplete behind, 

 and surrounded by dense and moderately long hair (pi. xiv, fig. 5). 

 Ventrally the posterior border is set with long erect spines, bent 

 over backwards at the tip. This border is terminated on each 

 side by a small patch of slender hairs, and there are a few scat- 

 tered spines and hairs further back. 



The eleventh abdominal segment is hairless and scarcely 

 exposed above ; below it is covered with long erect spines bent 

 over backwards at the tip, the lower margin of the anus bearing a 

 line of long slender hairs. 



Adoretus versutus, Harold. 

 PI. xiv, fig. 4. 



Locality. — Museum compound, Calcutta. 



Numerous larvae, about 7-30 mm. long. They were found 

 together with pupae and adults with larval exuviae, in flower-pots 

 in which cannas were growing. 



The larvae of A. versutus resemble those of A . lacustris in gene- 

 ral appearance, except that they are of a pale yellowish colour. 



The head is much less hairy than in larvae of ^, lacustris, 

 especially towards the vertex, and the clypeus is somewhat deeper. 

 The antennae are somewhat shorter, and the distal prolongation 

 of the fourth joint is blunter. 



The mandibles resemble those of A. lacustris in their general 

 structure, but the distal denticle of the triangular cusp on the 

 right mandible is very weak, and the second cusp, though strongly 

 elevated, is not strongly produced proximally, being in consequence 

 less distinctly L-shaped and more or less transverse to the man- 

 dible. The rest of the mouthparts closely resemble those of A. 

 lacustris, but the palps are somewhat shorter and stouter. 



The legs and body up to the ninth abdominal segment closely 

 resemble those of A. lacustris, except that the hair and spines on 

 the dorsal surface are weaker and less numerous. The tenth ab- 

 dominal segment resembles that of A . lacustris below, except that the 

 spines are much shorter. It is sparsely hairy all over above, the 

 hairs being most numerous and mixed with small spines near the
