a pest. Tbe reader should consult the account of Dunning (Tr. Ent. 
Soc., London, 1868, p. 105), of Bidie (Report on the Ravages of the 
Borer, 1869, Madras), and that of Taylor (The White Borer, 1868, 
Madras). 
Caloclytus is a large genus of yellow banded beetles, one of which is 
occasionally extremely abundant in the plains. This is C. annularis, 
Fab., a slender beetle clothed 
in yellow pubescence, with 
dark bands on the thorax and 
elytra ; it lays its eggs on 
bamboos, the larva living in 
the bamboo and gradually 
destroying it ; the life-history 
occupies one year, the beetle 
being easily reared in capti¬ 
vity ; large numbers have been 
found to emerge from a that¬ 
ched roof in which new bam¬ 
boos were used, their emergence 
taking place in May. Other species are extremely common in the hills, 
as are also some species of Clytus and Demonax. 
Lamiince. —The revision of this sub-family is not yet complete 
and we can only mention the common species of the plains, with the 
caution that the publication of the revision in the Fauna Volume will 
inevitably alter the nomenclature of the species named. Batocera 
rubra, Linn. (figs. 245 and 247), is the large beetle found throughout the 
plains, whose larva is common under the bark of trees ; it appears to 
occur chiefly in decaying bark and the trees felled in Pusa contained 
abundance of the large larvae and pupae. It is an extremely handsome 
insect, the largest of the common plains species. It is common also 
in mango, and E. P. Stebbing has described its occurrence in the Duld 
fig (Ind. For. Bull. 10). Ccelosterna spinator, F.,is a common beetle, 
breeding in babul (Acacia arabica) ; the beetle has been found to eat 
the bark of cotton plants and, when abundant, as it occasionally is to 
do harm in this way. C. scabrata , F. (figs. 246 and 255), has been 
reared from Casuarina equisetifolia in South India, where it is very 
destructive to young trees, and also from mulberry. Sthenias gnsator,
