COLEOPTEKA. 
burrows and Lesne mentions a Colydiid beetle ( Bothrideres) which lives 
upon Sinoxylon crassum. Cleridce attack them also (Cylidrus, Denops, 
Tillus, Opilo, etc.), and a Melyrid (Axinotarsus) is also recorded. Hy- 
menopterous parasites are known but are uncommon. 
The family has recently been monographed by Lesne (Ann. Soc. 
Ent. France, 1896, p. 95; 1897, p. 319; 1898, p. 438 ; 1900, p. 473; 
1906, p 445). He divides it as follows :— 
I. Psoince. 
II. Polycaonince. 
III. Dinoderince. 
IV. Bostrichince. 
1. Bostrichines. Bostrichi. 
Xyloperthi. 
2. Apatines. 
3. Sinoxylonines. 
Of the Polycaonince , one Indian Heterarthron is recorded. The 
Dinoderince , Bostrichines and Sinoxylines are alone of any importance 
in India. In the first, five species of Dinoderus and one of Rhizopertha 
occurs in India. Of the Bostrichines , there are nine Bostrichi , and seven 
Xyloperthi recorded. In the Sinoxylines , 17 Indian species are recorded. 
Dinoderus distinctus., Le., attacks the branches of mango. 
pilifrons, Le., is bred in bamboos, both green and dry, as in wood. 
minutus , Fabr., is smaller than the prece¬ 
ding and is common also in bamboos. It 
was also found in cut sugarcane. Rhizo¬ 
pertha dominica, Fabr. (pusilla, F.), is a 
household pest boring into biscuits and 
other dry stored produce, as well as grain. 
It is apparently common in Indian houses 
and we have reared it from wheat flour. 
Bostrichopsis parallela, Le., is mentioned 
by E. P. Stebbing as boring in bamboos. 
Bostrychus aequalis, Wat. (fig. 19^), was 
found in tea-boxes from Calicut. Sinoxylon 
indicum, Le., has been captured in many 195 .— Dinoderus 
localities in South India and Burmah, but distinctus. [I. M. N.J
