FAMILY BOSTRYCHIDAE i73 



In Chota Nagpur and the Central Provinces the insect is to be found 

 infesting sal wood, especially in the beams used in the construction of 

 bungalows. The insect also attacks sal in Dehra Dun, and, I think,. 

 Ajwi^cissus latifolia posts, both in Dehra Dun and the submontane sal areas. 

 In this part of India it also tunnels into khair {Acacia catechu), and may be 

 found in April-May engaged in this manner in trees felled for cutch-boiling. 

 In Mandla, in the Central Provinces, I have also taken the beetle from the 

 wood of Terminalia tomentosa and Pterocarpus niarsupmm. 



S. anale was taken in Burma by the late Mr. G. C). Corbett. In 1905 I 

 took it from bamboos {Dendrocalamus strictus ?) in the Mohnyin Forest m 

 Katha, from an undetermined species of bamboo on the Salween River 

 in Tenasserim, and from fuel billets of jungle woods on the Ataran River in 

 the same locality. I have not taken the beetle in Madras, nor can I find a 

 report of its existing in the Presidency. 



The protective and remedial measures already described for 5. crassum 

 apply equally to S. anale. It must, however, be borne in mind that this 

 beetle will oviposit in much drier wood. Dead standing trees, and accumu- 

 lations of large branches and tops, and rejected logs left lying in the forest, 

 or stacks of decaying firewood left standing in fuel depots, will attract this, 

 pest, and inevitably result in its great increase in the area. 



Most, and perhaps all, of the predaceous insects described under 



S. crassum probably prey also upon S. anale, since these 



Predaceous Foes. two bostrychid borers are commonly found in company 



riddling wood. 



In addition I add the following carabids, which may also attack 



S. crassum, though I have personally only found them preying upon 5. anale. 



Anthia sexguttata, Fabr. (p. 95).— A large black beetle with six large conspicuous white 

 spots, two on the thorax and four on the elytra. The mandibles are powerful, the thorax more 

 or less heart-shaped, and the elytra broad and rounded ; 

 legs long and powerful. Length, 43 mm. 



Life History.— This large carabid prob- 

 ably feeds upon a variety of insects, and 

 is often found high up on the trunks of trees 

 searching for bark insects and bark- and 

 wood-tunnellers. I took it at Changa Manga 

 towards the end of May 1905, quartering 

 the bark of a large semi-blown-down, still 

 green sissu-tree, which was being riddled by 

 S. anale beetles. The carabid was seizing 

 the beetles engaged in tunnelling into the 

 bark to get down into the sapwood. The 

 insect was also, I think, preying upon the 

 Bothrideres, Alindria, and Melambia beetles, 

 which were also ovipositing in company with Fig. 118. 



the S. anale and preying on the latter. Aji//iia sex^i^mtata, Ho. India.
