MISCELLANEOUS NOTES. 197 



characteristic triungulins. The eggs were deposited at the ends of the 

 galleries, and each mass must have contained several thousand individuals. 

 The full-grown larvce of the beetle excavate for themselves offshoots from 

 the tunnel of the bee, of a much smaller diameter and an inch or more in 

 length, in which they pupate. The fact that the young larvie are hatched 

 inside the nest of the bee suggests that at least some of them may pass 

 their whole larval existence on the spot ; but they are produced in such 

 vast numbers that for most of them a migration must be necessary. They 

 are doubtless unconsciously transported to fresh colonies by the bees them- 

 selves. I have frequently captured specimens of Xtjlocopa bearing examples 

 of the triungulins attached to their hairy legs. On one occasion I 

 found a single trimigulin on the stamens of a large blue Thunbergia, the 

 blossoms of which are frequented by the Xylocopa. It is noticeable that 

 the male bees are more constantly utilized by the triungulins than the 

 females."

No. X v.— LOCUSTS IN NORTH BENGAL. 



The Dooars is the country which is situated under the Himalayas in 

 the District of Jalpaiguri. It is an extension of the Terai which is to 

 the west. The rainfall is very large, and varies from 120 to perhaps 250 

 inches. 



On Thursday, the 8th July, a great swarm of locusts arrived, apparently 

 from the south or south-east. Tea gardens from a distance of ten miles 

 away report that all were visited by millions of the insects. The locusts 

 arrived about 4 p.m. and stopped until 1 p.m. on the following day and 

 sometimes longer. They attacked the nitrogenous shade trees and green 

 crops — Albizzia stijmlata — Tephrosia Candida and such like, and did consider- 

 able damage. Fortunately, however, the tea was not badly damaged, only 

 young, soft leaves here and there having been eaten. The locusts may 

 have occupied even a larger extent of country than the 10 to 12 miles in 

 width of which I am at present informed,
