694 PROCEEDINGS OF THE THIRD ENTOMOLOGICAL MEETING 



It was found that these trees are sparse in the crab-infested districts. 

 Even if they were plentiful, the transportation-charges would be prohi- 

 bitive. 



The experiments of dragging with nets in the fields before sowing 

 and importing seedlings for transplanting into the fields after the migra- 

 tion of the Varuna litterata to avoid delay in sowing were suggested 

 by the Agricultural Chemist, but they are, says the Director of Agricul- 

 ture, Burma (in his letter No. 2808-1E-2, dated the 15th June 1918), 

 not hopeful as, even if demonstrated to be effective, the increased cost 

 of cultivation would probably deter cultivators from applying them. 



A few experiments with tobacco, yenan (crude earth-oil) and mahaga 

 might, if possible, be tried in the ensuing season in small plots ; but 

 these, even if they prove successful, would hardly appeal to the culti- 

 vators, as the treatment would be expensive on extensive areas. 



As the agricultural operations are delayed till the migration of the 

 Varuna crabs to the sea, the difficulty might be overcome if any late- 

 growing variety of paddy could be introduced into the localities subject 

 to infestation. 



The name of any such variety, if known, and a scheme of cheap 

 practicable experiments on the marine crabs and field-snails, if any 

 recommendable, might be communicated. 



Field-Snails. 



Ampullaria sp. (?) 



(Vernacular name Le-Jcayu.) 



As this snail is found in the fields, it is called Le-kayu (Field-snail : Le 

 field, kayu snail) by the cultivators. According to the Taking culti- 

 vators of the Amherst District, these snails eat up the paddy seeds which 

 are sown. The cultivators, therefore, collect and throw them into the 

 creeks before they start sowing. However, it has to be done twice or 

 even sometimes thrice in badly infested fields. Their number is so great 

 that half to one basketful of snails is collected from a plot of -5 acfe. 

 They generally infest swampy places. In the absence of rain, they 

 remain in the soil ; when the monsoon begins and the fields are ploughed, 

 they come out of the soil. 



34._ISTOTES ON THE RED WORMS FOUND IN THE NGACHIMA 

 PADDY AT HMAWBI. 



By K. D. Shroff, B.A., Entomological Assistant, Burma. 

 The presence of these worms was first noticed in Lower Burma by 

 the Assistant Botanist, Southern Cirde, in a hmited area and only in
