358 EXPERIMENT STATION RECOKD. 



Fischer's studies wen- willi ilie mm moth (Psiliiid inonaclia).. hut with these 

 at hand the author has condueted experiments witli the gipsy niotli which he 

 here describes in detail. In the first experiment, in which caterpillars dead 

 from the disease were distributed on trees infected by caterpillars in the 

 third instar, 55 to 60 per cent died by the time of pupation. In a second 

 experiment with caterpillars in the fourtli instar. Infected in a similar manner, 

 65 per cent were dead before the time of pupation. In a third experiment, in 

 which caterpillars in the fourth instar were infected by painting the trunks 

 of trees with a ring of a mixture of water, glue, and caterpillars dead from the 

 disease, 63 per cent were dead at the time of pupation. In the fourth experi- 

 ment a mixture similar to that used in the third was sprayed upon the foliage 

 while the caterjiillars were in the fourth instar, 70 per cent dying before the 

 time of pui)ation. In a fifth experiment, in which dead larvae were dried, 

 powdered, and stirred into water and glue added to make the mixture adhere 

 to the leaves upon which it was sprayed while the caterpillars were in the 

 fourth instar, but 40 per cent died before pupation. 



In all these experiments the pupae still remaining were looked for later 

 and it was found that an average of 10 to 15 per cent had died from flacherie. 

 From these results the author concludes that the artificially produced flacherie 

 can be utilized as a valuable aid in the destruction of gipsy-moth caterpillars. 

 However, further experiments should be made on a larger scale to substantiate 

 the results obtained. 



In experiments with the brown-tail moth similar to those performed with the 

 gipsy moth only 2 per cent of the caterpillars succumbed to the disease. Near 

 Raymond, N. H., a wooded area was found where flacherie had broken out, 

 especially among the tent caterpillars and those of various Xoctuidse, but in 

 spite of the presence of the brown-tail caterpillars in large numbers a mortality 

 of only 2 per cent by flacherie appeared among them. 



A revision of the Arctianae of Japan, T. Miyake (Bui. Col. Agr., Tokyo 

 Imp. Univ.. 8 {1909). No. 2, pp. IBS-lUi. ftgs. 6). — Of the 32 species recognized 

 as belonging to this subfamily, 8 are peculiar to Japan. 5 being found in Japan 

 proper, and the other 3 limited to Formosa. Of the remaining 24 species, 14 

 are palaearctic, 7 oriental, and 3 common to both regions. 



On certain Pieris caterpillars, W. T. M. Forbes (Psyche, 16 (1909), No. 4, 

 pp. 69-73. figs. 9). — Breeding notes on Pieris daplidice, P. brassicw, and P. 

 raprr are given. 



Notes on the eggs of Epagoge sulphureana, R. L. Webster (Ent. News, 

 20 ( 1909). No. 0, pp. 389, 390). — A specimen of this moth bred from a larva col- 

 lected on apple nursery stock in Iowa is reported to have deposited 263 eggs. 



A lepidopterous pest of coconuts, Brachartona catoxantha, 11. C. Pratt 

 (Dcpt. Agr. Fed. Malay States, Bui. 4, P- 6; Agr. Bui. Straits and Fed. Malay 

 States, 8 (1909), No. 8, pp. 357-362). — Although the owners of coconut planta- 

 tions in the Federated Malay States have had in the luist but few insect pests 

 to combat, with the exception of the coconut beetle, during the past 3 years 

 Brachartona catoxantha has appeared in two widely separated localities. Its 

 somewhat sporadic occurrence as a pest appears to be due to the diminution of 

 its parasites, perhaps on account of the presence of a hyper-parasite. At Fusing 

 Bharu, about 20 per cent of the third brood of caterpillars were found to be 

 parasitized. 



An account is given of the life history of the pest accompanied by descrip- 

 tions of its stages. A period of 5 to 6 weeks is required for the completion of 

 its life cycle from egg to moth and approximately 10 days for the appearance 

 of another brood. Five broods may appear before the insect is reduced by 

 parasites. Kerosene emulsion was found to be far more effective than London
