456 EXPEEIMENT STATION RECOED. 



Providence, R. I., through the soiitheru part of New Hampshire, and into east- 

 ern Maine to a point nearly to Bangor. Another species, the Pteromalus 

 egregius, referred to in previous reports, and which destroys the brown-tail 

 caterpillars in the winter web, has been found in small numbers over a widely 

 scattered area in Massachusetts, New Hampshire, and Maine. Two other 

 species have greatly increased their range; these are Apanteles lacteicolor and 

 Meteorus versicolor.'''' 



Some very good results are thought to have been obtained in several places 

 from work with the gipsy moth wilt disease, the work with which will be 

 prosecuted on a much larger scale during the following year. More plantings 

 of the brown-tail fungus were made with apparently excellent results. The 

 fungus disease of the gipsy moth is said to still be in the experimental stage. 

 The conditions of the moth work at the present time in cities and towns in the 

 infested district are described.

3yLosquitoes and river vessels, A. Balfoub (Lancet [London], 1912, I, No. 16, 

 pp. 1048-1051, fig. 1). — The author states that the constant attention which has 

 been given has not prevented the invasion of Khartum every now and then by 

 mosquitoes (Stegomyia fasciata, Culex fatigans, etc.) from steamers and boats 

 plying on the Nile. " Not a year passes but that cases of locally acquired 

 malaria are traced, more or less definitely, to infected anophelines brought 

 into the town precincts by river vessels." 



Some parasites of Simulium larvae and their effects on the development 

 of the host, E. H. Strickland (Biol. Bui, 21 (1911), No. 5, pp. 302-338, pis. 

 5). — Two parasites, one a worm (Mermis sp.) and the other a new sporozoon 

 for which the name Olugea polyrnorpha is proposed, have been found by the 

 author commonly to infest Simulium larvte (8. hirtipes and an undescribed 

 species) in streams in the vicinity of Forest Hills, Mass. The Mermis does not 

 affect the larval development to any extent, except by slightly increasing its 

 size, but it inhibits the development of the histoblasts to such an extent that
