ENTOMOLOGY. 461 



Report of the assistant entomologist, H. O. Mabsh ([Bien.'] Rpt. Bd. 

 Comrs. Agr. and Forestry Hawaii, 1900-10, pp. 152-159). — Experiments on the 

 control of several insect enemies of truck crops, etc., including the Japanese 

 beetle (Adoretus temiimaculatus) , the melon fly {Dactts cueurbitw), the alli- 

 gator pear mealy bug (Pseudococcus nipoe), the chrysanthemum plant louse 

 (MacrosipJiiim sanborni), the beet worm (Hymenia fasciaUs), and insects 

 affecting the cabbage are briefly reported. 



Report on injurious insects in Finland, 1908, E. Reuter (Landthr. Stpr. 

 Meddel. [Finland], 1910, .Ao. 73, pp. 2o). — The author discusses the occurrence 

 of insect pests during the year. Charwas yru minis was the source of injury in 

 the district of Osterbotten. and the chrysomelid beetle Pha^adn armoraciw is 

 said to have injured turnips. 



Some insect pests of India, H. E. Houghton and M. AniNAKAVANAiYAn 

 (Cent. Agr. Com. Madras Bui. 10, 1911, pp. 6, figs. 2). — The insect posts noted 

 are the rice bug (Navai puchi), rice hispa, 2 coconut beetles, tobacco caterpil- 

 lar, and cane borers. 



Research work — Parasites, F. Tidswell (Rpt. Govt. Bur. Microbiol. N. S. 

 Wales, 1909, pp. 7.'i-99). — The author presents a list of the parasites occurring 

 in Australia, descriptions of certain parasites met with during the year, and 

 brief notes on treniatodes and nematodes. See also a previous note by Oleland 

 and Johnston (E. S. R., 24, p. 785). 



Synopsis, catalog-ue, and bibliography of North American Thysanoptera, 

 with descriptions of new species, D. Moulton (U. S. Dept. Ayr., Bur. Ent. 

 Bui. 21, tc.eh. ser., pp. 56, pis. 6). — This synopsis and catalogue lists a total of 

 118 species and varieties, representing 40 genera. Two genera, 10 species, and 

 1 variety are described as new to science. 



Burning chinch bugs, T. J. Headlee (Kansas Sta. Circ. 16, pp. 7, figs. G)-**— 

 Attention is called to the fact that during the fall chinch bugs gather in lai'ge 

 numbers in clump-forming gi'asses of badly infested sections and that most of 

 them can be destroyed by running fire over the infested grass lands in such a 

 way as to burn these clumps down close to the crowns. 



Report of entomologist, E. W. Beugek (Florida Sta. Rpt. 1910, pp. aeasm?- 

 xliv). — The greater part of this report is devoted to an account of sprayings 

 made with red Aschersonia, a general discussion of which has been previously 

 noted (E. g. R., 24, p. 355), and to the white fly situation in Florida in general. 



It is stated that, as a whole, the fungus work with the white fly at Gaines- 

 ville was a success. A sharp frost on December 30 and 31, 1909, defoliated 

 many trees in a part of the experimental grove, resulting in a great loss of 

 fungus but also causing a reduction of the white fly. Fungus collected on 

 March 11, 1909, was kept in cold storage until August 8. Three lots exposed 

 in various ways to temperatures of 12°, 20°, and 36° F., respectively, were 

 sprayed August 11 on sterilized sweet potato, but only spores from the lot 

 exposed to the temperature of 26° developed. 



On trees sprayed August 17, 1909, with potash whale-oil soap No. 3, at the 

 rate of 1 lb. to 9 gal. of water, 90 per cent of all larvse were destroyed. Similar 

 results were obtained from the use of Golddust and whale-oil soap in a Sat- 

 suma grove. As previously observed, these spraying solutions did not retard 

 the development of the fungus in the least. Whale-oil soap No. 3, 1 lb. to 6 gal. 

 of water, also a mixture of whale-oil soap and baking soda at the rate of 1 lb. 

 of the former to IJ lb. of the latter, in 8 gal. of water, destroyed nearly all 

 larvae up to the thickened condition of the fourth stage. Spraying experiments 

 showed that \ lb. of washing soda to 1 gal. of water and i lb. of borax to 1 gal. 

 of water give no beneficial results. Black leaf tobacco extract at the rate of
