Entomological notes, E. E. Green {Trop. Agr. and Mag. Ceylon Agr. Soc, 

 35 (1910), No. 3, pp. 221-223, p?. i).— Brief notes are presented on the African 

 snail [Achatina fulica), Clerus formicarius, a root-borer of Para rubber, a 

 mealy bug on cotton plants (Dactyiopiiis virgatus), nettle grub on tea {Natada 

 nararia), another scale pest of castilloa trees (Lecanimn olece), and the mango 

 weevil (Cryptorhynchus mangiferce) . 



List of names used in India for common insects, H. M. Lefroy (Agr. 

 Research Inst. Pusa [India'\, Bui. 19, 1910, tip. IV+J,9+XVII) .—This list gives 

 the vernacular, scientific, and English names and the habitat of a large number 

 of the insects destructive to crops in India. 



Two insects affecting- wheat and barley crops, P. Enock (Jour. Roy. Hort. 

 Soc. [London], 36. (1910), No. 2, pp. 323-330, figs. 5).— A brief account is given 

 of the life history of the Hessian fly as worked out by the author at Revells 

 Hall, England. Notes are then presented upon a cecidomyid pest that seriously 

 injured wheat and barley at Tenby, in 1908, which has been identified as 

 Clinodiplosis equestris. The larvaj were found between the joints, underneath 

 the leaf sheath, each in a cavity in the stalk -vs in. in length. 



Can mill insects in any stage pass uninjured through, the process of mill- 

 ing? G. A. Dean {Oper. Miller, 16 {1911), No. 2, p. 119, fig. i).— From experi- 

 ments conducted in which Tribolium confusum and SUvanus surmamensis were 

 used, the author concludes that " no egg or larva of the common mill insects 

 can pass uninjured through the rolls or the grinding process in the production 

 of the common brands of flour. No egg or larva of the common mill insects 

 can pass through the meshes of silk bolting cloth of sizes not less than No. 

 10 XX." 



A preliminary report on insects affecting maize in Southern Nigeria, 

 C. W. Jemmett {Lagos [South. Nigeria]: Govt., 1910, pp. Jf, pi. 1). — The Insects 

 mentioned are Calandra oryztr, G. granaria, and lepidopterous larvae. 



A preliminary report on grape insects, F. Z. Hartzell (Neio York State 

 Sta. Bui. 331, pp. 485-581, pis. 15, figs. 8). — In this bulletin the author presents 

 a report of the entomological work conducted since June 10, 1909, in connec- 

 tion with the Chautauqua County grape investigations. Particular attention 

 has been given to 5 of the more important pests, namely, the grape flea-beetle, 

 grape-blossom midge {Contarinia johnsoni), rose-chafer, grape root-worm, and 

 grape leaf-hopper. The economic importance, history, origin and distribution, 

 food plants, character and extent of injury, description of the insect, seasonal 

 history, summary of the life history, and control measures for each of these 

 species are dealt with. 



" The grape flea-beetle is a small, steel-blue beetle which feeds on the 

 swelling buds. The beetles appear during April and feed during the warmer 

 days. Mating takes place during a period of nearly 2 months. Egg-laying 

 extends over a period of nearly 2A months, but the greatest number of eggs 

 are laid during a month and a half extending from about May 1 to the middle 

 of June. The eggs are laid in the canes of the grape. The number of eggs 

 laid by a female was found to vary from 5 to 103. The eggs hatch the latter 

 part of June and early July and the larvae feed upon the foliage, reaching 

 full development in about 3 weeks. The larvae form cells in the ground and 

 transform to pupae in about 3 weeks. The adult beetles feed on the grape 

 foliage and later in the fall seek sheltered places to hibernate. The most 

 efficient spraying mixture is composed of 8 lbs. of arsenate of lead, 3 gal. of 

 glucose, and 100 gal. of water. This is applied in the spring as the beetles 

 are feeding on the vines. The use of the same spray will kill the larvae if 

 applied the first part of July.
