A contribution to the physiology and morphology of the digestive appa- 

 ratus of insects, C. Schlutek (Ztschr. AUg. Physiol., 13 {1912), No. 3, pp. 

 ]')5-200, pis. 3). — This account includes a bibliography of 42 titles. 



Insect pest survey, H. L. Russkll {Wisconsin Sta. Bui. 218, pp. 28-25). — It 

 is stated that following the nearly complete loss of fruit by the late spring 

 freeze in 1910. the majority of fruit insects were left without their normal 

 food, and, consequently, but few completed their life cycle for winter hiberna- 

 tion. The codling moth and plum curculio were almost entirely eliminated as 

 destructive factors in fruit growing in some regions. The pear slug is said 

 to be reaching proportions where much damage is annually occasioned to the 

 cherry and plum. The apple aphis was unusually abundant during the year, 

 and the growth of young trees stuutotl thereby. The cottony maple scale was 

 again abundant, and the asi)aragus beetle was reported from several sections. 

 Both the onion thrijjs and onion maggot are causing severe losses in the truck- 

 ing regions in the southeastern part of the State. Locusts or grasshoppers 

 were unusually destructive in some sections, likewise the blister beetles, which 

 have caused no little injury to alfalfa and vetch. The damage by blister 

 beetles is partly atoned for by the good which their larvae accomplish in 

 feeding on grasshopper eggs which they destroy by the thousands. 



Farmers' foes and their remedies {Dept. Agr. Brit. Colinnbia Bui. 2^ 

 [1D08], pp. 200, figsi. 73). — This compilation deals largely with insect pests 

 occurring in British Columbia and remedial measures therefor. A chapter on 

 plant diseases is included. 



Insect pests in the West Indies in 1911 {Agr. News [Barbados], 11 {1912), 

 No. 2.7}, pp. 2G, 21). — This is a brief account of the more important insect pests 

 of the year in the British West Indies. 



Insect notes for the year 1910-11, P. L. Guppy {Bd. Agr. Trinidad Circ. 3, 

 1911, pp. 3-1 'i. Jigs. 2). — This ))apcr, which is a more extended account than 

 that previously noted (E. S. R., 25, p. 357), deals with the insect enemies of 

 cacao, rubber, tobacco, cotton, and other crops. 



Miscellaneous notes, F. W. Urich {Bd. Agr. Trinidad Circ. 3, 1911, pp. 

 15-25, flg. Jt). — Miscellaneous papers are here presented. The first, which re- 

 lates to ants on cacao estates, includes a preliminary list of 69 forms of Trini- 

 dad ants ; the second deals with rats and other mammals on cacao estates ; the 

 third consists of notes on insecticides, etc. 



[Destructive insects, 1910] {Bd. Agr. and Fisheries [London's, Ann. Rpt. 

 ■Intel. Dir., 1910-11. pt. 2, pp. 27-3S, pi. 1). — Among the more important insects 

 considered in this report are the grapevine phylloxera, the large larch sawfly 

 {Nematus criehsonii), the potato tuber worm, the cherry fruit fly {Rhagoletis 

 cerasi), the narcissus fly {Merodon equcstris), etc. 



Beport of the entomological section of the Wellcome Tropical Research 

 Laboratories, H. H. King {Rpt. Wellcome Research Labs. Gordon Mem. Col. 

 Khartoum, J, {1911), B. Gen. Sci., pp. 95-150, pis. 7, figs. 30).— The author first 

 reports upon animals injurious to man and animals, including mosquitoes and 

 their control ; blood-sucking flies other than mosquitoes, particularly tabanids, 

 with a list of blood-sucking flies recorded from the Anglo-Egyptian Sudan with 

 the localities in which they are known to occur ; CEstrida? ; and ticks. The 

 animals injurious to farm and garden crops considered include the Dura stem- 

 borer {Sesamia cretica), the black or greasy cutworm {Agrotis ypsilon), the 

 asal fly {Aphis sorghi), the cotton stem borer {Sphenoptera neglecta), the 

 melon weevil {Baris tragardhi), the melon stem borer {Apomecyna binubila), 

 the melon leaf beetle {Aulneophora foveicollis) , the diamond-back moth {Plvi- 

 tella niaculipennis) , the cabbage bug {Bagrada picta), the rigla gall weevil
