nomenclature, including a review of the literature, the author deals with the 

 structure and mechanism of the mouth parts. A bibliography of 23 titles is 

 appended. 



The potato moth: An experimental investigation into the methods of con- 

 trolling its ravages in stored tubers, F. Stowakd (Ahs. in Jour. Nat. Hist, and 

 Sci. Soc. West. Aust., 5 (1914), pp. 15-19).— In a report of experiments in 

 which formalin, mercuric chlorid, copper sulphate, sodium carbonate, sulphuric 

 acid, arsenate of lead, phenol, carbon bisulphid, air-slaked lime, lime-sulphur, 

 etc., were used, carbon bisulphid alone gave satisfactory results in controlling 

 the ravages of Phthorimea operculcUa in stored potatoes. 



"The destruction of the larvse, either in the substance of the tuber or ex- 

 ternal to it, is accomplished by fumigating larva-infested tubers with this 

 compound at the rate of 1 or 2 lbs. per 1,000 cu. ft. of space for a periml of 16 

 hours. In the annihilation of the egg and pupa, however, using either of these 

 amounts of carbon bisulphid per unit of space, the fumigation period must not be 

 less than 48 hours, and to insure complete destruction of these life forms the 

 application of a second fumigation four to six days after the first is neces- 

 sary. . . . 



" In an experimental study of the influence of carbon bisulphid fumigation 

 on the vitality of the tuber buds, the culinary and storage qualities of the tuber 

 and the results of planting fumigated 'seed' tubers, the author reports that 

 sound, infested, and uninfested tubers may be intermittently fumigated with 

 1 to 2 lbs. of carbon l)isulphid per 1,000 cu. ft. of space for a period of 48 hours 

 two, three, or four times without causing injury to the tuber buds or impairing 

 the storage and edible qualities of the tuber." 



The tent caterpillar, H. T. Fernalu (Mass. Bd. Ayr. Circ. 46 (1915), pp. 5, 

 figs. 3). — A l)rief popular account. 



Observations on the biology of the grapevine moths and means for their 

 control, P. VoGLiNO (Bol. Min. Ayr., Iiuitm. c Com. [Rome], Ser. B, 14 {1915}, 

 II, No. 1-2, pp. 21-29). — This account relates to work with Cochylis avibiyuella 

 and Polychrosis hotrana in Italy in 1914. 



The prevention of egg laying on turnips by the diamond-back moth, 

 R. A. H. Gray (Jour. Bd. Ayr. [London]. 22 (1913), Xo. 3. pp. 222-226) .—Kyi- 

 periments conducted have led to the reconmiendation that when this moth 

 appears 2.5 cwt. of ground stone lime per acre be carefully broadcasted on the 

 young turnips, preferably on a dewy morning when there is no wind. 



Typical flies: A photographic atlas of Diptera, including Aphaniptera, E. 

 K. Peabce (Cambridge: University Press, 1915, pp. XI I +47, fiys. ioo).— This 

 consists largely of reproductions of photographs of representatives of the 

 various families of Diptera. 



The Chironomidse, or midges, of Illinois, with particular reference to the 

 species occurring in the Illinois River, J. R. Malloch (Bui. III. State Lab. 

 Xat. Hist., 10 (1915), Art. 6, pp. 273-5^3, pis. 2.'/). — This work, which is largely 

 systematic, presents tables for the separation and description of the species 

 occurring in Illinois. 



A sjmonymic catalogue of the dipterous family Phoridse. C T. BRt*ES (Bui. 

 Wis. Xat. Hist. Soe., n. ser., 12 (1914), Xo. 3-4, pp. 85-152).— This catalogue 

 lists the Phoridfe of the world, including the few fossil forms which have been 

 given names. Forty-six genera and 472 species are thus catalogued. 



Notes on the preoviposition period of the house fly, Musca domestica, 

 R. IT. HxTTCHisoN (V. S. Drpt. Ayr. Bui. 345 (1916), pp. 13. fly. /).— "From the 

 experiments reported in this paper it is setni that the shortest record for the 

 preoviposition period was one of about 2.^ days and the longest one of 2.S days, 

 with most of the records falling on the fourth, fifth, sixth, ninth, twelfth, and
