1068 EXPERIMENT STATION RECORD. 



A discussion is also given of tlie injury caused by the beotlt'. The insect, is described 

 in detail in its various stages. 



The author believes that there is no urgent demand for insecticide methods against 

 this insect, since apparently its attacks are for the most part confined to sugar cane 

 which is already infested with some fungus disease. The prompt removal and de- 

 struction of canes which are infested with any fungus disease is suggested as a good 

 means for preventing further injury by the shot borer. 



The fruit fly, A. H. Benso.n* {Queensland Agr. Jonr., 7 {1900), No. 6, p. 534). — For 

 the destrui-tion of this insect the author reconnnends that all infested fruit should be 

 boile<l. It is considered esi)ecially important to destroy the early brood of larviO. 



The Dermaptera and Orthoptera of Austro-Hung-ary and Germany, J. 

 Reutenbacher {Die Derniatopteren unci OrOiopteren von OHlerreldi- Vnyurm und iJeutsch- 

 land. Vienna: Carl Gerald's Son, 1900, pp. 1^8, p>l. 1) . — The author discusses briefly 

 the general anatomy, different methods of capture and study of these groups of 

 insects. A systematic account is presented of the different species which occur within 

 the limits indicated. A bililiography of the suljject is apjyended. 



Illustrated analytical fauna of the Orthoptera of France, C. Houlbert 

 [Faune analytique illustree de^ Orthopteres de France. Paris: Einile Beyrolle' s Sons, 1900, 

 pp. 55, figs. 218). — The author gives analytical tables by which the species of 

 Orthoptera which occur in France may be determined. The majority of the species 

 are illustrated. The anatomy of this group of insects is briefly discussed, and a 

 bibliography of related literature is given. 



The natural history of the British liepidoptera, J. AV. Tutt {London: Sivan 

 Sonncnsc]i(l)i il- Co., 1899, Vol. I, pp. 500). — The jjresent volume is divided into 2 parts, 

 of which the first contains a general discussion of the origin of Lepidoi)tera, the egg, 

 embryology, parthenogenesis, external and internal structure of caterpillars, vaiui- 

 tion of moths, protective coloration, and a system of classification of Lepidoptera. 

 The second part of the volume begins a detailed discussion of the families of this 

 order. The practical value of this volume is considerably increased by full biblio- 

 graphical references. 



The critical point in insects and the origin of butterfly aberrations, P. 

 B.\CHMETJEW {Illus. Ztsckr. Ent.,5 {1900) , No. 6, pp. 86-89). — If adult or larval insects 

 are kept at a temperature of — 25° C. their body temperature is gradually diminished, 

 and during this time certain peculiar developments are observed. At about — 10° C. 

 the body temperature of the insects is suddenly elevated up to — 1.5° C. or to 0° C. 

 The elevation of temperature is explained by supposing that latent heat is set free by 

 the process of ])assing into the so-called cold rigor. The ul^servations of the author 

 were carried out \\\Hm a consideral)le varit'ty of inserts. 



On certain seasonal phases of butterflies of the genus Precis, A. <t. Bitler 

 {Entomologist, 34 {1901), No. 452, p. 7). — A brief discussion of the various forms of the 

 species belonging to this genus. 



Description of a new^ species of Aleurodes destructive to betel, (i. B. Buck- 

 ton {Indian Mas. Notes, 5 {1900), No. 2, p. 36, figs. 3). — A species described under 

 the name ^1. nubilans is reported as occurring in large numbers on the under side of 

 betel leaves in the form of small scales, difficult to detach. The larvse were tufted 

 with yellow material, each thread forming a continuous si)iracle. 



On the occurrence of Colias edusa and C. hyala, and the results of rearing 

 the variety helice from helice ova, F. W. Fkohawk ( Entdmolngist, 34 (1901), No. 

 452, pp. 2-5). — The results obtained from experiments with tlie variety helice indi- 

 cated that this forni was almost as numerous as the normal females, the same number 

 of each having emerged for several days. 



The clavrs and pulvilli of Diptera, J. J. Kieffer {Illns. Ztschr. EnL, 5 {1900), 

 No. 22, pp. 339, 340, pi. 1). — A brief anatomical study of the structures. 



Notes on the life history of Anopheles maculipennis, L. W. Sambon {British 

 Med. Jour., 1901, No. 2091, Epii., pp. 195-199, pi. 1, figs. 8).— The author describes
