longing to varions orders with brief ainiotations regarding the locality where 

 they are found and the host plants. 



Physiology of aberrations and variations of butterflies, E. Fischer (Arch. 

 Rofisen n. Gcsell. Biol., .'/ (]'.)07), Xo. 6, pp. 761-703, pi. 1). — The literature re- 

 lating to the influence of temperature changes and other external factors upon 

 the variations of butterflies is critically examined. The author's experiments 

 were made on species of Vanessa, Pyi-ameis, and Araschnia. It was found pos- 

 sible by means of decided temperature differences to produce striking altera- 

 tions in the general color patterns of these insects. 



The course of absolute inanition in Carabus morbillosus in diffused light 

 and in darkness, (i. Fatta and S. ;Mundula (Studi .S'«s«fl/c.s/, J (J!)07-S), Sect. 

 2. Slip. 2. pp. 27). — Ground beetles belonging to the species Cnrubus morbillosus, 

 having an initial weight of 0.71 gm., lived during complete fasting for o3S hours 

 on an average, losing during this time 34 per cent of their weight or 0.1 per cent 

 hourly. Beetles which were fasted in complete darkness as compared with 

 those which were kept in the light lived longer and the hourly loss of weight 

 was less. 



On the biologies of the Rhynchophora of North America, W, D. Pierce 

 (Ann. Rpt. Xchr. Bd. Agr., 1906-7, pp. 2'i7-31D. pis. 8). — The author presents a 

 comprehensive account of our present knowledge regarding the biology of the 

 species of weevils which occur in the United vStates. Particular attention is 

 given to the biology and economic relations of the more important species. A 

 bibliography of the subject is appended to the article. 



Coccidae of Japan, S. I. Kuwana (Bui. Imp. Cent. Agr. Expt. 8ta. Japan, 1 

 (1907), No. 2, pp. 177-231, pis. 9). — According to the collections made by the 

 author in Japan during the past 3 years, there are 97 species of Coccidse in 

 Japan, 13 of which are described as new. Brief notes are given on these species 

 and a list is presented of other scale insects reported as existing in Japan but 

 not observed by the author. 



A special account is given of Xijlococcus niatsunuircc, a new species of scale 

 insect observed on pines, and a general account of the anatomy, habits, and life 

 history of Gossypcria ulmi. 



Notes on the Egyptian cotton bug or cotton stainer (Yearbook Kliediv. 

 Agr. Soc. Cairo, 1906. pp. 11-27, pi. 1). — The most important species of cotton 

 stainer in Egypt is Oxi/careniis Injalinipennis, which is found on cotton and a 

 number of other plants belonging to the mallow family. The pest is describe<l 

 in its various stages and notes are given on its life history. The number of 

 annual generations has not been determined. In addition to the well-known 

 fact that these and other related insects cause a staining of the cotton fiber in 

 picking and ginning, the pest also causes serious injury by sucking the juices 

 from the squares of young bolls. It is suggested that the insect might be to 

 some extent controlled by hand picking, but more particularly by clean cultiva- 

 tion and the destruction of all rubbish in the cotton field. 



Thrips on oats, 11. II. Pettit (Michigan Sta. Spec. Bui. 3S, p. 1). — An injury 

 to young oats resembling blight was reported as causing damage in a large part 

 of the State. The cause of the trouble is stated to be thrips, which were present 

 in unusual nnnii)ers. 



Control of the brown ant (Solenopsis geminata) and the mealy bug 

 (Pseudococcus citri) in pineapple plantations, W. V. Tower (Porto Rico Sta. 

 Circ. 7, pp. 3). — The brown ant seldom does any direct damage to pineapples 

 but it attends the mealy bugs and carries them from place to place distributing 

 them upon fresh plants. The attack is usually made on the outer rows of the 

 plantation. Before the flower stalk develoits the mealy bugs are found on the 

 leaves near the center of the plant.
