Report on rabbit branch, A. Crawford (Jour. Dcpt. A(/r. West. Aust., 15 

 (1907). \o. 12, pp. 935-938). — The campaign against rabbits in Western 

 Australia is being pushed vigorously. Complaint is made that many of the 

 individual farmers are disposed to allow the government to bear the whole 

 burden and do not even assist by the destruction of rabbits on their own farms. 

 The methods employed include the use of rabbit-proof fences, encouragement of 

 tile natural enemies of rabbits including iguanas, hawks, etc., and killing all 

 doe ralibits which are caught by various trapping devices (tlie buck rabbits 

 being set free). 



Observations on the food of a number of birds, N. Passerini and G. Cecconi 

 (Boi. 1st. Agr. Scandicci. 2. ser., 7 (1908), Ao. 1, pp. 12-102).— The authors 

 studied the kind of. food eaten by a large number of wild birds and on the 

 basis of the data obtained classified them in acc(n-dance with their food habits. 



The Iccust-destroying birds of the Transvaal, F. W. D'Evelyn (Condor, 

 10 (1908), No. 1, pp. 10-1 J/). — Descriptive notes are given on the liabits of 

 various birds which have been observed to feed upon locusts in the Transvaal. 

 Special mention is made of storks, starlings, guinea fowls, and the secretary 

 bird. 



Some observations concerning the effects of freezing on insect larvse, .J. S. 

 HiNE (Ohio Nat., 8 (1908), No. .',, pp. 258-260). — The larvre of BcJlura obtiqua 

 were placed in w^ater over night and exposed to a temperature of — 15° F. This 

 process was repeated for 6 nights, the temperatures ranging from — 6 to — 16° F. 

 None rf the larvje was injured. Tlie larvte of the tomato hawk moth were 

 killed by a frost severe enough to kill tomato vines. Similarly with larvie of 

 the fall cankerworm a frost on INIay 4 killed a large number of them. 



The more important insects injurious to Indian agriculture, H. M. Lefroy 

 (Mem. Dcpt. Agr. India, Ent. 8cr., 1 (1907), No. 2, pp. V + 113-252, figs. 82).— 

 A description is given in systematic order of the insects known to be injurious 

 (o crops in India. No list of economic insects has previously been published 

 for this territory and it is believed that the bulletin will be of service to eco- 

 nomic entomologists. In the case of each insect a brief description is given 

 with notes on its distribution, biology, food plants, and the extent of its 

 injuries. 



The Indian surface caterpillars of the genus Agrotis, H. M. Lefroy and 

 C. C. Uhosh (Mem. Dept. Agr. India, Ent. Ser., 1 (1907), No. 3, pp. 253-27.',, pi. 

 1). — Several species of Agrotis and Euxoa are described in detail and notes are 

 given on their biology. Particular attention is given to a discussion of 

 Agrotis ypsilon.
