E. Lopez Vallejo. Estro del Carnero. Boletin No.21,Estacion 

 Agricola Central, 1909. 



This bulletin deals with Oestrus ovis which is said to be very abundant throughout 

 the republic of INIexico. In Mexico City it appears that the majority of the sheep 

 and goats which are slaughtered are infested with this parasite. Considerable 

 information regarding life history and development is given and preventive and 

 direct measures of control are discussed. 



Francisco Lopez Vallejo. Algunas Enfermedades del Ganado 

 Ovino. Bolatin No. 49, Estacion Agricola Central, 1910. 



The author discusses the diseases of sheep in general but a large portion of the 

 bulletin is devoted to the insect and Acarid parasites of these animals. The species 

 included are Sarcoptes scabei; Psoropies communis, Tnchodedes sp. and Melo- 

 phagus ovinus. Appropriate methods of treatment are given in the discussion of 

 each species.

Butterfly-Hunting in Many Lands, Notes of a Field Naturalist, by 

 George B. Longstaff. Longmans, Green, & Co., 1912, pp. XVIII — 

 724,, 16 plates (7 colored) 



The author has given us in this bulk.y volume, a narrative account of his experi- 

 ences in collecting insects in widely separated countries, such as Asia, South 

 Africa, Canada, India, Australia and New Zealand. The work is enhvened bj^ inci- 

 dental and more or less irrelevant notes relating to achievements or exiieriences, 

 such as cUmbing a volcano and the results of an earthquake. Nearly 500 pages are 

 devoted to this form of record, the butterflies hardly receiving more attention than 

 the moths, and there being in addition, observations on numerous other insects belong- 

 ing to various orders. The time spent in each country was necessarily limited and the 

 hsts of species are of little value so far as indicating geographical distribution. 



The more important observations on habits, ets., are discussed in a chapter on 

 bionomics, which gives considerable data on scents, color, juices, tenacity of life, 

 mutilation, experiments on palatability, mimicry, etc. An appendix gives trans- 

 lations of twelve papers by Fritz INIuller, deahng with the scent organs of butterflies 

 and largely inaccessible to naturalists, since they were pubhshed in the Ai-chivos do 

 Museu Nacional do Rio de Janeiro or other nearly as inaccessible jom-nals. The 

 plates are excellent and the value of the work materially enhanced by a compre- 

 hensive index. This volume will appeal mostly to general collectors and students 

 of bionomics. 



The More Important Insects and Fungous Enemies of the Fruit 

 and Foliage of the Apple, by A. L. Quaintance and W. I\L Scott. 

 U. S. Department of Agriculture, Farmers Bulletin 492, p. 1-48, 1912. 



This popular bulletin gives summary accoimts of a number of the more important 

 insects, such as the codUng moth, plimn curculio, canker worms, and of such diseases 

 as apple scab, bitter rot, apple blotch and cedar rust. There are a few brief remarks 

 on the possibihty of controUing San Jose scale by the use of dilute Ume-sulfur washes, 

 otherwise this insect is ignored, and the reason is probably due to this pest being
