other insect pests. The buds of apple and pear trees were injured to some 

 extent by Mi/ochroxs .s(jiiaiiiosus. 



Insects of German East Africa, H. P. Berensberg (Natal Ac/r. Jour, and 

 Miu. Rcc. JO (1907), No. J, pp. 50-55). — A brief account of locusts, cotton 

 insects, and tlie pests of castor-oil beans. 



Report on the orchards and fruit plantations of Worcestershire, F. V. 

 Theobald (Worcester: Worcestershire Ed. Com., 1906. pp. 30). — Notes are 

 presented on the chief insect and fungus diseases observed in various orchards 

 in different districts of Worcestershire. A list of 43 insects and 10 fungus 

 diseases is given as found in the trips of inspection. Particular attention is 

 devoted to the woolly aphis, green aphis, apple psylla, shot-hole fungus, etc. 

 Insecticide treatment is recommended for apple psylla, woolly aphis, oyster- 

 shell bark-louse, Hiialoptcrus priini. Aphis priiiii, etc. 



Some miscellaneous results of the work of the Bureau of Entomology, 

 IX. The Mexican conchuela in western Texas in 1905, A. W. Mokriij, 

 (U. aS'. Dept. Agr.. Bur. Ent. Bui. G'l, pt. 1, pp. l~lJf. pi. 1, figs. 2). — Pentatoma 

 liguta was reported as causing much damage to alfalfa, milo maize, cotton, and 

 a number of other crops Some injury was also observed on peaches and grapes. 

 The life history and habits of this insect are discussed, with notes on its 

 natural enemies, both parasitic and predaceous. 



Where this l)ug occurs in large numbers it is inadvisable to attempt to ripen 

 a crop of alfalfa seed during July and August. The only satisfactory method 

 for combating this pest is by means of hand nets and various forms of jarring 

 apparatus according to the crop attacked. 



Some miscellaneous results of the work of the Bureau of Entomology, 

 IX. Notes on the economic importance of sowbugs, W. I>. Pierce ( U. »S'. 

 Dept. Afir., Bur. Ent. Bid. (j'l, i)t. 2, pp. 15-22, pi. 1). — Particular attention is 

 given to a discussion of the life history and habits of ArmadilUdimn vulgarc, 

 which, for several years, has been reported as causing injury to various crops 

 in Texas. This species of sowbug attacks cotton, palmetto, cucumbers, hot- 

 house vegetation, and other plants, but will also eat decayed vegetation and the 

 eggs of cattle ticks. 



It may most conveniently be combated by the use of poisonous baits, especially 

 potato or bread poisoned with arseuicals and placed in locations where the sow- 

 bugs commonly congregate. Buildings may be freed of the pest by the use of 

 carbon bisulphid. 



An account is also given of the life history and habits of Porccllio lai'vis and 

 Metopoii orthus pruinosus. 



Some miscellaneous results of the work of the Bureau of Entomology, 

 IX. Notes on " punkies," F. C. Pratt (Ih H. Dept. Agr., Bur. Ent. But. 64, 

 pt. 3, pp. 23-28, figs. .'/). — Observations were made on Ceratopogon giittipeunis 

 in Virginia. This gnat causes great annoyance to man and animals in localities 

 where it occurs in large numbers. A detailed description is given of the insect 

 in its various stages. The author also discusses other related species of this 

 same genus. 



A contribution to our knowledge of the Thysanoptera of California, 

 D. MouLTON (U. S. Dept. Agr., Bur. Ent. Bui. 12, pt. 3, tech. ser., pp. VI+39-68, 

 pis. 6). — In presenting an account of the Thysanoptera of California the author 

 has found it necessary to erect a new genus Orothrips, and the genus Megalo- 

 thrips is first recognized as having representatives in this country. Thrips 

 :ilt;ick a large variety of plants sometimes causing considerable injury. The 

 r.ttack of the pear thrips was the immediate occasion of the investigation 

 reported in this paper.
