International catalogue of scientific literature. N — Zoology {Internat. 

 Cat. Sci. Lit.. '/ (1!)06), pts. J, pp. yill + V>^; -i, 1>1>. A7/ + 38.'/).— The 

 zoological literature indexed in these two parts of the international catalogue is 

 mainly that of 1904, but also includes a number of entries of literature pub- 

 lished from 1901 to 1903. As in previous parts of this catalogue, the material 

 is indexed under the author's name and also by subjects. 



Second biennial report of the commissioner of horticulture of the State 

 of California, 1905-6 (Bicn. Rpt. Comr. Uort. Cal, 2 {l'JOJ-6), pp. 557, i)Js. -i, 

 fif/s: 169). — The reports of the commissioner of horticulture for the two years 

 under consideration are given by E. Cooper (pp. 7-19), and a report of the 

 deputy commissioner is presented by E. M. Ehrhorn (pp. 20-27). 



A large part of the report is occupied with entomological matter, including an 

 outline of entomology by J. Isaac (pp. 35-1.54) ; The Coccidre of California, by 

 E. K. Carnes (pp. 1.55-222) ; Insects of the Year, by E. M. Ehrhorn (pp. 223- 

 230) ; The Codling Moth Parasite (pp. 231-235) ; The Gipsy and Brown-Tail 

 Moths (pp. 236-238) ; and An Experiment in Silk Raising, by K. Kurosawa 

 (pp. 261-270). After 2 years' experience with Caliephialtes messer as a parasite 

 of the codling moth, a numlier of fruit growers speak of the work of this para- 

 site in favorable terms, biit its practical value is not yet established beyond ques- 

 tion. Brief reports are made by the various county boards of horticultural 

 commissioners regarding insect pests, fungus diseases, and the status of fruit 

 growing (pp. 273-314). 



The proceedings of the thirty-second State fruit growers' convention, held at 

 Ilanford, Decenjber 4-7, 1906, are included in the report (pp. 315-549). At these 

 meetings popular addresses were given and articles read on various matters 

 connected with the growing of fruit. 



Sixth report of the State entomologist, W. E. Britton (Connecticut State 

 Sta. Rpt. 1906, pt. J,, pp. XII+219-306, pis. 15, figs. 13, map i).— The chief lines 

 of work undertaken by the entomologist during the year are briefly discussed. 



Considerable attention was given to nursery inspection, and a statement is 

 made regarding the condition 'of nurseries, together with an account of the 

 treatment of nursery stock by fumigation and other methods. 



A determined effort is being put forth to gain control of the gipsy moth in 

 Connecticut, which has slowly spread from Stonington, where it was first dis- 

 covered. The methods adopted in the control of the gipsy moth are similar to 

 those applied in Massachusetts. The Bureau of Entomology of this Department 

 is cooperating with the State authorities in this work. 



The entomologist has also made a study of the spiny-elm caterpillar and the 

 insects which have been found injurious to the tobacco crop in the State. These 

 include cutworms, wireworms, hornworms, flea beetles, grasshoppers, plant lice, 

 cigarette Ijeetles, etc. Notes are presented on fumigation houses and on the use 

 of hydrocyanic-acid gas and carbon bisulphid for the destruction of insects. 

 In spraying for the San Jose scale no injury was observed to buds or twigs from 

 the use of lime-sulphur mixtures. Fairly good results were also obtained from 

 the application of proprietary miscible oils, but the lime-siilphnr mixture is 

 reconnuended as being the cheapest and most effective. 



First biennial report of the "Wyoming State board of horticulture, 1905-6, 

 A. Nelson {Bien. Rpt. Wyo. Bd. Hart., 1 (1905-6), pp. 56, figs. 31).— A state- 

 ment is given of the organization of the horticultural board of Wyoming, w'ith 

 copies of the State horticultural law and the regulations of the board. Par- 

 ticular attention is devoted in this report to the requirements of the nursery law, 

 its enforcement, and benefits. Considerable time has been spent by the secre- 

 tary of the board in field work, exi)laining the purpose of the law, and awaken- 

 ing interest in the control of insect and fungous diseases.
