Report of the entomologists, C'. IF. and II. T. Fiohnai.d {M((sKiirhiisiils Sla. h'j,/. 

 lUOJ, i>i>. 4-'>-47). — During tlie year considerable attention was given to melhod.s (if 

 eond)ating San Jose scale, as required by the nursery ins])ection law ot the State. 

 The most important injurious insects during the year were brown-tail moth, gypsy 

 moth, San Jose scale, elm-leaf beetle, etc. 



Entomological department, K. A. Cooley [Montana SUi. Rpt. li)02, pp. 80-87). — 

 The author presents a list of the more important injurious insects which have been 

 foun<l within the State. Brief notes are also })resented on mosquitoes, grasshoppers, 

 plant lii-e, flea-beetles, cottonwood-leaf beetle, cucumber flea-beetle, mealy bugs, 

 and ants. 



Report of the entomologist, J. B. SMrrir {New Jer.'iey Stas. Rpt. 1903, pp. 423- 593, 

 })'x. 17,Ji(/-f. 11). — The author discusses miscellaneous outbreaks of injurious insects 

 during tlie year 1902, including plant lice, fall webworm, strawberry weevil, rose 

 beetles, grain insects, periodical cicada, and oak pruner. Brief mention is made of 

 the present status of imported INIantidye, cabbage insects, San Jose scale, and Chinese 

 ladybirds. During the season considerable work was done in the way of inspecting 

 irchards and nurseries. Insecticide experiments were carried on in the entomolo- 

 gist's experimental orchard. Black insecticide soap, used at the rate of 1 lb. in 6 or 

 7 gals, of water, was of little use as a remedy for San Jose scale. Agricultural soap 

 also gave unsatisfactory results, while Calcothion proved quite effective. Brief 

 extracts are given from the crop bulletin for the year. The author discusses the 

 appearance of periodical cicada in New Jersey in 1902, together with notes on its 

 distribution, life history, injuries, and measures for repressing it. 



General directions are given for fumigating trees, greenhouses, small fruits, and 

 infested buildings, with notes on the advantages and limitations of the method of 

 fumigation. The author discusses also the present distribution of the Chinese lady- 

 bird in New Jersey, and states that while no new experiments have been made with 

 crude petroleum at the station, numerous satisfactory reports have been received 

 from fruit growers who have used this remedy. 



The author spent consideral)le time in the investigation of the niost|uito luiisance. 

 Notes are given on the habits and life history of the mosquitoes of New Jersey, with 

 special reference to the conditions which are favorable or unfavorable to their spread. 

 Mention is made of fish and other natural enemies of mosquitoes. The marshes 

 around various cities were studied for the purpose of locating breeding grounds of 

 mosquitoes and determining methods of combating the pest. It is urged that drain- 

 age or ditching is the method by which extensive lireeding areas of moscpiitoes can 

 be rendered harmless. 



H. P. Johnson presents a report on certain mosquitoes of New Jersey with special 

 reference to malaria. The species studied were Cvle.v pnngemf, ('. .wllicilana, Anoplie- 

 les punctipe^ini!^, A. maculipennis, and other less important forms. Notes are given 

 on meteorological conditions, breeding habits, and natural enemies of mostjuitoes, 

 the duration of larval and adult life, the relative proportion of the sexes, food of the 

 larva', biting habits, and the agency of mosquitoes in the transmission of malaria. 



Report of the State entomologist, J. B. Smith {Neiv Jer.seji Shtlc Ed. Agr. Rpt. 

 I'MJ, pp. 101-108). — Reference is made to the introduction into this country of Chilo- 

 conis siinills, and the effect of this and related species of ladybirds upon San Jose 

 scale. Notes are given on the work of State inspection and relationship between the 

 duties of inspection officers and those of investigators. Mention is also made of the 

 injury caused by sinuate pear jjorer. 



Eighteenth report of the State entomologist on injurious and other insects 

 of the State of New York, E. P. Felt {Xew Yurk Slate Mus. But., 1903, \o. 64, pp. 

 89-193, pis. 6,jjg>^. 2'). — Notes are given on the habits, life history, and means of 

 combating brown-tail moth. This insist is believed not to occur in the State. The 

 carrot-rust fly (Pnila ro^w) has been found injuring celery as well as carrots. Notes
