ENTOMOLOGY. 389 



is described in its various stages. An analytical table is given for tbe identification 

 of species. As a rule, only those species are admitted which belong to the eastern 

 United States. 



A preliminary catalogue of the described species of the family Fulgoridae 

 of North America north of Mexico, 0. II. Swezey (Ohio Dept. Agr., Div. Nursery 

 and Orchard Inspection Bui. 3, pp. 48). — In this catalogue an attempt has been made 

 to include all species of the family which have been reported in literature accessible 

 to the author. Notes are given on the distribution and synonymy of each species. 



Results of a biological study of South American white ants, F. Silvestki 

 (Mem. by Rev. Soc. dent. "Antmio Alzate," 18 (1903), No. 7-8, pp. 353-378).— The 

 various kinds of individuals observed in colonies of white ants with notes on the 

 nesting habits and other matters relating to the biology of different species of these 

 insects. 



The introduction of the fruit-fiy parasite, G. Compere (Jour. Dept. Agr. West. 

 Australia, 10 (1904), No. 2, pp. 68-72). — The author made a trip to Brazil for the pur- 

 pose of seeking insect parasites of Ceratitis capitata. During this journey notes were 

 made on the prevalence and injurious effects of the fruit fly. A species of beetle was 

 obtained belonging to the family Staph ylinidae which attacks the fruit fly and con- 

 siderable success was had in transmitting these predaceous insects to England. The 

 beetle attacks the fruit flies only in the maggot condition, but appeared to destroy a 

 large percentage of these pests in Brazil. 



Notes on Ixodidee, L. G. Neumann (Arch. Parasit., 8 (1904), No. 3, pp. 444-464, 

 figs. 2). — The genera of this family are carefully diagnosed and detailed descriptions 

 are given of the various species, together with notes on their habits and life history. 



Life history of Lycaena argiades, F. W. Frohawk (Entomologist, 37 (1904), No. 

 497, pp. 245-249). — A description is given of the egg, various larval stages, and pupa 

 of this butterfly, with other notes on its habits and life history. 



When to spray, A. E. Stene ( Rhode Island Sta. Bid. 100, pp. 121-148, pis. 3, 

 figs. 3). — In this bulletin the author's purpose was to present a general account of 

 the subject of spraying, together with a tabular statement of the periods when spray- 

 ing is most effective for various insect and fungus diseases, formulas for the prepara- 

 tion of fungicides and insecticides, and specific directions for the control of the San 

 Jose scale. 



A new general insecticide, H. M. Lefroy (Jour. British Honduras Soc. Agr. and 

 Com., 1 (1903), No. 1, p. 16). — The author describes an insecticide having the follow- 

 ing formula: 10 lbs. whale-oil soap, 5| pts. crude Barbados oil, 4 oz. Naphthalene. 

 This emulsion is effective against plant lice, mealy bugs, scale insects, ticks, and 

 other pests on domesticated animals. 



The method of applying Paris green, VV. B. Seabrook (Bui. Dept. Agr. 

 Jamaica, 2 (1904), No. 7, pp. 159, 160).— The author states that Paris green may be 

 applied to cotton in a dry, unmixed form by placing a small quantity of it in a bag 

 composed of material known as American gray sheeting. The bag is attached to a 

 staff and is gently rapped with a stick while in position over the cotton plant. No 

 injury was caused to the cotton by this method of application. 



Mosquitoes in Hawaii, D. L. Van Dine (Hawaii Sta. Bui. 6, pp. 30, figs. 12). — 

 Mosquitoes were not known in Hawaii previous to 1826, at which date Qulex pipiens 

 was introduced. Within recent years two other species, Stegomyia fasciata and S. Scu- 

 tellaria, have also been introduced. The most abundant species is Qulex pipiens. 

 Notes are given on the habits, life history, and breeding places of all three species. 

 A number of fish are known to feed upon the larval mosquitoes, goldfish being con- 

 sidered the most important enemy of the mosquitoes. While it is believed that com- 

 plete extermination of mosquitoes is impossible, it is urged that strong efforts be 

 made to reduce them as far as possible by drainage of pools and the use of kerosene.
