of California, and many of them are of considerable economic importance. A general 

 account is given of the external anatomy, life history, and habits of this group, 

 together with analytical keys and detailed descriptions of the species. 



The Mexican cotton-boll weevil, W. Newell ( Georgia State Bd. hint. Bui. 12, 

 pp. 29, figs. U) . — The cotton-boll weevil is described in its various stages, and notes 

 are given on various other phases of the weevil problem, such as the rate of increase 

 and destructiveness of the pest, artificial remedies, the relation of birds to the boll 

 weevil, insects frequently mistaken for this pest, and the quarantine law of < reorgia 

 regarding the boll weevil. 



The cabbage worm, M. L. Merritt (Iowa Agr., ■', (1904), No. .?, pp. 86, 87). — 

 Notes are given on the habits and life history of Pieris rap:*. In combating this 

 insect a dust spray of Paris green at the rate of 1 part to 25 parts air-slaked lime is 

 recommended. A satisfactory liquid insecticide may be prepared so as to contain 5 

 lbs. pulverized resin, 1 lb. concentrated lye, 1 pt. fish oil, and 5 gal. water. This 

 stock material after boiling for 2 hours is to be diluted at the rate of 1 gal. per 16 

 gal. of water. 



The discovery of the native home of the San Jose scale in Eastern China 

 and the importation of its natural enemy, ('. L. Marlatt [Pop. Sci. Mo., 65 

 (1904), No. 4, pp. 306-317, fiys. 8). — A popular account is given of the author's 

 travels in China and Japan, together with notes on the agency of Chilocorus s'<milis in 

 controlling the San Jose scale. 



The morphology, classification, and systematic position of Anoplura with 

 notes on insect orders, G. Enderleix (Zoo/. Anz., 28 (1904), No. 4, pp. 121-147, 

 figs. 15). — Notes are given on the anatomy of the various parts of the body of 

 Anoplura with especial reference to the importance of these characters in the scien- 

 tific system of classification. An analytical table is given to assist in the identifica- 

 tion of various families and genera of lice, a number of which are described as new. 



The bearing of these studies upon the general classification of the orders of insects 

 is indicated. In this connection attention is called tor the great confusion which has 

 resulted from the continual introduction of new names for insect orders. 



List of the Tabanidse (horseflies) of North Carolina, C. S. Brimley and 

 F. Sherman, Jr. (Ent. News, 15 (1904), No. 8, pp. 270-275).— A list of horseflies 

 reported in this paper is based on collections made by the authors during the past 2 

 years and covers species captured at various altitudes from sea level to 4,000 ft. 



The habits of adult mosquitoes of the genus Anopheles in relation to 

 hydraulic engineering, E. Pekrone (Atti Soc. Studi Malaria, ■'< 1 1904), pp. 49-64). — 

 The breeding habits of mosquitoes are briefly noted, with especial reference to artifi- 

 cial waterways as breeding places for mosquitoes and as means of draining such 

 breeding places. The beneficial effects of draining have been noted in a number of 

 localities. 



An acarid parasite of Anopheles, II. Gros (Compt. Rend. Soc Biol. [Pans], 56 

 (1904), No. 2, pp. 56, 57). — Specimens of Anojtheles maculipennis were captured with 

 a small parasite attached to the body. The parasite possesses a round, ill-defined 

 form of a reddish or violet color. Notes are given on the structure of the organism, 

 which may prove to be a true parasite, oris, perhaps, more correctly considered a 

 commensal organism. 



Acarid parasites of Anopheles, Esmond and Etienne Sergent (Compt. Rend. 

 Soc. Biol. [Paris], 56 (1904), No. 3, pp. 100-102).— It was found that the acarid para- 

 sites observed attached to the bodies of Anopheles algeriensis may become transferred 

 to ^4. maculipennis if the 2 species are kept confined in the same cage. 



A new species of tsetse fly (Glossinadecorsei) from Central Africa, E. Brumpt 

 (Compt. Rend. Soc. Biol. [Pen-is], 56 (1904), No. 13, pp. 628-630).— This species is 

 described as new and brief notes are given on its habits and life history. The bite of
