764 EXPERIMENT STATION RECORD. 



A synonymic index-catalogue of spiders of North, Central and South 

 America with all adjacent islands, Greenland, Bermuda, West Indies, Terra 

 del Fuego, Galapagos, etc., A. Petrunkevitch (Bui. Amer. Mus. Nat. Hist., 29 

 (1911), pp. V+791).—This work is divided into 3 parts. Part 1 (pp. 11-39) 

 consists of a bibliography of 533 titles; part 2 (pp. 41-720) of the catalogue 

 proper, with complete synonymy, references to publications, years, volumes, 

 pages, and figures, as well as to the localities indicated by different authors; 

 and part 3 (pp. 721-790) of an alphabetic list of synonyms. 



A handbook of the tsetse flies (genus Glossina), E. E. Austen (London, 

 1911, pp. X+110, pis. 10, figs. 2.'t; rev. in Sleeping Sickness Bur. [London] Bui., 

 S (1911), No. 27, pp. 223-225). — This handbook replaces the monograph by the 

 author, previously noted (E. S. R., 15, p. 621), now out of print, and brings the 

 subject up to date. Fourteen species are described of which 2 are new to 

 science, namely, G. fuscipleuris from the northeast of Congo Free State, and 

 O. medicoriim from West Africa. 



A summary of its bionoimics, so far as known, is given under the heading of 

 each species, G. pal pal is excepted. 



Supplemental studies of trypanosomes, F. K. Kleine and M. Taute (Arb. K. 

 Gsndhtsamt., 31 (1911), No. 2, pp. 321-316, pis. 5, figs. 5; ahs. in Sleeping Sick- 

 ness Bur. [London] Bui, 3 (1911), No. 2, pp. 165-175). — Investigations of the 

 biology of trypanosomes and tsetse flies and the manner of transmission of the 

 former, conducted in continuation of those by Koch, Beck, and Kleine, previ- 

 ously noted (E. S. R., 22, p. 684), are reported. 

 A bibliography of 61 titles is appended. 



Spraying of woodland and shade trees, L. H. Worthley (Jour. Econ. Ent., 4 

 (1911), No. 2, pp. 188-193, pis. 3). — The data here presented are based on the 

 experiments and experience of the gipsy-moth commission in Massachusetts. 



Spraying apparatus for scale insects, E. L. Worsham (Jour. Econ. Ent., 4 

 (1911), No. 2, pp. 193-199). — The author considers apparatus and accessories, 

 particularly with reference to their use in controlling the Coccidse. 



The California insecticide law, C. W. Woodworth (Calif ornia Sta. Circ. 65, 

 pp. 23). — The text of the California insecticide act of 1911 is here presented 

 and discussed. This law requires manufacturers, importers, and dealers in 

 insecticides and fungicides to obtain, on or before the first day of July of each 

 year, beginning in 1911, a certificate of registration authorizing the sale of 

 insecticides in the State. Insecticides and fungicides must be labeled to show 

 (1) the name, brand, and trade-mark if there be any, (2) the name and address 

 of the manufacturer, importer, or dealer, (3) the place of manufacture, (4) the 

 chemical analysis, and (5) the registry number. The rules and regulations 

 adopted by the United States Government for the enforcement of the federal 

 insecticidf- act of 1910, also presented, are to be followed in holding private 

 hearings. 



Directions are given for the labeling of the various insecticides and fun- 

 gicides. 



Insect powder (V. S. Dept. Agr., Insecticide Decision 1, pp. 3). — The Insecti- 

 cide and Fungicide Board here rules that the term " insect powder " when 

 used without qualification means an insecticide made from the powdered 

 flower heads of certain species of chrysanthemums, namely, Chrysanthemum 

 (Pyrethrum) cineraricefolium, C. (Pyrethrum) roseum, and C. marshallii 

 (Pyrethrum carneum). In designating a mixture of powdered flowers and 

 stems, the term " insect powder " may be used, provided this is immediately 

 qualified by word or phrase so as to indicate clearly the nature of the article. 

 Investigations to determine the precise value of the powdered stems are stated 

 to be under way. The terms " Pyrethrum " and " Pyrethrum powder " are, 

 when applied to insecticides, deemed synonymous with " insect powder."
