360 EXPERIMENT STATION EECOED. 



Eradication of ticks by the starvation method, H. B. Laws and B. Man- 

 ning (Agr. Jour. Cape Good Hope, 37 (1910), No. 1, pp. 9-17; Natal Agr. Jour., 

 15 (1910), No. 2, pp. 196-206; abs. in Vet. Jour., 66 (1910), No. 1,23, pp. 

 549-553). — From the experiments reported the authors conclude that so long 

 as game have access to an inclosed area total eradication of the several species 

 concerned will be Impossible. Periodic dipping in an efficient dip at intervals 

 of not moi'e than 14 days is considered more effective in the extermination of 

 ticks of all kinds than starvation, and at the same time has the advantage that 

 it can be carried on in conjunction with the ordinary farm work. 



The relationship of ticks and animal disease, II. W. Jack (Rhodesia Agr. 

 Jour., 7 (1910), No. 6, pp. I.'f78-U97, pis. 3).— A brief summarized accoimt. 



The insects injurious or beneficial to sugar cane in Formosa, S. Matsu- 

 MUEA (Ztschr. Wiss. InscMcubioL, 6 (1910). Nos. 3, pp. lOl-lOJ,; 4, pp. 136- 

 139). — This gives a list of 125 injurious and 41 beneficial species collected by 

 the author in Formosa. 



The insect galls of Michigan, M. T. Cook (Mich. Geol. and Biol. Surv. Pub. 

 1, Biol. Her. 1, 1910, pp. 23-33). — The host plants upon which the 59 species of 

 galls here mentioned occur are distributed among 14 genera of 11 families of 9 

 orders. 



Note on two new insecticidal agents, R. H. Pettit (Rpt. Mich. Acad. Set., 

 10 (1908), pp. 159, 160). — A remedy devised for use against Cimex lectularius, 

 and another for use against ants in houses, are described. 



The Mantispidae of Japan, T. Miyake (Jour. Col. Agr. Imp. Univ. Tokyo, 2 

 (1910), No. 3, pp. 213-221, pi. i).— All of the 5 species known from Japan be- 

 long to the genus Mantispa. Three of these are new to science and 1 is new 

 to Japan. 



A further contribution towards the knowledge of the Panorpidae of Japan, 

 T. Miyake (Jour. Col. Agr. Imp. Univ. Tokyo, 2 (1910), No. 3, pp. 183-205, pi. 1, 

 fig. 1). — Nine species are here described as new, making a total of 36 species of 

 Panorpidifi known to occur in Japan. 



Some insects injurious to truck crops (U. 8. Dept. Agr., Bur, Ent. Bui. 82, 

 pt. 6, pp. 67-84, figs. 5). — This contains two papers. 



Notes on the cucumber beetles, F. H. Chittenden (pp. 67-75). — This paper 

 presents notes on 5 species of beetles of the genus Diabrotica. The saddled 

 cucumber beetle (D. connexa) has been found to attack cucurbitaceous plants 

 at Corpus Christi, Tex., and has been commonly met with in western Texas. 

 The painted cucumber beetle (D. picticoniis) has been found at San Antonio, 

 Tex., attacking okra, beets, vetch, horse beans, squash, and cotton. The belted 

 cucumber beetle (D. baltcata) attacks wheat in Mexico and occurs in great 

 numbers on beans, corn, and okra, especially in the blossoms, and on cucumbers 

 and other plants at several points in southern Texas. The western 12-spotted 

 cucumber beetle (D. soror) is recorded from California as a source of injury 

 to beets, melon, cucumber, squash, beans, corn, and other vegetables; the beetle 

 is described and notes are given on its life history and habits with records of 

 injury. The western striped cucumber beetle (D. trivittata) which is common 

 throughout the State of California and extending into Oregon is said to injure 

 beans, cucumbers, squash, and the silk of corn in the vicinity of Salem. Oreg., 

 and melons at Imperial Junction, Cal. 



Biologic notes on species of Diabrotica in southern Texas, H. O. Marsh (pp. 

 76-84). — Four species are considered in this paper. D. picticornis was observed 

 to attack the blossoms and foliage of cucurbits at Brownsville, Tex., in May 

 and June of 1908. D. balteata is stated to be active during the year in southern 

 Texas and by far the most injurious and common Diabrotica in the lower Rio 

 Grande valley. Notes are given on its food plants, character of injury, occur-
