564 EXPERIMENT STATION KECOED. 



author states that from a commercial standpoint it is not often a very important 

 factor in the control of the scale. 



In describing its life history and habits, it is stated that this chalcidid may 

 reproduce partheuogenetically. In midsummer the egg period was found to be 

 5 days, the larval 16, the pupal 15, and the adult 9 days, a total of 45 days for 

 the life cycle from the egg to the death of the adult. 



Two new species of African parasitic Hymenoptera, J. C. Crawford ( Canad. 

 Ent., 42 {1910), No. 7, jip. 222, 223). — The author describes Scelio hoivardi, 

 reared from the eggs of Cyrtacanthacris septenifasciata, and Tctrastichiis ijcri- 

 planetce, from the eggs of Periplaneta americana, together with numerous speci- 

 mens of T. hagenowii, as new. 



Notes and descriptions of North. American parasitic Hymenoptera, IX, 

 C. T. Brues {Bui. ^Yis. Nat. Hist. Soc, [n. ser.], S {1910). No. 2, pp. 67-85, 

 figs. 13). — The author describes 13 species as new, one of which (Cheiropachys 

 obscuripes) was reared from a peach bark beetle (probably Phlwotrihtm limi- 

 naris) at Douglas, Mich. 



First introduction of the Blastopliaga, W. T. Swingle and G. P. Rixford 

 {Cal. Cult., 35 {1910), No. 26, pp. 659, 661,, 665).— The authors present evidence 

 to show that Blastophaga grossorum has been established and breeding in the 

 San Joaquin Valley for over 40 years. 



The plain facts of fig' wasp history, G. C. Roeding {Cal. Cult., 35 {1910), 

 No. 26, pp. 659, 665). — The account noted above is reviewed. The author con- 

 cludes " that there is absolutely no foundation for the claims which have been 

 made concerning the early introduction of the Blastophaga into California." 



A phytoptid gall of Artemisia calif ornica, H. V. M. Hall {Pomona Jour. 

 Ent., 2 {1910), No. 3, pp. 2S0, 281, fig. 1). — Eriophyes calif ornica, which causes 

 a white or pinkish swelling on one side of the leaf of A. californica, is described 

 as new. It is said to be very abundant at Claremont, Cal. 



Note on the finding of Hsemaphysalis punctata at Winnipeg, Manitoba, 

 S. Hadwen {Canad. Ent., 42 {1910), No. 7, pp. 221, 222, pi. 1).—H. punctata, a 

 tick common in England and certain European countries, is recorded from 

 North America for the first time, the specimens having been collected from 

 cattle at Winnipeg, Manitoba. 



The importance of this discovery lies in the possibility of its transmitting 

 piroplasmosis of cattle in Canada as it has been shown to do in England. 



Ticks and practical measures for their prevention, A. Fredholm {Proc. 

 Agr. Soc. Trinidad and Tohago, 10 {1910), No. 7, pp. 239-292) .—This article is 

 largely based on the publications of R. Newstead and H. H. Cousins, previously 

 noted (E. S. R., 22, p. 55S; 23, p. 76G). 



It is said that ticks are not so gi-eat a pest in Trinidad as in Jamaica, this 

 being due to the fact that the cattle industry is not so far advanced. Texas 

 fever has been introduced into Trinidad on a few occasions but has never 

 assumed epidemic proportions. " Energetic measui'es have been taken at once 

 to suppress it and they have been successful owing, probably, in no small 

 degree to the fact that the cattle industry is not extensive." 



An American intermediate host for Hymenolepis diminuta, W. S. Nicker- 

 SON {Abs. in Science, n. ser., 33 {1911), No. 8-'i2, p. 271). — The author's experi- 

 ments show that in America at least 2 different genera of Myriapoda may act 

 as intermediate hosts for 11. dinvinuta, the common tapeworm of the rat, which 

 is also an occasional human parasite. It has previously been shown in 

 Europe that its cercocystis stage may be passed in several insects, namely, the 

 meal moth and its larva (Asopia), an earwig (Anisolabis), and beetles (Akis 

 and Scaurus), Asopia being the form that commonly serves as an intermediate 

 host.
