 A new scaraba;id pest, a description of which under the name Odontiia punc- 

 licoUis by Broun is appended, is siiid to be the source of considerable loss in 

 the seedling beds at the state forest nurseries at AVhakarewarewa through the 

 destruction of the roots of the young trees by the larvie. 



The life history and bionomics of Cryptorbynchus lapatbi, F. Scheidteb 

 {Natnrw. Ztschr. Forst u. Landio., 11 {1913), No. 5-6, pp. 279-300, figs. 6).— A 

 report of the biological studies of the poplar and willow borer. 



On the biology of Tropinota turanica, X. N. Troitzki' (Reprint from Jour. 

 Agr. Turkest. [Tashkerid], No. 6 {1913), pp. 18, figs. 2; abs. in Rev. Appl. Ent., 

 1 {1913), Ser. A, No. 11, pp. Jf37, 438). — This cetouiid beetle is a prominent and 

 regular pest of orchards in Tashkend, injuring the blossoms of apricots, cher- 

 ries, thorns, apples, pears, strawberries, etc. It attacks only the unfertilized 

 blossoms, eating away the ovaries, pistils, and stamens, but doing no great 

 damage to the petals. The injury is done only by the perfect insect, the eggs 

 being laid in the fields, where the larvse feed on roots of various plants. 



On an egg-eating parasite of Rhynchites auratus, N. N. Troitzky {Reprint 

 from Jour. Agr. Turkcst. [Tdshkcnd], No. 5 {1913); ahs. in Rev. Appl. Ent., 

 1 {1913), Ser. A, No. 11, pp. Jt36, Jf37).—A chalcidid, apparently belonging to the 

 genus Oophthora, is said to have parasitized 88 per cent of the eggs of this 

 weevil in Tashkend in 1912. 



Contributions to our knowledge of the British Braconidae. — I, Mete- 

 oridse, G. T. Lyle {Entomologist, 1ft {1914), Nos. 610, pp. 73-77, pi. 1; 611, pp. 

 119-125). — The author states that he knows of no instance of a meteorid 

 hibernating in the perfect state. With several species the winter is passed 

 within the body of the host, either as an ovum or young larva, and with a few 

 others as a larva within the cocoon. 



Life histories of Indian insects. — IV, Hymenoptera, G. R. Dutt {Mem. 

 Dept. Agr. India, Ent. Ser.. 4 (1912), No. 4, PP- 1S3-267, pis. 4, figs. 22).— This 

 part (E. S. R., 26, p. 654) deals with the life histories of various species of 

 Hymenoptera, including species of the families Mutillidse, Thynnidae, Scoliidse, 

 PompilidiB, Sphegidae, Eumenidse, Apidae, and Formicidse. 



Spider enemies of bees, R. J. Levandovsky {Russ. Pchelovod. Listok [Mos- 

 cow], 1913, Nov., pp. 378-387; aU. in Rev. Appl. Ent., 2 {1914), Ser. A, No. 2, 

 pp. 64, 65). — A report of personal observations with a list of the spiders 

 implicated. 



Bryobia praetiosa, I. Tragardh {Meddel. Centralanst. Forsoksv. Jordhruk- 

 somrddet, No. 17 {1914), PP- 24, figs. 7). — A review of the literature leads the 

 author to conclude that the different species described under the names of 

 prcEtiosa, speciosa, nobilis, gloriosa, riMs, and pratensis must be referred to 

 praetiosa K., being mere variations and different instars of that species. This 

 pest is said to be found all over Europe, southward as far as Egypt, northward 

 to the arctic regions, and in the United States. 



Transmission of Trypanosoma cruzi by Rhipicephalus sanguineus, A. 

 Neiva {Abs. in Bui. Inst. Pasteur, 12 {1914), No. 1, pp. 45, 46).— Five male ticks 

 {R. sanguineus), detached after death from a dog that had been inoculated 

 with T. cruzi and was also infected with Piroplasma vitali, were placed upon a 

 healthy dog and 19 days later the latter dog was found to be infected with 

 2'. cruzi.
