562 EXPERIMENT STATION RECORD. 



Since the life cycle of the more abundant and injurious species in these locali- 

 ties appears to be 3 years, it is pointed out that an outbreak may be loolved for 

 in 1915. Methods of control are discussed under the headings : Utilizing hogs 

 and poultry for destroying the grubs, fall plowing, rotation of crops, collecting 

 the grubs and beetles, and spraying. 



Injury by the cleoninid weevils Conorhynchus luigionii and Lixus junci 

 to sugar beets in Campania, Italy, R. Rossi (Bol. Lab. Zool. Gen. e Agr. R. 

 Scuola Hup. Agr. Portici, 6 (1912), irp. 26-Ji2, pi. 1; abs. in Internat. Inst. Agr. 

 [Rome~\, Mo. Bui. Agr. Intel, and Plant Diseases, If (1913), Xo. 2, p. 325). — 

 C. luigionii in the adult stage feeds upon the leaves of even the youngest plants 

 and in the larval form destroys the pulp of the root. The injury by L. junci is 

 caused by gnawing holes in the stalks of the plants in which the eggs are de- 

 posited. Nearly all beets thus attacked are said to die. due to being cut in two. 

 The larvse which hatch from the eggs laid along the veins of the leaves when 

 the plants are well developed excavate long galleries in the roots. 



Remedial measures consist in the killing by hand of the adults which hide 

 under stones, in crevices of the soil, and under leaves, supplemented by the 

 use of arsenicals. 



Parasites of the apple weevil (Anthonomus pomorum) in the Val di Non, 

 Austria, G. Catoni {Bol. Lab. Zool. Gen. e Agr. R. Scuola Sup. Agr. Portici, 

 6 (1912), pp. IJfS-lSO, figs. 2; abs. in Internat. Inst. Agr. [Rome], Mo. Bui. Agr. 

 Tntel. and Plant Diseases, // (1913), No. 2, p. 322).— Of 3,000 larvse taken from 

 as many apple blooms in April, 1911, 846 or 28.2 per cent are said to have been 

 parasitized, as follows : 647 by Plmpla pomorum, 63 by Meteorus ictericus. 29 by 

 Habrocytus fasciatus, and 6 by Apanteles impurus, with a noticeable preponder- 

 ance of females. Sixty-three larvae had shriveled up and the remaining 38 had 

 been destroyed by the fungus Verticillium puparum. 



Systematic notes and descriptions of some weevils of economic or bio- 

 logical importance, W. D. Pierce (Proc. U. 8. Nat. Mus., Ji2 {1912), pp. 1.55- 

 170). — This paper deals with the more important cotton weevils, namely, the 

 Mexican cotton boll weevil (Anthonomus grandis), the Peruvian cotton square- 

 weevil {A. vestitus), and the Philippine cotton flower weevil {Ecthetopyga gos- 

 sypii n. g. and n. sp.). 



The cactus weevils, of which 25 are noted, include 8 new species. Three mis- 

 cellaneous new species of biological interest are noted. 



Descriptions of new Hymen optera, III, J. C. Cr.\wford {Proc. U. 8. Nat. 

 Mus., 41 {1912), pp. 261-282, figs. 6). — Among the 21 species here described as 

 new are 8celio pulchcUus, reared from the eggs of the small plague locust 

 (Chortoicetes pusilla) in New South Wales: 8. froggatti, reared from the eggs 

 of the plague locust (C terminifera) in Queensland; 8. fulgidus, a parasite of 

 the eggs of Bachytylus australis; Chalets compsilnrce, reared from the puparia of 

 the tachinid Compsilura concinnata in Massachusetts, and also occurring in Wis- 

 consin ; and Eurytoma pyrrhocerus, said to have been reared from the codling 

 moth in New South Wales. 



Descriptions of new Hymen optera, IV, J. C. Crawford {Proc. U. 8. Nat. 

 Mus., 42 {1912), pp. 1-10, figs. 2). — The species here described as new are 

 largely reared exotic parasites. 



Descriptions of one new genus and three new species of ichneumon flies, 

 H. L. Viereck {Proc. V. 8. Nat. Mus., 41 {1912), pp. 293-295) .—The species 

 here described as new are Cceloides brunneri, reared from Dendroctonus pseudo- 

 sugw at Columbia Falls, Mont.; Megarhogas theretrce, reared from the larvae 

 of the moth Theretra celerio in Sumatra ; and Zaleptopygus oberece n. g. and 

 n. sp., from Chicago, III., a parasite of Oberea tripunctata.
