The life cycle of Laclinosterna tristis, J. J. Davts {Jour. Econ. Enl., 6 

 ilillS), xA'o. 2, pp. 276-278). — It is stntwl that up to the present time the life 

 cycle of but oue species of Lachnosteraa (L. arcuata) has been worljed out and 

 recorded in literature. This was studied by Pergande (E. S. R., 11, p. 365) 

 who found it to have a life cycle of practically 3 years, at Washington, D. C, 

 it remaining in the grub stage parts of 3 years, and the total larval period being 

 slightly over 25 months. L. tristis has been found by the author to have a life 

 cycle of only 2 years. 



Some experiments with Roentgen rays upon the cigarette beetle, Lasio- 

 derma serricome, A. C. Morgan and G. A. Runner (Jour. Econ. Ent., 6 

 (J91S). No. 2, pp. 226-2S0). — This is a report of tests made of an X-ray machine 

 built for sterilizing cigars upon a commercial scale. The results show that 

 neither the " hard " nor the " soft " rays used in the test gave any indications 

 of affecting any of the stages of the cigarette beetle. 



An enemy of the cigarette beetle, A. C. Morgan (Proc. Ent. Soc. Wash., 15 

 (1913), No. 2, p. 89). — The larvae of the clerid beetle Thaneroclerus girodi have 

 been found by the author to prey upon the larvae and pupte of Lasioderma serri- 

 come at Key West, Fla.; the adults are predaceous upon all stages of this pest. 



Phytonomus meles, E. P. Felt (Jour. Econ. Ent., 6 (1913), No. 2, pp. 283, 

 28J/). — This weevil appears to have been recently introduced into this country, 

 it having been first collected in New Yorli State in 1907. It was reared from 

 clover collected in the vicinity of Albany in 190S, and was observed during the 

 latter part of May, 1912, to be very abundant on red clover at New Baltimore. 

 N. Y.. feeding upon the foliage and causing some Injury. 



The Siricidae of North America, J. C. Bradley (Jour. Ent. and Zool., 5 

 (1913), No. 1, pp. 1-30, pis. 5). — This is a brief preliminary account of the 

 horntails. 



New Ichneumonoidea parasitic on leaf-mining Diptera, A. B. Gahan 

 (Canad. Ent., .'f5 (1913), No. 5, pp. lJi5-154)-—Opius utahensis, reared from 

 Agromyza parvicornis at Salt Lake, Utah; 0. suturalis and O. aridis, both 

 reared from A. pusilla, at Tempe, Ariz. ; O. trxinclpes, reared from A. pusilla, 

 at Laljeland, Fla. ; 0. succineus, reared from Agromyza sp., mining leaves of 

 Panicum, at Lafayette, Ind. ; Dacnusa scaptomyzce, reared from Scaptomyza 

 flaveola, at College Parlv, Md. ; and D. agromyzce, reared from A. ang^ulata, at 

 Lafayette, Ind., are described as new to science. 



A new genus and one new species of Chalcidoidea, A. B. Gahan (Canad. 

 Ent., Ji5 (1913), No. 6, pp. 178-182). — CoelopistJioldea cladiae n. g. and n. sp. 

 was reared at Upper Marlboro, Md., from the cocoons of the sawfiy Cladius 

 pectin icornix occurring on rose bushes. 



Scutellista cyanea, bred from Phenacoccus artemisiae, E. O. Essio (Jour. 

 Ent. and Zoo!., 5 (1913), No. 1, pp. 55). — This is said to be the first record of 

 the rearing of 8. cyanea from this type of coccid. 



An undescribed hymenopterous parasite of the house fly, C. H. Richardson, 

 Jr. (Psyche, 20 (1913). No. 1, pp. 38, 39, pi. 1).—A new pteromalid, reared from 

 Musca domestica at Forest Hills, Mass., and from Btomoxys calcitrans at 

 Dallas, Tex., is described under the name of Spalangia muscidarum. 



New Peruvian parasites from Hemichionaspis minor, E. W. Rust (Ent. 

 News, 2i (1913), No. //, pp. 160-165). — Prospaltella peruviana, reared from H. 

 minor; Signiphora lutea, reared from H. minor and Pseudao-nidia sp. on vari- 

 ous hosts, principally cotton and citrus ; and Neosigniphora nigra, reared from 

 H. minor on cotton, are described as new to science. 



Additional notes on the biology of the Rocky Mountain spotted fever tick, 

 P. C. BiSHOPP and W. V. King (Jour. Econ. Ent., 6 (1913), No. 2, pp. 200- 

 211). — The notes here presented are supplementary to the accounts previou-sly
