taut wounds in the collars of the plant, but soon burrow deeper In the soil and 

 attack the roots. The depth to which they burrow varies from the surface 

 to 20 in., according to the amount of moisture in the soil, etc. 



On sorae Curculionidse living in bamboo stems, A. da Costa Lima (Mem. 

 Inst. Osxmldo Cruz, 6 {19 W, No. S, pp. 224-230, pis. 2).— In this second paper 

 (E. S. R., 32, p. 352) the author deals at some length with Astyage lineigera, 

 a curculionid beetle attacking bamboo in Brazil. The larvae and nymphs of 

 this species are said to be attacked by fiacherie, which is responsible for a 

 large mortality. Other species reared from bamboo stems at Joinville are 

 Periderceus granellus, Dionychus parallelogramus, and Erethistes lateralis 

 catltarinensis. 



Inquiline bumblebees in British Columbia, F. W. L. Sladen (Canad. Ent., 

 47 (1915), No. 3, p. 8-i).— -The author records the collection of Psithyrus insularis 

 and P. cotisultus in a nest of Bomhus flarifrons at Agassiz, British Columbia, 

 upon which they are apparently parasitic. 



Description of a new seed chalcid from spruce, S. A. Rohwer (Canad. Ent., 

 41 {1915), No. 8, pp. 97, 98, fig. l).—k. chalcidid reared from the seeds of 

 Engelmauu spruce {Picea engehnanni), the Sitka spruce (P. sitchensis), and 

 the Colorado blue spruce (P. parryana) in Colorado, and also received from 

 California, is described as Mcgastigmus picece. 



Asparagus beetle egg parasite, F. A. Johnston {U. S. Dept. Agr., Jour Agr. 

 Research, 4 (1915), No. 4, pp. 303-313, pi. i).— This report of studies of 

 Tetrastichus asparagi includes a summary of those of Russell and Johnston, 

 previously noted (E. S. R., 28, p. 858). 



Following a brief introduction, descriptions are given of the several stages 

 of the parasite, its distribution, and feeding habits. Under the heading of 

 laboratory experiments, a brief account is given of methods used in rearing 

 the parasite and a tabulation of records of the length of life of the adult in 

 confinement. There appear to be three generations a year on Long Island, 

 where it apparently hibernates as a full-grown larva in the cell of its host in 

 the ground. In rearing experiments from 1 to 10 larvae of the parasite were 

 found in a single beetle cell. Attempted parasitism of the eggs and young 

 larvte of the potato beetle and eggs of the elm-leaf beetle failed. From 7 to 

 11 days were found to be passed in the pupal stage. 



A list of 7 titles is given of literature cited. 



Notes on the life history of a species of wasplike parasites of the genus 

 Leptomastix, parasitic on the mealy bug, H. L. Viereck (Mo. Bui. Com. 

 Hort. Cal., 4 (1915), No. 4, pp. 208-211, fi,gs. 3).— A chalcidid belonging to the 

 genus Leptomastix which appears to be new to science was collected by the 

 author on Pseudococcus citri at Palermo, Sicily, in June, 1914. It has since 

 been introduced into California, where it has been successfully reared and bids 

 fair to become an important aid In the control of the citrus mealy bug. 



Studies of its life history show that from 21 to 49 days are required to pass 

 from the laying of the egg to the emergence of the adult. From 3 to 6 days are 

 passed in the egg stage, from 8 to 25 days in the larval stage, and from 10 to 

 18 days in the pupal stage. 



Journey in Eritrea in search of olive fly parasites, F. Silvestbi (Bol. Lab. 

 Zool. Gen. e Agr. R. Scuola Sup. Agr. Portici, 9 (1914), pp. 186-226, figs. 24; 

 ahs. in Rev. Appl. Ent., 3 (1915), Ser. A, No. 4, p. 173). — As a result of a trip to 

 Eritrea during August and September, 1914, 14 parasites of the olive fly (Dacus 

 olea;) v/ere secured. Descriptions and biological notes are given. 



Parasitic Hymenoptera new to the fauna of Turkestan, N. Kokuev (Rusa. 

 Ent. Ohozr., 13 (1913), No. 3-4, pp. 513, 5i^).— The author describes Hahrohracon
