Dark currant fruit fly in California, Rhagoletis ribicola, H. H. P. Severin 

 (Mo. Bui. Com. Hort. Cal., 6 (1917), No. 7, pp. 258-260. fig. i).— The collection 

 in California of a specimen of the dark currant fly (R. ribicola), which has 

 been reported by Piper and Doane (E. S. R., 10, p. 869) to be of considerable 

 economic importance in the State of Washington, is recorded. 



The melon fly in Hawaii, E. A. Back and C. E. Pembekton (U. S. Dept. Agr. 

 Btil. 491 (1917), pp. 64, pis. 24, figs. iO).— This is a summary of the present 

 status of the knowledge of (Dacus) Bactrocera cucurhitoe, based upon a re- 

 view of the literature and the authors' investigations conducted during a period 

 of several years; and including the studies previously noted (E. S. R., 32, p. 452). 



An annotated bibliography of 51 titles is appended. 



The root maggot pest, E. B. Stookey (^ya8hington Sta., West. Wash. Sta. 

 Mo. Bui., 5 (1917), No. S, pp. S2-S4, figs. ^).— The root maggot is said to be very 

 common throughout western Washington and to do considerable damage each 

 year to various cruciferous plants and also to onions. The work of the year 

 was largely in connection with the kale crop. Previous erperimeuts indicate 

 " that to use fall-seeded kale for early transplanting In the spring is a good 

 practice, both from the standpoint of size and freedom from root maggot ; that 

 transplanted plants should be protected by tarred felt pads ; and thiit the later 

 seedings and transplautings are usually less damnged by root maggot than 

 those from early spring seeding. 



" The average loss the past year on transplanted kale protected by tarred 

 felt pads varied from 8.65 to 12.1 per cent, as against averages of 28.36 to 45.9 

 per cent loss where no pads were used. The average loss from transplanted 

 fall-seeded plants was 28.36 per cent, as against an average loss of 33.7 per cent 

 for transplants from spring seeding. The average loss from kale seeded in the 

 field May 8 and thfnned June 20 amounted to 11.2 per cent, as agaltist 21.5 

 per cent from spring-seeded plants transplanted at the .'yime time." 



Notes on some western Buprestidae, H. E. Blkke (Jour. Econ. Ent., 10 

 (1917), No. 3, pp. 325-332). — The author notes the occurrence of. habits, and 

 injury cau.sed by 44 species of the flat-headed borers. A table for the .separa- 

 tion of the various genera of borers and other data are given in a bulletin 

 previously noted (E. S. R., 36, p. 554). 



A new species of Agrilus from California, W. S. Fisher (Canad. Ent., 49 

 (1917), No. 8, pp. 287-289). — Under the name Agrilus burkei the author de-

 of normal, injured, and dying white alder (Alnus rhombifolia) and paper-leaf 

 alder (A. tcnvifoUa) at Placerville. Cal.

 (Oklahoma Sta. Bvl. 113 (1917), pp. S-8, figs. 4).— A brief sunnnary of infor- 

 mation on this beetle, which is one of the most injurious pests of the locust 

 tree in Oklahoma, where many of these trees are grown for posts as well as 

 for shade. A bibliography of 24 titles is included. 



Studies of this pest by Carman in Kentucky have previously been noted 

 (E. S. R., 35, p. 552). 



A new species of Xylotrechus, W. S. Fisheu (Proc. Ent. Soc. Wash., 18 

 (1916), No. 4. pp. 214-216). — Xylotrechus aceris, a new cerambycid which

 in Pennsylvania. Delaware, and Kentucky. 



The horse-radish flea-beetle: Its life history and distribution, F. H. Chit- 

 tenden and N. F. Howard (f7. -S. Dcpt. Agr. Bui. 535 (1917), pp. 16. figs. 6).— 

 (Haltica) Phyllotreta armoracice, a European pest thought to have been intro- 

 duced in horse-radish, having first been collected at Chicago in 1893. now 

 occurs from New York and New Jersey to Quebec, Canada, and westward to
