Life history of the leaf-eating crane fly, Cylindrotoma splendens, A. E. 

 Oamkbok ( i/'». Ent. Soc. Amcr., li (19X8), No. l. pp. 07-89, figs. /:').— The 

 larva? of the species here considered feed «>u the leaves <>f the false bugbane 

 (Trautvetteria grandis) <>n Vancouver Island, B. C. 



Oils tested to trap Trypetidae and Ortalidse, II. II. P. Si;vi:i:in (Mo. /.'»/. Cal. 

 Com. Ilort., 7 (1918), No. 6, pp. 419-423, figs. 2).— Following a brief review of 

 the literature on work with various oils in the trapping <>f fruit flies, the author 

 reports upon studios made at the Maine Experiment Station, particularly with 

 the apple maggot, currant fruit fly, sunflower fly (straussia longipennis) , and 

 an ortalid (Seoptera colon). His experiments show that oils derived from 

 crude petroleum, such as kerosene and paraffin, do not attract the adults of 

 the apple maggot The tests of the effect of various oils on the currant fruit 

 fly have been previously noted from another source (E. S. R., 38, p. 4<;<5). Ex- 

 periments with the hydrocarbons and oil of citronella were performed with 

 sexually mature sunflower flies, but none showed a positive reaction to various 

 quantities <»f these oils. The same was true with S. colon. 



Fruit flies of economic importance in California, II. II. P. SEVERER (Mo. Bill. 

 Cal. Com. Ilort., 7 (1918), No*. 6, pp. 4-30-432, fig. 1; 7, p. 464, fig. 1).— Notes 

 are presented on the apple maggot and siinflower fly (Strau**ia longipennia) , 

 which oviposits in the stalk of the sunflower and in the stalk of the Jerusalem 

 artichoke ( Hcliant litis tuberosum). 



Seasonal and climatic variation in Cerodonta, J. M. Aldrich (Ann. Ent. Soc. 

 Amcr., 11 (1918), An. 1, pp. 63-66). — In this paper the author considers Cero- 

 donta dorsalis, an agromyzid widespread in the United States and Canada, the 

 larva of which mines In the leaves and leaf sheaths of wheat, timothy, etc. 



Observations on the life history and biology of Agromyza laterella, P. W. 

 Claasskn (Ann. Ent. Soc. Amcr., 11 (1018), No. 1, pp. 9-1S, figs. 21).— This La 

 a report of studies of a species which forms galls on the common wild blue flag 

 (Iris versicolor) in the vicinity of Ithaca, N. Y. 



Clytus devastator, a new pest of the Florida orange, E. A. Back (Jour. 

 Econ. Unt.. 11 (l'JIS), No. 5, pp. ^ll-^l'h />'• !)■ — " O. devastator, a cerambycid 

 borer, was first described as a serious pest of Citrus in Cuba in 1S3G, and has 

 since been recorded by collectors, besides in Cuba, at Key West, Chase. Paradise 

 Key, and Palm Beach on the east coast of Florida, and at I'erico Island, close 

 to Anna Maria Key, at the mouth of Tampa Bay on the west coast of Florida. 

 It has been reared from 'Cuban mahogany,' pomegranate (Tunica granatum), 

 and Citrus (orange), and, according to E. A. Schwarzo, has as its preferred 

 host the common mangrove (Rhizophora mangle). Aside from the original 

 statement that it was a serious pest of Citrus in Cuba, it had not been reared 

 from Citrus until it was found damaging orange trees on I'erico Island, Fla., in 

 the spring of 1910. It has demonstrated its capacity to become a serious pest 

 in Florida, and with the extension of the citrus industry still farther south into 

 more tropical portions of the State, or with a rearrangement of its host rela- 

 tionships following further development of the country, it may assume an im- 

 portant role as a pest of Citrus." 



New Zealand timbers and the borer. — A note on the susceptibility of New 

 Zealand timbers to the attacks of the borer, Anobium domesticum, K. 

 Speight (New Zeal. Jour. Sci. and Tcchnol., 1 (1918), No. 3, pp. l',!-1 ', ) ).— The 

 author reports upon an examination of 1.10 New Zealand timbers, and lists the 

 botanical and local names, number immune, and number attacked by A. <!<>mcs- 

 ticum. Soaking the timbers in petrol in which carbolic acid and camphor are 

 dissolved is said to be a thoroughly satisfactory method of treatment on a small 

 scale.
