Ent., 46 (IBlJf), Nos. 7, pp. 243-246; 8, pp. 277-284, figs. 3; 9, pp. 309-314).— A 

 review is given of the metliods employed and the results obtained, taken up 

 under the headings of the Mediterranean fruit fly {Ceratitis capitata), melon 

 fly or bitter gourd fruit fly (Dacus cu<:urMt(e), olive fly (D. olece), Mexican 

 fruit fly (Anastrepha ludens), apple maggot, cherry fruit flies (Rhagoletis 

 cingulata and /?. fausta), currant fruit fly, and imported onion fly (Pegomya 

 cepctorum) . The work bj- Italian entomologists has been left for a later paper. 

 References are given to the literature reviewed. 



Report of investigation of the fruit S.y situation in the Territory of Hawaii. 

 F. Maskew (Mo. Bui. Com. Hart. Cat., 3 (1914), ^^o. 6, pp. 227-238) .—" The 

 clean culture campaign has not controlled the Mediterranean fruit fly even in 

 the policed district, nor has it I'educed the amount of infested material recorded 

 as reaching the mainland. The value or not of the clean culture campaign is 

 purely a local problem, and the desirability of a continuance, also provision for 

 its maintenance, is in my opinion a matter for the local authorities to decide. 

 The melon fly (Dacus (■iicurbita') is the source of great financial loss to the 

 producers, and all of its hosts should be included in the list of material covered 

 by the United States quarantine order. 



" The horticultural interests of the mainland would be far better protected 

 by a federal supervision of horticultural exports similar to the system in force 

 in the gipsy nioth area, than by continuing the clean up of house yards in 

 Honolulu and its envii'ons. Every article of commerce between the islands 

 and the mainland, including vessels and persons, constitute a potential danger 

 of introducing the fruit fly at all times, and the commercial shipments of 

 bananas mider the present .system of federal inspe<'tion do not constitute a 

 greater danger of infestation than other articles of general commerce. The 

 question of mail, sealed baggage, and passengers' clothing as avenues of en- 

 trance open at present to various hosts of the Mediterranean fruit fly is one of 

 grave importance, and measures looking to the complete control of the same 

 should be devised in such a manner as will withstand any attempt to defeat 

 their legality, and authority given to the horticultural quarantine officers for 

 their prompt enforcement."

The dusty surface beetle (Opatrum sequale), R. W. Jack (Rhodesia Agr. 

 Jour., 11 (1914), No. 6, pp. 894-901, pis. 2, fig. 1).— This beetle is a source of 

 injury through its habit of devouring maize seed when planted in dry soil. 



In the present paper the author presents the results of field and laboratory 

 studies of the pest which have extended over a period of two years. The experi- 

 ments have shown the poison-bait method to be effective in dealing with this 

 beetle. 



Hymenopterous parasites of Aphis euonymi, A. Malaquin and A. Moitie 

 (Gompt. Rend. Soc. Biol. [Paris], 76 (1914), No. 16, pp. 803-805) .—The authors 

 have found no less than 17 different species of Hymenoptera to parasitize the 

 black beet aphis of which Trioxys auctus and Aphidius crepidis are the most 

 abundant. Preliminary studies of the biology of these two species and their 

 utilization are reported. 



Some notes on parasitism of chrysopids in South Carolina, E. A. McGregor 

 (Canad. Ent., 46 (1914), No. 9, pp. 306-308, fig. i).— Of 99 chrysopid cocoons 

 collected and observed daily 48 yielded parasites and 51 chrysopids. The para- 

 sites reared, in order of relative abundance, are Chrysophagus compressicornis.
