larva of this dipteran, which occurs as a normal bloodsucking parasite of 

 nesting birds, with fatal results in some cases. The structure of the larva 

 and of the pupa are described, as are the habits and distribution of the adult

A new and interesting genus of North American Tachinidae, W. R.

 tachinid reared at Pasadena. N. J., from undetermined grasshoppers is de-

Kerosene traps as a means of checking up the effectiveness of a poisoned 

 bait spray to control the Mediterranean fruit fly (Ceratitis capitata). with 

 a record of beneficial insects captured in the kerosene, H. H. P. and H. C. 

 Severin (Jour. Econ. Ent., 8 (1915), No. S, pp. 329-338, pi. i).— This paper is

Life history, natural enemies, and the poisoned bait spray as a method of 

 control of the imported onion fly (Phorbia cepetorum) with notes on other 

 cnion pests, H. H. P. and H. C. Sevekin (Jour. Econ. Ent., 8 (1915), No. S, 

 pp. 3Ji2-3oO). — This paper reports upon studies made in Wisconsin of the 

 life history of P. cepetorum, its natural enemies, probable causes of its enor- 

 mous increase, and the poison bait spray for it. In addition briof notes are 

 presented on the blaclc onion fly (Tritoxa flcxa), barred-winged onion fly 

 (Chcetopsis cmea), Euxesta notata, onion thrips, cutworms, miscellaneous in- 

 sects injurious to onions, and insects bred from decayed onions. 



The number of eggs which are laid at one deposition may vary from 1 to 15. 

 Under field conditions the incubation period of eggs deposited by the first brood 

 of P. cepetorum in early June varied from 3 to 4 days. The larval period was 

 completed in from 2 to 3 weeks in green onions, onion sets, and small seeded 

 onions, but in seeded onions from the previous year the develoiimeut of the 

 maggots was often prolonged and, in some instances, required from 4 to 5 

 weeks. The pupal period under field conditions required from 9 to IG days 

 during the latter part of June and early July, the majority of the second brood 

 of flies emerging in 11, 12, and 13 days. They were found to develop in radishes 

 and in manure. The period of emergence of the second brood af onion flies 

 under field conditions extended from June 28 to July 25, most of the flies issuing 

 from July 1 to July 12. 



The rove beetle Aleochara anthonujice is said to be the most important enemy 

 of this pest in Wisconsin. A report of the results of control work with the 

 poison bait spray, by Sanders, has been noted (E. S. R.. 33. p. 357 K 



Concerning a new enemy of the carob bean in Italy, Eumarschalia gen- 

 nadii, G. del Guercio (Rcdia, 9 (1913), No. 2, pp. 227-232, figs. 3; abs. in Rev. 

 Appl. Ent., 3 (1915), Ser. A, No. 1, p. 55). — A dipteran, thought to be Schizomyia 

 gennadii, for which the author erects the subgenus Eumarschalia, is said to 

 have attacked the carob bean in Italy since 1904. In some districts from 50 to 

 60 per cent of the crop is affected. Control consists in the collection of injured 

 beans toward the end of summer, just before harvesting, and placing in an 

 oven or boiling water.
