This lepiuopteran shows a general distribution from New Jersey westward 

 to Illinois and Kansas and southward to Texas. In addition to the lotus 

 (Nelumbo lutca), upon the receptacle of which it feeds, Polygonum, A|iocynura, 

 and Eupatorium serve as food plants. Its natural enemies Include l'anz<ria 

 jH nitiilis and Zo mOl f U Cha (Porizon) facialis, which were reared hy the author. 

 Other species recorded as parasites are lJu.-nri.sla vulgaris, Hypottena rariahili*, 

 PJiorocera oonutocM, and Bracon wantJiostigmua. As a control measure, the 

 author recommends the application of arseulcals in the destruction of the 

 young larvae before they penetrate the Interior of the buds, seed capsules, or 

 stems. 



The Calif ornia pistol case bearer (Coleophora sacramenta), W. M. Davidson 

 {Jour. Econ. Bnt., 11 (1918), No. 6, pp. 446-45B, pi. 1). — Data are presented on 

 the biology of this elachistid, the young larva' of which skeletonize the foliage 

 of plum, prune, cherry, apricot, and apple, particularly cherry and plum, in 

 the San Francisco Bay region of California from June to September. They 

 teed at flrsl as leaf miners and from June to September skeletonize the 

 foliage; from late February to .May the old larvre attack leaf buds, fruit buds, 

 Bowers, foliage, and occasionally the young fruit. There is one generation 

 a year. The adults emerge in May and June, and deposit eggs on the leaves 

 of the food plants which hatch after a period of 26 days. July 1 being the 

 maximum date of hatching. Pupation occurs in April and May, 25 days 

 being required for transformation to adult. 



The larva is commonly parasitized by a small blackish pteromalid (Eury- 

 dinota /la i icorpus) .

 cocoons of Abies ooncolor in Oregon and California, Chrysotoxum euloradensis 

 from Colorado, and Myxosargus nigrkormis from the District of Columbia 

 are described as new.

The dipterous family Cyrtidse in North America. F. R. Cole (Trans. Atner. 

 Ent. Soc. 45 (1919), No. 1, pp. 1-79, pis. 15). — This is a report of studies of the 

 family Cyrtidae, formerly known as Acroeerida?, which extended over a period 

 of two years. Ten species and three varieties are described as new. Notes 

 on their life history and habits are Included. The species of which the early 

 stages are known are parasitic in the egg cases or the bodies of spiders. 



A bibliography of 162 titles is appended. 



Anastrepha fraterculus, a severe menace to the southern United States, 

 E. W. Rust (Jour. Econ. Ent., 11 (1918), No. 6, pp. 457-.',67).— This is a report 

 of studies made during the past two years by the entomologist of the Tucuman 

 Experiment Station, Tucuman, Argentina, in the northern part of which country 

 A. fraterculus is the particular scourge of the fruit grower. Attention is called 

 to the great loss that would result in the southern part of the United States 

 should it once gain entrance. The name South American fruit fly is suggested
