have been n-commended for coiiibating tlu- insoct. in tlie larval, pupal, and adult 

 stages. The n?e of arseuites a<j;ain«t the larva' in Italy is said to be attended with 

 more danger than in the United States. The author recommends, therefore, toljaeco

The grain lantern fly (Tettigometra obliqua), G. dkl Guercio {Niwre Relaz. 

 R. Staz. Ent. Ayr., 1. ser., 1900, No. .1, pp. 13')-14~^, Jhjs. .;!).— The author describes 

 this insect in all its stages and gives tables showing variation in size of various parts 

 of the body. The damage caused by the species is probably greater than usually 

 Supposed, since some of its injury is attributed to other insects. Injuries are espe- 

 cially marked on the tender portions of the food plants. After the grain becomes 

 larger and the epidermis more firm, the injury is less pronounced. In preventing 

 damage from this insect the author recommends planting early varieties of grain and 

 early in the season, in order that the grain may be well developed before the insects 

 begin their attack. The use of fertilizers is also recommended for the same purpose. 

 Stubble should ])e burned over in order to destroy the insects which have collected 

 on green radicle leaves and on grasses which may grow in the grain fields. 



The grain lantern fly fastens itself to the stems of grain by means of its beak and 

 does not move until ready for its final transformations. After the grain harvest the 

 species migrates to grasses of various sorts. 



Some insects injurious to stored grain and the cereal products, B. F. Mac- 

 Cartney {Penii>!i/lratiia Dept. Agr. Rjit. WOO, pf. 1, pp. SS-90, fgy. S). — Brief descrip- 

 tive economics and biological notes are given on Angoumois grain moth, granary 

 weevil, saw-toothed grain beetle, l)ean weevil, pea weevil, Mediterranean flour moth, 

 Indian-meal moth, and confused flour beetle.

 and means of combating Ephesfia kuhnielln, and common species of grain beetle. 



Scale lice on the sugar cane in Java, L. Zehntner {Meded. Froefstat. Suikerriet 

 West Java, 1901, No. 52, pp. 18, pis. 2) . — The author describes in detail an undeter- 

 mined species of Aspidiotus and one of Planchonia. Notes are given on the life 

 history and habits of these insects. The first species was found parasitized by a 

 member of the family p]ncyrtin;e, while a parasite of the family Aphelinpe was bred 

 from the second species. 



The life history of two species of plant lice inhabiting' both the w^itch- 

 hazel and birch, T. Per(;ande ( U. S. Dept. Agr., Divi.noii of Entoniology Bid. 9, tech. 

 ser., pp. 44, fgi^- 2S). — The stem mothers of Horniaphis hamamelidis are hatched from 

 winter eggs in early spring and make their appearance about a week before the leaves 

 of the witch-hazel unfold. This generation causes the development of conical galls 

 on the leaves. In each of these galls from 100 to 120 larvae are produced by the 

 stem mother. These larva^ reach maturity within from 16 to 20 days and are all 

 possessed of wings constituting the migratory generation. The migratory period 

 extends from May until July. There is only one generation of migrants in each gall. 

 The migrating forms fly to birch trees, where they dei)osit larva' on the underside of 

 the leaves. The third, fourth, and fifth generations on the leaves of the birch are 

 very similar in appearance and life history. The fifth generation becomes mature 

 about the middle of August and produces larvae which resemble Aleurodes in form. 

 The sixth generation, after passing through 4 molts, acquires wings and migrates 

 back to the witch-hazel. From these fall migrants another generation of males and 

 females is developed and the eggs are dei)Osited, in which form the species passes 

 the «\'inter. 



The life history of Ilamainelistes spinosrix resembles that of the species just men- 

 tioned except for the fact that the galls on witch-hazel are developed in the flower 

 buda rather than on the leaves, and the species hibernates on birch, requiring, there- 

 fore, more than a year for a complete life c;ycle. The winter eggs are deposited from
