which have occurred in priut. He rightly claims for himself the credit 

 of recording for the first time — 



(a) The discovery of the eggs; the numoer of eggs the female de- 

 posits ; that the eggs are inserted from time to time, one in a place, by 

 means of a sharj) ovipositor, through the skin of the apple; that the 

 eggs are deposited in the fruit before it is ripe and in early fruit in early 

 July ; the time required for the eggs to hatch. 



(b) That the larva becomes full grown in from 4 to 6 weess ; that 

 they leave the apple through characteristic openings in the skin, 

 and on grassy ground probably hibernate about the grass roots; that 

 the larvae stored in fruit leave it and assume the pupa state in the bins 

 or barrels ; that they occur in the fruit earlier and during a longer time 

 than before recorded. 



(c) That the flies are on the wing longer than before recorded ; that 

 the later races of flies affect the later fruit. 



The article is illustrated by four plates, upon which are several new and 

 interesting figures. We reproduce his figures of the egg puncture ; of 

 the channels made by the half-grown and full-grown larvae ; of the exit 

 hole of the larvse; of the egg; of the female ovipositor and of the ex- 

 ternal genital apparatus of the male. 



Miscellaneous Notes from the Ohio Station/— In the September, 1890, 

 Bulletin of the Ohio Station, Mr. Weed has four short entomological 

 notes, entitled (xix) Plum Curculio Experiments, (xx) Eemedies for 

 Striped Cucumber Beetle, (xxi) The Rhubarb Curculio, and (xxii), The 

 Clover Stem Borer. In Article xix he details a commercial experiment 

 on a large scale, half of an orchard of nine hundred five-year-old plum 

 trees being sprayed and the other half jarred, the writer concluding 

 that the spraying was as efficient as the jarring while it is much cheaper 

 and easier of application. Moreover, the sprayed trees seemed free 

 from the plum-leaf fungus {Septoria cerasina) and the Brown Rot [Mo- 

 nilia fruciigena). In Article xx an account is given of experiments 

 with certain insecticides and with two gauze net frames, Mr. Weed con- 

 cluding that tobacco powder, liberally applied, is the most promising 

 insecticide, while the simple methods of mechanical exclusion are prac- 

 tical and efficient. In Article xxi the life- history of Lixus concavus is 

 given, and our note on p. 294 of Vol. ii of Insect Life is heeded to the 

 extent of a republication of the references to previous accounts of the 

 food- habits of this weevil. Article xxii adds ten food-plants to the list of 

 those previously recorded for the Clover Stem-borer {Lmiguria mozardi). 

 These are: Melilotus alha^ Urigeron philadelphicus, E. canadensis, Cnicus 

 altissimus, Lactuca canadensis, L. floridana, RudbecMa laciniata, Achillea 

 millefolium^ Campanula americana, and TJrtica gracilis.
