ENTOMOLOGY. fi5 



Brief notes were given on the lial)itH and life liistory of forest tent caterpillar, pea 

 weevil, tussock moth, clover-root borer, and cahhage-root maggot. J. A. ^loffat 

 (pp. 42-52) presented notes on the liabits and means of combating carpet beetles, 

 and gave a detailed account of the life history of Archippus butterfly. The eggs of 

 (hrysopa were found parasitized to a certain extent by an Inchneumon fly. T. W. 

 Fyles presented an account f)f the dragon flies of Quebec (pp. 52-57). The possi- 

 bility of silkworm industry in Ontario was discussed by W. Lochhead (pp. 57-59). 

 !t was concluded that the cost of labor and price of silk precluded the practicability 

 of the establishment of the silkworm industry in Ontario. F. M. Webster (pp. 

 '|-()1) reported the result.s of experiments with petroleum by X. A. lladden on 

 I atawba Island. Peach trees were killed by sj)raying with undiluted crude petro- 

 k'um on ]\Iarch 10, 1900, while 1 jieach tree and some plum trees escapeil injurj' 

 after ])eing sprayed on the same day. J. Fletcher (pp. 62-72) gave notes on the 

 habits and life history of Hessian fly, cutworms in grain, white grubs, pea weevil, 

 pea moth (Seniami nigrieana) , destructive pea aphis, clover-root borer, clover weevil 

 {J'In/ionomus punckilus) , imported cabbage butterfly, cabbage-root maggots, asparagus 

 beetle, cabbage aphis, codling moth, plum curculio, palmer worm, etc. W. Loch- 

 head (pp. 72-78) presented notes on fruit-bark l)eetle, San Jose scale, bean fly, 

 {Anthomyhi rmUciiin] , asparagus l)eetle, Hessian fly, pea weevil, bollworm, and 

 imported cabV)age butterfly and squash bug. F. M. Wel)ster (pp. 81-84) reported 

 observations on Sapt'rdu veKtita, which was found injuring linden trees in nursery 

 rows, and Ohfrea bhiuwulata as a pest of small fruits. 



The luibits of Dennestes talpinus and other species of this family were discussed. A 

 brief account of the present status of the San Jose scale in Ontario was given, together 

 with notes on Ti/nx/lyphus mains as a parasite of San Jose scale. 



Miscellaneous notes on injurious insects, \'. H. Lowe {Nev York Slate Sta. Bui. 

 ISO, jtp. Ihi-lSn, ],h. S,rii/s. ,.^).— The forest tent caterpillar (pp. 115-122) is reported 

 as having been unusually destructive to orchard trees. Circular letters were sent to 

 correspondents throughout the State for the purpose of obtaining information con- 

 cerning the abundance and injuriousness of this species. The localities of its occur- 

 rence are given and the life history of the insect is briefly described. As remedies 

 for this insect the autlior recommends the destruction of egg masses, which is mo.st 

 conveniently done at the time when the trees are pruned, banding the trees to pre- 

 vent the caterpillars from crawling back after being jarred off, and spraying with 

 arsenical poisons, such as Paris green, arsenite of lime, or arsenate of lead. Kero- 

 sene oil ajiplieil directly to the cater]>illars on the trunks and branches of trees gave 

 .«ati.sfactory results. ('ater])illars may also l)e dislodged by streams of water from 

 hydrants. The cocoons are conspicuous and may be readily gathered l)y children. 



The frult-l)ark })eetle (j)j). 122-128) is reported as attacking the branches of cherry, 

 l»each, anil other fruit trees. During late summer and fall the beetles make short 

 galleries in the thick bark of the trunk and large limbs and longer galleries in the 

 .sapwood of twigs and small limbs, in which the eggs are laid. In a peach orchard it 

 was noticed that the most extensiw injury was done to Crawford and Reeves Favoi'- 

 ite varieties. Injury to twigs is shown by the death of the leaves and by drops of 

 sap which exuile from the burrows. The number of eggs in each Inirrow vary from 

 I to 12. The numlx'r of l>roods ])er year for western New York was not determined. 

 For studying the habits of the beetle under experimentiil conditions, half-inch curtain 

 rings were fastened together and to the bark by means of melted i)arafhn, the beetles 

 being placed in these cells andcovered by a coverglass. Their habits of boring could 

 then be observed. As remedies against this beetle the author recommends a liberal 

 application of a causti(! solution, such as whale-oil soap, 2 lbs. to the gallon of water, 

 about the middle of July. Crude carbolic acid may be added to the solution in 

 the ])roportion of 2 oz. to the gallon. The ctbject of these apjilications is to jirevent
