ENTOMOLOGY. 3()7 



The following birds were observed canying liaiiT caterpillars to their 

 .young: Black-and-white warbler, blue jay, scarlet tanager, wood 

 thrush, chickadee, yellow-throated vireo, red-eyed vireo, crow, cat- 

 bird, black-billed cuckoo, yellow-billed cuckoo, yellow warbler, and 

 chestnut-sided warbler. A pair of red-eyed vireos made 125 visits in 

 10 hours and a pair of rose-breasted grosbeaks made 426 visits in 11 

 hours to secure caterpillars for their young. The birds which are 

 most concerned in the destruction of hairy caterpillars belong to the 

 following families: Cuckoos, woodpeckers, flycatchers, crows, orioles, 

 sparrows, tanagers, vireos, warblers, mocking thrushes, wrens, titmice, 

 and thrushes. The author gives a list of 47 birds which feed on these 

 caterpillars. Many birds prefer smooth caterpillars when they can be 

 had, A new colony of gypsy moths discovered in Georgetown, Mass., 

 was seen to be visited by largc^ numbers of several species of birds, 

 and it is believed that the injuries from the gypsy moth were consid- 

 erably reduced by the help of these birds. 



Bee wintering, A. Gale {Agr. Gaz. Ncir Sottth Wales, 11 (1900), No. 8, pp. 

 6S5-6S8, pi. 1) . — The author states that in the Australian Colonies bees are exposed 

 to greater dangers in the warm months than in the cold months. It is recommended, 

 therefore, that beehives and houses Vje constructed especially for the purpose of 

 properly protecting bees during the hot season. The same mechanical devices which 

 prevent the absuri)tion of heat also prevent the radiation of heat. 



The pollination of fruit by honey-bees, W. R. Lazenbv {Pror. Soc. Prom. Agr. 

 Sci. 1899, pp. 68-7o). — This is essentially the same as an article previously published 

 by the author (E. S. R., 11, p. 956). 



Protective powers of insects against cold, H. Roedel (Helios, 17 (1900), pp. 

 69-78). — A discussion of recent literature on this subject, especially that of the 

 extensive investigations of Bachmetjew. 



Entomological notes on specimens received during 1899, W. W. Froggatt 

 (Agr. Gaz. New Soutli Wales, 11 (1900), No. 8, pp. 639-05 1, pis. '2). — In this article 

 the author gives economic and biological notes on the following insects: Ambrosia 

 beetle (Nyleborus .solidus); Tenebrio molitor; Etltemaia sellata, injurious to garden 

 crops in the caterpillar stage; Prosayleus comosus, attacking the foliage of fruit trees; 

 Desiantha caudata, also injurious to fruit trees; Paramorpha aquiUna, injurious to 

 oranges; Nola metallopa, feeding upon the foliage of eucalyptus; Nerius lineolatus, 

 injurious to the banana; CJattleya fly ( Cecidomyia sp.) ; and Pochazia australis. 



Notes on insects of the year 1899, F. L. Harvey (Maine tSta. Bui. 61, pp. 31-42., 

 figs. 2). — This bulletin contains brief notes on the chinch bug, elm plant louse, forest 

 tent caterpillar, Buffalo carpet beetle, etc. The brown-tail moth (Euproctis chrysor- 

 rhcea) is reported as occurring in South Berwick and Kittery Point. At the latter 

 locality the insect is supposed to have been introduced two years before on house- 

 hold goods shi}jped from Cambridge, Mass. 



Insects of New Jersey, .1. B. Smith (New Jersey State Bd. Agr. Rpt. 1899, pp. 755, 

 figs. 328). — A popular account is given of the life history, habits, and classification of 

 insects in general, the injury caused by insects, and methods of preventing such 

 damage. The greater part of the article is occupied with a catalogue of the insects 

 found to occur in New Jersey with a brief characterization of the different orders 

 and families, and notes on the more important injurious species. 



New insect pests of the year 1899, W. Lochhead (Ontario Agr. Col. and Expt. 

 Farm Rpt. 1899, pp. 34-37, figs. 4)- — Brief notes on the asparagus beetles (Crioceris 

 asparagi and C. 12-punctata) , Plutella crueiferarum , the pea louse, and the corn aphis.
