856 EXPERIMENT STATION EECOED. 



By n postal card canvass it was deterinined that Brood II of the periodical 

 cicada, or 17-.year locusts, appeared in 1911 in the same localities as in previous 

 cicada years, being present in Hartford, New Haven, and INIiddlesex counties. 



The maple-leaf stem-borer {PHopliorus accTic(iuli,s) was again found in 1911. 

 "Apparently it was more abundant in 1911 than it has been since 1906. . . . 

 The petioles or stems of the leaves are tunneled by the larvre, and break off at 

 a point half to quarter of an inch from the blades. The blades fall late in 

 May and early in June, often covering the ground, while the stems or petioles 

 remain upon the tree until 10 days or 2 weeks lator, when they are shed and 

 drop to the ground." 



A brief account of preliminary tests to prevent damage by the white pine 

 weevil {Pissodes strobi) is presented by W. E. Brittou and B. H. Walden (pp. 

 307-309). This is the most serious insect pest of young white pines in Con- 

 necticut; while it has been present in the State for a great many years, its 

 injury has greatly increased during the past few years owing to the fact that 

 white pine is being extensively planted as a forest tree. Although the experi- 

 ments conducted were not extensive enough to form any definite conclusions, 

 they indicate that considerable injury from the weevil can be prevented by 

 spraying leaders with lead arsenate at the proper time. 



A brief account is given of the cherry tent-maker or cherry tortrix (Archips 

 cerasivorana) which, as it attacks chiefly the choke cherry, can scarcely be 

 considered an injurious insect. This is thought to account for the small num- 

 ber of references to it. 



The poplar mocha-stone moth or tent-maker, MeJaloplia {IcMhyura) inclusa, 

 continued to be abundant in 1911. The caterpillars feed gregariously upon the 

 different kfbds of poplars and willows, and make small webs which remain on 

 the twigs and resemble the winter nests of the brown-tail moth. 



Accounts of The Colorado Potato Beetle (pp. 311-313) and of The Peach Saw- 

 fly (PampJiilius persicum) in Connecticut in 1911 (pp. 314, 315), are given by 

 B. H. Walden. An account of The Leopard Moth, here presented (pp. 317-638), 

 has been previously noted as Bulletin 1G9 (E. S. R, 26, p. 556). 



Brief notes are also given on the migration of the cotton moth (Alabama 

 argillacea) into Connecticut, of a tachinid parasite (LatreilUtnyia hifasciata) 

 of the imperial moth (Basilona imperialis), a borer (Dioryctria abicteUa) in 

 spruce twigs, the prevalence of the hickory bark borer (Scolytus quadrispino- 

 sns), the apple-leaf crumpler (Mineola indiginella) , the chrysanthemum leaf- 

 miner (PJiytomyza chrysanthcmi) , the occurrence of tent caterpillars, woolly 

 pine aphids (Chermcs pinicorticis and C. pinifoliw), the woolly apple ajihis, 

 the elm scale, the woolly maple leaf scale (Phenacoccus acericola), the locust 

 borer (CyJlcne robimw), and on ortho-arsenite of zinc. 



Report of entomologist, R. I. Smith (North CaroUna Sta. Rpt. 1911, pp. 

 3^-37). — This is a brief report of the work of the year with notes on the occur- 

 rence of insect pests, including the spring grain aphis (Toxoptera gramimim), 

 which was unusually numerous and injurious to oats and wheat at West 

 Raleigh; corn flea beetles (Chwtocnema parcepunctata and C. pulicaria), which 

 were very abundant and destructive to young corn during May and June ; and 

 red spiders (Tetranychus gJoveri), which appeared in remarkable numbers in 

 gardens in the vicinity of the station, many reports of their presence on cotton 

 also being received. 



Entomolog'ical investigations (Philippine Agr. Rev. [English Ed.], 5 (1912), 

 No. 1, pp. 37-.'i0). — This report covers the year ended June 30, 1911. 



It is stated that considerable damage is caused in tobacco factories of Manila 

 by a cigarette beetle, in the field by the tobacco aphis, stem borer, cutworms, 

 budworms, etc., and in warehouses by the tobacco moth. In some of the mango
