Notes from Connecticut, W. E. Bkitton [Jour. Evon. Eiit., I (1908), So. J. 

 pp. 313-315). — The fall cankerworm (Alsophila pometaria) is said to have 

 caused uuire dainafie in various portions of Connecticut than for several years, 

 shade and woodland trees, includins elm, maple, chestnut, hickory, California 

 privet and oak as well as apple trees being fed upon. The peach sawfly 

 (Pnniih Hills prrsicuni) was greatly reduced in numbers Ity spraying with lead 

 arsi'natc. 



The common red spider, F. II. Ciiittknden ( f. .S'. Drpt. Agr., Jiiir. JJnt. Circ. 

 10.'/. {III. II. fifix. '/). — 'i ct rail lie liHH bimncuhitus. counnonly known as the red 

 spider, is a si)ecies well distributed throughout the eastern United States which 

 attacks a wide range of plants. Several predaceous enemies including Scijmnus 

 punctuni. CcciOoinjfia coccidantin, Chijjsopa nifihtbri.s, and Tlirips .sexmaculata 

 are reported. 



The following remedies are advised: 



" For the greonhouso and for general use, sulphur with neutral, whale-oil, 

 and other soap solutions; kerosene-soap emulsion; and spraying with water. 



" For the treatment of trees and shrubs, the same as the above, with the 

 addition of resin wash and the lime-sulphur and lye-sulphur mixtures. 



" For truck and garden plants, lye-sulphur wash and the same remedies as 

 for the greenhouse, with the addition of clean gardening or farming, early 

 fall plowing. keiM'iug down weeds, and crop rotation where practicable." ' 



The introduction of Iridomyrmex humilis into New Orleans, E. Foster 

 (Jour. Econ. Eiil., 1 ilUOS), Xo. J, pp. 2SiJ-20.j). — The author discusses the 

 probable manner and date of the introduction into this country of the Argentine 

 ant. Since Xew Orleans has had no direct commercial intercoiu'se with Argen- 

 tina and cargoes of coffee have l)een coming from Brazil since the passage of 

 the Comi)romise Act in 1833. it is considered more probable that the pest was 

 introduced from the latter country. 



[Injurious beetles], V. Mayet (Prog. A(/r. et Tit, (Ed. VEst-Centre), 29 

 (1908), No. .')0. pp. 110-716, pi. 1). — Five species of beetles (Cetonia spcciosis- 

 sima, C. sqiiaUdd, C. cinctclUt. LrtJirus ccp/m/o/cs, and Liicaims paraUeJipipcdus) 

 and the nature of their injury to vines are here described. 



Notes on some Cecropia cocoons and parasites, J. B. Smith (Jour. Econ. 

 Ent., I (1908), A'o. J, pp. 293-291). — Ileports having come to the author in the 

 fall and winter of 1007-S of an unusual mortality In Cecropia cocoons, collec- 

 tions were made in New Jersey and on Long Island in order to determine the 

 cause of death. Out of a total number of 1,002 cocoons exaniinetl .3(5 were 

 found to be sound, adults had emerged from 34, 47 had dieil as pupse, 295 

 were parasitized, and 0."0 were dead from disease. Two parasites, Ophion 

 macriiriim and an Ichneumonid form, were found. The hyperparasltes Spilo- 

 cryptus c.rtrcDii.s, HpihxhiiUiH iniirUr. and DibrticJn/s hoiiclicaiiiis were reared 

 in large nuniiters. 



Some insects injurious to truck crops. The semitropical army worm, 

 F. II. CuiTTENDEN aud II. .M. lUssEi.i. (I . S. J)('pt. Ai/r., liiir. Ent. Bill. 66, 

 pt. 5, pp. 53-10, figs. .'/). — Prodenia eridania is reported as the source of con- 

 siderable injury to garden truck in Florida, including tomato, jiotato, sweet 

 potato, eggjdant, pepitcr. okra. coll.-irds. and c(twpeas. It feeds normally on 

 weeds, such as the pokeweed, spiny amaranth, etc., and is confined to semi- 

 tropical America as a iiest. A description presented of its life history includes 

 technical descrii)tions of the egg and C. larval stages by II. (J. Dyar. 



" Experiments show tliat the egg period may be passed in a minimum of 4 

 days, the larval period in 17 days, and that the entire life cycle, in an outdoor 

 summer temperature, would be about 35 days or 5 weeks; also, that there are
