immature stages, observations on its life history, and effect of cold. There 

 were found to be six molts, the average length of time for reaching the adult 

 stage being about 7.5 months. 



In a discussion of the occurrence of the European house cricket (Oryllus 

 domcsticus) (pp. 313-316), M. P. Zappe gives a brief summary of information 

 relating to it and records its occurrence in the attic of a new house at Sheltou 

 where it annoyed the occupants by its nightly chirpings and by getting into the 

 food in the pantry on the floor below. This infestation was controlled by the 

 use of poison baits, one of which contained borax and the other bichlorid of 

 mercury. 



A summarized account of the European corn borer {Pyrausta nuMlalis), 

 which may occur in Connecticut (pp. 316-327), includes an annotated bibli- 

 ography of 21- titles. In a brief account of the bean leaf beetle (pp. 327-329) 

 it is stated that it was reported in 1918 as injuring beans in Connecticut for the 

 first time for many years. 



Injury by the raspberry sawfly {Monophadnoides rubi) (pp. 329-331) in a 

 field of about an acre of red raspberries in New Haven is reported upon in 

 which at the time of examination on May 29 practically all the old leaves had 

 been eaten while the new and tender shoots were uninjured. It is pointed out 

 that since there is only one brood each year, treatment by spraying with hele- 

 bore or lead arsenate is a simple matter if applied in season. The spraying 

 must be done soon after the plants blossom and may be applied even before they 

 blossom to prevent defoliation. 



The Iris I'oot borer {Macronoctua onusta) (pp. 331-333) which was a source 

 of injury to Iris beds through tunneling in the root stalks is briefly considered. 

 A brief account of garden slugs (pp. 333-336) is followed by a report of mos- 

 quito work in 1918 (pp. 337-340) by B. H. Walden. A note on entomological 

 features of the season is followed by miscellaneous insect notes, which deal 

 with a larva on tartariau honeysuckle {Harpiptcrya; sp.), the clavate tortoise 

 beetle (Coptocycla clavata), abundance of potato or cucumber fleabeetle, the 

 rose chafer, salt marsh caterpillar feeding on beans, abundance of 3-liued potato 

 beetle {Lema trilineata), birch leaf skeletonizer (Bucculatrix canadensisella) , 

 leaf tyer on rose (Tortrix albicomana) , Schizura unicornis on hickory, the 

 saddled prominent in Litchfield County (Heterocampa guttiintta), absence of 

 tent caterpillar, an orchid weevil in Connecticut {Diorymellus Iwvimargo) , 

 Chamyris cerintha feeding on privet, white woolly larvae on hickory 

 {Erythraspides carycc), the chrysanthemum gall midge {DiartJiononiyia 

 hypogwa), Culosoma sycoplianta, the stalk borer in corn, the poplar girdler 

 {Saperda concolor), the elm leaf beetle, a tip borer in garden Physostegia 

 {Olethreutes hebesana), and a rare moth (Tetralopha rohustella) attacking 

 white pine. 



[Insect notes] (New Mexico Sta. Rpt. 1918, pp. 24, 25). — In work with the 

 squash bug it was found that blackleaf 40 (1:400), with soap 4 lbs. to 100 

 gal. killed all up to the next to the last stages that are hit. Two applications 

 of this spray at intervals of a week controlled a severe infestation. The 

 chrysoraelid beetle Coptocycla clavata, whose native host plant is Physalis 

 spp., attacked chili plants to a considerable extent in limited areas. Eutettix 

 tenella was the source of considerable destruction through its transmission 

 of curly leaf infection. 



Thirty-third report of the State entomologist on injurious and other in- 

 sects of the State of New York, 1917, E„ P. Felt (N. Y. State Mus. Bui. 202 

 (1911), pp. 2JtO, pis. 12, flgs. 82).— In his report to the director of the State 

 Museum the author includes a discussion of the occurrence of the more im- 

 portant insects of the year and work carried on with them.
