The oviposition of two apple pests, G. W. Hereick {Jour. Econ. Ent., 7 

 {1914), No. 2, pp. 189-192, figs. 3). — This article relates to the green fruit worm 

 and the Palmer worm. 



Observations of the bee moth, F. B. Paddock {Jour. Econ. Ent., 7 (1914), 

 No. 2, pp. 183-188). — This paper is based upon studies previously noted (E. S.

A new destructive cutworm of the genus Porosagrotis, occurring in 

 western Canada, A. Gibson {Jour. Econ. Ent., 7 {1914), No. 2, pp. 201-203). — 

 A cutworm identified as Porosagrotis delorata, probably synonymous with P. 

 orthogonia, has been the source of serious loss to grain crops in southern 

 Alberta since 1911. It is estimated that in the Lethbridge Land District in 1912 

 33 per cent of the grain sown was destroyed. In inspections of the infested 

 districts it was found that beween 30,000 and 35,000 acres of grain were 

 actually being destroyed by cutworms in the southern part of the Province of 

 Alberta. 



It appears to be the habit of this cutworm to travel over the surface of the 

 soil and when a suitable plant for attack is found to burrow immediately and 

 feed just below the surface. In experiments with poisoned bran 25 was the 

 highest percentage killed, the underground feeding habit probably being the 

 cause of the failure to get better results. It is stated that in large fields of 

 sugar beets the attack in 1912 was stopped in 24 hours after the bran was 

 applied. 



Two Microlepidoptera on Thurberia thespesioides, A. BuscK {Proc. Ent. 

 Soc. Wash., 16 {1914), ^o. 1, pp. 30, 31).—Dichomeris deflecta, the larva of 

 which is a leaf folder, and Bucculatrix {IiurhcricUa reared from T. thespesioides, 

 both from Arizona, are described as new to science. 



Feeding habits of Phlebotomus vexator, R. C. Shannon {Proc. Ent. Soc. 

 Wash., 15 {1913), No. 4> PP- 165-161). — This hematophagous dipteran has been 

 found to feed normally upon reptiles rather than upon warm-blooded animals.

 found to bore in hickory logs in the early stages of decay.

 Hermetia illuccns were found to travel 2,500 ft. from a breeding place and 

 become a menace within 32 hours. 



A new tachinid parasite of Diabrotica vittata, W. R. Walton {Proc. Ent. 

 Soc. Wash., 16 {1914), No. 1, pp. 11-14, pl- i)- — A tachinid parasite of the 

 striped cucumber beetle reared at Hyattsville, Md., is described as Neoccla-

The cabbage maggot in relation to the growing of early cabbage, W. J. 

 ScHOENE {New York State Sta. Bui. 382 {1914), PP- 231-241, pis. 6, figs. 5).— A 

 series of preliminary tests which demonstratetl that carbolic acid emulsion and 

 tar pads are the most effective of the various protective and remedial measures 

 commonly recommended for the control of this pest led to the laboratory and 

 field experiments here reported in detail. 



The tests with carbolic acid emulsion at recommended strengths have demon- 

 strated that it will prevent the hatching of the eggs and is fatal to the younger
