Insect enemies noted were rudtsufi macuUventris and the usual tachinid; the 

 eggs of the latter being seen on 3 to 4 per cent of the larvae. Harpaline ground 

 beetles were abundant and Lehia grnndis is thought to have been a factor in the 

 control of the potato beetle. 



A number of experiments performed with a view to discovering the cheapest 

 and most effective insecticide for coutrolliug the pest are reported. " In con- 

 clusion it is suggested that at least 3 thorough applications of Paris green, or 

 arsenate of lead, with Bordeaux mixture be made, the first applied about the 

 time that the first eggs begin to hatch, and the later applications at intervals 

 of about 3 weeks. By this method the beetles should be easily controlled and 

 the injury therefrom almost entirely obviated." 



The blue-green beetle, J. 8. Houser {Ann. Rpt. Cuban Nat. Hort. Soc, 3 

 (1909), PI). o.i-oS). — While there are 3 species of the Cuban blue-gi'een beetle, 

 Pachnwus azurescens is responsible for most of the injury to Cuban citrus 

 products. The biology of this pest is briefly considei-ed. Field experiments are 

 said to have demonstrated that spraying with poisons can not be relied upon to 

 fully control the beetle ; that the ordinary spray mixtures of poisons adhere 

 with difficulty to the oily, growing shoots of the citrus plants, and that knapsack 

 sprayers are wholly inadequate for nursery orchard spraying. The collection of 

 adults, the encouragement of birds, the possible spraying with poisons, and the 

 promoting of the general health of the trees are the measures recommended. 



Notes on some of the Eucnemidae of the Eastern States, R. W. Van Horn 

 (Proc. Ent. Soc. Wash., 11 {1909), No. 2, pp. 5^-62, pi. 1, figs. 2).— An account 

 of the habits of these beetles. 



Some species of Calligrapha, F. Knab (Proc. Ent. Soc. Wash., 11 {1909), No. 

 2, pp. 83-87). — Calligrapha rhoda, which feeds exclusively upon the hazel 

 {Corylus americana) , both in the imago and larval stages; C. roivena, the food 

 plant for which is unknown ; and C. amelia, which, in the imago and larval 

 stages, recurs exclusively upon alder {Alniis rugosa), are here described as 

 new. C. phUidcliihica is said to live only upon Cornus (C. stolonifera) . 



The sweet potato weevil {Agr. Neics [Barbados], 8 {1909), No. 192, p. 282, 

 figs. -i). — A brief account is given of Cri/iitorhynchus batatw which attacks 

 sweet potatoes in the field. 



A brief note on Chalcodermus collarishorn, J. A. Hyslop {Proc. Ent. Soc. 

 Wash., 11 {1909), No. 1, p. -JO). — This weevil was bred from seed pods of 

 Cassia chamcechrista at Marr's Station, Md. 



New Chalcidoidea, J. C. Crawford {Proc. Ent. Soc. Wash., 11 {1909), No. 1, 

 pp. 51, 52). — Lciicospis robcrtsoni from Florida and Lariophagus texanus, para- 

 sitic on Laria (Brnchus) prosopis, also bred from stems of Lcucosyris spinosus 

 at Victoria, Tex., are described as new to science, the latter species represent- 

 ing a new genus. 



A new family of parasitic Hymenoptera, J. C. Crawford {Proc. Ent. Soc. 

 Wash., 11 {1909), No. 2, pp. 63, 6J/, pi. 1). — Vanhornia eucnemidarum secured 

 from the cells of larvae of the family Eucnemidae represents a new family 

 (VanhorniidiB), genus, and species. 



Report of the state entomologist [of Nebraska for 1907-8], L. Bruneb 

 {Rpts. State Ent. and Bot. Nchr. 1907-8, pp. 5-13, figs. 2).— Brief mention is 

 made of the insects investigated from July to December, 1907, previously noted 

 from another source (E. S. R., 20. p. 114(3; 21, p. 249). 



Among the more injurious insects investigated in 190S were the box-elder 

 aphis, melon aphis, strawberry leaf-roller, corn earworm, chinch bug, and sev- 

 eral species of social caterpillars including the walnut datana, fall webworm, 

 and white-marked tussock moth. In the uurseries of portions of the State,
