580 EXPEKIMENT STATION RECORD. 



An unusual application of propolis by bees in the wild state, X. Tapie 



{Rev. Internal. Apicult., 22 {WOO), Xo. 9, pp. 165-167).— The author made observa- 

 tions on a swarm of bees which was living in a cavity under a large rock. The bees 

 had constructed a wall of prnpolip for protective purposes. 



Report of the entomolog-ist, A. D. Hopkins {]VeM Virginia Sla. Rpt. 1899, pp. 

 25-36). — The chief work of the entomological department of the station for the year 

 was upon forest insects and Hfe zones. The author gives a detailed statement of 

 ^•arious trips made in the State for the purpose of studying these matters. Progress 

 is reported in the study of timothy varieties. Recent reports from correspondents 

 concerning the San Jose scale indicate that this insect has not become a serious pest 

 in any counties of the State west of the mountains.^ 



Insect notes, \V. E. Brixton ( Connecticut State Sta. Rpt. 1899, pt. 3, pp. £40-244). — 

 Xotes are given on the appearance of the pea-plant louse {Nectarophora destructor) 

 in the State. It is reported that Schizoneuru rileyi was injurious to the branches of 

 elm trees during the season. Irregular, warty growths are produced on the branches 

 or tnmks of the trees by this insect. The spruce-bud louse {Adelges abieticolens) was 

 found infesting the twigs of spruces. Notes are given on a number of scale insects, 

 including Lecaniurn armeniueiim, which was found upon grapes and other fruit trees. 

 A l)eetle whi(!h infested wheat middlings and did considerable damage in such situa- 

 tions proved to be Lxmophhu.-i pu»illv.s. Garden primroses and also the native evening 

 primrose were badly injured by the attacks of Haltira marevagans. It is stated that 

 fall cankerworms are much less numerous than during previous years. 



Ho^w insects are studied at the Ohio Agricultural Experiment Station, 

 F. M. Webster {Oldu Sta. Bui. 114, pp. 165-173, ph. 2). — The author presents a popu- 

 lar account of the insectary and breeding cages at the experiment station, and of the 

 methods of collecting, rearing, preserving, and labeling insects. 



Note on Collops bipunctatus, T. D. A. Cockerell {Neiv Mexico Sta. Bui. 33, pp. 

 50, 51). — A brief account of the known distribution of this insect. 



The female of Eciton sumichrasti, with some notes on the habits of Texan 

 ecitons, W. M. Wheeler {Amer. Nat., 34 {1900), No. 403, pp. 56.3-574, Jigs. 4). — 

 Notes on the appearance and biology of species of the foraging ants. 



Synopsis of food habits of the larvee of the Sesiidae, W. Beitenmuller 

 {Oniud. Ent., 32 {1900), No. 10, pp. 301-303). — The author gives brief notes for the 

 purpose of indicating the host plants of these insects and the parts of the host plants 

 which are attacked. 



The Coccidae of Brazil, A. Hempel {Rev. Museu PauUsta, 4 {1900), pp. 365-537, 

 pl.s. 8). — Descriptive, biological, and economic notes on a large number of species of 

 Coccidse, some of which are described as new. 



Effect of lime on the oyster-shell bark louse, W. T. Macoun {Canada E.vpt. 

 Farm.'i Rpts. 1899, p]). 94-96). — Daring the previous year in experiments conducted 

 for another purpose it was noted that whitewash was a very effective remedy for 

 the oyster-shell hark lou.se. Further experiments are now in progress, from which no 

 definite conclusions can be drawn as yet. The insecticide as used in this experiment 

 is composed of 6 gal. skim milk, 30 gal. of water, 60 lbs. of lime, and 10 lbs. of salt. 

 Certain trees which were not treated with whitewash received a spray of tobacco 

 water and whale-oil soap made by using 10 lbs. of tobacco, 2 ll)s. of soap, and 40 gal. 

 of water. The trees were sprayed June 1 and again June 6, with the result that nearly 

 all the insects were destroyed. 



An enemy of the Colorado potato beetle, C. E. Mead {Nea- Mexico Sta. Bui. 33, 

 pp. 47-4^^). — This article has been previously noted (E. S. R., 11, p. 767). 



Preliminary notes on the rate of growth and on the development of 

 instincts of spiders, Annie B. Sargent (Proc. Acad. Nat. Sci. Philadelphia, 1900, No2, 

 pp. 395-411, ph. 2) . — This paper contains a record of observations on Argiope cophinaria
