796 EXPERIMENT STATION RECORD. 



The capture of Lepidoptera by means of acetylene lamps, J. Dewitz (Allg. 

 Zischr. Ent., 9 (1904), No. 19-20, pp. 382-386).— -The author carried out a number 

 of experiments in testing the effectiveness of acetylene lamps of different types in 

 the capture of insects at night, especially Lepidoptera. 



According to the experience of certain authors in the use of these lamps, the 

 female moths which were captured had in the majority of cases already deposited 

 their eggs. The value of acetylene lamps was, therefore, seriously called in ques- 

 tion. In the author's experience, however, nearly all of the female moths captured 

 still contained all of their eggs. This was true in all except 10 of 858 moths exam- 

 ined. Brief notes are given on different species of moths captured. Very few speci- 

 mens of the brown tail moth were found in the lamps. 



The shoot and fruit moth of red and black currants (Bd. Agr. and Fisheries 

 [London], Leaflet 123, pp. 3, figs. 2). — Incurvaria capitella is described with notes on 

 its habits and injurious attacks. Hand picking and burning of infested shoots is 

 recommended, together with spraying by means of kerosene emulsion in fall or 

 winter. 



Notes on Papilio asterias with particular reference to its earlier stages 

 and their difference from those of P. machaon, C. Floersheim (Ent. Rec. and 

 Jour. Variation, 16 (1904), No. 12, pp. 315-317). — Notes are given on the points of 

 resemblance observed between these 2 species of butterflies under different conditions. 



Notes on Prionapteryx nebulifera, F. D.kcke (Ent. News, 16 (1905), No. 1, pp. 

 12-14, pi- 1, fig. 1). — The author describes an apparent case of symbiosis between 

 this moth and black ants belonging to the species Prenolepis parvula. The moth and 

 ants apparently live together in tubes constructed along the stems and in the ground 

 underneath huckleberry bushes. Such bushes were greatly stunted in their growth. 



The fowl tick and hunter ant ( Trinidad Hot. I>ej>t., Bui. Misc. Inform., 1904, No. 

 4-i, pp. 93, 94) . — The injuries from fowl tick are said to be somewdiat less than during 

 previous years and this fact is ascribed to the assistance of the hunter ant. This 

 species is described as a large black ant which prevails in large numbers. While 

 on such hunting expeditions they destroy many forms of insect life. The ants cause 

 considerable nuisance about houses and stables which have to be vacated when the 

 ants appear in large numbers. Horses appear to have a fear of them and attempt to 

 break loose. 



An ant killer (Agr. Bid. Straits and Federated Mala*/ States, 3 (1904), No. 8, pp. 

 306, 307). — For the destruction of ants the use of a mixture containing resin, sal soda, 

 and tobacco tea is recommended. 



Two leaf-miners, F. V. Theobald (Gard. Citron., 3. ser., 36 (1904), No. 929, pp. 

 265, 266, figs. 3). — The lilac leaf-miner (Gracilaria syringella) is described and notes 

 are given on its habits and life history. In combating this pest in gardens and nurs- 

 eries, it is desirable to pick off and burn all infested leaves. The laburnum leaf- 

 miner (Cemiostoma laburnella) is discussed in a similar manner, with notes on its 

 injurious habits. 



In controlling this insect the author recommends the removal and destruction of 

 all rubbish underneath the trees and the treatment of the trunks with a caustic- 

 alkaline wash. 



The larch leaf-miner, F. V. Theobald (Gard. Chron., 3. ser., 36 (1904), No. 924, 

 pp. 181, 182, figs. 2). — Coleophora laricetta is described and an account is presented of 

 its injurious attacks upon the larch tree. The remedial measures recommended 

 against this pest consist in the removal and destruction of infested trees from young 

 plantations or the collection and destruction of the winter cases in small gardens and 

 nurseries. 



The composition of commercial soaps in relation to spraying, L. L. Van 

 Slyke and F. A. Urner (New York Stale Sta, Bid. 257, pp. 427-438).— The investiga- 

 tion reported in this bulletin was undertaken for the purpose of determining the
