1072 EXPERIMENT STATION RECORD. 



Humidity of hives during winter (U Apiculteur, 41 (1897), No. 11, pp. 444-454). — 

 A critical summary of the ideas of various authors ou the subject. 



A garden pest, Creoceris lilii Scop, (merdigera F.), C. Schroder (III us. 

 Wchnschr. Enl., 2 (1897), No. S3, pp. 516-518, figs. 4). — The eggs are laid ahout the first 

 of May and hatch about fourteen days later. The larva 1 attack the leaves of Fritillaria 

 imperialis, eating the upper surface and the parenchymatous tissue below it to the 

 epidermis of the under side. The latter and the veins are left untouched. Finally 

 they eat away the leaf at its edge. Since full-grown insects and larva? are fouud at 

 the same time on the food plant it is probable that there are several broods a year. 

 According to Bos the winter is passed in the pupal state, but the author is inclined to 

 think that the fertilized female lives through the winter. When the beetles occur 

 in large numbers they do a very considerable amount of damage. 



Notes on scale insects, II, T. D. A. Cockerell ( California Fruit Grower, 20(1897), 

 No. 23, pp. 4,5). — The following new species appear, along with brief descriptive 

 notes: Aspidiotua andromalas, A. crawii, A greenii, Chionaspis latissimus, Dactylopius 

 edgeworth'uv, Mytilaspis pallida maskelli, and Parlatoria them euonymi. 



Otiorhynchus ligustici, H. Gauckler (IUus. Wchnschr. Ent., 2 (1897), No. 33, pp. 

 524,525). — The proper food plant; of this wingless beetle appears to be alfalfa, 

 though its larva does not dislike the peach and the grape. It often attacks the 

 roots of the latter and does great damage. The beetles eat mostly at night and con- 

 sequently are found in small numbers during the day. 



Our Blissus doriae, K. Sajo (lllus. Wchnschr. Ent., 2 (1897), No. 29, pp. 449-451).— 

 This species is compared with its American relative; B. leucoptcrus. It does not go 

 into cultivated fields and is not so easily affected by Sporotrichum gloouliferum. 



A concealed enemy of the raspberry, G. Muller (lllus. Wchnschr. Ent., 2 

 (1897), No. 30, pp. 469-471, figs. 8). — A portion of the life history and the habits of 

 Bembecia hylceforniis are described. The insect sometimes attacks the cultivated 

 raspberry. The larva is found in the interior of the young shoots, seldom in those 

 of theprevious year's growth — almost always with the head directed upward. The 

 author states that the moth is not exclusively nocturnal, and that there are two 

 broods a year. A number of braconid and ichneumon parasites of the insect are 

 known. Meniscus pi mplator and Bracon rcgularis are mentioned. 



Insect enemies of potatoes, I. V. Roberts and L. A. Clinton (New York Cornell 

 Sta. Bui. 140, pp. 391. 39.'). — Brief notes are given on the leaf flea beetle and Colo- 

 rado potato beetle, with suggestions for their destruction. 



The use of arsenites on tobacco, II. Garmax (Kentucky Sta. Bpt. 1896, pp. 69-80, 

 pis. 2).— Areprint from Bulletin 63 of the station (E. S. R., 8, p. 319). 



Triconympha and other parasites of Termes flavipes, .J. P. Porter {Bui. Mas. 

 Comp. Zool., 31 (1897), No. 3, pp. 47-67, pis. 6). — This deals with Trichonympha agilis, 

 Pyrsonympha vertens, Dinenympha gracilis, and Gregarinida — protozoan parasites. 



The large libellulids considered as useful animals destroying noxious insects, 

 R. Martin (Excerpt from Bui. Soc. Nat. Accllm. France, 1897, pp. 4). 



Report of the entomologist, II. Garman (Kentucky Sta. Bpt. 1896, pp. XXIV- 

 XXVIII, figs. 3). — The author notes that complaint of insect depredations in Ken- 

 tucky were more than usually frequent during 1890. Requests were received for the 

 parasite fungus for the destruction of chinch bugs from thirteen different counties. 

 The objection to the use of the fungus that the bugs are slowly affected by it is noted, 

 but it is thought this defect may be overcome to a certain extent by sending larger 

 packages. The army worm is mentioned as doing considerable injury. 



Analyses of Paris green, W. C. Stubbs (Louisiana Stas. Bui. 49, 2. ser., pp. 198- 

 204). — The text of the State law relating to Paris green is given, the use of Paris 

 green in Louisiana is discussed, and analyses of thirty-nine samples are reported. 

 The samples of Paris green sold on our market show, as a rule, high percentages of 

 arsenious acid (white arsenic), all but one being well above the requirements.
