Ortel's traps for catching locusts, R. de Saint- Foix (Bui. Agr. Algerie et Tuni- 

 si(\ 8 [1902), No. 14, pp. 34s, 344)- — It was found that by sinking troughs into the 

 soil and partly filling them with water covered with a film of oil the locusts could 

 be induced to jump into the trough, provided a number were caught by other methods 

 and thrown into the film of oil. 



The fundamentals of spraying, A. V. Stkubenkauch {Pennsijlwn'ui Slate Drjd. 

 Agr. Bill. 93, pp. 35, ph. 10, figii. 4)- — Reprinted with slight changes of plirasc(tlogy 

 from Illinois Station Bulletin 68 (E. S. R., 13, p. 876). 



Alphabetical index to North American Orthoptera described in the eight- 

 eenth and nineteenth centuries, S. H. Scudder [Bostoti Soc. Nat. Hist., Occasiomtl 

 Papers, TT, 1901, pp. 436).- — In this paper the author has compiled a list of all known 

 definite references to the Orthoptera of North America and the West Indies, from 

 the time of Linna?us to the close of the last century. The paper includes an alpha- 

 betical index of all the species arranged according to genera, and bibliographical 

 references under each genus, abiV)]iographical list of all literature cited, and an index 

 to the specific names mentioned in the paper. 



The salt-marsh mosquito (Culex sollicitans), J. B. Smith (Science, n. ser., l'> 

 (1902), No. 401, pp. 391-394)- — The experiments and observations of the author on 

 this insect show that the adult deposits its eggs singly in the nuid of salt marshes 

 above ordinary high tide where the sod is not too wet. The eggs may also Ije laid 

 in other situations. They remain in the mud for an indefinite time until unusually 

 high tide or heavy rain covers them with water; they then hatch within a few min- 

 utes and the 'larva? feed on the decomposing mud. The larvte seem to thrive well in 

 botli salt and fresh water. 



Clothes moths (Jour. Bd. Agr. [London], 9 (1902), No. 2,j)p. 221,223).— Biologiail 

 and economic notes are presented on Tinea pellioneUa, T. biseUieUa, and T. tapetzeUn. 

 The attacks of these insects may be prevented in large part by frequent removal and 

 beating of clothes. Exposure to sunlight, the use of benzine, and cold storage at a 

 temperature of 40° F. are recommended. 



Furniture beetles (Jour. Bd. Agr. [London'], 9 (1902) , No. 2, pp. 219-221).— Notes 

 are given on the hal)its and life history of Anobium domesticum and Xestobium tessel- 

 latum. As a remedy for these insects it is recommended that cracks of furniture be 

 painted with a solution of corrosive sublimate, or that infested material be treate<l 

 with benzine or carbolic acid. Fumigation with hydrocyanic acid, where practicable, 

 is exceedingly effective. 



Economy in bee keeping, E. Fokrest (Jour. Jamaica Agr. Soc, 6 (1902), No. 7, 

 pp. 259-^61). — Attention is called to the necessity of keeping the hives and all equip- 

 ment around the apiary in a clean condition in order to avoid diseases among the 

 bees and to secure a better and more marketable grade of honey. 



Apiculture and serotherapy, P. Robinet (Rec. Internat. Apicult., 24 (1902), Nos. 

 6, pp. 133-137; 7, pp. 144-143). — The anatomical details of the stinging apparatus of 

 bees are carefully described and brief recommendations are made concerning means 

 which may be adopted for avoiding bee stings. Natural innnunity to the bad effects 

 of bee stings is acquired in many individuals after being stung from 1 to 30 times. 

 The blood serum ajipears to acquire specific antivenin, which neutralizes the effect 

 of the sting. It is suggested that experiments along this line may perhaps demon- 

 strate the possibility of artifical immunization by means of serum vaccination. 



Foul brood and its prevention in Ireland (Jour. Bd. Agr. [London], 9 (1902), 

 No. 2, pp. 223, 224).— Notes are given on the distribution and prevalence of this 

 disease in Ireland. It is stated that for the purpose of facilitating the adoption of 

 reliable methods for treating this disease hives are being provided with a hole which 

 may be closed with a shutter; a cloth or sjionge saturated with a 10 per cent solution 

 of formalin may be inserted in the hole for fumigation purposes.
