and upon several species of insects attacking cereals, root crops, 

 fodder crops, vegetables, orchard fruits, small fruits, forest trees, and 

 livestock. The following are treated at greater length: Cutworms, 

 red-legged locust {Melanoplusfemur-ruhruni), granary weevils, vegeta- 

 rian carrion ht'etle {Sil2)ha hituherosa), motUed umber moth {Hihernia 

 defoliaria), black vine weevil {Otiorhynchi(.s sulcatusi), and horn fly 

 {Ha'Diatohia serrata). 



Locusts in New South Wales and the Fiji Islands (Sur/or Jour, 

 and Troi). Cult. \(jHecii.sl<nidl is!) I, An;/. 7.;, 2)j>- -^)- — ^" article on the 

 migratory locusts, a propos to the damage which certain species have 

 been doing m New South Wales and the Fiji Islands, particularly in 

 cane plantations. The results of American and European investiga- 

 tions are carefully abstracted, with a special view to practical meas- 

 ures. Kegardnig the Fiji Islands occurrences, it is remarkable tha.t the 

 insects make their appearance most numerously after heavy rains 

 rather than in seasons of drought, as is the case in this countrj^ — l. o.

Experiments with feeding silkworms on mulberry leaves 

 sprayed with Bordeaux mixture, N. Passerini {Staz. S2)er. Agr. 

 ItaL, 20 {1891), No. (I, pp. 503-507). — To determine the deleterious effect 

 300 healthy silkworms in the fourth stage were fed on mulberry leaves 

 from a tree that the day previous to the beginning of the experiment 

 had been sprayed with Bordeaux mixture. After the second day the 

 worms began dying, and the mortality was so severe that but 1 larva 

 passed into the chrysalis state. On analysis, copper in varying (pian- 

 tities was found in the bodies of the dead larv;^ and about i mg. in the 

 chrysalid. In a repetition of the experiment 13 caterpillars became 

 chrysalids. Check larvit' fed as ordinarily suffered few deaths. 



The use of lysol in treating plant parasites, Schiller ( Wiener 

 ill. Gart. Ztf/., 1894, 10, pp. 387-389). — Account of successful use of the 

 lysol in \, ^, and 1 per cent solutions for insects parasitic on various 

 plants. 



Notes on Conchylis ambiguella, and remedies against it, G. del 

 GUEIICIO (*S'^^(;:. ISpcr. Agr. Ital., 25 {I8'.i3), No. 3 and i, pp. 2X0-305). — 

 Notes on the "Tiguuola," and an extended review of experiments in 

 combating it with patent insecticides and emulsions of benzine, alcoholic 

 solution of soap and water, and of kerosene and soapsuds, the last being 

 preferred. 



A kerosene attachment for knapsack pumps, H. E. Weed 

 {Mississippi >Sta. Bill. 30, pp. 35-3s^ji<iH. 2). — Description of an apparatus 

 for mechanically mixing kerosene with water at the moment of apply- 

 ing the insecticide as a sju-ay. The method is recommended as being 

 simpler and more rapid than making a kerosene emulsion with soapsuds 

 or milk, and the results appear to be equally successful.
