a funnel at the end of a steel tube and connected with a telephone receiver. 

 When the tube is stuclv into the earth the noise made by the crawling termites 

 can be distinctly heard through the receiver even when they are working at a 

 considerable depth in the soil. By means of this apparatus termites may be 

 readily located in the tree trunks of orchards or estates or in the walls of houses 

 and marked for treatment with the arsenic-sulphur fumes," generated in the 

 exterminator apparatus. 



The work closes (pp. 18.5-2.52) with a series of appendixes by various authors 

 who have studied the material collected in Ceylon. The review is by W. M. 

 Wheeler. 



Studies of Mallophaga and Anoplura, E. Mjoberg (Ark. ZooL, 6 {1910), 

 No. 13, pp. 2i)6, pis. 5, figs. 156). — This work on the morphology and classifica- 

 tion of the biting and sucking lice includes descriptions of new genera and 

 species. A host index and bibliography of 14 pages are appended. 



Experiments with cotton stainers, W. Robson (Agr. Neivs [Barbados], 10 

 (1911), No. 235, p. 138). — "Practically no effect on germination was produced 

 by the feeding of the stainers on seed which had been protected during growth, 

 and exposed to the feeding only after being harvested, while the seed which 

 was produced in bolls attacked during growth showed a ve,ry small relative 

 germinating power. . . . The lint was affected to a very serious extent where 

 the stainers were abundant during the development of the cotton." 



The white fly (Aleyrodes citri), F. W. Mally (Texas Dept. Agr. Bui., n. 

 ser., 1910, No. 6, pp. Hi). — A brief summarized account is given, with directions 

 for the preparation and use of insecticides. 



The Aphididae of the vicinity of Hermannstadt, C. Henrich (Verhandl. u. 

 Mitt. Siehenhiirg. Vrr. Natiinr. Ucrniannstadt, 59 (1909), pp. l-lO'f) .—This 

 work on German Aphldida-> includes host and species indexes. 



Danger of general spread of the gipsy and brown-tail moths through im- 

 ported nursery stock, C. L. Marlatt (U. 8. Dept. Agr,, Farmers' Bui. ^55, 

 pp. 22, figs. 7). — This bulletin gives a record of the infested importations of 

 nursery stock during the last 2 years, describes nursery conditions in Europe 

 showing the nature of the infestation there, and concludes with a brief de- 

 scription and illustrations of the 2 moth pests which are now being thus 

 imported. Descriptions and figures are included as an aid to a prompt recog- 

 nition of the pests. 



A new species of Lasioptera with observations on certain homologies, 

 E. P. Felt (Psyche, IS (1911), No. 2, pp. &V/-S6).— The gall midge here con- 

 sidered, L. portiilacw, n. sp., was reared from stem galls on purslane (Portulaca 

 oleraeew) at St. Vincent, West Indies. 



Some facts about malaria, L. O. Howard (U. S. Dept. Agr., Farmers' Bui. 

 J/50, pp. 13, figs. 6). — In this publication, which has been jirepared to meet a 

 strong demand for information on the subject by persons connected with agri- 

 cultural pursuits in various parts of the country, the author considers the 

 nature of the disease, its conveyance by mosquitoes, the mosquitoes concerned, 

 and preventive and curative measures. 



Remedies and preventives against mosquitoes, L. O. Howard (U. 8. Dept. 

 Agr., Farmers' Bui. 4ih PV- 1^)- — This popular account is largely a condensa- 

 tion of the more important of the matter issued in Bulletin 88 of the Bureau of 

 Entomology, previously noted (E. S. R., 24, p. 458). 



Food habits of Megarhinus, F. Knab (Psyclie, 18 (1911), No. 2, pp. 80- 

 82). — The structure of the female proboscis of Megarhinus and personal obser- 

 vations of M. septentrional is and il/. snperhus lead the author to conclude that 

 the mosquitoes of this genus feed wholly upon sweets of flowers. While all the 

 parts of the proboscis found in the females of the blood-sucking species are
