" From the foregoiug observations it is clear that the presence of rubbish 

 containing organic matter is essential for the development of the flea." 



Buprestids collected in the Philippine Islands, C. Kekremans {Philippine 

 Jour. ScL, Sect. D, 9 (1914), No. 1, pp. 83-90, fig. i).— Twenty-eight species are 

 here listed, of which 12 are described as new to science. 



Notes on Rhabdocnemis obscurus in Australia, A. A. Gieault (Canad. Ent., 

 46 {1914), No. 5, pp. i7-^-i79). — The author presents notes on the biology of 

 this borer, which has been the source of injury to sugar cane in north Queens- 

 land. 



The Tenebrionidae of the Philippines, H. Gebien {Philippine Jour. 8ci., 

 Sect. D, 8 {1913), Nos. 5, pp. 373-400; 6, pp. 401-433) .—This paper records 88 

 forms, of which 4 genera and 41 species are described as new to science. 



The cowpea weevil (Pachymerus chinensis), J. A. Krall {Oklahoma Sta. 

 Circ. 31 {1914), PP- 8). — In an introduction to this circular C. E. Sanborn 

 summarizes the measures which have been the most satisfactory in controlling 

 the cowpea weevil, which has caused an almost total destruction in the bin of 

 seed peas in Oklahoma. Notes on controlling the cowpea weevil follow. 



In cold storage experiments cowpeas kept at temperatures as low as from 26 

 to 31° F. for periods ranging from 58 to 184 days gave a germination of 86 to 

 95 per cent and varied but little from the checks kept. The observations show 

 that when any of the stages in the life cycle of this weevil are subjected to a 

 temperature of 32° or below they will not mature. Notes on hot water, dry 

 heat, carbon bisulphid, and kerosene treatments follow. The remedies recom- 

 mended include immersion of the seeds in water at a temperature of 130° for 

 1 minute and after 2 minutes' interval a submersion for another minute ; heat- 

 ing of the seed in a steady temperature of 130° for a period of 2 to 4 hours ; use 

 of 1 lb. of carbon bisulphid to 40 bu. of seed in an air tight bin ; and spraying 

 peas, thinly and evenly spread on a canvas or floor, with kerosene at the rate of 

 1 pint to 10 bu. or 600 lbs. of peas. In the kerosene treatment an atomizer, 

 hand spray pump, or very fine sprinkler should be used, after which the peas 

 should be shoveled so as to bring the treated and untreated seed together until 

 all have an equal coating of the kerosene. 



The temperature of the bee colony, B. N. Gates ( TJ. 8. Dept. Agr. Bui. 96 

 (1914), PP- 29, figs. 8). — This paper is based upon work conducted during the 

 period extending from October 22, 1907, to September 26, 1908, during which 

 time over 2,576 observations and 20,000 separate readings were made. It de- 

 scribes the apparatus made use of, the arrangement of the thermometers, 

 methods of observation and recording, the consumption of stores in winter, 

 general phenomena of the cluster in winter, the temperature below frames in 

 relation to the outside air, comparisons of temi)eratures of the center of the 

 cluster and of the outside air, effects of manipulation on the cluster, behavior 

 of the cluster in winter, temperature accompanying the laying of the first eggs, 

 transition from winter to summer conditions, general phenomena of the sum- 

 mer temperature, the effect of " orientation " or " play flights," effects of clus- 

 ter heat on the temperature below the frames, the effects of storm, and the 

 effects of transportation on the temperature of the colony. 



A paper relating to the subject from the same Bureau has been recently 

 noted (E. S. R.. 31, p. 254). 



Bee diseases and bee enemies, R. S. MacDougall {Trans. Highland and 

 Agr. Soc. Scot., 5. ser., 2S {1914), pp. 150-169, figs. 2).— This general account of 

 the subject summarizes the main results of recent work. 



Foul brood, F. E. Millen {Michigan Sta. Spec. Bui. 64 {1914), pp. S).— This 

 bulletin, which is supplementary to one recently noted (E. S. R., 28, p. 456),
