Remedies for fleas, A. F. Conkadi {Ncm IfampsJiin' Shi. Hid. 94, pp. S9-92). — 

 A study was made of various remedies wliich may be ajiplied in destroying the dog 

 flea. Persian insect powder and hand picking were found to he too laborious meth- 

 ods or ineffective. The best results were obtained from the use of creolin washes. 

 The animal may be thoroughly washed with the hands or a brush, or may be sub- 

 merged for a period of 5 minutes in a solution of creolin. For dogs a 8 per cent 

 solution is recommended, and for cats a 2 per cent solution. In addition to this 

 treatment it is recommended that rugs be substituted for carpets, and that floors and 

 resting places for dogs and cats be treated with a 5 per cent solution of creolin. 

 Hydrocyanic-acid gas is recommended only as a last resort. 



Mosquitoes in Algiers, Edmond and Etienne Sergent [Ann. Inst. Padeur, 17 

 {190.1 ], X<i. 1, pp. H0-H7, fiijx. 14). — Brief notes on a number of species of niosquitoes 

 collected within a radius of 15 km. of Algiers. In this region 9 species were observed, 

 3 of which are descri])ed as new. The new species are Anopheles aJr/erievj^ls, Culex 

 sergenlii, and ('. utur'ci'. 



Forest mosquitoes and forest malaria, A. Lutz {Centhl. Bakt. u. J*<ir., 1. Aid., 

 S3 {1903), No. 4, Orig., pp. 282-292, figs. 7).— The author discusses the occurrence 

 and frequency of different species of mosquitoes in the forested districts. A number 

 of ])lants have been found which furnish receptacles at the bases of the leaves or in 

 specially modified portions of the leaves in which sufficient water may ])e contained 

 to serve as breeding places for mosi]uito larva\ 



Description of a ne'w Anopheles, C. H. Ludlow {Jour. Ainer. Med. Assoc, 39 

 {190,:^), Xo. cS\ pp. 426, 427). — In the Philippine Islands a number of species of mos- 

 quitoes have been found, including Stegomi/ia fdsciaUi, Culex fatigans, Panoplites afri- 

 canus, and Anopheles philippinensis, the last species being described as new. 



Combating- Anopheles, D. Rivas {Cerdbl. Bakt. u. Par., 1. Ahl.,33 {1902), No. 3, 

 Orig., pp. 23.5-2SS). — Glass vessels were filled nearly full of water and a film of 

 kerosene was gradually spread over the surface. The eggs of Anopheles were then 

 placed upon the surface, and after 2 or 3 days it was found that a number had sunk 

 to the bottom. Some of the larvje, however, developed, 1)ut for the most part rather 

 weakly. In other vessels which were covered with a film of machine oil the larvfe 

 appeared to develop as vigorously as in pure water. The author therefore made use 

 of kerosene exclusively in destroying the eggs, larvj*, and pup;e of mosquitoes in 

 pools and bodies of stagnant water. 



Report of the Agricultural and Mechanical College apiary, F. W. Mally and 

 W. Newell {Austin, Te.r.: Von Boechnann, Schutze ct Co., 1902, pp. 53, pi. 1, tigs. 29). — 

 An appropriation was made by the State of Texas for the purpose of establishing an 

 experimental apiary under the direction of the State entomologist. Notes are given 

 on the establishment of this apiary and on certain experiments which were con- 

 ducted during the first year. It is proposed to study different races of bees and to 

 determine as nearly as possible the comparative length of life of bees of different 

 races. Special attention is given to a study of varicir. drought-resistant bee plants. 

 A large number were found to be partial or total failures. These include a number 

 of native species of leguminous plants, as well as various clovers, English rape, soy 

 bean, velvet bean, etc. Japanese buckwheat gave the best results, while fairly good 

 results were obtained from black mustard, mignonette, and borage. It is stated that 

 in Uvalde County colonies of bees in average seasons yield from 100 to 200 lbs. of 

 honey. A practical manual of bee keeping was compiled and presented as the second 

 part of the report. This contains a discussion of the various matters relating to the 

 care and management of bees.
