deals with the early history of liquid applications ; the second to 

 spraying in " foreign countries " ; the third to spraying in 

 America ; the fourth to materials and formulas ; the fifth to 

 machinery, &c. ; the sixth to the action of insecticides and 

 fungicides. Part 2 contains specific directions for spraying cul- 

 tivated plants, and there is an appendix dealing with laws 

 regarding spraying and the metric system.

 Connecticut Agr. Exper. Sta. for 1902, pp. 99-178 & i-x, pis. 

 1-15, text-figs. 1-19). The greater part of the report is con- 

 cerned with the San Jose Scale {Aspidiotas perniciosus), pp. 114- 

 38 ; the Apple-tree Tent Caterpillar {Clisiocampa americana), 

 pp. 139-48; and the Whitefly {Aleyrodes vaporariorum?), pp. 

 148-63, the notices of the latter being especially useful.

 pharoceridae) of North America" (Proc. Calif. Acad. Sci. (3) iii. 

 ZooL, pp. 187-232, pis. 18-22). [Diptera.] A valuable contribu- 

 tion to our knowledge of this interesting family, especially in the 

 notices of the immature stages. The author points out that the 

 life-history of no Blepharocerid is fully known, the first eggs of 

 any species being yet to be found ; the food-habits of the male 

 are also unknown.

S. Sawamura, 1902 : Investigations on the digestive enzymes 

 of some Lepidoptera (Bui. Coll. Agric. Tokyo Imp. Univ. Japan, 

 iv, pp. 337-47). Though the expanded part of the intestine in 

 Lepidoptera is commonly called the stomach, its physiological 

 function resembles rather that of the intestines of Vertebrata. 

 There is no part of the intestines in Lepidoptera comparable 

 with the stomach of Vertebrata, since no genuine acid gastric 

 juice exists in them.
