rish and g'ame laws of New Jersey {Trenton, N. J., 1912, pp. 232, pi. 1). — 

 This is a compendium of the New Jersey laws. 



Capture of Raleigh by the wharf rat, C. S. Brimley {Jour. Elisha Mitchell 

 Sci. Sac, 28 (1912), No. 2, pp. 92-9.'i). — The author reports that while known 

 to have been at Beaufort in 1870, the wharf rat was not observed in Raleigh 

 until 1909. Two years later it appeared in great abundance and slaughtered 

 large numbers of young chickens. The wharf rat is strongly inclined to burrow, 

 while the black and brown rats are climbers. 



Life histories of Indian insects, II, D. Nowrojee (Mem. Dept. Ayr. India, 

 Ent. Scr., 2 (1912), Ao. 9, pp. 165-191, pis. 7, figs. 2). — A number of aquatic 

 Hemiptera and Coleoptera are taken up in this second paper (E. S. R., 24, 

 p. 758). 



Recent investigations in insect parasitism, O. H. Swezey (Hawaii. Forester 

 and Agr., 9 (1912), Nos. 3, pp. 83-87; Jf, pp. 130-135). — A review of recent work. 



The effect of heat on certain insect enemies of plants, J. Chaine (Compt. 

 Rend. Acad. Sci. [Paris], 15/, (1912), No. 26, pp. 1833-1836) .—Wish tempera- 

 tures during the latter part of June and early July, 1911, when the thermometer 

 reached 37° C. (98.6° F.) in the shade, together with a prolonged drought, 

 resulted in the destruction of larvaj and chrysalids of the cochylis moth to such 

 an extent that in certain regions the second generation was nearly completely 

 annihilated. The cecidomyid Nonurthropalpus hu.ri, which develops in boxwood 

 leaves, is said to have been similarly destroyed. 



Report of the entomologist, W. V. Tower (Porto Rico Sta. Rpt. 1911, pp. 

 32-36). — The work of the jear consisted largely of the study of the white grub 

 on cane and an ant which infests coffee and practically all its shade trees. A 

 mosquito survey of San Juan was commenced. 



In a study of the flora of practically all districts of the island, undertaken 

 since the bee work previously noted (E. S. R., 26, p. 62), a great number of 

 shade trees used in coffee plantations have been found to produce nectar. In 

 the lowlands guama (Inga laurina), which is by far the best honey plant on 

 the island, is used almost entirely, while in the interior the guava is the princi- 

 pal shade tree in coffee plantations. It is said to be not uncommon for a good 

 strong hive of bees to gather from 5 to 11 lbs. a day from the guama, which 

 blossoms from 2 to 5 times a year, the bloom lasting from 10 to 15 days. The 

 honey produced is very light in color, resembling the clover honey of the North 

 and running about 12 lbs. to the gallon. 



In order to determine the annual production of honey by a good colony, 2 

 colonies were placed on a pair of scales and their weights taken morning and 

 evening. "The readings showed at what seasons the bees were most active; 

 also what flowers produced the greatest quantity of honey. During a period 

 of 9 months from one of the colonies there were extracted 470 lbs. of honey, 

 while the other produced 337 lbs. The only period when both colonies were not 

 gathering was during September, and during this month the small colony gath- 

 ered suflicient honey so that it did not have to use any of its surplus. Begin- 

 ning the latter part of February and through March, April, and May. the bees 

 worked on the general bloom, and it was not uncommon for them to gather
