152 THE ENTOMOLOGIST. 



RECENT LITERATURE. 

 Economic Reports: — (1) 0. P. Lounsbury, 1902, "Rep. Govt. Entom. 

 for 1901," Cape of Good Hope, pp. 1-103; 6 plates. (2) Claude 

 Fuller, 1902, " 2ud Rep. Govt. Eutom. (for 1901)," Natal, 

 pp. 1-72; 2 plates and 26 text figs. (3) J. B. Smith, 1902, 

 " Rep. Entom. Dept. New Jersey Agric. Coll. Experiment Sta. 

 for 1901," pp. i-viii, and 463-587 ; 36 figs, (of which 15 are full- 

 page). (4) Cecil Warburton, " Orchard and Bushfruit Pests,

 These Reports are all of the general character of those issued from 

 time to time by their respective Governments. Beyond a brief note 

 relating the introduction of natural checks for insect pests, the greater 

 part of the Cape Entomologists' Report deals with Tick-Heartwater 

 investigations, " Heartwater " being a disease, often fatal, of goats and 

 sheep, supposed to be transmitted by a species of tick [AmbJijonima 

 hebrcBHin). The Natal second Report forms a supplement to the first, 

 with general remarks upon the year's work. We regret to learn that 

 Mr. Fuller's engagement was originally for three years only, and that 

 this may be his last Report. We trust that this may not be the case, 

 but that more enlightened counsel may direct the Natal Government's 

 policy. Mr. Fuller has our sympathy in the apathy of the Natal 

 farmers and fruitgrowers. He made arrangements to deliver three 

 lectures on insect pests, but the first two fell through from "want of 

 time " at tbe meetings ; at the third, which was specially arranged, 

 two individuals turned up, '-the President of the Associatiou and 

 myself." The people of the district certainly deserve the worst that 

 may happen to them. 



Dr. Smith's Reports are so well known that a lengthy notice is un- 

 necessary. The major part of the present bulletin deals at length 

 with the " Mosquito and Malaria " question. An account is also given 

 of the attempts — largely successful — to naturalize the accidentally in- 

 troduced Chinese Mantid — Tenodera sinensis. It is hoped that these 

 predaceous, ever-hungry Orthoptera, which have actually reproduced 

 in New Jersey while at large, will prove valuable allies against some of 

 the worst insect pests of the State. 



The Agricultural Society's Report is of a popular nature, no 

 scientific names being employed, and deals with various orchard pests. 

 It will doubtless be useful to fi'uit-growers. — G. W. K.

 1902),Proc. Acad. Nat. Sci. Philadelphia. Pp. 279-283. Plate xv. 

 Two genera of this rhynchotal family are acknowledged — Aleuro- 

 dicus with thirteen species, all inhabiting the warmer parts of America 

 (except one form from the Viti Isles, which Cockerell suspects was intro- 

 duced upon Fsidiam from America) ; a new subgenus, Dialeurodicus, is 

 formed for the thirteenth species. The second genus, Aleyrodes, is 

 cosmopolitan ; ninety-seven species are enumerated, distributed among 

 five subgenera (three new). It would perhaps have been an improve- 

 ment had full references been given ; the list of species, however, is 

 very useful, and forms a companion to the autlior's well-known Check- 

 list of Coccidae and first supplement thereto. — G. W. K.
