Japanese insect placards, the first showing the Rhynchoton 

 Selenocephalus cincticeps, an enemy of the rice plant, with its 

 parasites, &c. ; the second the Lepidopteron Hemerophila atri- 

 lineata, an enemy of mulberry, also with its parasites. Dr. J. B. 

 Smith discusses " Mosquitocides " (pp. 96-108), and concludes 

 that there are several preparations that will serve both as 

 disinfectants and larvicides, even when highly diluted. We 

 note that the Association numbers eighty-six active, forty asso- 

 ciate, and forty foreign members, a total of one hundred and 

 sixty-six. 



K. Nagano (July 15), 1903: '' Snierinthus planus, Walker 

 {Uchi-suzume)'' ('Insect World,' vii. no. 7, 1 p. Engl, suppl.). 

 [Lepidoptera.] Stated to be the same apparently as S. ocellatus, 

 L. A figure is given, together with one of the larva, which 

 is also briefly described ; its food-plants are noted as Salix, 

 Primus pseudocerasiis, and Pyrus mains. Plate vii. contains 

 twelve figures of waterbugs, named only in Japanese, but re- 

 cognizable; among them are the imago and ova of Notonecta 

 trivittata, Motschulsky. 



H. A. GossARD, 1903 : " Whitefly {Aleyrodes citri) " (Bull. 

 Florida Agric. Exp. Sta. 67, pp. 595-66, pis. i.-vi. ; with a note 

 on its allies by T. D. A. Cockerell, pp. 662-6). [Ehynchota.] 

 This is a valuable contribution to our knowledge of this remark- 

 able family, which links together in some ways the Coccidse and 

 Aphida3, and the type of which was described by LinnEeus as a 

 Tinea. The Citrus whitefly is described and figured in all stages 

 and in great detail ; it is of unknown origin, though probably 

 American, and is the worst orange pest where it now occurs. 

 In Florida there are three annual broods, and there are few in- 

 sect enemies, though two fungous diseases are more or less 

 efficient in suppressing it.

 and figures are given, amongst others, of various Longieorn 

 Coleoptera injurious to coifee, cocoa, and india-rubber.

E. E. Green, 1903 : " The Lobster Caterpillar," a tea pest in 

 Ceylon {op. cit., ii. pp. 95-107, 3 pi.). Capua coffearia was de- 

 scribed as far back as 1861, but has only come into prominence 

 as a tea pest of late years. Mr. Green has worked out the com- 

 plete life-history. The Lobster Caterpillar [Stauropus altenius, 

 Walker) was formerly considered as somewhat of a prize by the 

 collector of Lepidoptera, but has recently appeared in enormous 

 numbers on certain tea estates in Cej^lon. It occurs also in
