Kirby ; B. lanta, Lee. ; Melanophiki conspula, Lee. and M. longipes. 

 Say [acumiruiki, De G.), these two species causing much annoyance 

 to lumber men by their bite ; M. drummondi ; M. gentilis, Lee. ; 

 Chrysohothris caurina, Horn. ; C. laricis, Van Dyke ; and Chrysophana 

 placida, Lee. 



Buprestis laevivenfris, Lee., seems to prefer old dry logs and poles 

 without bark, being the only species which has been noted as depositing 

 its eggs in or on such logs. 



Chrysohothris nixa, Horn, and C. viridicijanea, Horn, are recorded 

 as breeding only in incense cedar {Libocedrus decxrrens) and C. syl- 

 vania, Fall., and C. mali, Horn, on fruit trees. 



Agrilus politus. Say, was found on willows, in which it breeds, and 

 oak. A blue form, which may be a distinct species, seems to be 

 confined to the alder. 



WoLcoTT (G. N.). Influence of Rainfall on Abundance of Moth. (Lep.) 

 — Entom. News, Philadelphia, xxviii, no. 4, April 1917, p. 161. 



From observations made over a period of several years in Louisiana, 

 Cuba, Jamaica, Trinidad and Barbados and for two years in Porto 

 Kico, it has been found that the abundance of the sugar-cane moth 

 stalk-borer [Diatraea saccharalis) varies inversely with the rainfall 

 [see this Review, Ser. A, iv, p. 115].

 The author confirms the fact [see this Review, Ser. A, v, p. 238] that 

 a small black ant preys upon the black fly of citrus [Aleurocanthus 

 tvoglumi]. 



Citrus Black Fly around the Home.— J/. Jamaica Agric. Sac, Kingston, 

 xxi, no. 3, March 1917. pp. 88-89. 



Citrus trees infested with Aleurocanthus wogluini should be sprayed 

 wath a solution of 1 lb. of laundry soap in 4 gals, of soft water, directing 

 the spray on to the under-side of the leaves. If sprayed with clean 

 water a few days later, the sooty mould will Avash off. Badly infested 

 trees may require a repetition of this treatment. 



Experiments are to be made in controlhng A. woglumi AA^th the 

 Coccinellid beetle, Delpluistus catalinae, Horn, which is to be imported 

 into Jamaica from California. This insect is being used to control 

 the citrus whitefly [Dialeurodes citri] in California and Florida. 

 Another Coccinellid, Lioscymnus diversipes, Ch., which is a native of 

 Jamaica, already preys upon A. woglumi.
