CURRENT NOTES. 313 



the author himself. The famihes contained in the first two 

 vokimes of Lethiery and Severin's Catalogue, and about two- 

 thirds of the third — in fact, the most recent — 17th — part, com- 

 pleting the Keduviidfe down to the end of the Nabinae — are dealt 

 with. Walker fortunately described comparatively very few 

 Miridae, and practically no Cryptocerata, so that, although the 

 museum collections are very rich in some of these forms, we 

 may hope to see very soon the completion of the Heteroptera, 

 and with the commencement of the Homoptera, in the Cicadidae, 

 the author falls upon one of his favourite families. 



Among other recent contributions to entomological literature, 

 which I can unfortunately notice very briefly, are : — 



11. L. Zehntner : "Rapport over de mottenbestrijding of 

 de Onderneming Banaran, 1901-1902," Proefstation voor Cacao 

 te Salatiga, no. 5, Niewe Gids iv. afl. 11 and 12, pp. 1-53, with 

 a graphic chart for twelve ensuing years ; Apl. 1903. This 

 discusses fully the depredations of the lepidopteron Zaratha 

 cramerella, Snellen, on the cocoa plantations of Java. 



12. N. Banks : " An Index to Bulletins 1-30 (new series) 

 (1896-1901) of the Division of Entomology," U. S. Dep. Agr. 

 Div. Entom. Bull. 36, n. s. (1902). The accuracy and usefulness 

 of these indexes are indisputable ; a slight improvement would 

 have been the recapitulation on one page of the titles of each of 

 the bulletins. 



13. C. M. Weed & A. F. Conradi : " The Whitefly of Green- 

 houses," Bull. 100, N. Hampsh. Coll. Agr. Exp. Sta. pp. 45-52, 

 figs. ; March, 1903. An account of a species of the rhynchotal 

 genus Aleurodes ; its life-history, depredations, and control by 

 hydrocyanic acid gas. 



14. G. Del Guercio: "Contribuzione alb studio dei Diaspini 

 deir olivo," Bull. Soc. Ent. Soc. Italiana, xxxiv. pp. 179-188, 

 ten text figs. (Mch. 20th, 1903). A study of certain Coccids of 

 the olive [Pihynchota] . 



15. A. DucKE : " As especies paraenses do genero Euglossa, 

 Latr." [Hymen.], Bol. Museu Paraense, iii. 561-79, plates; 

 Dec. 1902. The bulletin of this museum contains periodical 

 bibliographical notices of works relating to South America. 



16. P. Chretien: " Les Erebia de France" [Lep.] , Le 

 Naturahste, xxv. pp. 71-2 (15th March, 1903). Twenty-one 

 species credited to France. 



17. H. M. Lefroy: "Scale Insects of the West Indies," 

 West India Bull. iii. pp. 240-70 and 295-319 [Rhynch.] . The 

 Coccidse of the Lesser Antilles (St. Lucia, St. Vincent, Guade- 

 lupe, &c.) are discussed ; the region being thought to represent 

 a "fairly definite zoological area." 



18. L. Eeh : " Biologisch-statische Untersuchungen an 

 amerikanischen Obst-Schildltiuse," Zool. Jahrb. xvii. pp. 237-84,
