 niella. 



In the same year, Douglas de- 

 scribed, in the " Proceedings of the 

 Entomological Society of London," 

 an Elachisfa occult ella, which appears 

 identical with Zeller's Humilis. 



The following year, in the " Sup- 

 plementary Catalogue" of Stainton, 

 three new Species (Consortella, Jd- 

 scitdla and Eleocharklln) are described 

 in the body of the work ; and four 

 others {Abbrexiatdla, Rectifascidla, 

 Ext.nsella and Rudcctdla) in the 

 «' List of Tineidffi obtained from 

 Herr Mann," in the Appendix. 



In the " Entomological Transac- 

 tions," vol. ii. (new series published 

 in 1854), Douglas gave the natural 

 histories of three species of this 

 genus {Megeddia, Cygnipenndla and 

 Siibnigrella), the latter being then 

 new to science. For the first dis- 

 covery of the habit of the larva we 

 are indebted to Mr. Logan; my own 

 experience of the laivje commenced 

 on the 20th March, 1853, and as- 

 sisted during that season by Messrs. 

 Douglas, Scott and Wing, a consi- 

 derable number were investigated in 

 the course of the years 1853 and 

 1854. 



In Stainton's volume of the " In- 

 secta Britannica," after deducting 

 the double entries caused by the 

 sexes of some species being de- 

 scribed as distinct, we find no less 

 than thirty-three species of the true 



La meme annee Douglas a decrit, 

 dans les " Proceedings of the Ento- 

 mological Society of London," une 

 Elachista occulldla, qui parait iden- 

 tique avec la Humilis de Zeller. 



L'annee suivante Stainton, dans son 

 " Supplementary Catalogue," decrivit 

 trois nouvelles especes (Consortella, 

 Adsc'itella et EleocharieUa) dans la par- 

 tie principale de I'ouvrage, et qnatre 

 autres (^AbbreTiatdla, Rectifascidla, 

 Ejc ten sella et Rudtctella) dans I'Ap- 

 pendice, oii il donna " une liste des 

 Tineidce obtenues de M. Mann." 



Dans les " Entomological Trans- 

 actions, vol. 2, new series," publics 

 en 1854, Douglas raconta I'histoire 

 ncturelle de trois especes de ce 

 genre (la Megcrlella, la Cygnipennella, 

 et la Subnigrdla), dont la derniere 

 fut alors nouvelle. Nous devons a 

 M. Logan la premiere decouverte 

 des moeurs des chenilles des Ela- 

 chista; moi-meme j'ai commence a 

 observer ces chenilles le vingt Mars 

 1853, et avec le secours de MM. 

 Douglas, Scott et Wing, je reussis 

 a ramasser un assez grand nombre 

 pendant les annees 1853 et 1854. 



Dans le volume de 1' " Insecta 

 Britannica" de Stainton, si nous re- 

 tranchons les femelles de quelques 

 especes, qui y sont decrites comme 

 des especes distinctes, nous trou-
