GENERAL OBSERVATIONS ON THE GENUS ELACHISTA. 



ElachisfdB, four of which were then 

 new. In the ''Entomologische Zeit- 

 ung" for 1853, Zeller described the 

 species alh'ed to C i/gnipennella and 

 Festuckuldla, 



Among the new species obtained 

 by rearing from the larvae must be 

 mentioned Poce and Gregsoni (tlie 

 latter had previously been con- 

 founded with Nigrella), both of which 

 are first described in the " Entomo- 

 logist's Annual" for 1855. In the 

 '* Annual" for 1856, Flavicomtlla is 

 described, and in that for 1857 Tce- 

 niatdla. 



At the close of 1855, Herrich- 

 SchafTer's fifth volume of the 

 " Schmetterlinge von Europa" was 

 completed ; he enumerated sixty spe- 

 cies of the genus, placing them all in 

 his genus Poeciloptilia, with the excep- 

 tion o^ Cijgnipennella, which he formed 

 into a genus by itself {Cycnodia) ; 

 several species were then described 

 for the first time, such as Cingilldla, 

 Incandla, Tetragondla, Grossepunc- 

 tdla and Nitiduldla. 



Herrich-Schafter was the first to 

 remove Pftifferella and Treitschkidla 

 from the other species, forming of 

 them the distinct genus Antispila ; a 

 proceeding which has since very pro- 

 perly been followed by Frey. 



Frey, in his " Tineen und Ptero- 

 phoren der Schweiz," devotes twenty 

 pages to this genus, of which he 

 enumerates twenty - eight species, 

 Hdvetica, Utondluy and the strange- 



et parmi elles quatre nouvelles a 

 cette epoque. Dans V " Entomolo- 

 gische Zeitung" de 1853, Zeller a 

 decrit la Fe&tucicold/a, esp^ce tres- 

 voisine de la Cygnipenndla. 



Parmi les nouvelles especes ob- 

 tenues par I'education des chenilles, 

 il faut citer la Poce et la Gregsoni (la 

 derniere avait ete auparavant confon- 

 due avec la Nigrella), qui sont toutes 

 deux decrites pour la premiere fois 

 dans r " Entomologist's Annual" de 

 1855. Dans 1' " Annual" de 1856 se 

 trouve la description de la Flavico- 

 mella, et dans celui de 1857 celle de 

 la Tceniatdla. 



Vers la fin de 1855 le cinquieme 

 volume des " Schmetterlinge von 

 Europa" de Herrich-Schaffer fut 

 termine, et I'auteur y mentionne 60 

 especes de ce genre, les pla^ant 

 dans son genre Poeciloptilia, a I'ex- 

 ception de la Cygnipennella, dont il 

 etablit un genre a part (Cj/c«0(fia) ; 

 plusieurs especes y sont decrites 

 pour la premiere fois, telles que la 

 Cingilldla^ Ylncandla^ la Tetragonella, 

 la Grossepundella et la Nitiduldla, 



Herrich-Schaffer fut le premier 

 a detacher les Pfeifferdla et Treitsch- 

 kidla des autres especes, pour former 

 le genre Antispila, separation que 

 Frey a bien fait de repeter. 



Dans les " Tineen und Pteropho- 

 ren der Schweiz" de Frey, vingt 

 pages se trouvent consacrees a ce 

 genre, dont 28 especes y sont enu- 

 merees: la Helvetica et YUtondlat
