GENERAL OBSERVATIONS ON THE GENUS COLEOPHORA. 



Up to this time not more than 16 

 species had been enumerated by any 

 one author ; but, in the " Isis" for 

 1839, Zeller, in his genus Coleo- 

 phora, enumerated 31 species, 11 of 

 which were then described for the 

 first time ; ten years later appeared 

 the 4th volume of the " Linnaea 

 Entomologica," in which 220 pages 

 were devoted to the descriptions and 

 observations of the habits of the spe- 

 cies of this genus, the number of 

 which was now swollen to 105 ; the 

 impetus given by this treatise to the 

 study of this group was very great. 

 Descriptions of a few new Sicilian 

 species had previously appeared in 

 the " Isis" of 1847 from the pen of 

 the same author, and the natural 

 history of one species, Ballotella, 

 had been given by Fischer von Ros- 

 lerstamm in his magnificent work ; 

 but 38 species were described in 

 this volume of the " Linnaea Ento- 

 mologica" for the first time. 



In Eversmann's " Fauna Volgo- 

 Uralensis" nine species are enume- 

 rated, but no new species are de- 

 scribed. 



In the year 1848 Heeger had 

 described with great minuteness a 

 small new species of this genus 

 under the name of Saponariella, and 

 the previous year there had appeared 

 Tengstrom's " Bidrag till Finland's 

 Fjaril-Fauna," in which Incanella, 

 Therinella and Annulatella, and pro- 

 bably several other new species, were 

 described. 



Jusqu'a ce temps aucun auteur n'a- 

 vait enumere un plus grand nombre 

 que seize especes, mais dans P"Isis" 

 de 1839, Zeller rapporta a son genre 

 Coleophora 31 especes, dont onze 

 furent alors decrites pour la pre- 

 miere fois ; dix annees plus tard a 

 paru dans le quatrieme volume de la 

 " Linnaea Entomologica" une mono- 

 graphie de ce genre par Zeller, dans 

 laquelle 220 pages furent consacrees 

 aux descriptions et aux observations 

 sur les mceurs de ces insectes, dont 

 le nombre fut maintenant augmente 

 a 105 ; l'impulsion que cette mono- 

 graphie donnait a l'etude de ce genre 

 fut tres-sensible. Quelques descrip- 

 tions d'especes Siciliennes avaient 

 deja ete publiees dans 1' " Isis" de 

 1847 par le meme auteur, et l'histoire 

 naturelle d'une espece, la Ballotella, 

 avait paru dans Fouvrage magnifique 

 de Fischer von Roslerstamm, mais 

 38 especes se trouvent decrites pour 

 la premiere fois dans le quatrieme 

 volume de la " Linnaea Entomo- 

 logica." 



Dans la " Fauna Volgo-Uralensis" 

 d'Eversmann neuf especes sont enu- 

 merees, mais aucune espece nouvelle 

 n'est decrite. 



Dans l'annee 1848 Heeger a decrit 

 dans 1' " Isis" avec beaucoup de de- 

 tail une petite espece nouvelle sous 

 le nom de Saponariclla, et l'annee 

 precedente a paru le " Bidrag till 

 Finland's Fjaril-Fauna" de Teng- 

 stiom, oii 1' Incanella, la Therinella 

 et YAnnulatella, et peut-etre quelques 

 autres especes nouvelles, se trouvent 

 exposees.
