GENERAL OBSERVATIONS ON THE GENUS SWAMMERDAJUA. 



8. Conspersella, Tengstrom. rinland, I.-^l.and of Oesel. 



9. Alpicelln, Herrich-Schiitfer, fig. 359 (not Alpicella, N. Scbmett. 



fig. 45, "svliicli is Zcllcria Saxifragce, Staintou). South Gennanr. 



In Dr. Ilerrioh-Scliaffer's collec- 

 tion I saw specimens of a greyer 

 insect allied to Alpicella, which has 

 not yet been named. He took them 

 in the Engadine. Dr. Staudinger 

 also possesses the insect from the 

 same locality. 



The larvic of five of the species 

 are known, three of which feed on 

 plants of the natural order Rosacece. 



I Dans la collection du Dr. Ilcrrich- 

 SchtifFer j'ai vu des individus d'un 

 insecte voisin de V Alpicella, mais 

 plus gris ; ils n'ont pas encore re^u 

 de nom. Dr. Herrich-SchiifFer les a 

 trouves dans I'Engadin. Dr. Stau- 

 dinger a aussi la meme espece de la 

 meme localite. 



On connait les chenilles de cinq 

 especes, dont trois se nourrissent de 

 plantes de I'ordre natural des Ro- 

 sacccs. •

 Prunus spinosa and domestica . . Apicella and Pyrella.

To this I must add that a specimen 

 of Sivammcrdajiiia alpicella was 

 bred by Professor Nickerl on the 30th 

 of April, 1868, from a plant of Saxi- 

 fraga Aizoon, which his sou had 

 brought from St. Ivan, near Prague, 

 the previous autumn. The larva he 

 had not observed, and it is of course 

 just ])ossible that the larva had not 

 fed on that plant, but had only spun 

 up there. I saw both the growing 

 ])]ant and the veritable Swamrncr- 

 damia bred from it. The coinci- 

 dence is very curious, for the larva 



Mais il faut ici ajouter que le 

 Professeur Nickerl a cleve un indi- 

 vidu de la Swammerdamia alpi- 

 cella, le 30 Avril, 1868, d'uue jilante 

 de la Saxifraga Aizoo7i, que son 

 fils avait apportee de St. Ivan, prcs 

 de Prague, I'automne auparavant. 

 II n'en avait pas observe la chenille, 

 et il se pent que la chenille n'ait pas 

 mange cette plante, mais qu'cUe y 

 ait par hasard file son cocon. La 

 rencontre est assez bizarre, parccque 

 la chenille de la Zclleria Saxifraga;, 

 qu'ou a autrefois confondue avec la
