 long ago as a parasite on wood-eating beetles. 



Iclinenraon Puparum, Lin. This is the well-known Ptero- 

 malus Puparum, which introduces its eggs to the recently- 

 formed chrysalis of a butterfly; and has been lately well 

 received in North America, as a remedy to the encroachment 

 of Pieris Rapae. It was probably there in pre-hisloric times, 

 but has now the means of making itself known.

Notes on Swiss Lepidoptera. By Henry Chas. Lang, Esq. 



The following is an account of the results of twelve days 

 collecting in the Bernese Oberland; also in the district 

 bordering on the Lake of Lucerne, and the pass of St. 

 Gothard. My time was very limited, these observations only 

 extending between the 9ih and 2-2nd of August, 1871, during 

 a short slay in this part of Switzerland. Circumstances also 

 prevented me from doing exactly as much as 1 pleased with 

 the Lepidoptera. My observations are, therefore, chiefly 

 confined to the diurnal species, and these of course princi- 

 pally butterflies. However, these notes may have some 

 interest, as they show what may be seen in a short time on 

 an ordinary walking tour. 



From the 9th to the 12th of August I employed the time 

 in collecting near the shores of the lake, and in some of the 

 lower forests of Mont Pilate. In the lower ground the most 

 widely-distributed butterfly was Colias Hyale, which was 

 much more abundant than its congener C. Edusa, though 

 this occurred with its light var. C. Helice. 



Generally distributed in the fields, &c., were P. Machaon, 

 G. Rhamni, P. Rapae, Napi and Brassicae, P. Megaera, 

 E. Janira, C. Pamphilus, P. Cardui, V. Urticae and lo, 

 A. Lathonia, L. Alexis and Tiresias, and Chrysophanus 

 Dorilis. More locally in the lower districts and chiefly con- 

 fined to the woods — Leucophasia Sinapis, P. Egeria, S. 

 Semele, A. Paphia, M. Dictynna, P. Sylvanus and Linea. 



In the more elevated woods, in addition to some of those 

 just mentioned, I found M. Galatea, E. Medea, Ligea and 

 Euryale, P. Maera, Argynnis Ino, Adippe and Aglaia, S.
