FOR SALE, ITALIAN RHOPALOCERA. 



, I possess many thousand Bhopalocera collected by me on the mountains of Central 

 Italy, and I offer sample series of 50 specimens, all different from each other, at the rate 

 of 8s., free of packing and carriage. 



These Lepidoptera are accurately selected amongst the most perfect of the large series 

 I possess, and are contained in transparent papers. With each specimen is included a 

 small printed label with full data concerning locality of capture. These papers are mailed 

 in a strong box. 



In each one of these lots are included several species peculiar of the Italian fauna : 

 F. mamii, A. pandora, E. neoinins sibyllina, S. seinele aristaeus, S. neomiris, C. corinna 

 elbana, A. escheri splendens, A. thersites, A. coridon apennina, A. aragonensis florentina, 

 L, dolus virgilis, C. lefebvrei, &c. 



I sell these splendid specimens of select species at such a low rate because I do not 

 intend to make a bargain of it, but I simply intend getting the strictly necessary means 

 of continuing my entomological research work in Italy, notwithstanding the difficulties of 

 the present moment. 



Payment in advance is not expected, and the lot will be sent on approval.
