176 THE ENTOMOLOGIST. 



and one small crescent-shaped mark next the costal margin ; 

 the central and hind marginal streaks are entirely wanting. In 

 two or three specimens the ground colour of the under side is a 

 rich golden green, very different from the pale blue green under 

 sides of my Hungarian specimens, which are all heavily streaked 

 with silver ; the latter are decidedly larger than the Corsican 

 examples, and of course not nearly so dark. 



A few days later and we were back again at Vizzavona. Here 

 things had certainly advanced in our absence. A. elisa of both 

 sexes was now very common all round Tattone, but not out yet 

 at Vizzavona itself. Amongst the chestnut trees or in the hay- 

 fields near Tattone station fine fresh Satyrus circe were quite 

 common, and S. neomiris was frequent ; while on the yellow 

 spartium — which looks so much like broom but isn't — L. hceticus 

 was by no means rare, and occurred up to Vizzavona station. 

 Near here also we frequently took odd specimens of the fine 

 form of C. argiolus var. parvipuncta. Our beautiful purple 

 field of knapweed and mallow had been ruthlessly mown, and 

 the butterflies had disappeared; but hosts of still fresh 

 P. cardiii and E. var. hispulla were abundant amongst the 

 bracken further up; and C. edusa, with no var. helice, raced 

 over the little flowery patches ; and before we left odd examples 

 of D. paphia were secured, for it was just beginning to come out 

 on July 18th. These paphia and those which we took at Corte 

 all incline very considerably to var. irninaculata. I took none 

 that could be considered type, and in many cases there is no 

 trace whatever of silver on the under side of the hind wings. 

 One or two specimens of var. valezina also have no sign of silver 

 markings, but are of a very rich green all over. 



We had naturally been always keenly on the look-out for 

 Papilio hospiton, and had searched miles of country all round 

 Vizzavona and Tattone for larvae, but we never saw a sign of 

 anything approaching either the butterfly or the larva, and I 

 could only suppose that owing to the late season it was not yet 

 out. There was a good deal of a species of fennel growing 

 between Vizzavona and Tattone, which I thought very likely 

 might be the food-plant of P. hospiton, but there were no larvae 

 on any of these plants. When we returned to Ajaccio, I met a 

 French entomologist who lived there, and he gave me a lot of 

 information about P. hospiton. He said it was certainly fully 

 out, and the previous Sunday he had taken four near a village 

 between Tattone and Gorfce, which he considered its headquarters ; 

 but that it was extremely local, and only to be found where its 

 food- plant grew, and that the fennel I had seen at Vizzavona 

 and Tattone was not the one the larva fed on ; in fact it did 

 not grow in that district at all. When I asked him why other 

 collectors had found P. hospiton near Tattone, he said he con- 

 sidered that they were chance examples which had been carried
