Papilio zolicaon is found at all elevations, being smaller in 

 high alpine districts, where it flies in company Avith P. indra. 

 In tliese situations an umbelliferous plant, resembling a wild 

 carrot, is abundant, and doubtless serves as the food-plant of 

 both species. Their flight is high and wild in such situations : 

 often the males of P. indra will rise, buffeting each other, for a 

 hundred metres in the air, descending almost as abruptly, and 

 not infrequently alighting on bare rocks to sun themselves. I 

 took, altogether, nine males of P. indra, but was not rewarded 

 by the capture of a female, although I was very anxious to 

 obtain one to " set " for eggs. 



Of all the Papilios, P. eurymedon was the most abundant, the 

 males often congregating by dozens at muddy places in the 

 road, at moderate elevations, although occasional specimens 

 were met with as high as 2750 metres. P. rutulus was rather 

 less common in similar situations. One female of this species, 

 tied in a large bag upon a branch of wild cherry, laid twenty 

 eggs. The young caterpillars decidedly resemble those of P. 

 turrms, but seem more difficult to raise than that species. Mine 

 died when past the first moult. Mr. Henry Edwards informs 

 me that he has repeatedly found larvas of this species, but inva- 

 riably lost them before they changed to chrysalis. There is 

 more difficulty in obtaining the egg than with P. turnus, for 

 this same female had been confined in a smaller bag with the 

 food-plant for some days previously and had utterly refused to 

 lay. About half a dozen other females of P. 7'utulus were 

 placed in the large bag from time to time, but none of these 

 laid any eggs. Eggs of P. eurymedon were obtained ; they are 

 slightly smaller than those of P. rufulus, and of a clearer, less 

 yellowish green. Under a lens the surface of both is seen to 

 be slightly roughened. 



Parnassiiis clodms I did not meet with, but eight females 

 and one male of P. haldur were taken around the Yo Semite 

 valley late in June, most of them at an elevation of about 

 2100 metres, although two, as before mentioned, were taken 

 900 metres lower down in the valley. The disproportion be- 

 tween males and females is remarkable, for in all other places I
