NOTES ON JAPANESE BUTTEEFLIES, WITH DESCRIPTIONS OF NEW 

 GENERA AND SPECIES. 



BT THE EEV. E. P. MUEUAT, M.A. 



The insects to whicli the following observations and descriptions 

 refer were collected by Mr. H. Pryer, mostly in the immediate neigh- 

 bourhood of Yokohama. 



Papilio Deliaani, Feld. — This species, which is probably not dis- 

 tinct from P. Manckl, Men., appears to be not very uncommon, but, 

 from its strong and rapid flight, is difficult to obtain in good condition. 



P. Demetrius, Cram. 



P. Alcinoiis, Klug. — There are two forms of this species, one 

 black, the other fawn colour (P. Mencius, Feld.). 



P. Sarpedon, Linn. 



In addition, Mr. Pryer takes the following species : P. Macliaon, L., 

 Xuthus, L., " ^uthuUnus^^ (? Xuthuliis, Brem.), and Pammon, L. 

 He sends me the following note on P. Xuthulinus : " I believe XutJiu- 

 " linus to.be a stunted form of Xuthiis : the larva and food-plant are 

 " the same, and very strangely, XuthuJiniis is the only single-brooded 

 " Papilio we' have here, appearing very early in the year ; the larva? 

 " feed up very rapidly just as the leaves are going off the trees in No- 

 " vember, so the question naturally arises, what becomes of them from 

 "April to November? I think the small size is caused by bad and 

 " insufficient food : if I can get time, I will endeavour to breed them 

 " from the egg next spring." 



Parnassius glacialis, Butl. — Two specimens from " Neko, about 

 100 miles north of Tokio." The species does not seem to occur on the 

 mountains near Yokohama. 



Anthocaris Scolymus, Butl. 



Colias Hijale, Linn. — I have not seen specimens from Japan. 

 Mr. Pryer states that it is extremely abundant both on the plains and 

 the mountains. 



Terias Iceta, Boisd. — I am inclined to think that the insect de- 

 scribed by Mcnetries as T. Jcegeri is the Japanese form of T. Iceta. 

 Certainly the specimens in my collection agree closely with his de- 

 scription and figure. 



T. Mandarina, De I'Orza. 



T. Hccahe, Linn.
