 Butl. Cat. Fabr. t. iii. fig. 6. 



It is difficult to understand the group of species of which I take 

 this as the type. They are numerous and variable, and their syno- 

 nymy and distribution most puzzling. A number of supposed species 

 are included in Hewitsou's and other collections under the name of 

 P. mathias, which, if I have rightly identified it, has a group of 

 transparent spots on fore wing and on the hind wing a group of 

 small ones which do not show on the upper surface. 



I have seen it from Shanghai (Pri/er) and from Japan. 



P. lamprospilus. 



Isoteinon lamprospilus, Feld. Wieu. ent. Mon. vi. p. 38 (1862). 



Pamphila vitrea, Murr. Ent. Mo. Mag. 1875, p. 171. 



I believe this identification is correct, though I have not seen 

 Chinese specimens. It is described by Felder from Ningpo, and 

 seems common in Japan. It is distinguished by a group of large 

 transparent spots showing through the fore wing, and by nine small 

 ones showing only on tlie underside of the hind wing. 



? P. OCEIA, Hew. Desc. Hesp. p. 31 (1868). 



An insect so named in Pryer's collection from Shanghai does not 

 agree with Hewitson's description. 



It is of the size and shape of P. mathias, with eight transparent 

 spots on the fore wing and a black tuft of hairs on the ceatre of 

 hind wing, but no spots. 



P. oceia is described from the Philippines. 



P. VARIA, Murr. Ent. Mo. Mag. 1875, p. 172. 



This species is known by the colour of the underside, which is 

 ochraceous with darker veins. It seems common in Japan ; but I 

 have seen no specimens from elsewhere. 



P. guttata. 



Eudamus guttaius, Brcm. & Grey, Schmett. ndrdl. China, p. 10 

 (1855). 



Gonoloba guttata, Men. Cat. Mus. Petr. t. v. fig. 4 (1857). 



Common in Japan. Found also at Shanghai (Pryer) and Pekin 

 (^Bremer). 



It belongs to the grouj) of olive-coloured Pamphilce having trans- 

 parent spots on the fore and hind wings. 



P. fortunei, Feld. Reise Nov. t. 72. fig. 11. 



From Shanghai. I have not seen this; but, judging from the 

 figure, it is very near P. guttata. 



P. PELLUCIDA, Murray, Ent. Mo. Mag. 1875, p. 172. 



Very near the last ; but distinguished by the spots of the hind 

 wing being arranged in an alternate line instead of a straight row
