T. Brrmla, Doubl., ITcw. — This species, wliicli appears to be very 

 common in Japan, was originally described from Western Africa. It 

 is very variable in its appearance, the hind marginal border sometimes 

 presenting a well-marked sinus, as in T. Ilecnhe, which in other cases 

 the sinus is almost (or quite) obsolete. I am inclined to think that 

 it is a form of the extremely variable and w'idcly distributed T. 

 Ilecahe, L. 



Gonepteryx rJinmni, L. — I have only seen a single (damaged) speci- 

 men of this insect from Japan. 



Pieris Melete, Men. — " Varies considerably " (H. Pryer). 



Ghrysoplianus pJdcects, L. — The dark form (C. Timeus, Cram., 

 Eleus, Fab., chinrnsis, Feld.) is only the summer brood of this species. 



Lycmna Argiades, Pall. 



L. Argia, Men. — I think that I have rightly determined the spe- 

 cimens which I have referred to this species, though they all differ 

 slightly from Menetries' figure and description. The $ especially 

 seems liable to vary. In all the specimens which have come under my 

 observation, I notice the following points of difference from the 

 typical L. Argia : on the under-side of the anterior wings there is a 

 minute spot below that within the cell, and another on the costa between 

 the first and second sub-costal nervules ; on the posterior wings there is a 

 spot on the inner margin near base ; none of these arc noticed by Mene- 

 tries. Above these are six (sometimes seven) marginal dots on the hind- 

 wing instead of five. I do not, however, consider these small differences 

 as of specific value. The insect seems common about Tokohama.

Alls supra dilute ccEnileis, poslice brunneo-maryinalis : suhtus cinereis, nijro-

Allied to L. Argia, Men. 



$ . Wing8 above rather dull blue, with a narrow brown border (o hind margin, 

 well defined interiorly. Under-side : wings ash-grey ; fore-wing with a discocellular 

 streak, a spot within cell, another below it faintly indicated, and a transverse row of 

 spots crossing the wing beyond the middle ; all these markings are black, and arc 

 ringed with white. There are two sub-marginal rows of fuscous, rather elongate 

 spots, the exterior very indistinct, and the iinier sufFusedly wliit e margined, especially 

 interiorly. A very fine fuscous marginal lino before the cilia. 



Jlind-iviiiffs : a basal row of three spots, a diseoeelluhir streak, and a curved and 

 angulated row of eight spots beyond middle ; all these black, ringed with white. A 

 double liind marginal row of indistinct fuscous luiiules. Fi'ingc dirty white.
