forms of Japanese Butterfiies. 489 



three females and one male, are the Mandarina form. I 

 have never captured this form at this season of the year, 

 or even seen anything approaching it, although twenty 

 or thirty of the other forms are now brought in daily by 

 my collector, to whom I have given special instructions 

 to capture as many Terias as possible. Six specimens, 

 five males and one female, are the Hecahe form as figured 

 in the plate, Nos. 1 to 6 ; two specimens, both males, 

 represent figures 7 to 11 ; and one female can also be 

 placed in the same rank. One female would do for either 

 forms, Nos. 1 to 6 or 7 to 11, as it unites both in having 

 a more distinctly marked black edge on the right wing 

 than on the left wing ; the remaining specimen, a female, 

 is quite a new form intermediate between Nos. 7 to 11 

 and 12 to 17. This insect is, therefore, very sensitive to 

 temperature influences, and I believe it is owing to my 

 having reared these specimens in a cold room, without 

 much direct sunlight, that I have been so successful in 

 procuring all these forms from a single lot of eggs. Al- 

 though I am perfectly aware that I shall be charged with 

 perpetrating a serious scientific solecism, still, taking 

 into consideration the exceptionally large numbers of 

 forms of this insect which have been described as distinct 

 species, I venture on proposing yet another name, and 

 uniting all those hitherto described under the name of 

 Terias multiformis.

Terias scnegalensis is given in the Catalogue of the 

 Hewitson Collection, one specimen from Japan. I should 

 like to know whether it can be referable to Terias multi- 

 formis. I have two specimens of a Terias from Singa- 

 pore marked like the Hecahe form, but with fore wings 

 more rounded than the usual Japanese specimens.
