512 MR. J. H. LEECH ON THE [NoV. 19, 



All the markings are subject to slight modification but the m- 

 shaped mark referred to by Mr. Butler in his description of this 

 species varies considerably : thus in two examples the extremities 

 alone remain distinct and these are connected by a very fine dark 

 line ; in another specimen the mark is replaced by a large quadrate 

 black spot, and in a fourth the bar is contracted in the middle so that 

 it forms two triangles whose apices are contiguous.

A fine series, coll. Pryer. 



The majority of the specimens are larger than European T. munda. 

 The series includes one example of the var. immaculata.

Several specimens, coll. Pryer. 



There appears to be a pale form and a dark form in Japan as in 

 Europe, but the palest Japanese specimen I have is not quite so light 

 as some of my European examples ; whilst, on the other hand, I have 

 not yet seen a specimen from Europe as dark as the darkest Japanese 

 example in Pryer's series of T. gracilis. Butler's figure of T. ella 

 represents a specimen which as regards tone of colour is intermediate 

 between the two just adverted to.

Five specimens, coll. Pryer. 



Four of these Japanese examples are larger than any European 

 specimen I have seen of T. instabilis, but the fifth is of the normal 

 size. In colour all the five specimens are pale, but I have an example
