large as rowsus, but the primaries are more triangular 

 and look broader at the termen. In colour it is lustrous 

 violet with narrow dark l)orders. Below it is white with 

 blackish spots, the postmedian and subterminal lines 

 being strongly marked and but slightly interrupted at the 

 veins, the former is sharply turned round (almost angled) 

 at vein 6 basewards to the costa ; in the secondaries the 

 postmedian line is continuous and slightly crenulated, 

 whilst the spots are well separated. I think it would be 

 well to say that T know of no pattern or mark that holds 

 true in a long series of any species in this small genus with 

 the exception of syharis and its allies ; they all seem to 

 gra\ntate towards iheophraslus, whilst theophrastus in its 

 dry-season forms gravitates towards one oi- two of the 

 Indian species such as callinara or exlricatus. I have 

 never experienced such difficulty in separating species 

 as I have done with these. There are only three that I 

 have not made mistakes with even after the utmost care, 

 and had it not been for the very distinctive genitalia of 

 each species, I should have found it quite impossible to 

 decide with certainty what some forms were. In diagnosing 

 the pattern I have picked a good average specimen, but 

 with either the dry or wet season forms the diagnosis 

 will not be absolute. It is fortunate that the genitalia 

 are cjuite distinctive, otherwise it would have been im- 

 possible to say, as we can say now, that Moore's and 

 Butler's eyes served them well and correctly, when, without 

 any knowledge of the reproductive organs, they described 

 the forms they had before them as new species. 



The genitalia (of nnra) are easily separable from its near allies. 

 The clasps are subovate with the iip])er margin slightly flattened, 

 the rounded front edge being furnished throughout with a row of 

 sharp teeth. The horn-like sclerites (virgae excitatae) are wedge- 

 shaped, tapering to a point, and not extending beyond the apex 

 of the clasp. The tegumen is typical of the first section of the 

 genus, being deeply divided with only a narrow connecting ridge at 

 the rear; the falces are shortish and stout. The acdoeagus is also 

 fairly typical of this section, it is moderately stout, shoi'tish, with the 

 front portion beyond the zone suddenly reduced, and rapidly 

 tapering to a point. The clasps are furnished with long strong 

 bristles, and the tegumen with finer and shorter ones. The tectorius 

 is very broad at the base, tapering at its front edge rapidly up to 

 the anellus. The androconia are rounder and shorter and smaller
