to another type-specimen, a large female ; ground colour 

 equally rich with the above, but the two light costal patches, 

 which are very small and dark in the others, are large and 

 light in this type, and the dark markings are large and 

 intensely black ; the central costal and the inner marginal 

 blotches are both continued to the medial or discoidal nerve, 

 where they meet and form a distinct central wavy or incurved 

 fascia ; the two discal spots large, round and distinct ; the 

 outer margin and cilia dark ; blue spots on superior wings 

 almost obsolete, whilst on the inferior wings they are better 

 defined ; the apical white spot small and narrow, suffused 

 with dark scales, whilst the inner blotch-like patch, scarcely 

 seen in the two specimens above, is, in the specimen under 

 consideration, brightly and largely defined ; and this light 

 colour is strongly developed upon the under wings. Hitherto 

 I have only spoken of specimens which are regularly marked 

 alike on each side ; but we now come to the singular speci- 

 mens named above. One of these, a female, has the dexter 

 or right-side superior wing slightly suffused upon the disk ; 

 all the nerves dark ; the outer dark marginal striga broad, 

 especially near the apex, where it widens out so as to take in 

 the outer costal dark blotch and through this broad part. 

 Distinctive characters : the two discal spots and the light 

 suffused blotch upon the outer edge of the lower dark blotch, 

 and at the upper edge of the dark portion of the under wings 

 obtains a greater intensity of brightness in its colours ; 

 for as yet these are the only characters I have seen in which 

 it differs from V. Ichnusa of our continental collections: they 

 are said to vary in shape, &c., but as V. Urtica3 differs in 

 shape also, this assertion does not count for much ; but this 

 is not the question for this paper; 1 therefore merely record 

 the following forms in my collection, and leave to others 

 raore able a question 1 am so unprepared to discuss : — One 

 large female, measuring two inches and one-eighth ; brilliant 

 colours ; every character upon it well defined, except the 

 two discal spots, one of which is obliterated and the other a 

 small lunule, on both wings ; the outer marginal striga is 

 narrow, and vandyked round the blue lunules on the upper 

 portion of the upper wings ; lower down it is only a dark 

 streak-like mark, but upon the lower wings it is broad, dark, 

 and contains within it a series of six of the largest blue
