124 THE ENTOMOLOGIST. 



from B. archesia in having the inner line of the central area of 

 primaries perpendicular instead of oblique (if anything, the 

 direction is from inner margin obliquely outwards to costa) ; 

 the two latter differ chiefly in colouring, and may prove to be 

 one species. Walker recorded four examples from the Navigators' 

 Islands, one of which was a mere wreck, unfit for any collection ; 

 and a second specimen equally bad, and labelled "Cent. Ind.," 

 which was, of course, R. archesia. 



The species into which the abundant and widely distributed 

 Ji. repanda have been split up, simply represent an instance of 

 what has been aptly called " sorting marbles "; all specimens in 

 which a line has faded out have been placed under one name, and 

 all the varying shades have been carefully matched under other 

 names. The fact that the most distinct of the various named 

 sports constantly come together in the same collections, appears 

 not to have raised a question as to their distinctness as species 

 in the minds of their describers, or their successors ; indeed, 

 Guenee indignantly says : — *' On a confondu la Latipes avec la 

 Repanda de Fabricius, qui m'en parait distincte ; c'est de la 

 premiere que parle M. Boisduval dans son Genera, p. 170, quand 

 il cite les pays differents qu'il lui assigne pour patrie, ainsi que 

 M. Dapouchel, qui, dans son Catalogue, ne fait guere que repeter, 

 de confiance, I'assertion de M. Boisduval. Ni I'un ni I'autre ne 

 parait avoir distingue la veritable Repanda, qui semble habiter 

 exclusivement les Antilles." 



On looking at M. Guenee' s description of R. repanda, it is 

 amusing to note the following observation : — " Je n'ai vu que 

 des femelles. Je ne connais pas le male, qui doit avoir beaucoup 

 de rapports avec celui de la Megas." How far this belief was 

 confirmed will be seen by referring to Walker's catalogue under 

 R. latipes, where a male from S. Africa, indistinguishable from 

 St. Domingo males in our collection, is recorded. The type of 

 Walker's R. conveniens, from the Congo, belongs furthermore to 

 the form recognized as R. repanda by M. Guenee. Hiibner's 

 figure, quoted by M. Guenee, is either incorrect, or it represents 

 a distinct species, the undulation of the subbasal line (extra- 

 basilaire) being unlike that of any Remigia known to me. It is 

 tolerably certain to be incorrect.
