Geni's salpinx Hubiier. 



14. S. bouruana Moore, Proc. Zool. Soc. Lond. p. 302 (1883). 



This is the local race! of S. nemertes Hiibner, which is apparently not at all 



niicommon upon the island. There is a large series of specimens, both malt', and 



J'eiH'ile, \n wliich there is yreat diversity in size as well as in raaculation. Some 



small miles, apparently starvelings, are one-third smaller than others. Some of 



the females also greatly exceed others in expanse of wing. The snbmarginal spots 



on the upperside of the wing, and the conspicuous blue spot between veins 1 



and 2 on the primaries, vary very much in some specimens, revealing a strong 



tendency to become snffnsed with white and to spread. 



Genus STICTOPLOEA Bntler. 



15. S. watsoni Moore, Proc. Zool. Soc. Loud. p. 322 (1883). 



There is a small series of this fine insect. The female is much like the male 

 in her markings, only varying structurally. 



Genus HAMAURYAS Boisduval.

Moore in his monographic revision of the Enploeina, which is cited above, 

 states distinctly tiiat this genns is without a " sexual mark," or scent-producing 

 organ on the forewing of the male. With this I am compelled to disagree. In 

 the species before me, and in fact in all the other species accessible to me in 

 my collection, //. zoilas (Fabr.), //. aequirincta Salv. & Godm., and //. nedusia 

 (Hiibn.), the males are cliaracterized by the presence on the inner half of the 

 wing of a large tract of a modified scales, having well-defined limits and visible 

 to the naked eye as lighter-coloured areas. These patches of modified scales 

 extend from the inner margin to below the cell, and outwardly towards the 

 external margin, which they never, however, reach. Under the microscope these 

 tracts reveal that the scales upon them are elongated, and dift'er from the scales 

 upon the rest of the wing, which are ])revalently more or less orbicular. The 

 figure given by Cramer of this sjjecies is undoubtedly that of a female. The 

 males are not only characterized, as I have just i)ointod out, by the broad patch 

 of androconia on the primaries, bnt by the much smaller size of the snbajiical 

 spot on the primaries, which is not simply less in area than in the case of the 

 female, but tends to translucency, giving the wing a duller colour than is the 

 case in the opposite sex, in which the clear white contrasts boldly with the deep 

 black of the rest of the surface. 



The collection contains a large series of specimens, for tlie most part in good 

 condition.
