HESTIA. 13 



indistinguishable on a superficial examination ; and it is believed that these 

 species share, more or less, in the immunity from danger, of the Butterflies 

 which they resemble. It is not uncommon for the female only of the 

 mimicking species to resemble its model, the male being totally different. 



The DanaincR are also remarkable for the possession of masses 

 of raised scales on various parts of the wings of the males. In the 

 species allied to Euploea these usually consist of "brands, "or long 

 dark streaks on the fore-wings, and a large patch on the costa of 

 the hind-wings. In those allied to Danaus they usually consist 

 of a patch of raised scales on the disc of the hind-wings. These 

 tufts conceal the peculiar scales formerly called "plumules," 

 but now "androconia,"and are scent-producing organs. They 

 are, of course, secondary sexual characters, and probably not 

 protective, except, perhaps as a casual subsidiary function. 

 These scaly patches are not present in the males of every 

 species, and of late years these Butterflies have been divided 

 into a great number of genera (which we have no space to 

 notice in detail), according to the presence or absence of these 

 sexual markings, combined with differences in the neuration, 

 &c., and the number of fleshy filaments in such of the larvae 

 as are known. But most of these sections are at present re- 

 garded as groups, rather than as genera, by the majority of 

 entomologists.
