white spots run three shining orange transverse bars, and there 

 is a spot of the same colour on the costa near the base. The 

 hind-wings are white, with a broad blackish marginal band. 

 The body is steel-blue, with six white spots on the thorax, and 

 the legs are black, with white marks. 



There are several closely allied forms, which may or may 

 not be distinct species.

This is a genus which is included in the Exapatidcz by some 

 authors, while others place it in the Tmece, or treat it as belonging 

 to a distinct Family. 



The head is hairy above ; the palpi are small, and the 

 proboscis is almost obsolete. Ocelli present. The female has 

 rudimentary wings. In Diurnea, the ocelli are small, the face 

 and palpi are clothed with smooth hair, and the fore-wings of 

 the female are oval, and as long as the body, the hind-wings 

 being shorter and narrower.
