3526. Abraxas irrorata, Moore, P. Z. S. 1867, p. 652 ; C.&S. no. 3734. 



Pale yellow, irrorated with black ; abdomen with a dorsal and 

 two pairs of lateral black spots. "Fore wing with traces of orange

 Abraxas germana, Smnh. Trans. Ent. Soc. 1891, p. 143. 



Differs from irrorata in being much brighter yellow and more 

 thickly irrorated with black ; fore wing with no antemedial orange 

 band ; the ante- and postmedial dark bands and the postmedial 

 band of hind wing prominent in luteolaria, obsolescent in germana. 



One specimen is much suffused with fuscous.

Ground-colour orange, almost entirely suffused with fuscous in 

 the form poliaria in both sexes ; in crocearia the orange is more 

 developed, and becomes the dominant colour in the female. Fore 

 wing with indistinct spot at end of cell ; medial and submarginal 

 lines, the latter sometimes crenulate. Hind wing with traces of 

 medial and submarginal lines, strongly developed in the female 

 crocearia.

3529. Abraxas diaphana, Warr. P. Z. S. 1893, p. 393. 



Differs from irrorata in the wings being entirely suffused with 

 fuscous, so that there is hardly a trace of the yellow ground- 

 colour on the markings.
