1. Z. aesculi, Z. ; pyrina, Stand. Cat. — Expanse, male 

 2 inches, female 2f. Thorax and wings white, with numerous 

 blue-black spots. 



Antennas black, in the male with long pectinations at the 

 base and to the middle, thence decreasing in length rapidly 

 so as to round off beyond the middle, from which point the 

 remainder is threadlike and curled up. Face black ; top of 

 the head white, downy ; thorax densely covered with white 

 downy scales, and having on its dorsal surface six large oblong 

 black spots arranged in pairs ; abdomen elongated, rather 

 narrow, dark grey, with thick, soft, whitish scales. Fore- 

 wings long and rather narrow, having the nervures stout and 

 prominent, margins nearly straight, or very gently rounded, 

 apex and hind margin much rounded ; semi-transparent, 

 white with the extreme costal and dorsal margins faintly 

 tinged with brown, the whole surface between the nervures 

 irregularly covered with small indistinct blue-black spots, a 

 larger, and more distinct, similar spot at the termination of 

 each nervure along the hind margin, and a row of the same 

 along the costal and dorsal margins. A small patch only, 

 near the costa and beyond the middle of the wings, is devoid 

 of spots. Cilia white, so short as to be scarcely perceptible. 

 Hind wings rather short, semi-transparent, white with faintly 

 brownish nervures, black spots along the hind margin at the 

 tips of the nervures, and the surface between them sprinkled 

 with small faintly blackish spots. Female much larger, often 

 more than double the size of the male, and with the wings
