 to learn in what condition or at wiiat stages the winter is passed and 

 whether all caterpillars l)chuve alike. Nothing is known of the chrysalis, 

 excepting that Mr. Saunders reared it the same season from caterpillars 

 produced from eggs laid in June ; the flight of tlie butterfly is undescribed 

 and any parasites of the insect are unknown.

Imago (60: 5). Head large, heavily clothed with rather short hairs, arranged in 

 long transverse masses ; just outside of the antennae a small, spreading, compressed 

 tuft of arcuate hairs, passing generally but one-fifth, occasionally more than one-fourth, 

 way around the eye. Front protuberant, tumid, wholly and considerably surpassing 

 the front of tlie eyes, pretty regularly and considerably arched both transversely and 

 longitudinally but slightly flattened in the middle; shallow, obliquely longitudinal sul- 

 cations occur on either side in front of the inner edge of the antennae ; the whole piece 

 from two and a half to three times as broad as long, the front border delicately mar- 

 gined and in the middle slightly and roundly excised, the outer anterior angles very 

 broadly rounded off; separated from the vertex by a slight shallow sulcatiou, nearly 

 straight, but barely inclining backward at the extremities where it ends in the middle 

 of the antennae. Vertex rather tumid, slightly or considerably elevated above the 

 level of the eyes, sometimes throughout, but generally on the anterior half only, and 

 sometimes with a distinct, transverse, median ridge; scarcely arched transversely, 

 separated from the occiput, which is scarcely sulcate longitudinally in the middle, by a 

 slightly impressed, brace-shaped line. Eyes large, pretty full or full, nearly circular, 

 naked. Antennae inserted with their hinder edges in the middle or scarcely behind 

 the middle of the summit, separated from each other by from three to nearly four 

 times the diameter of the basal joints, the whole antenna slightly or a little shorter 

 than the abdomen, composed of from forty-two to fort}'-fonr joints, of which from 

 seventeen to twenty-two form the club which, although always containing as many
