of broods is still an open one, but it can hardly be with such species as 

 Illecta, hisolabilis and many others. 



The eggs were kept through the winter in a room away from any fire, 

 but not allowed to freeze. At the time of hatching the temperature was 

 about that of the open air. At this time the oak buds had scarcely begun 

 to swell. These were cut open and the young larvae ate readily of the 

 interior, and in doing this showed a trait not noticed before in the genus. 

 Instead of eating the edges of the folded leaves I had flayed up for that 

 purpose, they bored into the centre of the buds, as often beginning on the 

 outside scales as where there were cut places, and this they continued to 

 do till the leaves had begun to expand. When the larvae were two inches 

 long the leaves of Quercus coceinea were only one inch long. I had 

 before found larvae of this species in the woods of this size, when the 

 leaves were no further developed, and could not understand why they 

 should be nearly ready to pupate when the leaves were only just coming 

 out, but this trait explains it. They hatch during the first warm days of 

 spring, when the buds begin to swell, and play the part of borers in these 

 buds till the leaves are sufficiently expanded to enable them to eat from the 

 edges of the leaves. 



CETHERONIA REGALIS, Hubner. 



BY FREDERICK CLARKSON, NEW YORK CITY. 



On the 22nd of August, 1882, while entomologizing along the border 

 of a wood at Oak Hill, New York, I was agreeably surprised by a call 

 from a lady companion — an earnest devotee of the floral kingdom, who 

 was but a few yards distant in the pursuit of her favorite study — that she 

 had discovered something which she appeared to regard with that sort of 

 honor which one might bestow on a venemous reptile. Knowing her dis- 

 like of all crawling things, I at once conjectured that the cause of the 

 alarm was a spinous caterpillar, and that my attention, no, doubt, was 

 being directed to that over which I at least would be enthusiastic. It 

 proved to be the formidable looking larva of this moth, popularly known 

 as the Hickory Horned Devil, and on account of its rarity, a goodly, and 

 in no sense an evil sight to a naturalist. It was found feeding on the 

 hickory. It burrowed a few inches into the earth on the iQth of Sep-
