BOARMID^—ENNOMOS. 59 



sycamore, on which it had probably fed. Feeds principally 

 at night ; by day remains in the stiffly straight position of a 

 large twig. 



Pupa large and stout, holding its abdomen almost con- 

 stantly bent or curved ; colour green, with a superficial 

 coating of white or pinkish-white sculpture in relief, which 

 under a lens appears like most beautiful working, in porce- 

 lain-like material, placed in irregular and cross lines over 

 the front of the thorax, indicating the joints of the limbs and 

 pectinations of the antennae ; also in thick wrinkles between 

 the nervures on the wing-covers ; and as irregular raised mar- 

 gins of the small pitting on the broad bands of the abdominal 

 segments. Although rather coarse this sculpture looks to 

 the unassisted eye much like a powdery bloom or dusting. 

 Segmental folds smooth, green, edged with pink ; spiracles 

 black-brown ; some scattered black dots lie along the edges 

 of the segmental bands ; cremaster deeply wrinkled, elongated, 

 pale pinkish-brown, armed toward the tip with some hooked 

 black spikes which hold firmly to the inside of its cocoon. 

 The latter is extremely slight — a mere network of white silk 

 threads drawing together leaves, but with interstices through 

 which the pupa is distinctly visible. 



The winter is passed in the egg-state. 



In all probability the moth passes the day hanging to a 

 twig in some tree, but very little is known of its habits 

 here, except that both sexes are strongly attracted at night 

 by light, and are usually captured— if at all — at street-lamps. 

 So far as these Islands are concerned, it seems to be confined 

 to the coast of the South of England and almost to the 

 extreme South Coast. Whether it is a frequent immigrant, or 

 that it is only able to exist in a climate little affected by frost, 

 is not yet clearly established. So far as can be ascertained, 

 the first specimen noticed here was taken at the North Fore- 

 land, Kent, before the year 1855; but in that year the 

 capture of two more was announced, one in September, at
