JWARM/D.-E—E UR YMENE. 49 



On the wing at the end of May and in June. We seem 

 to have no record of the appearance here of specimens of a 

 second generation, though such an occurrence is usual on the 

 Continent. 



Larva twig-like, the third segment having a considerable 

 dorsal and lateral enlargement, and the second beinir swollen, 

 both being much wrinkled ; ninth also swollen and humped ; 

 anal segment bristly and furnished with two small points ; 

 head rounded and slightly bifid, purple mottled with white ; 

 body yellowish-, greenish-, or pale reddish-brown, mottled with 

 hazel and purple-brown ; from the second to the fourth seg- 

 ment the back is dark purple ; hump on the ninth segment 

 purple, and a purple transverse bar on the twelfth ; spots 

 grey ; spiracles black ; a pair of small raised black ventral 

 spots each on the fifth, sixth, and seventh segments, and 

 sometimes on the eighth and ninth ; there are faint traces 

 of paler dorsal and spiracnlar stripes. (C. Fenn.) The Rev. 

 P. H. Jennings, in an old number of the Entomologid, 

 pointed out that " when at rest, with the mouth tightly 

 pressed to the legs, the first three segments much resemble a 

 miniature dog's head, the head of the larva representing the 

 dog's nose, and the protuberances of the third segment the 

 ears and crown of the animal's head."' Tins cannot well be 

 included among protective resemblances ! but the creature is 

 sufliciently provided for in that respect by its extraordinary 

 likeness to an oak-twig. 



July, August, and September on oak, sallow, beech, and 

 birch. This larva is very much more frequently captured 

 than the moth. 



Pupa rather slender, and very gently and regularly tapering 

 off behind ; eyes and front of the head rather prominent ; 

 wing-covers rough with abundant fine sculptui'e or cross- 

 wrinkling ; limb and antenna-covers more distinctly cross- 

 barred with incised lines ; dorsal and abdominal segments 

 faintly dotted with minute pitting, except those nearest the
