often destructive, extending over the greater part of the 

 Continent of Europe, except the extreme north, and into 

 Siberia, Tartary, and a large portion of Eastern Asia. From 

 Japan it is received under the name of testacea Kotze, but 

 agreeing accurately, in both sexes, with our insect. There is 

 also a very similar form found in America, and named Calif or- 

 nica, which, though rather slender, seems doubtfully distinct. 



2. C. castrensis, L. — Expanse of male, 1^ inch, of 

 female, Ih to If. Yellowish-bufF or red-brown, with a 

 central band leading into the base of the fore wings. Hind 

 wings nearly always dark-coloured. 



Antennae of the male rather short and recurved, strongly 

 pectinated, reddish-brown. Thorax broad and squared, abdo- 

 men short and tapering ; both, with the head, densely clothed 

 with long fluffy scales ; pale ochreous, reddish-ochreous, or 

 red-brown ; abdomen browner than the rest. Fore wings 

 short and broad, bluntly triangular ; base narrow, costa 

 straight ; apex bluntly angulated ; dorsal and hind margins 

 regularly rounded; straw colour, pale ochreous, pale buff, 

 reddish-ochreous, or red-brown ; first line reddish-brown, 

 arising in the middle of the costa, and making a wide curve 

 into the base of the dorsal margin ; second line oblique and 

 moderately straight ; between this and the hind margin is 

 usually a line of indistinct reddish or brownish clouds ; occa- 

 sionally the base and middle area of the wings are faintly 

 clouded with the same, but when the wings are of a red- 

 brown these markings are absorbed or very faint ; cilia 

 yellowish, with irregular reddish-brown dashes. Hind wings 

 short, with the hind margin very slightly and flatly rounded ; 

 but the anterior margin is so much arched near the base that 

 a curved-up flap appears conspicuously in front of the fore 

 wings when the moth is at rest. Colour of the hind wings 

 pale, or deep purplish-brown or chocolate, strikingly con- 

 trasted in colour with the fore wings in the lighter-coloured 

 specimens ; a little darker, but less conspicuously so, in the
