BRITISH MOTHS. 



also a rather large gray spot ; a transverse 

 waved line, not very distinct, crosses the 

 wing before the orbicular, and another beyond 

 the reniform ; these two lines are connected 

 below the lozenge-shaped spot already noticed 

 by a longitudinal black line, somewhat resem- 

 bling the letter I ; at the middle of the base

of the wing is a second black line not so con- 

 spicuous as the first ; beyond the discoidal 

 spots is a gray band, very pale at its lowest 

 extremity, and between this and the hind 

 margin is a zigzag white line, resting on 

 which are several dark wedge-shaped marks, 

 having their points directed towards the base 

 of the wing ; the hind wings are pale gray, 

 slightly suffused with saffron : the head and 

 thorax have the same colour as the fore wings; 

 the body is gray-brown, and crested, the tips 

 of the crests being dark brown. 



The CATERPILLAR rolls in a ring when 

 touched, but soon unrolls itself and commences 

 crawling with great rapidity : the head is 

 shining, and of a dingy green colour reticulated 

 with rufous-brown ; the body is orange-ochre 

 coloured, inclining to rufous on the back, and 

 to dingy yellowish-green on the sides and 

 belly ; the rufous tint of the back is due to 

 reticulated markings, which are crowded and 

 clustered in certain parts, so as to form a 

 series of eleven Vs down the middle, the apex 

 of each V pointing towards the anal extremity ; 

 a narrow and interrupted rufous stripe on 

 each side includes the spiracles. It feeds 

 on the common birch (Betula alba] and oak' 

 (Quercus Itobur), and is full-fed at the end of 

 September. 



The MOTH appears on the wing in June, 

 and although by no means an abundant 

 species, seems to be widely, and I think I 

 may say genei^ally, distributed in England, 

 Scotland, and Ireland. (The scientific name 

 is Iladena contiyua.) 



Obs. The English names of the Hadenas 

 are adapted for the sake of uniformity : I 

 . cannot say that I regard them as either very 

 descriptive or appropriate : the present species 

 for instance is not distinguished from the rest 

 by its greater beauty.

656. THE LIGHT BROCADE. The palpi are 

 inconspicuoxis, the terminal joint small and 

 pointed ; the antennae are simple : the fore 

 wings are beautifully mottled and marbled 

 with various tints of gray and brown ; the 

 orbicular is round and has a .slender black 

 circumscription ; the reniform has not so per- 

 fect, a circumscription ; the median area is gray 

 in both immediately below them is a longi- 

 tudinal blotch of rich dark brown ; at the 

 costal base of the wing is a rather large gray 

 spot, and below this a very distinct linear 

 longitudinal black nwk ; beyond the discoidal 

 spots is a broad pale gray band extending 

 entirely across the wing, and beyond this a 

 pale gray zigzag line accompanied by dark 

 margins and a few dark wedge-shaped mai'ks 

 which point towards the base of the wing ; 

 the hind wings are gray-brown with darker 

 wing- rays and paler fringe : the head is gray : 

 j the thorax is gray and crested ; it has a very 

 I distinct transverse black line on the collar ; 

 the body is gray-brown and crested. 



Mr. Buckler has described the CATERPILLAR 

 from specimens sent him by my friend Mr. 

 Doubleday. He says : " When young the 

 colours of these caterpillars were brighter and 

 darker than they afterwards became, with dis- 

 tinct paler dorsal and sub-dorsal lines outlined 

 with darker and black spiracular lines. When 

 full-grown they were very plump creatures, 

 varying from an inch and five-eighths to an 

 inch and three-quarters in length, cylindrical 

 and tapering towards the head ; the back and 

 sides, as far as the row of spiracles, of very 

 mottled dull brown, brownish - gray, dull 

 greenish-gray, deep purplish-brown, or dirty 

 olive-greenish for all these tints were found 

 in the brood. The dorsal and sub-dorsal 

 stripes are outlined with darker brown, in 

 many instances only visible on the anterior
