down the back ; the tips of the anal points are 

 pink. It feeds on the common sallow (Salix 

 capraa), and is full-fed about the middle of 

 September, when it spins a slight oval C"coon 

 among the fallen leaver The CHRYSALIS is 

 short, chesnut-brown, and shining; it remains 

 in its cocoon throughout the winter. 



The MOTH appears on the wing in May 

 and June, and has been found in some of our 

 English counties, both northern and southern, 

 but I have not heard of its occurrence in Scot- 

 land ; Mr. Birchall records it from Irelaud 

 on the authority of Dr. Bull, but no locality 

 is given. (The scientific name is Lobophora 

 sexalisata.) 



305. The Seraphim (Lobophora hexapterata). 



305. THE SERAPHIM. The fore wings are 

 long, broad, ample, and of a pale gray colour, 

 with a slight tinge of ochreous in some speci- 

 mens; they have a n tmber of transverse 

 smoky markings, some of which form linear 

 series, while others ate too irregular to de- 

 scribe; the extreme base of the wing is gray, 

 then follows a short and narrow curved smoky 

 bar, both margins of which are darker, then a 

 pale elbowed bar, then a broader smoky bar, 

 then a waved pale line, then an indistinct 

 double smoky line, then a pale transverse 

 space, which contains a small linear black dis- 

 coidal spot; and beyond this the tints and 

 markings are confused and broken, and mixed 

 and interspersed with black arrow-heads 

 placed transversely : the hind wings are small 

 and rounded ; in the male each of them has 

 an oblong lobe at the base, extending nearly 

 half the length of the win;?, and delicately 

 fringed at the margin, so as to ha\e tlie ap- 

 pearanc" of a real wing ; both the hind * ings 

 and their lobes are almost snowy-white, but 



the wings have a slender black line on the 

 margin itself, and an obscure series of dots 

 just within the margin. 



" CATERPILLAR, beautiful green; a sulphur 

 line on each side, and two sulphur points* 

 project from the anal segment ; head with 

 two yellow points (Treitschke). On sallow 

 and aspen, June." Staintoris Manual, ii. 94. 



" Although this species is the commonest 

 of the genus, its caterpillar is not very clearly 

 known; Lyonet has given a very clumsy 

 figure of it, and Treitschke a very brief de- 

 scription. The first-named of these authors 

 does not mention its food-plant, the second at 

 first makes it feed on beech, and afterwards 

 on sallow and poplar." Guenee, Uran. et 

 PhaL, ii. 368. 



The MOTH appears on the wing in June, and 

 occurs in many of our English counties, but I 

 do not recollect seeing it recorded from Scot- 

 land or Ireland. (The scientific name is 

 Lobophora hexapterata.) 



Obs.- ! regret my inability to describe the 

 caterpii.ur of this common moth, but shall be 

 much gratified if the brief extracts given 

 above afford a clue to its discovery. 



306. The Yellow-barred Brindle (Lobophora viretata). 



306. THE YELLOW-BARRED BRINDLE. The 

 fore wings are ample, but not elongate ; they 

 are of a delicate ochreous green colour, which 

 is traversed by slender waved white lines, and 

 decorated with transverse series of black spots; 

 several of these combine in forming a broad 

 band across the middle of the wing, but this, 

 again, is interrupted by a pale median space, 

 in which a slender linear discoidal spot may 

 sometimes be traced; beyond the band is a 

 double series of black spots, and on the hind 

 margin is a single series of double black spots : 

 the hind wings are very pale dingy brown, 

 with the slightest possible trace of a discoidal
