BRITISH MOTHS. 



but delicately outlined in paler olive-gray, 

 and the median area of each being very 

 slightly darker than the general ground- 

 colour of the wings ; there are three slender 

 transverse lines of the same colour as the 

 circumscription of the discoidal spots; all of 

 these are oblique, two of them are nearer the 

 base of the wing than the orbicular, and both 

 these are farther from the body at the costal 

 than at the inner-marginal extremity ; the 

 third transverse line is situated beyond the 

 reniform : the hind wings, head, thorax, and 

 body are very nearly of the same colour as 

 the fore wings; the hind wings have a paler 

 fringe. 



Mr. Hellins, who has described the CATER- 

 PILLAR in the Entomologists' Monthly Magazine 

 for January, 1868, says that when full-grown 

 it is about an inch in length, slightly tapering 

 towards both extremities, and flat beneath ; 

 the head is small, rounded, and rather flat ; 

 the skin is very delicate and thin, so that the 

 stripes on it show as if ribbed or raised, and 

 the internal organs are partially seen through 

 it : the colour is pale dull green, with a 

 yellow tinge towards both extremities; there 

 is a broad whitish dorsp.l stripe, and the 

 slender lateral stripes of the same colour, the 

 latter in the region of the spiracles is waved ; 

 the head is rather yellowish-green or blackish- 

 brown, and occasionally there is a dark collar 

 on the second segment ; the young cater- 

 pillars have the usual dots very visible and 

 black, but lose all trace of them as they grow 1 

 larger: it folds and spins together the leaves 

 and shoots of the sallow (Salix caprea), and 

 resides in the domicile thus formed ; it may 

 be found by opening these retreats at the end 

 of May and beginning of June. 



The MOTH appears on the wing in August, 

 and occurs sparingly in some of our English 

 counties; at Exeter and Alphington, in Devon- 

 shire; at Glanville's Wootton, in Dorsetshire; 

 in the Weald of Sussex, the Isle of Wight, 

 Birch and Darent Wood, in Kent; Essex, 

 Cambridgeshire; at Leominster, in Hereford- 

 shire, Worcestershire, and Yorkshire, but I 

 believe neither in Scotland nor Ireland. (The 

 scientific name is Tethea retusa.) 



607. The Angle -striped Sallow (Euperia fulvayo) . 



607. THE ANGLE-STRIPED SALLOW. The 

 palpi are very slightly porrected, the second 

 joint very stout, the terminal joint small and 

 pointed ; the antennse are very slightly ciliated 

 in the male, quite simple in the female : the 

 fore wings are scarcely arched, but decidedly 

 pointed at the tip; their colour is ochreous; 

 the discoidal spots and two transverse lines 

 being clearly but very delicately defined in 

 brown ; the median area of tho orbicular is 

 uniformly ochreous, that of the reniform has a 

 darker blotch at its lower extremity : the first of 

 the trans verse lines is bent or elbowed towards 

 the middle, it is considerably nearer the base 

 than the orbicular; the second is much bent, 

 but scarcely elbowed ; there is a very short 

 line going half-way across the wing at its 

 base; the lower part of the reniform is 

 occupied by a dark spot, and from this to the 

 middle of the inner margin is a slightly darker 

 shade : the hind wings are very pale ochreous : 

 the head and body are of the same colour as 

 the fore Avings, the body of the same colour as 

 the hind wings; the body of the female ter- 

 minates in a sharp-pointed ovipositor. 



Guenee has described the CATERPILLAR as 

 having the head fulvous-red, and the body 

 pale green or grayish, with a medio-dorsal and 

 sub-dorsal stripe white and continuous; there 

 is also a whitish lateral stripe in the region of 

 the spiracles ; the warty spots arc white also : 

 the CHRYSALIS is covered with'a violet-coloured 

 bloom : the caterpillar feeds on the oak 

 (Quercus Robur] and birch (Betula alba). 



The MOTH appears on the wing in August, 

 but is very local, having only been taken in 

 Derbyshire, Westmoreland, and Lancashire. 

 It occurs in Mr. Greene's List of the Lepi- 

 doptera of Ireland. (The scientific name is 

 Euperia falcac/o.}
