BRITISH MOTHS. 



latter includes a distinct but very small round 

 discoidal spot ; about the middle of the mar- 

 ginal bind is a snow-white lunule ; with tlic 

 exception of the pale median band, every part 

 of the wing is traversed by slender dark brown 

 transverse lines: the hind wings are gray, 

 tinged with brown, and have a small discoidal 

 spot, slender waved transverse lines across the 

 middle, and a broad marginal band rather 

 darker, and intersected by a sinuous pale line ; 

 the margin itself is very distinctly scalloped 

 and dark brown ; the head and thorax are 

 rich umber-brown, the body pale brown at 

 the base, rather darker at the tip ; there are 

 two daik spots placed transversely on each 

 segment. 



The EGGS are laid in March, on the buds or 

 stems of the dog-rose (Rosa canina). 



The CATERPILLAR is full-fed at the end of 

 May, when it rests in a nearly straight posi- 

 tion, attached by the claspers only. The head 

 is semi-porrect, slightly notched on the crown, 

 slightly narrower than the body : the body is 

 of uniform size throughout, slightly depressed, 

 and entirely without humps. At first, all the 

 caterpillars are green, afterwards they vary 

 slightly: the colour of the head is orange, 

 with a large black spot on each side just above 

 the ocelli ; the dorsal area of the body is 

 green, sometimes exquisitely shaded, more 

 especially towards the sides, with purple ; the 

 second segment has a slender medio-dorsal 

 pale line, on each side of which are four 

 white dots arranged in a square, and below 

 these on each side are two other white dots 

 placed transversely ; the third and fourth seg- 

 ments have each a transverse series of six 

 white spots on the back, and two placed 

 longitudinally on each side ; the fifth, sixth, 

 seventh, eighth, ninth, tenth, eleventh, and 

 twelfth segments have each four dorsal white 

 dots arranged nearly in a square ; the thir- 

 teenth segment has a transverse series of six 

 similar dots, and every segment has a lateral 

 white dot at the junction of the dorsal and 

 ventral area ; the anal flap is rounded, and 

 dark purple-brown; the sides of the second, 

 third, and fourth segments are reddish brown ; 

 the sides and ventral surface of the other 



segments are dingy white ; the spiracles in- 

 tensely black; the legs green; the ventral 

 claspers pale green, with an intensely dark 

 purple brown blotch on the outside; the anal 

 claspers are dingy, with a similar blotch. It 

 lei'ds on the leaves of the dog-rose, and 

 descends to the ground and changes to a 

 CHRYSALIS on the surface of the earth in an 

 earthen cocoon. 



The MOTH appears on the wing in April, 

 and is of frequent occurrence in some of our 

 English counties, and Mr. Eirchall says it is 

 very common in Ireland. (The scientific 

 name is Ant idea badiata.) 



331. The Streamer (Anticlea derivata}. 



331. THE STREAMER. The fore wings are 

 purple-brown, with a paler median area, and 

 having a delicate gloss over the whole surface ; 

 they have two darker bars, the first near the 

 base, short, narrow, a,nd rather obscure, the 

 second before the middle of the wing, and 

 very strongly pronounced ; beyond the middle 

 of the wing is a dark brown blotch on the 

 costa, the two margins of which are continued 

 as mere lines to the inner margin ; the inner 

 of these lines is simply scalloped, the outer is 

 much angled, the angle projecting almost to 

 the middle of the inner margin ; midway 

 between the second bar and the first of these 

 lines is a small but distinct dot-like discoidal 

 spot ; the hind wings are gray, with a purple- 

 brown gloss, but with scarcely any markings; 

 the head, thorax, and body have various shades 

 of brown, the margins of the segments being 

 pale. 



The EGGS are laid in March or April, on 

 the buds or stems of the dog-rose (Rosa canina*), 

 on the leaves of which species the caterpillar 

 feeds ; the CATERPILLARS are full-fed in ^Fay, 

 when they rest in a straight or but slightly
