BRITISH MOTHS. 



191. The Small Blood -vein (Acidalia imitaria). 



191. THE SM AL L BLOOD-VEIN. The antennae 

 of the male are very slightly fringed ; of the 

 female quite simple ; the fore wings are pointed, 

 the hind wings sharply angled ; all the wings 

 clay-coloured, with a broad oblique brown band 

 continued across both the fore and hind wings; 

 this band passes outside a central brown dot 

 on the fore wings, and inside a central brown 

 dot on the hind wings ; between this oblique 

 band and the hind margin, there is a delicate 

 transverse waved line of the same colour, and 

 a similar line, as regards delicacy and colour, 

 on the hind margin itself, and just within the 

 fringe. 



The Rev. H. Burney has found the CATER- 

 PILLAR of this moth on broom ; it is very long 

 and very slender, quite threadlike, with white 

 marks down the back : he found, however, 

 that it would not eat broom, and at last fed it 

 on sorrel (Rumex acetosella) : it spun up at the 

 end of June, and turned to a yellowish-brown 

 CHRYSALIS. 



The MOTH came out on the 14th of August : 

 it is not uncommon in the south of England, 

 and occurs occasionally as far north as York, 

 and in two Irish counties, Cork and Kerry, 

 but has not been found in Scotland. (The 

 scientific name is Acidalia imitaria.) 



192. The Rosy Wave (Acidalia emutaria). 



192. THE ROSY WAVE The antennae are 

 almost simple in both sexes ; all the wings are 

 yellowish-white, with a delicate rosy tinge of 

 mother-of-pearl, and each having an obscure 

 central dot ; there is an oblique line from the 

 tip of the fore wing to the middle of its -inner 

 margin ; and a second equally faintand obscure 

 line halfway between this and the base ; be- 

 sides these there are three very oblique series 



of small dark spots on the fore wings, and two 

 on the hind wings. The first of these series 

 on the fore wings is generally composed of 

 three spots, the second of eeven or eight spots, 

 and the third, also composed of seven or eight 

 spots, is on the hind margin, and in very fine 

 and fresh specimens these marginal spots are 

 connected together by an extremely delicate 

 line; on the hind wings the first series of 

 spots is generally composed of eight spots, and 

 crosses the middle of the wing in a straight 

 line ; on the margin itself is a double series of 

 elongated markings, connected by a threadlike 

 line ; the face is dark brown, the collar paler 

 brown, the crown of the head, thorax, and 

 body delicate whitish-gray. 



The MOTH appears about the middle of 

 summer, and is found in the Isle of Dogs and 

 at Woolwich, close to the banks of the 

 Thames. (The scientific name is Acidalia 

 emutaria.) 



193. The Eiband Wave (Acidalia aversata ; 

 variety, remutata). 



193. THE RIBAND WAVE. The antennae 

 of the male are very slightly pubescent, those 

 of the female quite simple. All the wings 

 are of a pale dingy yellowish-gray, the fore 

 wings having three transverse lines and the 

 hind wings two; just inside the second of 

 these lines on the fore wings is a central very 

 small brown spot ; on the hind wings is a 

 similar spot, generally situated on the first 

 transverse line, but this situation is not con- 

 stant ; it is sometimes inside and sometimes 

 outside of the first line ; the entire space be- 

 tween the second and third lines on the fore 

 wings, and between the first and second lines
