by Mr. Bristow in the county Wicklow. 

 (The scientific name is Phibalaptert/x lignata.~] 



t3. The Many-lined (Phibalapteryx covjunctaria}. 



343. THE .MANY-LISTED. The antennae ap- 

 pear slightly thicker in the male ; the fore 

 wings are very pale wainscot-brown, with 

 numerous transverse darker lines ; two of 

 these, near the middle of the wing, enclose an 

 area which is darker round the margins, and 

 especially near the inner margin, and paler in 

 the middle ; the pale part including a small 

 but very distinct discoidal spot ; exterior to 

 this median enclosure, a very oblique dark 

 band crosses the wing from the extreme tip to 

 the inner margin, and the costa itself is of the 

 same colour, but interrupted by five or six 

 pale spots ; in addition to these principal 

 markings there are several transverse dark 

 lines : the hind wings are pale wainscot-brown, 

 with six or seven transverse darker lines which 

 originate on the inner margin, and terminate 

 ther beyond the middle of the wing : the 

 thorax, and body are pale wainscot- 

 wn, the body having two black spots placed 

 transversely on each segment. 



'he MOTH appears twice in the year, in 

 ch and September ; it has been taken in 

 damp meadows near Bristol and Cambridge, 

 but is extremely local. I am not aware 

 of its having been taken in the north of 

 England, in Scotland, or in Ireland. (The 

 scientific name is Phibalapteryx conjunctaria.} 

 Obs. This moth is the Phibalapteryx poly- 

 graniinata of Doubleday's List, and Mr. 

 Doubleday himself informs me that it is 

 certainly the Phibalapteryx conjunctaria of 

 Lederer, who has sent him a specimen of the 

 true Phibalapteryx polygrammata of Borkhau- 

 sen, which is very different in general appear- 

 ance from our English insect described above. 

 Guenee appears to think that the two insects 

 are not specifically distinct, and makes con- 



tran 

 Mar 



junctaria a variety of polygrammata, a view of 

 the case which Mr. Doubleday adopted in his 

 Catalogue of 1866. 



344. The Small Waved Umber (Phibalapteryx 

 vitalbata}. 



344. THE SMALL WAVED UMBEK. The 

 antenna) are almost simple in the male, but 

 appear somewhat stouter than those of the 

 female ; the fore wings are long and rather 

 pointed, of a pale wainscot-brown colour, with 

 a broad oblique smoke-coloured shade, which, 

 commencing below the tip of the wing, ter- 

 minates near the middle of its inner margin, 

 and includes several waved umber-brown 

 lines : there is a small but very black discoidal 

 spot, and between the oblique shade and the 

 hind margin are two waved umber-brown 

 iines : the hind wings are dingy grayish- 

 brown, with numerous waved transverse 

 darker lines : the head is dark brown ; the 

 thorax pale, with two transverse dark brown 

 belts ; the body dark brown, with paler belts. 



The EGGS are laid during the summer months, 

 July and August, on the common honesty or 

 traveller's joy (Clematis vitalba), and the 

 CATERPILLAR feeds, as far as my observations 

 extend, exclusively on this plant. 



It appears to be full-fed in October, and 

 then rests in a very rigid, straight, and stick- 

 like position, attached by its claspers, and 

 sometimes also by its feet, often thus forming 

 a bridge between two leaves or petioles ; the 

 head is equal in width to the second segment, 

 flat, generally porrected on the same plane as 

 the body, but when the caterpillar is annoyed, 

 it is bent down into a prone position ; the 

 antennal papillae are very conspicuous and 

 slightly divergent: the body is cylindrical, 

 but has a lateral skinfold, and is wrinkled 

 transversely, the wrinkles being more mani- 

 fest towards either extremity ; the head and 

 body have many small scattered warts, and
