BRITISH MOTHS. 



373. The Manchester Treble-bar (Carsia imbutata). 



373. THE MANCHESTER TREBLE-BAB. 

 The palpi are very scaly, porrected, and the 

 points slightly deflected in the form of a 

 hooked beak ; the antennae of the male are 

 pubescent ; the fore wings are slightly 

 pointed, and their costa is perfectly straight; 

 their colour is ashy-gray with a short 

 oblique brown line near the base, and a 

 broad median band of an umber-brown 

 colour, and doubly angulated on its outer 

 margin ; this band opens at both extremi- 

 ties, and includes a gray space at each end ; 

 sometimes the gray spaces unite and form 

 a pale band within the dark one ; both 

 margins of the median band are slenderly 

 bordered with white ; the broad hind-mar- 

 ginal area is clouded with purple-brown, 

 and surrounding each of the two principal 

 angles of the median band is a suffused 

 blotch of a brick dust-red colour ; the hind 

 wings are gray -brown: the head, thorax, 

 and body are cinereous gray. 



The CATERPILLAR feeds on the cranberry 

 (Vaccinium oxycoccos) ; I have never seen 

 it. Freyer describes it as " reddish yellow, 

 with three wide stripes down the back; 

 spiracular line yellowish white." Stainton's 

 Manual., vol. ii. p. 120. 



The MOTH appears on the wing in July, 

 and is very local. I have it from the 

 neighbourhood of Manchester, where it 

 appears abundant ; it has been received from 

 Scotland, and Mr. Birchall has taken it at 



Howth, in Ireland. (The scientific name IB 

 Carsia imbutata.) 



374. The Treble-bar (Anaitis plagiata). 



374. THE TREBLE-BAR. The antennae 

 are simple in both sexes ; the fore wings 

 are ample and rather pointed at the tips ; 

 they are of a distinct dove-colour, and 

 traversed by transverse markings, the first 

 of which is near the base, and is sharply 

 bent as it crosses the sub-costal ray ; it is 

 rathw broad at the costal margin, very 

 narrow and linear at the inner margin, it 

 opens at the flexure and contains a small 

 dove-coloured space ; the second marking 

 is rather before the middle of the wing, 

 and may be called a triple bar ; it is single 

 at the costal, and triple at the inner margin ; 

 the third may also be called a triple bar ; 

 it has two sharp angles on the outer side ; 

 as it approaches the inner margin it bends 

 slightly towards the anal angle of the wing ; 

 just on the costal margin the three lines 

 forming this bar are united : there is a 

 short longitudinal black streak at the base 

 of the wing, four faint transverse lines 

 between the first and second of the principal 

 markings (two of them very imperfect), a 

 faint linear discoidal spot between the 

 second and third (triple) bars, three faint 

 lines between the third (triple) bar and the 

 hind margin, and finally, a short oblique 

 black streak running from the tip of the 

 wing, and terminating in a little rust- 

 coloured cloud before it reaches the upper 

 angle of the triple bar : the hind wings are 

 smoky-gray, with a double median trans-
