JUNIPER CARPET. 177 



The hind wings are whitish, tinged more or less with greyish or 

 pale brownish, but always paler than in any form of T. variata, 

 with which it is often confused. (Plate ^o^ Figs. lo, ii.) 



The caterpillar is bluish-green above, and green beneath ; 

 three lines along the back, the central one a darker tone of the 

 ground colour, the others whitish ; head reddish, marked with 

 brown on each cheek. It feeds in April and May (June in 

 Scotland) on Scots pine ; Barrett states that there is a second 

 brood in August. (Plate 71, Fig. 2.) 



The moth is out in September and October, and may be 

 disturbed from the pine boughs, or occasionally seen resting on 

 the trunks, but it is more frequently met with at night when it 

 flies naturally, and has been known to visit the sugar patch. 

 Barrett, who considered this species to be double brooded, 

 gives June and July for the first flight of moths. Certain it is 

 that moths have been reared even as late as October from 

 Spring caterpillars. As adverted to, the pale reddish forms of 

 T. variata are sometimes confused with T. firmata^ but in 

 addition to other differences indicated above, it may be noted 

 that in the male of the latter the antennae are bipectinated 

 except towards the tips. Most rf the pine woods throughout 

 England seem to produce this delicate insect more or less fre- 

 quently ; the same remark applies to Wales. In Scotland it is 

 found up to Aberdeen, and also in the Hebrides. The only 

 localities mentioned by Kane for Ireland are in counties 

 Wcitmeath, Dublin, and Fermanagh.

On Plate 70, Figs. 4 and 5 represent the sexes of the typical 

 form of this species , the small and rather moie strongly marked 

 Scottish form is shown by Figs. 7 and 8. In the^e snail foims 

 a notice ible character is the bro^vnish band on the fore wings, 

 between the central band and the outer margin ; this band is
