SERICORID.E—RETINIA. 35, 



beyond the middle a broader similar line or stripe, more 

 broadly forked toward the dorsal margin ; between is a dis- 

 tinct white costal dot, and beyond a fine erect submarginal 

 line — the bright ground colour and the shining white lines 

 are all distinct and well marked to the extreme dorsal margin 

 — cilia silvery- white. Hind wings pale smoky brown with 

 white cilia. Female larger, and having the hinder silvery- 

 white stripe more distinct, otherwise similar. 



Underside of the fore wings dark smoke-colour ; costal 

 spots and cilia white. Hind wings smoky white. 



On the wing in July and August. 



Larva appareutlj- undescribed ; in the shoots of Scotch 

 fir {Pinus ST/lvestris) — said to jorefer a leading shoot — and 

 also in spruce fir (P. ahics). 



The moth is not of so lively a disposition as the last species, 

 and if disturbed in its haunt in a fir-tree by day will fall to 

 the ground rather than fly ; its natural flight towards dusk is 

 straighter and more sedate, though it then flies over the trees 

 and high branches. Fourd with us throughout the Southern 

 Counties of England from Kent to Somerset, and the Eastern 

 to Norfolk ; also in Berks, Herts, Herefordshire, Cheshire, 

 Lancashire, and Yorkshire ; but I have no record of its more 

 extensive distribution in these Islands, and abroad it seems 

 to have been usually confounded with the last species.
