198 EUDORKA ANGUSTEA. 



tolerably satisfied that only one brood occurred at 

 Worthing, as he could scarcely have missed an early 

 brood had it been present on the spot where he found 

 his larvse. The first ima^o from these larvse did not 

 appear until the 10th of October, and the last on the 

 27th ! It certainly is most odd that with only one 

 brood in the year it should be well on the wing in our 

 northern county before the end of July, and not 

 appear on the south coast until October. The species 

 is generally supposed to hibernate as imago, but 

 whether it does so here I am unable to say. Some of 

 my captured females deposited bright straw-coloured 

 eggs, but it is quite possible that, had they been 

 unmolested, they might have retained them until 

 spring. 



Length of larva, half to five-eighths of an inch, and, 

 for a Scoparia, rather slender. Body cylindrical and 

 of nearly uniform width, tapering very slightly at the 

 anal extremity; head about the same width as the 

 second segment, and is, as is also the frontal plate, 

 highly polished ; the skin and the large tubercles 

 smooth and glossy; the segmental divisions deeply 

 cut. 



Ground colour very dark smoky-grey, with an 

 indistinct greenish tinge; head pale brown, the man- 

 dibles darker brown ; frontal plate very dark sienna- 

 brown, in some specimens as nearly black as possible ; 

 tubercles of a darker shade of the ground colour, in 

 some, like the frontal plate, being nearly black. 



The ventral surface is of a rather paler shade of 

 the ground of the dorsal area, the legs ringed and 

 tipped with black. 



Feeds in silken galleries on one of the common 

 wall-mosses. 



The pupa is about three-eighths of an inch long; 

 bright pale yellow, the eye-cases, abdominal divisions, 

 and anal tip brown. (George T. Porritt, 7th January, 

 1886; E.M.M., February, 1887, XXII, 209.)
