The egg i? globular, with base rather flattoiied ; the shell ribbed ratlier irregularly 

 with about eighteen ribs, and transversely recticulatod with very even fine lines, 

 which do not stop at the ribs, but cross them, giving their edges a rough appearance 

 which is not real, but only caused by the ribs, otherwise translucent, becoming opaque 

 where the lines cross ; as usual, a small space on the top of the egg is covered only 

 with very fine concentric reticulation ; the colour is a very pale green all over. 



The young larva makes its escape by cutting a large round hole through the top 

 of the egg ; in colour it is very pale green, with head and collar shining black ; every 

 tubercular dot bears a pale bristle, longish and straight on the head and thirteenth 

 segment, but on the other segments bifid, with the tips curved on either side like an 

 unbarbed double fish-hook. When about one-sixth of an inch long, the colour is pale 

 puqjlish-pink, the head still black ; when nearly half-au-inch long it is pale green 

 again, the whole skin now thickly set with short straight hairs ; the bifid bristles 

 having been parted with, I imagine, at the first moult. "VVheu full-grown, the length 

 is rather over five-eighths of an inch, the figure very stout, the head horny, globular, 

 and stuck like a knob on the second segment, which, however, is not so strikingly 

 narrow as in Thanaos Tages ; the skin granulated in appearance ; the head and whole 

 body covered thickly with short fine pale hairs ; the general colour a pale ochreous- 

 green, the second segment pinkish, and a faint reddish tinge over the back of the 

 other front segments ; a thin dorsal, and somewhat broader sub-dorsal line, not 

 easy to be seen, of ground colour, and a faint spiracular line : the spiracles not 

 much darker than the ground colour ringed with the same tint as the lines ; the 

 belly freckly ; the head and collar very dark purplish-brown, the upper lip paler. 



The pupa is enclosed in a cave between two or three leaves, similar to that in 

 which the larva lives, but fastened with stouter silk, and the openings protected by 

 a loose pale yellow webbing ; its length is not quite half-an-inch, the figure thick and 

 stumpy ; the eyes prominent, the wing-cases well developed ; the whole skin rather 

 rough ; the middle of the head, the eyes, and the back set with short stiff hairs : 

 the ground colour reddish-grey, the wing-cases pinkish-grey; the abdomen tinged with 

 brownish-red along the back ; on the centre of the head, on the eyes, and on either 

 side of the thorax above the wing-cases, are some blackish-brown marks ; there are 

 smaller marks in pairs down the middle of the thorax, and there arc transverse rows 

 of spots on the segments of the abdomen, the largest and darkest being next the 

 wing-cases; the hairs are light brownish-red ; the anterior spiracle black, the others of 

 the grey ground colour, ringed with black, and placed within the largest dark blotches.

Occurrence of Myelois cirrigerella, Zk., a species tieiv to BrUain. — Specimens 

 of this interesting little addition to our list of Phycidic were submitted io Mr. 

 Barrett, who kindly forwarded them to Prof. Zellcr for determination ; and he has now 

 returned them with the above name. They were taken June 30th, 1S71, at light in 

 the neighbourhood of Marlborough, Wilts ; some eiglit or nine specimens came in 

 the course of the evening, but I only secured four in a condition worth setting, as 

 they manifested a most pernicious affection for the flame of my candles ; the remain- 

 der succeeding in self-immolation. I did not meet with more on subsequent evenings, 

 which I attribute principally to somewliat unfavournblo weather. Some of the
