78 [September, 



spun under the leaves, that though of whitish colour it never showed 

 at all conspicuous, w^hile it served to veil the full depth of the larval 

 colouring ; indeed, the whereabouts of a larva could only be guessed, 

 by noticing pieces absent from the neighbouring leaves, as it was very 

 seldom I could detect one while it was stretched out a little beyond 

 its residence in the act of feeding. 



When full-fed they wandered restlessly for two or three days, 

 and then one spun itself up in a cocoon attached to the top of its cage 

 and to the leno cover, another spun its cocoon in a piece of hollow 

 stem provided for it, one in the leaves of marjoram, and the fourth I 

 accidentally squeezed, so that it was ujiable to spin and eventually 

 perished ; and I learned from Mr. Jeifrey that a similar untoward 

 mishap had befallen one of his only two larvae just when he had 

 brought them to maturity. 



From the larvae reared between us, three examples of the moth 

 were bred, the earliest by Mr. Jeffrey on 8th of last June, and two by 

 myself, probably somewhat later, as they had both died before I had 

 observed them. 



The egg of ancjuinaUs is round and flattened, becoming more and 

 more convex and plump above as the embryo develops ; the surface 

 is very finely pitted or reticulated, of a whity-greenish tint and 

 slightly glistening ; the day before hatching the darkish head of the 

 embryo shows through the shell. 



The newly-hatched larva is of a transparent flesh-colour, slightly 

 tinged with pinkish-grey, with a grey-brow'n head and neck plate, and 

 on the rest of the body most minute dusky dots and hairs ; it becomes 

 pinkish w'hen a week old, and very active. 



After the first moult it is semi-transparent tinged with dark pur- 

 plish-pink, which increases towards the end of this stage, and its 

 hammock is very transparent. 



After the second moult the larva is of a deep purplish brown-pink 

 colour, the skin less transparent than befoi'c, except the plate on the 

 second segment, which is translucent, glossy and gi'eenish, finely freckled 

 with black, the head similar but with browner freckles on the face ; the 

 spots on the body are very distinct, large, black, and glistening, while 

 the purplish-brown skin is dull and opaque ; ten days later, when seen 

 in repose it seems short and almost black, though when disturbed and 

 eager to escape it stretches itself out to S| mm., and is then seen to 

 be much more slender, and tapered at either end ; the colouring of the 

 head and second segment is as before a rather olive-green, but the skin 

 on other parts appears to be a very dark smoky-green, and slightly 

 clisteninsx at the serrniental divisions. A'y
