ENNYOHIA ANGtJlNALlS. 49 



colour it never showed at all conspicuous, while 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 neigh- 

 bouring leaves, as it was very seldom I could detect 

 one while it was stretched out a little beyond its resi- 

 dence 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 pro- 

 vided for it, one in the leaves of marjoram, and the 

 fourth I accidentally squeezed, so that it was unable 

 to spin, and eventually perished; audi learned from 

 Mr. Jeffrey that a similar untoward mishap had be- 

 fallen one of his only two larva3 just when he had 

 brought them to maturity. 



From the larvge reared between us, three examples 

 of the moth were bred, the earliest by Mr. Jeffrey on 

 the 8th of June, 1882, and two by myself, probably 

 somewhat later, as they had both died before I had 

 observed them. 



The egg of Ennychia anguinalis is round and flat- 

 tened, 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- 

 brown head and neck-plate, and on the rest of the 

 body most minute dusky dots and hairs ; it becomes 

 pinkish when a week old, and very active. 



After the first moult it is semi-transparent, tinged 

 with dark purplish-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 pur- 

 plish brown-pink colour, the skin less transparent 

 than before, except the plate on the second segment,
