lens, two rows of most minute brown dots can just be discerned on 

 the back ; the narrow silken somewhat tubular hammock is extremely- 

 thin and of pale brownish colour, w^herein the occupant lies curled up 

 motionless, and might be very easily overlooked without arresting 

 notice as a larva. 



After the second moult it is grown but little, and seems very 

 much as before, except that the skin of the body generally is more 

 opaque, and bears a faint tinge of bluish-green above and a paler tint 

 of greenish-drab below, the dark red head is followed by the darker 

 brownish red plate, and a very small dark plate appears on the anal 

 flap, the brown tubercvilar dots are more noticeable ; it seems always 

 at rest in a close coil, either at one end or in the middle of its long 

 transparent brownish web, and if turned out of its abode to examine 

 is very timid, seldom uncoils, and for a long time is afraid to move ; 

 though not detected either by Mr. Jeffrey or myself in the act of 

 feeding, yet, that it feeds well, probably at night, is shown by portions 

 eaten out from leaves of hazel and Lotus major, and also, as Mr. 

 Jeffrey advised me, from tender leaves of Agrimonia eupatoria, sallow, 

 and hornbeam. 



After the third moult the skin is quite opaque and of a dark 

 chocolate-brown colour above, a very dingy pinkish beneath, the head 

 rather widest in front near the mouth and a trifle flattened, is of 

 brownish-red colour, the plate on the second segment is broad, black- 

 ish-brown, and for a time appears dorsally divided, the small anal 

 plate is of the same dark colour, the tubercular dots are rough, 

 blackish, and ranged on either side of the back longitudinally in a 

 straiglit line loitli each other, each dot bearing a fine hair ; a most 

 remarkable addition occurs a little below these on either side nearly 

 close to the beginning of each segment beyond the thoracic, in that 

 of a small ocellated crater-shaped spot with dark brown centre bearing 

 a hair, other rough dark dull dots, similar to those on the back, occupy 

 the usual tubercular situations along the sides and ventral region, the 

 fifth and sixth segments on the belly have a transverse series of these 

 close together : the grey -brown web it spins for its dwelling amongst 

 the leaves now arrests attention from its curious construction, as when 

 seen while the twigs are in an upright position, the web is partitioned 

 off into several cells or chambers, one above the other, by delicate 

 diaphragms or floors, so to speak, varying in number, but often as 

 many as from three to five, openly wrought and with fine connecting 

 ' threads, the larva occupying sometimes one chamber sometimes another, 

 almost always in its characteristic posture with the tail curled round
