spinning together the edges of some of the leaves, and con- 

 structing a kind of imperfect tent, in which they are con- 

 cealed from birds. The larva is full-grown at the beginning of 

 June ; it then rests in a tolerably straight position, and if dis- 

 turbed falls from its food-plant, curled up into a very lax and 

 imperfect ring, and remains motionless for many minutes. 

 Head rather small, decidedly narrower than the body, por- 

 rected in crawling : body smooth and velvety, almost uni- 

 formly cylindrical, but evidently attenuated towards both 

 extremities, and having the ventral flatter than the dorsal 

 surface. Colony; of the head almost white, having an ex- 

 tremely slight tint of green, and being' finely reticulated on 

 the cheeks with a darker colour ; it also has black mandibles, 

 a straight black transverse line just above the mandibles and 

 labrum, and a black margin where received into the 2nd seg- 

 ment ; this black margin is only observable when the larva is 

 crawling. Body pale glaucous-green, with five still paler 

 but scarcely white equidistant dorsal stripes; the broadest of 

 these is raedio-dorsal, and, together with the next on each 

 side, extends from the head to the extremity of the anal flap ; 

 the exterior stripe on each side passes just below the 

 spiracles, touching all of them, except the 9th ; the spiracles 

 are perfectly white, encircled with a black ring ; between the 

 medio-dorsal and the next stripe is a series of about thirty 

 small circular spots, or rather dots, of exactly the same 

 colour ; there are three on each segment, the middle one 

 being nearest the medio-dorsal stripe ; each has a minute 

 black dot in the centre, and from the black dot emanates a 

 very slender bristle : the ventral surface and claspers are con- 

 colorous with the back ; the legs paler and almost transparent, 

 and encircling the base of each is a black ring, which emits 

 two spreading branches anteriorly. I am indebted to Mr. 

 Doubleday for a supply of these larvae, which were full-fed 

 the first week in June, when they spun up in leaves that had 

 fallen on the earth at the bottom of the breeding-cage. The 

 moth occurs amongst the foliage of the oak throughout Au- 

 gust and September, and frequently falls into the umbrella 

 when the Entomologist is bearing for autumnal larvae. —
