leaf on which the larva is standing : when handled or disturbed it does not feign 

 death or fall off its food, but remains motionless, clinging with great tenacity to the 

 leaf; in this operation it uses the ventral claspers only, the legs not touching the leaf, 

 and the caudal extremity being elevated. Head prone, with a bilid crown, its divi- 

 Sii/ns conspicuous, but obtuse : 2nd segment with four minute pointed warls, trans- 

 versely aiTanged ; 3rd segment with two larger dorsal warls, placed transversely ; 4th 

 segment with two still larger dorsal warts, also placed transversely ; 1 Ith segment with 

 a transverse dorsal protuberance ; r2th segment with a pair of minute dorsal warts, 

 placed transversely: every wart terminates in a minute bristle: ventral claspers eight, 

 on the usual segments ; caudal claspers aborted, or soldered together and forming a 

 single terminal and gradually attenuated spine or spike, which never appears to touch 

 the leaf on which the larva is feeding, but to be elevated in the air without occupa- 

 tion; at the base of this spike is a minute wart on each side : the body is altogether 

 rugose, and the skin pitted with small depressions. The colour is dingy brown, with 

 a narrow median darker dorsal stripe, and numerous minute rivulet markings, and also 

 a pale lateral elevated line on each side of the 12th segment. Feeds on Crataegus 

 Oxyacantha (whitethorn), and is full fed the first week in July. When full fed it 

 spins a tough gummy cocoon, attaching it to a twig of the hawthorn, generally in the 

 axil of one of the thorns, and fixing, on the exterior, fragments of the still green leaves 

 in such a manner as to conceal the cocoon effectually from sight; in this the pupa 

 remains not longer than two or three weeks : the moth appears ou the wing towards 

 the end of July. — Edward Neivman, 



Description of the Larva of Clostera anachoreta. — Does not roll in a ring, fall, or 

 feign death when disturbed; body slightly depressed, having a double skin-fold, ex- 

 tending its entire length, on each side in the region of the spiracles, a prominent 

 median hump on the back of the 5th segment, and a second but less prominent me- 

 dian hump on the back of the 12th segment. Head black, slightly shining, beset with 

 chestnut hairs : body velvety black, mottled and reticulated with smoky gray ; a broad 

 median stripe of dingy while down the back ; this stripe is composed of square median 

 markings, which are situated respectively on the 4ih, 6th, 7th, 8th, 9ih, 10th and 1 1th 

 segments ; that on the 4th segment is isolated, but not so clearly defined as the others, 

 which are strung together by four parallel whitish lines, situated in the interstices of 

 the segments ; these connecting lines are especially observable when the larva is 

 crawling: the humps on the 5th and I2th segments are bright chestnut-brown ; that 

 on the 5th emits a few longish chestnut-brown hairs ; and there are a series of 

 markings of a similar colour along each side on the elevations of the skin-folds, both 

 above and below the spiracles : the 5th segment is entirely without the median white 

 mark, its site being occupied by the chestnut-brown hump, and on each side of this is 

 a somewhat square spot of snowy whiteness, and entirely surrounded with intense vel- 

 vety black : on each side of each of the square white dorsal markings is also a squarish 

 spot of intense velvety black : the back of the 2nd, 3rd and 13th segments have a 

 transverse series of small chestnut-coloured prominences, emitting chestnut-coloured 

 hairs ; the belly is pale smoky gray; the legs black ; the claspers smoky flesh-coloured. 

 This beautiful larva was first found by my friend Mr. Sidney Coop&r, feeding as he 

 believes on Salix capraa (sallow) ; afterwards by Dr. Knaggs, feeding on Populus 

 nigra (black poplar) : Mr. Cooper only took two specimens, not being aware of the 

 value of his capture until the perfect insect emerged : Dr. Knaggs was more fortu- 

 nate, and, although he obtained bnt a few individuals, has succeeded in maintaining
