Descripiion of the Larva of Pseudopterpna cytisnria. — 

 The egg is laid on Genista anglica (dyei-'s-vveed) and Cyti- 

 sns scoparius (common broom), generally between the 20th 

 and 30th of July ; and the young larvce usually emerge in 

 fifteen days : they feed but sparingly, and are very small 

 when winter sets in : they may then be seen sticking on the 

 stems of the food-plants, perfectly rigid, and at an angle with 

 the twig of 45°: ihey appear perfectly indifferent to weather, 

 and even endure the severest frost without moving : in May 

 they feed up voraciously, and by the middle of Jmie are full- 

 fed ; they then rest in a very rigid but slightly bent position, 

 the head tightly tucked in, and the legs crowded together 

 and brought into immediate contact with the mouth. Head 

 narrower than the 2nd, and considerably narrower than the 

 following segments, deeply notched on the crown, which pro- 

 jects on either side of the notch into a conical but blunt point : 

 body after the 2nd segment of uniform substance, slightly 

 depressed, the sides slightly .dilated immediately below the 

 spiracles ; the anterior margin of the dorsal surface of the 

 2nd segment rises into two conical but blunt points, very 

 similar to those on the head, and having a similar inclination 

 forwards when the larva is at rest : the loth segment termi- 

 nates in two points directed backwards : entire siu-face of 

 head and body finely granulated or shagreened. Colour of 

 head and body didl opaque green ; the conical points on the 

 head tipped with pink : the conical points on the 2nd seg- 

 ment also pink ; dorsal surface with a narrow medio-dorsal 

 stripe a shade darker than the ground colour; at some dis- 

 stance on each side of this is an equally narrow stripe a shade 

 lighter than the ground colour; the lateral dilatation is white, 

 tinged throughout with pink and bordered below with red; 

 this dilatation, thus coloured, forms a most conspicuous late- 

 ral stripe, commencing immediately behind the head, ceasing 

 on the 4th segment, and, commencing again after the third 

 pair of legs, terminates on the 12th segment : spiracles very 

 pale : the ventral surface has three very distinct white stripes, 

 which converge without meeting between the third pair of 

 legs : legs and claspers concolorous with the body ; anal 

 points pink. My specimens, for which 1 am indebted to
