Descripiioii of the Larva of Polyommaiiis Hippoihoe 

 (Large Copper). — The egg is laid on the leaves of Ruraex 

 hydrolapathum (great water-dock), during the month of Au- 

 gust, and the young larvae (never, to the best of my belief, 

 observed) probably emerge during the following month, and 

 hybernate very early at the base of the petioles, a situation 

 in which they would be particularly liable to injury, and 

 indeed destruction, from the long-continued floods of such 

 frequent occurrence in the aqueous districts, which consti- 

 tuted the sole English habitats of this brilliant butterfly. 

 The larva is full-fed in June, and then lies flat on the dock- 

 leaf, rarely moving from place to place, and, when it does so, 

 gliding with a slug-like motion, the legs and claspers being 

 entirely concealed. Head extremely small, completely with- 

 drawn into the •2nd segment; body with the dorsal surface 

 convex, the ventral surface flat; the divisions of the seg- 

 ments are distiiictly marked, the posterior margin of each 

 slightly overlapping the anterior margin of the next, and the 

 entire larva having very much the appearance of a Chiton ; 

 the sides are slightly dilated; the legs and claspers are seated 

 in closely appi'oximate pairs, nearly on a medio-ventral line. 

 Colour green, scarcely distinguishable from that of the dock- 

 leaf; there is an obscure medio-dorsal stripe, slightly darker 

 than the disk, and in all probability due to the presence of 

 food in the alimentary canal. Pupa obese, blunt at both 

 extremity, attached by minute cremastrae at the caudal ex- 

 tremities, and also by a surcingle round the waist : the exact 

 duration of the larval and pupal states not observed ; the 

 butterfly appears on the wing in August. Formerly abun- 

 dant at Whittlesea Mere, in Cambridgeshire, and Yaxley 

 Fen, in Huntingdonshire, but not observed for many years, 

 and now generally supposed to be extinct in Britain. My 

 acquaintance with the larva and pupa was made very many 

 years ago, in Mr. Doubleday's garden at Epping, where the 

 very plant of Rumex hydrolapathum on which the larvae fed 

 is still in existence. — Id.
