New British Species for 1863. 



Procris Geryon^ Hiibner. The uncertainty as to the 

 specific distinctness of our smaller PrQ£ris from P. Statices 

 has at length been satisfactorily cleared up by the discovery 

 of its larva through the energy of the Rev. E. Horton. The 

 larva which Mr. H. Doubleday says (Zool. 8732) can be 

 , easily separated from that of Statices, was found feeding on 

 the Heliarithemum vulgare in May. A very excellent de- 

 scription of the larva is given by Mr. Newman (Zool. 8696). 

 Some remarks on this species translated from the German of 

 Dr. Staudinger (Zool. 8403) are also exceedingly interesting. 

 The perfect insect is distinguishable from that of P. Statices 

 by its greater stoutness, its abdomen and thorax being pro- 

 portionately much larger, and the antennae shorter, stouter, 

 of morp uniform thickness, and blunter at the distal ends. 

 In England the insect has occurred near Brighton, Durham, 

 Beverley, Worcester, Canterbury, York, and Manchester. 

 Its habit is to fly in the daytime, though more swiftly than 

 Statices, soon settling again. It frequents downs : the date 

 of appearance of the perfect insect is June. 



Leucaiiia Loreyi, Duponchel. On the 14th October, 

 1862, Mr. Thorncroft captured two females of this species in 

 rather wasted condition, whilst sugaring at a locality a few 

 miles from Brighton (Zool. 8407). This species is not very 

 closely allied to any of our known Leucanidce ; its ordinal 

 position appears to be between L. Ohsoleta and L. Littoralis, 

 possessing in slight degree some of the characters of both, 

 but while the ground colour of the forewings (somewhat 

 like that of Littoralis), and the white hind wings, at once 

 separate it from the former, it is with equal ease distinguished 

 from the latter by the absence of the conspicuously white
