of which it occurs in the utmost profusion. It is generally sup- 

 posed that there are tvA^o broods in the year, one in May, the 

 other in August ; but from the observations of my deceased friend, 

 E. Blunt, Esq., I presume that supposition is inaccurate, as he 

 informed me that he had taken the larvae in all its stages at one 

 time, and that the perfect insect continued to make its appearance 

 with regularity from tlie end of May to the middle of August ; but 

 as these larvae were taken at large, and in various places, it is pro- 

 bable that some fortuitous circumstances might have caused the 

 appearance of some of them to be procrastinated. The perfect 

 insect flies with rapidity, and is difficult to catch, unless in perfectly 

 calm weather : it has sometimes been captured close to London, in 

 Epping Forest, at Stepney, and near Peckham ; and it was for- 

 merly abundant at Westerham, in Kent. Mr. Dale has frequently 

 taken it at Glanville's Wooton, and in other parts of Dorsetshire : 

 it also occurs as far north as Beverley, in Yorkshire, and west as 

 Redlane, near Bristol, in Somersetshire. 



Genus II. — Gonepteryx, Leach. 



Antennw short, stout, very gradually thickening into an obconic club : palpi short, 

 much compressed, the terminal joint very short : wings angulated, large, the 

 posterior grooved to receive the abdomen : legs alike in both sexes, short, 

 stout; claws minute, bifid. Caterpillar naked. Chrysalis angulated, acu- 

 minated in front : fastened with a loose thread round its middle.

 This insect appears to have been introduced into the British Fauna upon the 

 most loose and unsatisfactory authority. Its introduction by modern authors 

 arose from the following words of the celebrated Ray : " Prope Libernam, 

 portum in Etruria, invenimus, at etiam, ni male memini, in Anglia." — Rai/. 

 Ins. p. Ill : and from the expression of Berkenhout, who says, in his 

 Outlines, that it is " rare in woods." Now, as the attention of entomologists 

 has been so especially drawn towards the solution of this point for at least forty 

 years, and no authentic instance of its capture is recorded, it seems absurd 

 to consider it any longer as a British species ; but, notwithstanding, there are 

 several entomologists sanguine enough to expect that it may eventually occur 

 in some of the unexplored parts of the country; although its highest northern 

 range on the Continent appears to be about the latitude of Paris.
