past season, and several descriptions having been penned by 

 both Continental and British authors. These descriptions, 

 so far, agree pretty closely in the main points; but then none 

 of them, I believe, have reference to the larva of Typhon. 



Annon Sesia philanthiformis, Laspeyres? 



The depths of the synonymy of the little clearwing, which 

 in 1860 was added to our lists, as an inhabitant of our 

 West coast, and for which the specific names of 'philanthi- 

 formis, Lasp., and muscceformisj Bork., have been respec- 

 tively suggested, have not as yet, it would seem, been 

 thoroughly fathomed. 



Respecting philanthiformis and its allies, even Conti- 

 nental authors themselves do not appear very clear. For 

 instance, according to Dr. Staudinger's Catalogue: — 



Musccpformis, Hufn. = Philanthiformis, Lasp. v 



Muscaformis, Bork. = Empiformis, Esper. / All the latter 



Mvscaiformis, H.-S, = Annellata, Zell. I (according to 



Philanthiformis, Ramb. ? = Corsica, Stdgr. [ Staudinger) be- 



Philanthiformis, Led. = Braconiformis, H.-S. j ing good species. 

 Philanthiformis, H.-S. = Bibioniformis, Esper. 



So that thus, without going further into the subject, the 

 reader will find that the two names pliilanthformis and 

 miiscceformis have stood for no less than six distinct species, 

 not one of which, at the present moment, bears the name of 

 the latter. 



As long ago as 1854, Dr. Staudinger pointed out in his 

 pamphlet " De Sesiis agri JBerolinetisis," that philanthi- 

 formis was attached to the common ling ; remarking *^prcB- 

 certim in calluna vulgari cernituri^^ but adding that it not 

 rarely occurred elsewhere, where this plant did not grow. 

 More recently, however, and subsequently to Mr. King's
