an opportunity once missed of coining names for three hundred 

 new orders, (and each might have been a combination of conso- 

 nants which no one could spell, or speak, or read, or understand,) 

 alas ! alas ! may never occur again. 



To return ; I suppose the sub-class Phalaena to contain seven 

 natural orders, a number precisely similar to that discovered 

 from observations made on the larva by that most accurate and 

 indefatigable naturalist. Dr. Horsfield ; * and I may add, my 

 own divisions are derived from the same source, together with 

 the pupa and whole habit : the perfect insect has no characters, 

 hitherto discovered, by which we can ascertain either sub-class 

 or order, and from this circumstance I am compelled to omit 

 those genera of whose larvae I am ignorant, f and even to leave 



* I regret not having Dr. Horsfield's work to refer to ; but I believe I am 

 perfectly safe in stating from memory that these seven he considered typed in 

 the genera, Saturnia, Lasiocampa, Cossus, Cerura, Arctia, Laria, and Lima- 

 codes : two of these he manages to unite to other two, in order to reduce the 

 number to five, but I forget which. 



f As the genera which I must mention ought necessarily to be drawn 

 entirely from one work, in consequence of authors diifering as to their con- 

 tents, I have adopted those in Mr. Curtis's Guide, invariably: below is a 

 list of the genera he has given in this section, with my own idea of their situa- 

 tion attached to each, and the addition of six genera, which Mr. Curtis does 

 not consider as belonging to the sub-class Phalasnse :
