7230 Notices of New Boo\'S, 



for dividing these vast tribes by any hypothetical number ; and should 

 he peruse the labours of Dr. Horsfield he will find that that accom- 

 plished entomologist's attention was directed entirely to the larger 

 insects — the Papiliones, Sphinges and Bombyces — and will, I think, 

 not fail to conclude that Dr. Horsfield crowded together the Geometrse, 

 Pyrales and Micro-Lepidoptera simply because he had not studied 

 them. 



This work, therefore, although containing the results of a long life's 

 labour and study, can only be regarded, j^r^^, as furnishing us with 

 unquestionable details of metamorphosis, and, secondly, as giving us a 

 continuous and digested list of the Papiliones, Sphinges and Bom- 

 byces yet ascertained to be inhabitants of the East. This latter labour 

 has devolved almost entirely on Mr. Moore, and I am sure every ento- 

 mologist will appreciate highly the great industry, the sterling ability, 

 and the extreme modesty with which his task has been accomplished. 



Reverting to the divisions of the larger Nocturnes, it seems evident 

 to those who desire thoroughly to understand them that the larva offers 

 the best character for dividing them into groups ; and if we give Dr. 

 Horsfield's first group the meaning which its name implies, " Sphinx- 

 formed," we shall then have eight perfectly natural divisions, and we 

 shall find in each a heliophilous, a heliophobous and other intermediate 

 groups, which may be indicated by placing them in parallel columns.

Linneus, misled by exclusive attention to the imago, placed all 

 the heliophilous families in his genus Sphinx, as well as those which 

 possessed the Sphingiform larva ; and he thus included a portion of 

 each natural division ; so that Smerinthus, Sphinx and Macroglossa 

 were Sphinges on account of the larva; Macroglossa, Sesia (^Egeria 

 of Fabricius), Zygaena and Glaucopis were Sphinges on account of 

 their imago ; Macroglossa alone possessing a double claim. All the 

 eight larval divisions of Nocturnes are probably susceptible of similar 

 subdivisions, not indeed into three, but into several groups; but we 

 are compelled to wait for a more perfect knowledge of their metamor- 

 phoses. 



Those few entomologists who have glanced, even for the purpose 

 of condemning it, at my septenary hopothesis, will recollect that Sphinx
