taking 21,000,000 feet for the radius of the earth, instead of 

 20,920,000. This is involved in his solution, as well as the 

 assumption that the earth performs a rotation in twenty-four 

 hours instead of 23"^ 56™ 4% which in conjunction will pro- 

 duce the slight effect just noticed. I am yours, &c.

Genus 88. ENNOMOS, Ochs., Treitsch. 



(Ennoinios, Geometra, Pericallia, Bradypetes, 



Macaria, Stephens. Macaria, Curtis. 



Ennomos, Aventia, Philobia, Timandra, Epione, 



EuRYMENE, RuMiA, Angerona, Duponchel.) 



Wings not, or scarcely at all, deflexed when at rest ; the in- 

 ferior with a prominent angle at the posterior margin ; the 

 underside generally ornamented, with lively colours. — Larva, 

 with the body tubercular, tapering towards the head, which 

 is prominent, rather broad, and depressed. — Pupa follicu- 

 lated, not subterranean ; generally changes in a slight web 

 attached to the leaves of plants. 



0^5. The preceding long list of synonyms shows sufficiently 

 the concurrent opinions of many authors as to the neces- 

 sity of breaking down this genus into several new ones; and 

 M. Treitschke himself seems to admit their accuracy, since 

 he has adopted no less than five families or subdivisions to 

 receive the species, according to the form of the wings, 

 their markings, &c. demonstrating how inefficient, even in 

 his own estimation, are the very meagre chai'acters which 

 (as above) he has prefixed to the genus. 



Fam. a. — Fore wings horizontally extended, — hind wings 

 rounded. 



Fa.m. B. — Fore wings extended, — hind wings angular. 



Fam. C. — All the wings indented. 



Fam. D. — Crescent-shaped markings or maculae on the disc 

 of the fore wings. 



Fam. E. — All the wings indented, — the dentations of the fore 

 wings particularly strong. 



We shall, as usual, give the characters of tlie new genera (if 

 published) in foot-notes, as the respective species occur on 



which
