50 [August 



in accordance with my views respecting the internal arrangement of 

 lepidopterous Families, and which have resulted partly from a study 

 of the learned " Classification of the Coleoptera of North America," by 

 Dr. John L. Leconte, a work which, while it has been iguorantly styled 

 an " Elemeutar-Buch" by a German critic, possesses great originality 

 and lucidity of composition and arrangement, rendering it a very valu- 

 able addition to scientific knowledge. The genus CalUomma, closes 

 the Tribe 3Iacroglijssmi, while Pseudosphinx, inaugurates the more 

 typical Tribe of the Family — Sjjhingini. A fourth Tribe — Smtrin- 

 thini — is not represented in the present Collection, while I reserve an 

 amplification of this arrangement to a difterent Paper.

 Grreen. Anterior wings rather intense and vivid green ; nervules 

 in terminal space inconspicuously and minutely cotered with dark 

 scales, and boi'dered faintly with pale yellowish testaceous scattered 

 scales. Base of wing clothed with dark scales, forming a small, black- 

 ish, irregular patch extending to costa and mixed inwardly with paler 

 scales. Below, immediately on internal margin at base, is a small 

 though sufficiently prominent, somewhat elongated, pale-yellowish patch, 

 the scales composing which are long and hairy. 



The entire median space from costa to internal margin is of a vivid 

 green, concolorous, without markings except a small distinct pale yel- 

 lowish discal dot. 



A very oblique, wide, sub-terminal band runs parallel with external 

 margin from costa, where it is widest, spreading narrowly to the apex, 

 to the internal margin where it also widens narrowly as at costa, spread- 

 ing to internal angle, which latter is minutely fringed with pale yellow- 

 ish. This band is composed of brownish scales, which form a promi- 

 nent, costal, sub-triaugular patch and are mixed in parts with blackish, 

 and is traversed by blackish lines, the latter most distinct at the centre 

 in the 9 i where they are arcuate between the veins and the band is nar- 

 rowest. In the Z at the centre of the wing this band is obsolete and the
