Mr. J. W. Weiclemeyer for the information respecting this singular 

 little species, which, we believe, has not been hitherto described, while 

 an excellent figure, shown us by Mr. S. Calverley, enables us to present 

 the present description and to fix the species. It appears that Dr. 

 Boisduval has etiquetted a specimen in his cal)inet as Proaerpinus 

 Phaeton. 



Euproserpinus Phaeton. 



Size small ; anterior wings of a bluish shade, costa at base tinged 

 with testaceous. A blackish, regularly lunulate transverse line, ano-u- 

 lated below costa, runs inwardly obliquely from costa to internal mar- 

 gin at basal third. Between this line and the base of the wing are two 

 blackish parallel marks below costa. A few blackish scales on the 

 discal cross-vein. Median space even in width from internal margin 

 until above the angulation of the first transverse line, when it widens 

 to costa. Subterminal space pale brownish-testaceous, defined inwardly 

 by a distinct blackish transverse line, and similar to the front, exca- 

 vate between the nervules and slightly arcuate before costa. An in- 

 terior narrow line, furcate below costa; subterminal space raar"ined 

 outwardly by a very distinct, blackish, shade band which is slightly 

 sinuate and not excavate. Terminal space dull bluish, concolorous with 

 median. Posterior wings whitish, shaded with brownish testaceous at 

 base, and with an even, distinct, broad, black subterminal band, which 

 leaves a very narrow whitish terminal border and does not attain anal 

 angle. 



Tegulae, lined within with darker lines; corporale parts darker but 

 concolorous with primaries ; above, the abdomen shows some darker 

 shades; anterior tufts, of which the first extends across the abdomen 

 above, paler; those on anal and pre-anal segments, blackish. Exp. 1.50 

 inch. Length of body .65 inch. 



CHCEROCAMPA. 

 The species arranged under this genus may be resolved into three 

 groups. The first contains C. gun(Ua<:hil H-S. and C. invrata Grote, 

 in which species the anterior wings are not at all falcate; the external 

 margin is rounded and the ornamentation is modified, since a strai"-ht 

 narrow, subterminal, darker shade line is drawn across the win<is. The 

 second group contains apparently C. ncchntt, C. thalussinu, C. porcus 

 and C. nitulala. These are rather stout, heavy species, haviu"- the 

 external margin sinuate; the coloration is green and brown, with dif- 

 fuse spots and bands. The third group contains apparently C. pnicne., 

 C. versuto, C. tersa, C. rvhinsonii and C. falco. These are slender
