j\M^jOuis B. Prout on the 
somewhat projecting about lb'* and M’, then oblique basewards to 
inner margin at scarcely beyond one-half (thus near antemedian), 
sometimes accompanied distally by a weak and ill-defined brownish 
or greyish shade, which occasionally terminates on inner margin as 
a distinct spot ; in a few well-marked examples some dark vein- 
dashes on this shade, somewhat as in S. quisquiliaria, Quen. ; cell- 
spot minute, indistinct, sometimes obsolete ; a pale subterminal 
indicated in a few of the darkest examples ; terminal dark line fine, 
thickened into blackish dots between the veins. Hindwing usually 
slightly paler, especially in costal region ; terminal area usually con- 
colorous with that of forewing ; inner margin usually dark-shaded, 
especially in its middle, where there are nearly always the beginnings 
(often quite distinct) of two or three dark lines, which disajjpear at or 
before the cell; cell-spot sometimes rather large and distinct, some¬ 
times small and inconspicuous, occasionally obsolete ; pale sub¬ 
terminal indicated in the darkest examples ; terminal line with the 
interneural dots weaker than in forewdng. Undersurface nearly 
unicolorous fuscous greyish, hindwing somewhat paler and rougher- 
scaled than forewing, cell-spot usually present on both wings or at 
least on hindwing, sometimes quite conspicuous on the latter. 
Mendoza, La Paz, Palmira, etc.—mostly bred (W. M. 
Bayne), a large number in coll. L. B. Prout, coll. A. F. 
Bayne, etc.; type $ (excl. SeiAember 8, 1905) in coll. 
L. B. Prout. 
Mr. W. M. Bayne lias been very successful in breeding 
this species ex ovo on chrysanthemum ; the broods emerged 
May 1904, and August (end) to September 1905; 1 have 
also wild specimens from La Paz, March 1903, and 
Palmira, December 1903, and suppose there is a succes¬ 
sion of broods. Extremely variable, though always an 
obscure-looking little insect. One or two of the lightest 
specimens are virtually free from dusting, and marking¬ 
less; sometimes three approximated dark spots on inner 
margin (ends of antemedian, postmedian, and shade 
distally to the latter) are the only distinct markings. 
A typical Stenalcidia in structure, but with ^ hindtibia 
not dilated. Perhaps nearest to S. fusea, Warr.
