bent subterminal band which in the centre runs close at the margin, and recedes farther at the apex. Hindwing 
in the disc broadly yellow, with a small grey basal spot and dark grey marginal half. Expanse of wings: 27 mm. 
Venezuela (Merida). 
Line 18 from above, to Cisthene menea : 
C. arida Skinn. is to be cancelled from the synonyms and becomes a distinct species. The abdomen arida - 
is quite yellow, the hindwing in the basal half. The median band of the forewing is narrow, the subterminal 
band before the anal angle rounded, terminating as a spot. From Arizona. 
After it insert: 
C. chorion Dyar (66 k) is at once discernible from arida by the abdomen beneath being grey, chorion. 
Forewing slate-coloured black with a moderately broad orange-yellow median band and a rather broad suit- 
terminal band which is shortened at the anal angle. Expanse of wings: 33 mm. Mexico (Guadalajara). It 
may be a form of arida. 
C. loccea Schs. (66 k) is closely allied to menea (35 i). Body of a deep yellow with black legs. Forewing loccea. 
brownish-black, median band and subterminal band narrow, the median one almost vertical, scarcely widened 
at the costal and hind margins, the subterminal one the broadest at the costal margin, very much nearing each 
other below the distal margin. Hindwing of a deep yellow, with a black marginal band of about 2% mm width. 
Expanse of wings: 27 mm. Guatemala. 
Line 21 from below, after Cisthene -praxis insert: 
C. tehuacana Dyar (66 k) differs from the following cypris (35 i) in the almost quite black hindwing tehuacana. 
with but a small yellow costal spot. Forewing slate-coloured greyish-black, with a narrow yellow median band 
and a short crescentiform subterminal band. Head and thorax yellow, abdomen black except the base and 
the apex of anus. Expanse of wings: 24 mm. Mexico, Tehuacan (Puebla). 
Line 17 from below, after Cisthene unicincta insert: 
C. ducei Schs. (66 k) is bluish-black on the body and wings, whilst the vertex, collar and some hairs ducei. 
on the metathorax as well as the segmental indentations on the abdomen are orange; the median line on the 
forewing is 2 mm broad, straightly extending from the costal margin to the hind-margin; the subterminal band 
is still narrower and ends pointedly at the anal angle. Hindwing with a bipad orange transverse band in the 
basal half from the costal margin to the hind-margin. Expanse of wings: 35 mm. Colombia. 
Line 1 from below, after Cisthene triplaga insert: 
C. abdulla Dyar (39 1) is monotonously black, on the wings a slight slate-coloured reflection, with a abdulla. 
yellow basal spot from the subcosta to the median, the hindwing with a small yellow costal stripe in the basal 
half. Expanse of wings: 26 mm. Mexico (Cuernavaca). Probably this insect coincides with Cyanarctia basi- 
plaga = Hypoynolis lithosiaphila. 
P. 274, line 12 from above, after Gnamptonychia orsola insert: 
Gnamptonychia ventralis B. ds Linds. Forewing greenish black, in the $ greyer, hindwing dull brownish- ventralis. 
black. Anterior body likewise greenish black, the head, antennal base, palpi, collar, hips, femora, hind tibiae, 
and the underside of the thorax and ventrum of a bright orange. Expanse of wings: 38 to 45 mm. Arizona. 
This species is certainly very closely allied to G. orsola (32 i). 
After this add: 
62a. Genus: (nrucia Dyar. 
Allied to Gnamptonychia, but without an accessory cell on the forewing which shows the two lower radial 
branches forked; the uppermost subcostal branch unites at the end with the costal vein. But one species: 
G. monacheicauda Dyar (66 k) is unicoloured dark slaty-grey on the body and wings, the anal tuft monachei- 
is ochreous. Expanse of wings: 37 mm. Mexico (State of Hidalgo). cauda. 
P. 275, line 25 from above, before Pronola insert: 
66a. Genus: Yill mam Schs. 
To be compared with the Indian genus Haloyie (Vol. X, p. 186). Proboscis developed; the slender palpi 
erect, not reaching to the vertex. Forewing narrow with a straight costal margin, the upper median branch 
rises from before the lower cell-angle which sends forth the two lower radial branches, the uppermost rising 
from the upper cell-angle; the 3 lowest subcostal branches are forked, the two upper ones separate. Hindwing 
similar as in Pronola, but the middle radial rises directly from the lower cell-angle, the upper one is forked 
with the subcostal. 
V. drostana Schs. (66 k) is quite monotonously blackish-brown, only on the forewing with a slight drostana. 
purple tinge. Expanse of wings: 18 mm. Guatemala.
