A. implora Grt. (46 i). Forewing light yellow, in the basal and costal-marginal areas tinted reddish 
with transverse lines broken up into single dots and a feeble faded median line. Hindwing white. New Mexico, 
Arizona. 
A. edentata Grt. (46 i) has broader wings of a deeper yellow with but one small purple brown spot 
behind the centre of the costal margin. Hindwing light brownish-yellow, at the margin deeper yellow. New 
Mexico, Arizona. 
A. aprepia Dogn. shows uni-coloured greyish-brown forewings without any marking except a fine 
brown marginal line being interrupted by the veins. Hindwing white, at the costal and distal margins a little 
strewn with brown. Expanse of wings: 29 mm. Argentina. 
202. Genus: Aiitaplaga Grt. 
Proboscis developed, the short porrect palpi are below somewhat hairy, the frons with a truncated 
conical horny projection with a raised margin and a central point, and a horny plate below it; the thorax is 
rather smoothly scaled and tuftless like the abdomen; the smoothly scaled anterior tibiae exhibit inside at 
the end a long bent claw; the structure is rather slender, with long and narrow fore wings. Quite a number 
of species have been described from Northern and Central America, which, however, are apparently not all 
quite homogeneous. 
A. pyralina Schs. (46 i) is one of the most beautiful species, forewing silvery green, strewn with blackish- 
brown, with dentate brown transverse lines bordered with silvery white, and white maculae, the silvery white 
undulate line being more or less divided into spots; hindwing brown with white-speckled fringes. Mexico. 
A. dela Drc. (46 i) has orange forewings with double dentate black transverse lines, the maculae 
surrounded with black, the cell between them more or less blackened, the fringes speckled black. Hindwing 
blackish-brown with whitish, feebly speckled fringes. — f. siigmatosa Dyar (46 i) is a form with conspicuous 
silvery whitish maculae, the ground-colour is somewhat more golden yellow, the double transverse lines more 
or less filled with blackish. This form is described from Mexico City. — f. hemicrocea Dyar (46 i) is marked 
exactly like the preceding ones, but all the black markings on the orange-yellow ground are of a somewhat 
deeper orange, nor are the fringes speckled black. It flies at the same place and time as the preceding form. 
A. atrolinea B. <b McD. (46 k) belongs yet to the preceding forms being distinguished from the 
type ( dimidiata) by a somewhat different frontal appendage, a transverse crescentiform projection with a 
vertical median listle and a horny plate below it. The colour and marking are similar, though the transverse 
lines are not so sharply angular, interrupted and not filled with blackish, the black cellular powdering being 
absent between the maculae which are not lighter than the ground-colour. Described from Arizona and probably 
only a northern race of dela. 
A. dimidiata Grt. (46 k) has more elongate fore wings with a more oblique distal margin, in the basal third 
white, behind it obliquely cut off cojjpery brown with a faded whitish subterminal band. Hindwing light brown 
with whitish fringes. Colorado. 
A. hachita Barnes (46 k) is on the forewing of a bright chrome-yellow with a white median band which 
is edged by the black transverse lines; minute black internerval spots are subterminal. Hindwing yellowish- 
white, at the margin somewhat darker. Arizona. 
A. sexseriata Grt. (46 k). Forewing all white, otherwise similarly marked as hachita with 2 intense 
black transverse lines; the subterminal row of spots is very distinct. Hindwing blackish-brown with yellowish- 
white fringes. Arizona. 
A. biundulalis Zell. (46 k) exhibits on the yellowish-white forewing 2 strong black transverse lines, 
the subterminal row of spots of the preceding species being absent altogether. Hindwing likewise yellowish- 
white. Texas. 
A. thoracica Edw. (46 k) initiates a group of quite uni-coloured unmarked species which are partly 
very difficult to separate, thoracica has an orange-yellow head and thorax, a brownish abdomen, and silvery- 
white forewings and hindwings, with an ochreous-yellow hue. Arizona. 
A. suffumosa Dyar (46 k) is larger than the preceding species, and on the forewing powdered with 
yellowish olive-brown; head and thorax are likewise orange, the hindwing is tinted brownish-grey. From Mexico 
City. — From Zacualpan there is a very similar, but throughout paler and smaller form which I denominate 
f . amaemica /. n. (46 k); here the forewing is lustrous silvery ochreous whitish, hardly powdered with olive, 
with almost white hindwings, though in the $ darker brownish-grey than in suffumosa ; head and thorax in 
the $ like the forewing somewhat more orange-yellow. 
A. salacon Drc. (47 a) is uni-coloured dee}) orange on the forewing and anterior body, the hindwing 
being lighter orange-yellowish, in the $ feebly powdered with brownish-grey in the disc. Mexico (Guerrero, 
Zacualpan).
