RIBALDIA; HYPERAESCHRA; ASTAPA. By Dr. M. Draudt. 
124. Genus : Kibaldin Dyar. 
Like Dothia, but the second and third subcostal branches, counted from below, on the fore wing are 
stalked. Only 1 species. 
Type of genus: R. amatame Dyar. 
R. amatame Dyar. Forewing Wood-coloured brown, strewn darker, with a prominently dark brown amatame. 
median area and a small elliptical light discal spot in it; only the posterior one of the transverse lines bor¬ 
dering on the median area is dentate on the veins; a subterminal row of black very indistinct spots. Hind¬ 
wing whitish, strewn with blackish at the margin, with a dark anal spot and pink fringe. Expanse of wings: 
39 mm. Mexico (Hidalgo). 
125. Genus: Hyperaeselira Btlr. 
This genus occurring in the Indian regions (Vol. X, p. 642) has also half a dozen of North American 
representatives. $ antennae pectinated to the tips, palpi hairy. Distal margin of forewing entire-margined ; 
neuration as in the preceding genera, but all the subcostal branches of the forewing are stalked except 
the uppermost. 
Type of genus: H. 'pallida Btlr. from India. 
H. stragula Grt. (= scitipennis Wkr.) (154 g) is a pretty easily recognisable species with violettish- stragula. 
grey forewings, reddish-yellow at the inner margin, with a chestnut-red basal spot and undulate line; basal 
ray deep red-brown, 2 subapical streaks also red-brown; fragments of the transverse lines are lighter grey. 
Hindwing brownish-grey with a red-brown marginal line. — f. manitou Neum. & Dyar has not the reddish- manitou. 
yellow tinge at the inner margin of the forewing, but it is more monotonously violettish-grey, it also lacks 
the chestnut-red basal spot, only single red-brown scales are at the undulate line. Hindwing lighter brown¬ 
ish-grey. Colorado, California. — f. pacifica Behr is a darker form with an almost black thorax, from Cali- -pacifica. 
fornia. — f. ochreata B. &■ McD., described from Utah, is lighter ochreous brown with a large bluish-black ochreata. 
spot behind the cell-end with 2 small whitish spots in it; marginal area and basal half of inner margin like¬ 
wise bluish-black, undulate line less undulate. Hindwing white with a bluish-black anal spot. — The larva is 
exactly like that of ziczac, lilac whitish-grey, marbled brownish, a brown dorsal line extends to the apex of 
the second protuberance; the last segments are raised and rusty brown mixed with yellow. It lives on 
willows and poplars. Widely distributed in the United States. 
H. georgica H.-Schdff. (154 h). Forewing greyish ochreous with a short silvery white basal ray and georgica. 
white dentate transverse lines bordered with black, the median area between them blackened in the inner- 
marginal half; 2 black subapical internerval streaks. Hindwing dingy white. Larva smooth, without protu¬ 
berances, green, irrorated yellowish-white, strewn with irregular dull red dots which are condensed into 
two lines; a yellow dorsal stripe bordered with red is very broad on the 5 th and the 7th and 8th segments. 
It lives on oaks in September. Its range extends from Maine to Texas. 
H. tortuosa Tepp. differs from georgica in the darker brownish-grey forewing without the white tortuosa. 
basal ray, the black transverse lines are scarcely dusted white, much more notched and irregular; the median 
area is scarcely darkened in the proximal half, but a broad faded red-brown median line is nearer to the 
postmeclian line; a black streak at the cell-end, and 2 subapical strong black internerval streaks. Hindwing whitish 
brownish at the margin. Colorado. 
H. tropicalis Schs. (154h). Eorewing brown with whitish hair, the darker brown transverse lines — tropicalis. 
a median line is double — are partly accompanied by small whitish spots; a dark longitudinal line extends 
through the cell, a few darker spots at the end, and a black line is at the cell-end with white scales behind 
it; the veins of the marginal area are blackened. Hindwing brown, reddish-yellow basally. Expanse of 
wings: 40 mm. French Guiana. 
126. Genus: Astapa Dogn. 
Two thirds of the antennae are provided with short ciliated pectinations; palpi rather long, hairy, 
with a short terminal joint. Forewing relatively broad with a rounded distal margin, with a long pencil¬ 
shaped hair-scale dent; neuration stated to be the same as in Ribaldia. Only 1 species. 
Type of genus: A. signata Dogn. 
A. signata Dogn. Forewing rusty yellowish brown, dusted with green at the costal margin, in the signata. 
cell-end, behind it and submedianly, blackish in the basal half of the cell, the veins strewn with black and 
white, marked very much like M. volcancita, with a black angular median line and an almost parallel post¬ 
median line composed of lighter internerval rings, a black cell-end streak and a double row of black subter¬ 
minal dots. Hinclwings blackish, fringe light, with a black and white anal spot. The species varies in the 
intensity of the marking, and in the colour which may even turn violettish-pink. Expanse of wings: 31—37 mm. 
Colombia.
