margin; the feeble smoky grey postmedian line is near the margin and almost parallel to it, with a bend 
towards the apex below 8; discal spot white, hindwing cinnamon-brown. The larger $ is of a much duller 
brownish colour and scantily scaled, the postmedian line broad, indistinct. Hindwing without markings. The 
female type of leucostygma lacks the bend of the postmedian line below the costal margin to the apex, it is about 
3 mm distant from it, and the hindwing exhibits a distinct transverse line from below the apex straight to the 
first third of the inner margin. Dampf who bred the species on oaks from larvae occurring destructively in the 
State of Tamaulipas will supply an exhaustive description. 
A. consularis Dyar (142 f) is very similar to senatoria. Body brownish ochreous, wings dark purple 
brown, behind the round white discal spot a faintly diaphanous area; marginal area more violettish-grey. 
Hindwing rounder than in senatoria, not angular, posterior transverse line more indistinct. The $ is of a duller 
yellowish brown, basal and marginal areas scarcely darker, speckled darker, the white discal dot small. Larva 
reddish flesh-coloured or reddish brown, granulated white, with black longitudinal bands, the dorsal and 
stigmatal ones darker and more distinct, bordered with white beneath, horns black. On oaks. Florida. 
A. virginiensis Dm. (= astymone Oliv., pellucida Abb. & Sin.) (142g). $ with a large hyaline area 
behind the discal spot, the white spot at the cell-end very large; deep purple brown, somewhat lighter in the 
narrow marginal area. $ thinly scaled, lighter brown, base and margin with a feeble lilac tinge, scarcely 
speckled. Larva as in stigma, but the head is green, the body more greenish, the stripes more pink; on oaks. 
Atlantic States. 
A. oslari Rothsch. (= skinneri Biederm., neomexicana Brehnie ) has the same shape as virginiensis, the 
body deep ochreous; fore wing reddish-brown with a silvery white discal spot; a narrow bluish band 4 mm 
distant from the distal margin and parallel with it. Hindwing deep purple brown. The $ is larger than the 
and lighter. Head, prothorax, and abdomen ochreous, mesothorax and ventrum more loamy reddish-yellow. 
Fore wing above the same, base and posterior transverse line very feebly grey; stigma white, round; wings not 
striated darker, margin straighter, anal angle less round than in stigma. Hindwing with a slight reddish hue, 
without distinct lines, costal margin longer than inner margin. Expanse of wings: 53, $ 71 mm. Larva 
reddish-brown, at last dull red, young larva without horns, only with dark dots where they grow later on; 
it lives on black oak. 
A. dissimilis Bsd. (= suprema H.Edw.) (142 g). The forewing is red-brown, with black veins, an 
oblique black posterior transverse line and a large white discal spot; hindwing black. Thorax reddish-yellow, 
abdomen black with a reddish-yellow anus. The $ forewing light cinnamon reddish like the thorax, marginal 
area lighter, with distinct darker veins, a large round white cell-end spot, the feebly curved greyish-black 
postmedian line somewhat white-scaled distally. Hindwing dark reddish-grey, with black veins, a broad black 
antemedian shadowy band. Mexico, widely distributed. 
A. assimilis Drc. (142 g) is allied to dissimilis, but the body, forewings and hindwings monotonously 
reddish-brown, the hindwing somewhat darker, the white discal spot of the forewing much less distinct, the 
veins not darker. Only the is known, apparently very rare and hitherto only reported from Chihuahua. 
Eacles tricolor Wkr. and Eacles suffusa Wkr. have remained unknown, nor could Mr. Schaus supply any infor¬ 
mation about them. 
Subfamily: Oxytenidae Jord. 
This subfamily and the following one are entirely unlike the usual Saturnid type and frequently 
resemble partly Geometrid genera, such as the extremely variable Oxydia, or Urapteryx, partly certain Uranid 
forms as found in the African and Indo-Australian Regions. We treat these insects as a deviating branch of 
the Saturnidae, whilst Jordan, in his most excellent and exhaustive treatise *), prefers to raise it to the rank 
of a family. Anybody that is particularly interested in this group cannot do without studying this monography. 
As a matter of course, we cannot enter into the finer anatomical details, especially the genital differences, 
except in a most brief way and we therefore refer expressly to the said work the arrangement of which we 
observe in the following. The species which, according to Jordan, exhibit certain antique features are 
chiefly separated from the other Saturnioidae by a mostly rather strong convolvent tongue, the antennal shaft 
being scaled as far as the tip, the antennal pinnae (being developed in both sexes) arising on the ventral side, 
and the well developed precostal branch on the hindwing; the palpi are relatively long. The larvae living on 
Rubiaceae are very peculiar and quite different from the other Saturnidae-, resting contracted on leaves they 
resemble the droppings of birds. The 3rd segment is strongly expanded anteriorly and beneath and exhibits 
2 ocelli, the penultimate segment bears a curved horn which is often bipartite at the end. The pupa spins itself 
with a few threads in a convolute leaf.
