58. Genus: Couistra Hbn. 
This genus being also known as Orrhodia Hbn. is also represented in America by a number of species. 
They entirely resemble the species of Epiglaea, but the prothorax exhibits at most quite feeble indications 
of a somewhat keel-shaped tuft, or it is entirely absent. The abdomen is very flat, smoothy scaled, without 
tufts. Cf. also Vol. Ill, p. 145. 
C. inulta Grt. (29 e) is a large red-brown species with purple blackish-brown transverse lines, very 
large, often confluent maculae encircled with red-brown, a reddish-brown undulate line and before it dark 
veins. Hindwing red-brown with reddish fringes. Canada, United States. -— The dingy brown larva with a 
whitish lateral stripe lives on guelder-rose. 
C. viatica Grt. (29 e) is still larger, very similarly coloured and marked, but the transverse lines, parti¬ 
cularly the posterior line, are crenulate, the posterior line being distally irrorated with dark; the ground-colour 
is somewhat more irrorated with whitish, the maculae are finely surrounded with whitish. Hindwing dark 
brown, fringes with a slight pinkish tint. United States to the Southern States, Texas. -— The larva is of a 
dingy greenish colour with faded chessboard-like darker markings. It lives on oak etc. 
C. adulta Gn. is a doubtful North American species which was described according to a manuscript 
plate of Abbot and looks like viatica-, the larva is also figured there on a low plant, not on oak. For the present 
we cannot give any further particulars about this species. 
C. signata French (29 f) resembles viatica, but it is much smaller with broader wings, more purple 
grey irrorated with redbrown, the black transverse lines on the averted sides bordered with grey, the ring-macula 
much smaller. Hindwing blackish-brown with reddish fringes. Central States. 
C. tristigmata Grt. (29 f) is smaller than the preceding, irrorated more yellowish-grey, the anterior 
transverse line indistinctly double and almost straight; the black filling of the lower end of the reniform macula 
distally shows a white dot; the coniform macula is very small; the light undulate line is on both sides bordered 
with brown. Canada; North-Eastern States. •— The larva is dull blackish with indistinct lighter dorsal and 
subdorsal lines, a broad lateral stripe being tinted orange-yellowish. 
C. sidus Gn. (29 f). Forewing bright brick-coloured reddish, strewn with blackish-brown with darker 
striped veins, dark, finely crenulate transverse lines, without a ring-macula with a yellow reniform macula, above 
and below generally with white dots; the indistinct light cremdate undulate line is proximally irrorated with 
brown. Hindwing brown with ochre-reddish fringes. Canada to Texas. •—- The larva is dark red-brown with 
indistinct light dorsal and subdorsal lines and a faded light yellow lateral stripe. -— In the form vinulenta Grt. 
the reniform macula is white instead of yellow. — walkeri Grt. is a dull ochreous grey form with a faded and 
indistinct marking and may only represent hibernated specimens. •— Colorado Sm. (29 f) is a reddish loam-coloured 
or ferruginous-yellow form with quite extinct markings from Colorado. 
C„ morrisoni Grt. (29 g). Forewing light greyish-brown, irrorated with reddish-yellow, with hardly 
darker transverse lines being whitish on the averted sides, and a narrow white small luna instead of the reniform 
macula, which exhibits a blackish spot below; the light crenulate undulate line is proximally shaded with brown. 
Hindwing greyish-brown with reddish fringes. Canada; Massachusetts New York. •— The blackish larva has 
distinct whitish dorsal and subdorsal lines and a white lateral stripe. -— Whether castanea Strd. ( = ab. 1 Hmps.) 
with chestnut-red forewings and deeper red fringes of the hindwings belongs to it, is questionable. 
C. devia Grt. (29 e) has darker purple brown forewings strewn with whitish-grey, with a browner 
central and marginal area with whitish transverse lines and absent median line; instead of the reniform macula 
a small luna in a whitish ring; before the whitish undulate line there is another oblique whitish line. Hindwing 
greyish-brown with yellowish fringes. Canada; North-Eastern States. — The larva is brown with whitish lines 
and lateral stripes, which are distinctly bordered with dark brown. 
C. fringata B. d; McD. (29 g) is most similar to devia in the marking, but it is much larger with redder 
fringes. Forewing of a bright reddish-brown, in the basal area strewn with grey, with lighter narrow, almost 
straight transverse lines and a long narrow reniform macula distally bordered with light yellow; before the 
yellowish undulate line an olive-grey shadow proximally bordered by a broad whitish line. Hindwing smokv- 
grey with contrastingly brownish-red fringes. California. 
C. indirecta Wkr. (= moffatiana Grt.) (29 f). Forewing ochreous, densely irrorated with red, with reddish- 
brown striped veins, red-brown transverse lines, the maculae surrounded with red-brown. Hindwing paler 
reddish-yellow, with yellowish-white fringes. Canada and North-Eastern States. 
C. graefiana Grt. (29 g) is closely allied to indirecta and has been frequently mistaken. It is invariably 
of a purer yellow, the red transverse lines are straighter and thicker, the hindwings are paler yellow. Of the 
same range as the preceding, as far as Massachusetts. — The white larva with faded light yellow transverse 
rings lives on Hamamelis.
