marginal area blackish-brown; before it is the strongly dentated undulate line. Fringes of hindwings at the 
apex brown, otherwise mixed with white. Expanse of wings: 18 mm. California. 
St. aterrima Grt. (26 1) probably also belongs hereto, and not to Pseudacontia. Forewing blackish- 
brown, somewhat irrorated with grey, with rather indistinct black transverse lines, the posterior line double 
and filled up with white, behind it extensive white irroration; the small maculae are brown, surrounded by 
black; instead of the undulate line there are minute white spots with black ones before them. Hindwing blackish- 
brown with an indistinct lighter median line. California. 
18. Genus: Cerapoda Sm. 
Distinguished from the neighbouring, closely allied genera by long claw-like spines on the outside 
of the first 2 tarsal joints. The scaled thorax exhibits loose tufts in front and behind, the abdomen shows a 
tuft on the first abdominal ring. Otherwise entirely like Oncocnemis. North American. 
C. oblita Grt. (= strigata Hold, nee Sm., deserta Grin., insertans Sm.) (27 a). Forewing on the greyish - 
white ground irrorated with ochreous and strewn with blackish-brown, the veins darkened; a black basal ray 
is fused with the lower end of the long pointed coniform macula, above it a white patch in the cell; no transverse 
lines; end of median and the transverse vein are marked white, the ring-macula is oblong, pointed; subterminal 
area on both folds tinted yellowish; the apex is parted by an oblique whitish blotch. Hindwing white with 
brown veins and margin. The species varies somewhat. — The form arrosta Dyar has a still longer ring-macula 
and a thicker white streak at the end of the median, and in the marginal area there are round dark internerval 
spots distally bordered with white. Hindwing a little darker. -— Nevada, Colorado, California. 
C. strigata Sm. (— oblita Dyar nec Sm.) was described as a Calophasia. It is very similar to the 
preceding, smaller, with darker and more uniformly grey forewings, in the region of the reniform macula the 
thick white streak of oblita is entirely absent. Expanse of wings: 30 mm. Colorado. 
C. stylata Sm. (27 a) is considerably larger than oblita. , more blackish-brown, in the marginal area 
still darker, on the submedian fold white-striped, and with entirely faded transverse lines; the maculae are 
small, whitish, surrounded by black, the white crenulate undulate line is proximally bordered with blackish. 
Hindwing white, at the margin narrowly brownish. Colorado. Nevada, Utah, New Mexico. — arida B. & Benj. 
is a small, very pale, brownish yellowish-white desert-form from California. 
19. Genus: Hoinoiieociieiuis Hmps. 
Distinguished from the allies by the thorax being clad with hair and hair-like scales without tufts, 
the abdomen being neither tufted. The anterior tibiae outside show a bent spine. Only known from North 
America. 
H. fortis Grt. (= vorax Behr) (27 a) is a larger species with dark brown, lustrous purple wings, the 
transverse lines marked by vein-dots without maculae, the undulate line marked by small black diffuse spots. 
Hindwing white, on the veins and margin irrorated with golden brown. California, Nevada. •— The thin brown 
or grey larva with 2 rows of black longitudinal dots and a metallic green ventrum lives on ash-trees. -— The 
form picina Grt. has no small black undulate linear spots and no black marginal dots and a less curved 
postmedian row of dots. Arizona. 
H. psaphidioides Dyar (27 a) has brownish-grey forewings with a white undulate line near the margin, 
a black basal and anal ray and a black median shade, black dentate transverse stripes, the anterior stripe being 
double and with large light, black-ringed maculae; veins in the marginal area black striped. Hindwing white 
with a blackish-brown marginal line. It recalls an Acronycta. From Mexico (Zacualpan). 
20. Genus: Copitarsla Hmps. 
Very closely allied to Cerapoda from which it chiefly differs in the thorax being clad with hair and 
hair-like scales; besides only the first joint of the anterior tarsi shows on the outside bent claws. Half a dozen 
species of a very uniform insignificant exterior are known from tropical and southern America. 
C. humilis Blch. (27 a) is the palest of the allies, forewing narrow, yellowish white, irrorated with 
red-brown, the markings are feeble, transverse lines double, crenulate, the posterior line distally with vein- 
dots or streaks, the maculae entirely faded. Hindwing diaphanous white with yellowish veins, in the $ more 
brownish. Chile.
