Ch. ingenua Smith (2 b) is likewise very similar, but the forewing with a more bluish-grey ground- ingemm. 
colour, the antemarginal line only feebly undulate, not so strongly dentate as in the other species. Hindwings 
much lighter. Colorado. 
Ch. deridens Gn. (= circulifera Wkr., contigua Wkr.) (2 e) looks like jalapensis, but it is of a quite deridem. 
light ground-colour, slightly yellowish. From Canada to Florida and Texas, to the west as far as Colorado, 
flying from May to July, in Canada already in February. — In the form fumosa form. nov. the inner-marginal fumosa. 
half of the discal area and the space behind the posterior transverse line are darkened. — Larva, varying from 
whitish to greyish-black, without markings or in dark specimens with white dorsal spots, exhibits long white 
silky hair on grey tubercles, with single black lateral hairs. It lives in October on oak, birch and elm trees. 
Ch. sudena Smith is a smaller species with fainter transverse lines; the connecting streak on the sub- sudena. 
median fold is mostly absent, the small light ring-macula is entirely unpupilled, and the antemarginal line more 
regular. Florida. Expanse of wings: 34 to 36 mm. 
Ch. nigracreta H. Ediv. (= rhotana Ere.) (2 c) differs by the chalky white ground-colour and a blackish- nigracreta. 
brown, triangular costal spot being mostly united with another one coming from the proximal margin. Hindwing 
dark brownish-grey. Mexico, Guatemala, Costa Rica. From Mexico there are entirely white specimens before 
me: creta form. nov. (2 c) and from Costa Rica such exhibiting only the dark triangular costal spot: triangulum creta.

Ch. dispulsa Morr. (2 c) differs by the intense yellowish tinge of the forewings and entirely light hind- disputsa. 
wings. From Texas in apparently 3 generations from March to October. 
4. Genus: lialliyra Wkr. 
It contains the largest and strongest species of the subordinate group characterized by hair-tufts on 
the pro-, meso-, and metathorax; the abdomen is likewise tufted, and the largest hair-tuft is on the 3rd ring. 
All the rest like in the other genera. Hitherto only 2 southern species are known. 
B. sagata Wkr. (2 d) is a large, beautiful, variegated species well recognizable from the figure, sagata. 
It is widely distributed from Mexico through Colombia, Venezuela, Surinam to Peru, also in Santo Domingo. 
B. chavannesi Fldr. (2d) differs from the very similar preceding species by less orange dusting and chavannesi. 
a distinctly marked reniform macula which is in sagata only indicated by small black and white spots. Described 
according to a specimen from Brazil. 
5. Genus: Cnaujoiiia Dyar. 
Recognizable by the untufted thorax being only covered with hair, and by the upper radial of the forewing 
rising from below the upper cell-angle. The genus only contains 4 species being very similar in the exterior, 
with diaphanous forewings. 
G. arbosi Dogn. (2e) has diaphanous forewings with yellow, black-dotted veins; the transverse lines arbosi. 
are traceable by a more intense dotting, only in the $ they are somewhat more distinct. Colombia, Ecuador, 
Peru. 
G. arbosioides Dogn. (2 e) differs by the forewings being tinted sulphur-yellow with distinct dentate arbosioides. 
transverse lines. From Colombia and Ecuador. 
G. vau-nigrum Hmps. (2 e) has somewhat less yellowish forewings, otherwise very similarly marked, vau-nigrum. 
but well discernible by the V-shaped black spot at the rise of the lower median vein. Colombia, Venezuela, 
Peru. 
G. renifera Hmps. (2e) is the same, but it has a blackish-brown abdomen and a moon-shaped black renifera. 
filling of the reniform macula. Described from Southern Peru. 
6. Genus: Iiaclinoptera H.-Schaff. 
Distinguished from the preceding genus by the thorax being intermixed with hair-shaped scales and 
by the uppermost radial rising from the upper cell-angle. 
L. cavillator Wkr. (= bivaria Wkr.) (2 g) is an extremely variable species the forms of which are cavillator. 
regarded as distinct species by Hampson, though 1 am of a different opinion; many hundreds of specimens 
have passed through my hands, all the forms denominated are connected by the slightest transitions, so that 
a distinct delimitation is impossible. The nomenclatural type has white forewings with torn black transverse
