C. oaklandiae B. <0 Me. D. (5 d) is also very similar to fascia, it is smaller, neater, but more indis¬ 
tinctly marked, and the basal and marginal areas are not contrasting by a lighter colour. The hindwing is 
darker smoky with an oval discal spot, not a small crescent. From Oakland (California). 
C. nana B. & McD. (5 d) is the smallest species with a light ochreous ground of the forewing, in 
the discal and marginal areas strewn somewhat with brown, with dark costal spots; the maculae are encircled 
with orange, the anterior transverse line is proximally, the posterior line distally bordered with orange, whereby 
it is easily discernible. Hindwing brownish. Expanse of wings: 19 mm. Described from California. 
C. sarepta Barnes (5 d) has bronze-brown forewings with light green basal and postmedian areas, 
as well as a reniform macula. Hindwing brownish-grey. From Arizona. 
C. fascia Sm. (4 g) has a white head and thorax, and on its olive yellowish ground it is dusted with 
blackish brown at the base and in the discal area as well as in two spots in the marginal area behind the cell 
and analwards; the maculae are large and encircled by white. Hindwings dusted with brown. The $ is 
darker with much more indistinct markings. 
C. marina Sm. Forewing brownish-grey, intermixed with black and amethystine scales, in the discal 
area darker, both the maculae large, strewn with green — like the shoulder-covers —, the transverse lines grey 
bordered with black. Hindwings whitish-grey. Expanse of wings: 26 mm. Arizona. 
C. cuerva Barnes (5 d) has dark brown wings strewn with olive-green, black, and white. Transverse 
lines black, dentate, the posterior line distally bordered with white; the maculae are only traceable by black 
scales. Fringes speckled white and brown. Hindwing brownish-grey with a dark discal spot and posterior trans¬ 
verse line. Canada, United States to California. 
C. albipuncta B. & McD. (5 d) is somewhat like marina, but it has no green in the maculae and 
is well recognizable by the invariably white reniform macula and more strongly combed antennae. The ground¬ 
colour is a deep sepia-brown, strewn with grey and olive, in the marginal area somewhat lighter. The transverse 
lines are black, dentate, bordered with whitish. Hindwing dark smoky grey. Described from California (S. 
Diego). 
C. olivacea Sm. (5e). The whitish forewing is thickly strewn with blackish brown and intermixed 
with single orange-red scales; maculae and transverse lines black, encircled and bordered with whitish. Hindwing 
whitish, dusted with brown, in the marginal area darker. From Colorado and California. 
C. galva StrecJc. is said to look very much like Acronycta fragilis (3 e). White, on the forewing strewn 
with black, the maculae and transverse lines distinctly marked black, the fringes speckled white. Hindwing 
with a grey marginal area, discal spot and transverse line behind it. Expanse of wings: 28 mm. From New York. 
C. pallida B. <£■ Lindsey is not allied to any of the other species, the most closely allied it is apparently 
to galva. Forewing yellowish-white with black transverse lines, behind the anterior line and at the most distal 
basal area strewn with brown; ring-macula oval, reniform macula very long, strongly bent; at the distal margin 
between the veins black diffuse sagittae. Described from Arizona. Expanse of wings: 27% to 30 mm. 
C. canoa Barnes (5 e) has been placed by Hampson to the genus Namangana. On the grey forewing 
strewn with blackish-brown, the lines and maculae are prominently whitish; fringes speckled grey and white. 
Hindwing dark brown. Described from Arizona. 
6. Genus : Metaclirostis Him. 
This genus being better known as Bryophila Tr. contains but 1 American species distinguished from the 
preceding only by its longer palpi. The abdomen is only tufted on the first rings. 
M. semifascia Sm. (4g) is light reddish-brown, strewn with whitish, well recognizable by a white 
spot in the proximal half of the discal area; the transverse lines are blackish, the anterior line proximally, the 
posterior distally bordered with grey, the maculae indistinctly encircled with grey. Hindwing white, on the 
veins and border dusted with brown. Only known from Colorado. 
7. Genus: I*«lyg;raiiiiiiafe Hbn. 
Proboscis developed; palpi slender, obliquely rising; the frons exhibits a transverse ridge in the centre, 
below it a horny plate; antennae plain, not ciliated. Thorax smoothly scaled, without tufts, only one on the 
1st abdominal ring. The veins do not differ from the usual scheme. Only one species: 
P. hebraicum Hbn. (5 e) on its silvery white wings shows scanty, distinct, black markings. Hindwing 
yellowish-white, dusted with brown, towards the margin darker. United States from Massachusettts to Florida
