A. subflava Grt. (46 b) is smaller than the preceding species, with a larger reniform macnlar dot subflava. 
at the lower cell-angle and more distinct rows of dots instead of the two transverse lines, an undulate line is 
indicated by the marginal area behind it being darkened, no marginal dots. Canada and United States as far 
as South Dakota, Illinois, Wisconsin. 
A. alameda Sm. (46 b) is still somewhat smaller on an average, with dull red-brown forewings strewn alameda. 
with a darker brown, the veins striped blackish, quite obsolete maculae, and only a posterior row of vein-dots. 
Hindwing ochreous-brownish. The $ has a yellower tint with more distinct markings, particularly the post median 
dots are large and often bordered with white. California. 
A. laeta Morr. (46 b) has bright red-brown forewings with brown striped veins without any row of laeta. 
dots, only at the lower cell-angle there is a small darker spot. Hindwing reddish-ochreous, strewn with brown. 
New Jersey, New York. 
176. Genus: €ca Grt. 
Distinguished by the developed proboscis, plainly rounded frontal projection with a horny plate below 
it; on the thorax being clothed with hair and hair-like scales, there are loose tufts in front and behind. Abdomen 
tuftless. Three purely North American species. 
C. immacula Grt. (46 c) is a uni-coloured yellowish-white insect most rarely exhibiting traces of immacula. 
faint marking. Hindwing white with a silky gloss. Arizona, New Mexico. 
C. Colorado Sm. (= leucanidia Hmps.) (46 c). This species having formerly been regarded as Arsilonche Colorado. 
belongs to this place; forewing very light yellowish, with a feeble reddish tint, somewhat lighter veins and 
single darker internerval streaks in the marginal area. Hindwing yellowish white. Colorado, Oregon. 
C. cirphidia Hmps. (46 d) differs from Colorado in the somewhat darker total colouring with black cirphidia. 
irroration and some black dots in the cell-end. California. 
177. Genus: Calamia Hbn. 
This oldest name having been established in 1822 for the palearctic species Rhizedra lutosa and 
phragmitidis must be maintained instead of the name introduced by Hampsox : Arenostola. Separated from 
the preceding genus by more erect palpi, a smooth frons only provided with a hair-tuft, and a tuftless metathorax. 
As to this genus cf. also Vol. Ill, p. 234. 
C. inquinata Gn. (= orientalis Grt.) (46 d). Forewing ochreous-reddish, strewn with black, the veins inquinata. 
striped whitish, and a black longitudinal stripe in the upper half of the cell; a similar stripe is submedian in 
the discal area, and an indistinctly bent postmedian line reaches to it. Hindwing ochreous brownish. Canada 
to New York and Buffalo. 
C. orphnina Dyar is uniformly and densely powdered with grey on the dingy yellowish ground, so that orphnina. 
the markings are almost covered; these markings consist of darker striped veins and a postmedian row of dots 
as well as a white dot at the lower cell-angle; along the costal margin and from the median vein towards the 
margin there are darker nebulous patches. Hindwing light grey. Expanse of wings: 27 to 32 mm. New Hampshire. 
C. variana Morr. (46 d) is very similar to inquinata and merely differs in the absence of the posterior variana. 
transverse line. Michigan. 
C. defecta Grt. (46 d) is a somewhat larger light reddish grey species shaded with red-brown in and dejecta. 
below the cell as far as the margin below the apex, the veins in the marginal area on both sides bordered with 
light; tlie end of the median vein is white-striped, at the cell-end there is a black small luna below bordered 
with white, behind it a row of vein dots. Hindwing brownish. Eastern and Central States. 
178. Genus: Mypot*ooiia Hmps. 
The genus contains but one slender species distinguished from the preceding genus by the thorax being 
coarsely haired without tufts. 
H. rufostriga Pack. (= punctivena Sm., rufostrigata Hmps.) (46 d). Forewing ochreous-reddish with rutostriga. 
whitish veins strewn with black, and a black faded longitudinal stripe from the centre of the median vein to 
the margin; instead of the postmedian line a double row of dots on the veins. Hindwing yellowish greyish- 
brown. From Labrador and Canada to Colorado.
