less encircled with white, filled with pink and yellowish brown shadows. The basal spot is the largest, extending 
to the exterior line which it joins inside. The upward prolongation is filled with pink and white, the lower one 
by a double yellowish spot. A brown quadrangular spot at the middle of the inner margin is edged with white 
above and outside. The spot at the anal angle is oval. Apical spot oval, filled with pink, edged somewhat white. 
The fifth spot at the costal margin near the apical spot is round, filled with yellowish brown, edged with pinkish 
white. Hindwing dark brown with a light median line. $ 40 mm. Arizona. Presumably only 1 specimen known. 
Eu. tema Strecker. Body brown, patagia greyish white. Forewing, base and apical spot greyish white. 
The basal spot is very angular and extends to the inner margin. A darker band behind it is traversed by dark 
brown lines. Median area paler, behind it follows a similar dark band with lines. Reniform macula indistinct. 
Marginal area paler grey. The pale apical spot is edged with dark outside. Hindwing light grey, darker at the 
margin. 42 mm. North-Western States. According to Barnes & McDttnnough, tema is identical with the 
following species. 
Eu. semicircularis Grt. is compared by the author with Cym. improvisa Edw. from which it differs in 
the absence of the yellowish green spots at the pink marking. Wings broad. Forewing with a creamy white, 
black-edged spot at the base, with a point in the submedian fold. A broad interior dark band behind it contains 
3 or 4 black lines. Median area dark grey, the rest of the wing whitish grey. Behind the middle another in¬ 
distinct dark band with 2 or 3 lines, nearing the first band at the inner margin. Ring-macula and reniform 
macula small, rather indistinct, close together. Submarginal line composed of black lunae, as in lorata where, 
however, it is not mentioned in the description. Hindwing yellowish grey, 40 mm. North-Western States. - 
griseor Barnes. Patagia dark, not light grey as in the nomenclatural form. Forewing slightly tinged with smoky 
grey, the lines more indistinct. The white basal spot and the apical spot are less prominent, especially indistinct 
is the former. Hindwing darker with a broad dark brown margin. 1 40 mm. Nevada. 
4. Genus: Pseuclothyatira Grt. 
Palpi thick, porrect. Forewing bent at the costal margin at the base, with a short dent of scales at the 
anal angle. Vein 5 from the middle of the cross-vein, 6 from the middle of the areole, 7 -\- 8 and 9 from its apex, 
10 from its anterior edge. Veins 3 and 4 of hindwing slightly separated, 5 above the cell-angle, 6 from the upper 
angle, 7 a little back, 8 nearing 7 as far as behind the cell-end. Abdomen of laterally with a hair-pencil. Type: 
cymatophoroides Gn. 
Ps. cymatophoroides Gn. (172 k). Thorax dark red-brown, abdomen lighter, with black tufts. Forewing 
still lighter. Interior line threefold, dentate, black. Rusty brown before it in the middle of the wing, black 
at the base. A rusty brown dot in the middle of the cell and at the lower cell-angle. Exterior line threefold, 
black, extra-angular below the costal margin, then almost extinct, obliquely inward. Submarginal line of black 
sagittal spots. A divided dark brown spot before it at the costal margin, a larger spot before it at the anal margin, 
edged with white inside. Hindwing reddish brown. 35—42 mm. Atlantic States, Nova Scotia as far as New 
Mexico. 
Ps. expultrix Grt. (172 k). Thorax and forewing red-brown, greyer in the marginal area. Interior line 
black, of a very irregular course, edged with white inside, two less distinct parallel lines behind it. The ring- 
macula is a rusty brown dot, the reniform macula narrow, black or rusty brown at its lower end, the rest finely 
edged with brown. An indistinct dark median line extends across the reniform macula. Exterior line black, 
double, rather indistinct, far outward close below the costal margin, then obliquely inward in large dents, the 
interior branch more distinct above the inner margin, edged with white. The black submarginal spots are intense. 
Anal angle rusty brown. Hindwing somewhat lighter than forewing. 38—42 mm. Canada to Texas. 
5. Genus: Cymatophora Tr. 
All the necessary details about this genus have already been given in Vol. II, p. 326, under the name 
of Palimpsestis Hbn. The 14 species of the latter are opposed by only 5 species in the American Fauna, 3 of 
which occur in North America. It is not sure whether the two South American species belong to this genus. 
C. improvisa Edw. is sometimes regarded to be identical with Cym. tearlei H.-Edtv. (172 k); it is also 
vdrv similar to Euth. semicircularis, but the interior black band is undulate in improvisa and incurved in the 
submedian fold, not uniformly bent. Moreover, the ring-macula is indicated in improvisa , the apical streak 
is not undulate, the basal spot extends to the inner margin, improvisa is also similar to the following fasciata , 
but the green basal area of improvisa. is not so extensive as in fasciata and distinctly apple-green. In the marginal 
area only the apical spot and the submarginal line are green. The exterior line is much more oblique at the 
costal margin in improvisa than in fasciata. ? mm. North-Western States. 
C. fasciata Barnes & McDunn. Body brown, only the patagia grey. Forewing light violettish brown, 
with a slight whitish green at the base and at the distal margin, the broad median band of the same colour. The 
basal area is bordered by a curved line which is bent inward in the submedian fold, besides with 3 parallel dark 
lines before it. Median area with a small round black spot in the cell, a dark undulate median line behind it.
