G. rabidan sp. n. (184 b). Small, hindwing black; forewing dark grey, the basal two thirds shaded rabidan. 
with brownish, the marginal third with coarse black reticular markings, the basal part only slightly marked 
black. Expanse ot wings: 20 mm. Only 1 no habitat mentioned, type in the U. S. National Museum. 
G. Cornelia Neum. A Dyar (= caerulea Dalla Torre) (184 b). The subsequent species exhibit a more cornelia. 
triangular shape of the forewing with but very insignificant markings. Body and wings white, slightly tinged 
brownish behind the cell, a rather large round punctiform spot at the cell-end; small strigiform spots at the 
inner margin and on the hindwing. Colorado. 
G. theodori Dyar. White, the thorax slightly mixed with light grey; basal half of forewing without mark- theodori. 
ings, only a few black dots at the costal and inner margins, with large purple grey spots behind the cell, tra¬ 
versed by the white veins; distal half of hindwing striated light purple grey. - kunzei Dyar is somewhat smaller, Icunzei. 
the postmedian spots are inclined to be confluent. Arizona. 
G. durangona Schs. (184 b) differs from theodori in the large spots in the postmedian area being replaced durangona. 
by but scanty small strigiform spots; a few reddish striae at the inner margin. Colorado. 
G. carla Dyar is the same, but the grey markings in the distal area are more reticulated. It is doubtful carta. 
whether it is a separate species. South California. 
G. lucretia B. A McD. is larger; forewing white with a dark macular band from the centre of the inner lucretia. 
margin obliquely to the upper cell-angle. Texas. 
G. albicosta Schs. (184 c). Mouse-coloured, forewing shaded reddish at the base and apically, the costal albicosta. 
margin rather broadly greyish white, the wing covered with indistinct dark striae. Hindwing grey. The 
frenulum is a stout short thorn, finely pointed. Costa Rica. 
G. pallidicosfa Schs. (184 c) is smaller than albicosta, hindwing white with small grey marginal spots pallidicosta. 
and fringe. The <$ frenulum is a delicate fine short thorn. Brazil. 
G. nais Drc. (= naida Dyar, albipuncta Schs.) (182 f). Grey with a reddish tint and a slightly darker nais. 
discal cloud on the forewing and a silvery white marginal stripe at the inner margin from the base to the middle; 
indistinct darker striae and a white discal dot are occasionally traceable. Hindwing of $ whitish grey, of $ 
somewhat darker. The <$ without a frenulum. Mexico, Guatemala, and Costa Rica. 
G. anna Dyar (184 c) resembles nais, but it is darker grey without the reddish brown tint. $ likewise anna. 
without the frenulum. Florida. 
G. lotta B. & McD. (184 c). Like anna, but the fringe more spotted; a white discal spot is usually lotta. 
absent, basal area slightly darkened with brown. Hindwing dark smoky brown, slightly reticulated, fringe 
speckled. Arizona and Colorado. 
G. neceros Dyar (184 c). Dark reddish brown with a dark oblique shadow through the centre of the neceros. 
wing. Hindwing blackish brown. like the preceding species without a frenulum. Panama. 
G. marga B. A McD. (184 c). Dark grey, somewhat dustedly strewn with a narrow white discal streak; marga. 
the <$ has neither a frenulum nor a costal-marginal reverted fold. One specimen lacks the upper branch of the 
discal vein on the hindwing. South California. 
G. ethela Neum. A Dyar (184 d). Light grey, spotted darker; a white discal dot at the cell-end and ethela. 
a black one below it. £ without the frenulum and the costal-marginal reverted fold. The larva lives in Purshia 
tridentata. Colorado, Utah, and Nevada. 
18. Genus: Psychogena Ms. 
The genus has the same neuration as Givira, but the veins 6 and 7 on the hindwing are on a long stalk, 
and 7 and 8 are connected by a bar. Hindwing of $ sharply triangular. 
Type: P. miranda Schs. 
P. miranda Schs. (184 d). Body shaggily clad, abdomen with lateral black scale-tufts. Forewing reddish miranda. 
brown, interruptedly reticulated, a black spot basally, a triangular one at the inner margin, and a large round 
one at the cell-end; the apex is broad, the distal margin narrow black. Hindwing black. Only the type from 
Costa Rica is known. 
P. duplex Schs. (184 d) has monotonously blackish brown forewings. Hindwing whitish, diaphanous, duplex. 
black along the inner margin. Only 1 type from French Guiana is known.
