P. portlandia Edw. (= descherei Neum.) which was formerly regarded as a melanotic form of rim< sa porllandia. 
is considered to be a distinct species now. Shape and marking the same, but the disc of the forewing is 
not white but mouse-coloured, the brown parts are almost black. Hindwing dingy white with a broad smoky 
grey marginal band and a large dark anal spot. Somewhat larger on an average. Alaska to California. 
131. Genus: Calomatlietes Dyar. 
Shape and exterior very similar to that of the palaeartic genus Pterostoma ; $ antennae pectinated long 
to the tips. Distal margin of forewing dentate, a broad scale-dent in the middle of the inner margin and 
one before the anal angle; the uppermost and lowest subcostal branches are free, the 3 middle ones stalked. 
The obliquely rising palpi are densely scaled below, but not so long as in Pterostoma. Only 1 species. 
Type of genus: G. halmaphylla Dyar. 
C. halmaphylla Dyar (155 a). Forewing whitish strewn with brownish, somewhat more yellowish tiahna- 
in the cell and behind it, dusted with violettish-grey in the basal and marginal areas, with fine double vh 
dentate transverse lines, with black and wiiite vein-dots behind the exterior line; discal fold finely striped 
black, double in the basal half of the cell, 3 black dots at the cell-end; instead of the undulate line there 
are small purple blackish spots bordered with white inwardly; veins of marginal area striped black. Hind¬ 
wing brownish, fringe lighter. Mexico. 
132. Genus: Goacampa Schs. 
The long antennae are shortly pectinated in the <J, serrate in the $, the very short palpi are porrect. 
Eorewing long and narrow, with a long areole; vein 6 arises before the centre of it, the 4 lowest subcostal 
branches from the end of the areole. Vein 5 of the hindwing is absent here and in all the following genera, and 
6 arises on a rather long stalk with 7, and 8 close from the cell-end. Only 1 extremely variable species. 
Type of genus: G. variabilis Schs. 
G. variabilis Schs. (155 a). The nomenclatural type has whitish-grey forewings with a silky gloss, with variabilis. 
a darkened blackish basal area, notched single black transverse lines, the posterior one of which fades away 
more or less towards the costal margin, with a large reniform macula surrounded by black; the subterminal 
line represented by black internerval wedges behind which the ground is somewhat lighter whitish, besides 
some shorter wedges before the margin; fringe spekled white on the ends of the veins. Hindwing white, dark¬ 
ened black before the snow-white fringe, wdth a broader wedged area before the anal angle. This form 
has an expanse of 43—46 mm and was described from Oaxaca in Mexico, but it occurs also in Colima. - 
Another form of only half its size (expanse of wings: 35 mm) has a much darker forewing coarsely strewn 
with black, without the silky gloss, with less distinct markings, I denominate: tehuacana /. nov. (155 a), from tehuacana. 
Tehuacan in the State of Puebla; the hindwings are neither purely white here, but smoky brownish. — f. dimi- diminuta. 
nuta /. n. (155 a) is a still much smaller form with a wing-span of 25 mm, so that there is no resemblance 
whatever between this dwarf and the type. Fore wing uniformly grey, the marking almost extinct. Hind- 
wing wdiiter than in tehuacana. This is the western coast form from Guerrero. Nevertheless all three are most 
probably one species, for all of them exhibit the same aberration, since the submedian fold may be sometimes 
darkened black from the base to the margin: — ab. nov. striata (155 a); the space behind the cell may occasion- striata. 
ally also be black as far as the margin as in the figured specimen; the reniform macula of other specimens 
is entirely filled with black, but it is of no use denominating all these forms which may also be combined. 
133. Genus: Pilodonta Dogn. 
This genus contains but one species so far; it is allied to the preceding genus and differs in a longer 
and stronger middle joint of the palpus, a much longer abdomen and peculiar long and fine hair of the cell 
on the forewing and of the costal margin on the hindwing. Veins 3 and 4 of hinclwing on a short stalk. 
Type of genus: P. subcrinita Dogn. 
P. subcrinita Dogn. has quite monotonously ash-grey forewings strewn slightly darker, with whitish subcrinita. 
strewing at the base and along the costal margin; only a small dot encircled by white is at the cell-end. 
Hindwing somewhat lighter. Expanse of wings: 57 mm. French Guiana.
