instead of the small dark marginal spots there is only a fine line; fringes speckled white. Hindwing light reddish, 
at the margin dark red. From the Bahamas (Abaco). Expanse of wings: 30 mm. 
T. lycaon Drc. (1 d) likewise belongs near to the preceding and is easily recognizable by the white lycaon. 
basal spot of the forewing; the ring-macula is surrounded by a large U-shaped spot; the hindwing is light yellow, 
broadly bordered with a rust-brown tint. Head and collar white; thorax reddish-brown, abdomen yellow with 
black dorsal tufts. This species originates from Ecuador (Sarayacu) and has an expanse of wings of 29 mm. 
T. sabulosa Fldr. (= sevorsa Grt., noctuiformis Msclnlr.) (1 b) is a very variable species, whitish, densely sdbulosa. 
dusted with grey, with 2 somewhat dentate transverse stripes and darker maculae. Abdomen and hindwing 
yellow, the latter with a black marginal area. By a reduction of the grey scales the whole discal area may turn 
white; I denominate this form: albidisca form. nov. (1 a), or only a spot behind the reniform macula: albiplaga albidisca. 
form. nov. (1 a). In the two latter forms also the thorax and the basal area of the forewing grows more or less all)l P laf J a - 
white. From Mexico and Guatemala, known also from Porto Rico. 
4. Genus: l*sesi«lalypia H. Edw. 
Distinguished from the following genus Alypia chiefly by the long, triangular, laterally knobbed frontal 
projection. The short palpi show in front, the tibiae are only scaled. No difference in the neuration. Only 
2 species from North America were described. 
P. crotchi H.-Ediv. (5a) is black with a brownish reflection; base of palpi, collar and anal tuft are crotchi. 
orange. The forewing shows a narrow, yellowish-white transverse band ending pointed at the proximal margin; 
as far as to it the costal margin is of the same colour; fringes of the hindwing and of the apex of the 
forewing white. — In the form atrata H. Edw. the transverse band is absent. The species was described from atrata. 
California. Expanse of wings: 26 mm. 
P. geronimo Barnes from Arizona has the transverse band parted into 2 quadrangular spots at geronimo. 
the apical third of the costal margin and near the posterior angle; the former shows inside silvery blue scales, 
and partly also the veins; the collar, palpi and anus are black, the hairing of the legs, however, and a hair-tuft 
beneath at the base of the wings are orange. Flying in July and August.

5. Genus: Alypia Hhn. 
Not quite a dozen of small, black, rather similar species decorated with yellowish spots and silvery 
blue scales. They are distinguished by their squat, strong structure, and have very long-haired, ascending 
palpi; also the tibiae and base of abdomen are covered with long and coarse hair. Thereby and by the plainly 
coniform frontal projection they are distinguished from the preceding genus. The neuration does not show 
any difference except the upper radial on the forewing rising from below the upper cell-angle. All the forms 
are found in North America, some descending as far as Mexico. 
A. mac-cullochi Kirby (1 b). In the A the forewing is expanded from the base to behind the middle 
and shows beneath a deepened, transversely ribbed, narrow, skinny stripe. The forewing shows 3 yellow spots, 
the hindwing two white spots. Spots on the collar, stripes on the shoulder-covers and small dorsal spots are 
yellow, the anterior and middle tibiae are orange. — The form lorquinii Grt. <£■ R. has an elliptic spot instead lorquinii. 
of the bent postmedian band. — In similis Stretch the spots of the hindwings are also yellow, those in ab. con- similis. 
juncta H. Edw. more or less confluent. Canada, California. Expanse of wings: A 30, $ 36 mm. conjuncta. 
A. disparata H. Edw. (= gracilenta Graef, desperata Ky.) (lb). The bare, ribbed stripe described disparata. 
in the A °f Ike preceding species is here only present in the distal half of the costal margin; the forewing is 
much more stretched and only shows 2 yellow spots. Widely distributed from the United States to Mexico. 
A. brannani Stretch is very much like disparata in all its parts, but somewhat smaller, and the brcmnani. 
spots of the forewings are white instead of yellow. California. Expanse of wings: 34 mm. 
A. octomaculata F. (= bimaculata Gmel., quadriguttalis Hbn.) (lb) is almost exactly coloured and 
marked like disparata, but it has much shorter and broader wings, and the is without the secondary distinction 
at the costal margin as in all the following species. — alboniaculata Stoll (= matuta H. Edw. has a small and 
round white basal spot of the hindwing. — In wittfeldi H. Edw. the middle yellow spot of the forewing extends 
almost to the proximal margin. Widely distributed in North America. -— The larva has an orange head, neck- 
shield, anal valve and dorsal bands, showing on black tubercles one long white hair each. It lives on the vine, 
attains its adult state in July and builds a glutinous earthen habitation in which it hibernates. 
A. dipsaci Grt. resembles the preceding by the distribution of the spots, but the spots of the hindwings dipsaci 
are yellow, not white, and the postmedian spot of the forewing is considerably larger. Described from California. 
Expanse of wings: 32 mm.
