mostly absent. — The larva is dark brown with a very broad yellow dorsal stripe, spotted reddish, and a light 
yellow postdorsal and lateral stripe. On Plantago and other low plants, easily bred with dandelion and lettuce. 
From the eggs of one and the same $ I obtained quite pale and very beautifully flesh-coloured imagines. Most 
anywhere in the United States from New York to California, beside nais and virgo the most common species 
of the genus; in July. 
A. proxima Guer. (= docta Wkr., mexicana Grt. & Rob., arizonensis Stretch, mormonica Neum.) 
(39 b). Both sexes quite different. dull yellowish-white, on the forewing some black triangles and quadrangles; 
proximal margin of the hindwing tinged rosy. ^ with much larger black spots separated by transverse and 
longitudinal bands; hindwings purple-red with large, often confluent marginal spots. — antheola Bsd. (= autho- 
lea Bsd.) is the name of specimens showing also in the $ the hindwings very much spotted black. — This is 
the southernmost species of the genus, distributed from California and the Rocky Mountains to the south through 
Mexico and Central America as far as Costa Rica, everywhere common. 
A. eervinoides StrecJc. A very small species, scarcely half the size of quenselii, reported to originate 
from Colorado. Thorax striped white, abdomen black with whitish sides. Forewings blackish-brown, the bands 
as usually whitish, hindwings white with short, small, dark stripes at the base, a blackish cell-end spot 
and blackish marginal band. Unknown to me. 
20. Genus: Parasemia Hbn. 
To the description of the genus in Vol. II, p. 81 we may add that the proboscis is stunted and the 
fore wing provided with an accessory cell. The genus only contains one species: plantaginis L., being also distri¬ 
buted over North America. 
P. plantaginis L. Of the palearctic forms, of which almost 30 are denominated up to this day, some 
also occur in North America and have partly been newly named there. — geonietrica Grt. (39b) has black 
hindwings; on the forewing the band above the proximal margin and the distal stripes, winch, though inter¬ 
rupted in the otherwise similar (Asiatic) form nyctitans (Vol. II, t. 16 e), are complete and confluent among 
each other. — petrosa Wkr. (39 b) shows a beautifully royal-yellow discal area in the $ hindwing, the basal 
part and marginal band being black; from California. — The species is common almost at all its habitats. As 
to the larva and its habits see Vol. II, p. 81. 
21. Genus: Ijeptarctfa Stretch. 
Only a single though very multiform species forms this genus. Proboscis stunted. Palpi straightly 
porrect, below bristly haired. $ antennae doubly combed, the pinnae something like in Parasemia. The forewing 
without an accessory cell, the discocellular on both wings angular. On the forewing not only the 1st, but-also 
the joint footstalk of the other subcostal veins rise before the cell-end. Remarkable is a vast sexual 
dimorphism. 
L. californiae Wkr. The typical specimens have grey, darker shaded forewings and orange-yellow 
hindwings, spotted dark near the margin, quite similar to the figured form lena Bsd. (39 b) from which, however, 
they differ by exhibiting besides some blackish markings also in the disc of the hindwing. The figured $ of 
lena originates from Colfax at the foot of the Sierra Nevada; as the $ belonging to it, a specimen was taken 
there on the same day (July 7th) with almost quite black hindwings only marked with a dull yellow postmedian 
band: this belongs to the form dimidiata Streck. (39 b) in which, however, also the hindwings may be quite 
black. — fulvofasciata Btlr. has likewise grey, dark shaded forewings; the yellow band in the hindwing, however, 
occupies almost the whole median area. — decia Bsd. (39 b) is marked almost like a brephos, but the ground¬ 
colour of the hindwings is a deep ruby-colour. — latifasciata Btlr. is the same, but the whole basal part of the 
hindwing is black. — boisduvalii Btlr. has quite similar hindwings marked orange and black, the forewings, 
however, show an irregular, whitish postmedian band. — stretchi Btlr. has similar forewings, but the hindwings 
are either quite black or they exhibit only very faint orange traces. Between these forms there also occur tran¬ 
sitions which, like some extremes, have received denominations which are, however, superfluous or are to be 
considered as synonyms, such as adnata Bsd., occidentaiis, wrightii, albifascia French. All the forms live — often 
occurring beside each other — in South California, where they are mostly common, flying in spring and summer. 
The forms mostly in request in the trade are, beside the type, dimidiata and lena. 
VI. Spilosomim. 
This group having been dealt with at large on p. 84 of Vol. II is characterized by the dorsal spots 
on the abdomen, which, however, also occur in many other Arctiid genera not belonging hereto. As we 
have emphasized in Vol. II, we do not acknowledge here a subfamily being systematically definable, as it was
