UTETHEISA. By Dr. A. Seitz. 
(= suffusa Smith) (38 g) differs from the preceding by the hindwings being white, not golden yellow. Here we 
may also notice a reduction of the black stripes of the forewing (= triangularis Smith), to such a degree that 
fulvicosta. only the costa is yet narrowly bordered dark, and this form, fulvicosta Clem. (= duplicata Neum. and Dyar) 
(38 g) is even the form described first, so that, in case these forms should be separated specifically (according 
to Hampson, contrary to Dyar), fulvicosta forms the name of the species. — Larva black with a lustrous black 
head, blue tubercles, on which there are few, short, though stiff dark hairs. Across the dorsum a yellowish, 
interrupted median line being tinged reddish on the rings, beside it feebler, slight subdorsal lines. Lateral stripe 
broad yellow, in some places broken up into spots. On Pyrus and Prunus, according to Riley also on oak-trees. 
The butterflies are distributed over the Atlantic States of North America, being common in Texas, growing 
rarer to the north. In the south they occur already early in May. 
lecontei. H. lecontei Bsd. (— leucomelas H.-Schaff.) (38 g). Typical specimens have an entirely white ground¬ 
colour; the forewings are margined with black and exhibit a dark oblicpie band from the apex towards the 
distal part of the proximal margin, a white oval in the apex and a small cell-end band from the costa. — In 
militaris. militaris Harr. (= harrisii Dyar) the oblique band of the forewing is once or twice interrupted, and the 
confinis. ground-colour in the is sometimes tinted creamy-yellow. — confitlis Wkr. has a complete oblique band, but 
smithii. the marginal bands of the forewings are reduced. •— smithii Dyar exhibits the dark stripes interrupted as well 
dyari. as of an irregular course. — In dyari Merrick there are no dark markings at all; the insect is unicolorously 
bone-yellow, so that it may only form a transition to the following species, which is regarded by some (Dyar, 
Holland) to be merely another form of lecontei. ■ — Larva black with a bright yellow dorsal and a similar lateral 
line (Strecker); it lives on Triosteum perfoliatum, and wherever this is growing abundantly, the butterflies 
are often met with in big crowds at the end of May and beginning of June. Atlantic States of the Union, 
from New England to Georgia, and to the west as far as the Mississippi. 
vestalis. H. vestalis Pack. Size somewhat smaller than that of the form dyari of lecontei, which it also resembles, 
though it is altogether white, not bone-yellow, all the wings being void of markings, except the costa and border 
being faintly bordered dark at most. Atlantic States. Presumably only a form of lecontei. 
confusa. H. confusa Lyman (38 h). In this species the stripes of the forewings form a whole net leaving the 
ground-colour free only in 5 larger and some smaller spots. Hindwings of a pure white. — Larva when grown 
up black with yellow lines in the middle and at the sides of the dorsum; lateral rows of partly obsolete light 
lymani. dots. On Cynoglossum officinale. — In the form lyniani Dyar the markings are reduced and more interrupted; 
otherwise the form seems to be constant. In the northern (New England) States. 
contigua. H. contigua Wkr. (38 h) is entirely white, the margins of the forewings black; a black, postmedian, 
lumbonige- transverse band sending forth a branch below the middle of the margin. — In the form lumbonigera Dyar the 
ra ‘ distal band is absent. Atlantic States; in July. 
10. Genus: Utetlieisa Hbn. 
The forewings more stretched, narrower and longer, the costa more curved, the margin shorter. A 
uu&iiiopolitical genus found not only in all the 5 continents, but also in numerous islands. As to further particulars 
see Vol. II, p. 73, and Vol. X, p. 260. America has 3 species. 
omatrix. U. ornatrix L. (38 h). White, forewing tinged rosy with small red spots along the costal and distal 
margins, before and between which there are few black dots. Hindwing in the distal part with black, confluent 
spots, which in the <$ are more confined to the marginal area, while in the $ they often occupy more than half 
siretchi. the wing. - — stretchi Btlr. (= pura Btlr.) has more numerous, small, black dots on the forewing, which also 
penetrate the disc in rows, the hindwing being tinted rosy-red as far as the median. From South Florida and 
the Antilles through Mexico, Central and the whole of South America as far as Argentina, in some districts 
very common, flying almost throughout the year. 
betla. U. bella L. (38 h). On the forewing orange-red transverse bands alternate with white ones being 
intermedia, dotted black; hindwings purple-pink, irregularly margined with black. — In the ab. intermedia Btlr. the under 
surface being otherwise red with black markings, is also spotted white, and on the hindwing above there is 
hybrida. an interrupted spot before the marginal band. — ab. hybrida Btlr. has the hindwings above in the distal half 
terminalis. more broadly margined dark, and much more black on them, whereas in ab. terminalis Neum. and Dyar the 
marking in the disc of the forewing is lighter, and the ground-colour of the hindwing white instead of purple or 
pink. — In the Atlantic States often common, to the south as far as Mexico and Yucatan, flying in autumn 
venusta. and sometimes till November. -—- In the Antilles there occurs a local form, venusta Dalm. (= speciosa Wkr.)\ 
instead of the orange bands on the forewings, it is coloured crimson or miniate, and the black marginal band 
of the hindwing is much narrower. — The larva lives on Myrica gale. It is black, speckled yellow and 
white, across the dorsum darker, with a lustrous red-brown head and leather-coloined ring-indentations. Under¬ 
side leather-coloured; hairing dark, thin, bristly. The larvae of the Antilles-form venusta are coloured orange 
with black transverse bands (Packard).
