ROTHSCHILDIA. By Dr. M. Draudt. 
ochracea. habitats, in Mexico, there also occur ochreous specimens: — ochracea f. n. In Mexico another very conspicuous 
prionidia. form is found: - prionidia /. n. (134 a) of less than half the size, with a more falcate apex of the wing, light 
olive brownish ground-colour, the hyaline spots being proximally much deeper concave, distally extending 
far beyond the postmedian line, the very narrow light pink subterminal band almost reaching to the costal 
margin. I cannot decide whether it is a special condition-form; perhaps it is only a stunted form. Several 
specimens originate from the capital of Mexico, taken in June and August, without any transition-forms to 
triloba, the normal form. — In triloba Rothsch., described from Costa Rica, the hyaline spots of both wings are proxi¬ 
mally deeply indented, the lower side is twice as long as the upper, also on the hindwing, the point projects 
meridana. beyond the postmedian line. meridana Rothsch. resembles the following form, but beneath the abdomen is 
less white; the hyaline spot of the forewing is proximally 1 / 3 longer than costally, often concave; the hyaline 
spot of the hindwing is proximally shorter than costally, here just as long or longer than distally. Merida 
bogotana. (Venezuela). bogotana Rothsch. is in the male brighter reddish-yellow, the abdomen beneath all white, the 
triangular hyaline spot on the forewing with straight sides, proximally and distally equally long, costally only 
half as long, touching the black postmedian line as on the hindwing and far remote from the anterior transverse 
line; the pinkish-grev band behind it is less broad than in cauca. The hyaline spot on the hindwing is distally 
rounded, the straight proximal side longer than the costal one; submarginal spots all equally large; the upper 
cauca. ones reddish. Colombia (Bogota). - cauca Rothsch., from the Cauca Valley, is darker chocolate brown, with 
small hyaline spots, those on the forewing proximally straight, far remote from the anterior transverse line, 
and neither reaching the posterior line which is not so strongly dentate as in the nomenclatural type, between 
2 and 3 not so deeply indented, finer, and more remote from the margin; the pinkish-grey band behind it is 
broader, but not so prominent as in orizaba ; the subapical crescent is filled with red, the white line before it 
straight. On the. hyaline spot of the hindwing the anterior and posterior sides are equally long, the proximal 
side rounded and short; the upper submarginal spots are very large, reddish. Beneath the costal margin of the 
equatorialis. forewing is not dusted with grey. equatorialis Rothsch. is in the male bright tan-coloured brown, the $ ochreous, 
in the $ the subterminal area is also ochreous, in the disc reddish blackish-brown, dusted with white; post¬ 
median line strongly dentate, the pinkish-grey band behind it broader than in Mexican specimens, the white 
dusting less dense; the subapical crescent is filled with red, the white line before it straight; hyaline spot 
proximally rounded, rarely straight, on the hindwing small, proximally very round, submarginal line better 
peruviana, marked than in the Mexicans. From Western Ecuador. — peruviana Rothsch. has a still more dentate post- 
median line and a larger hyaline spot which is basally incurved or straight. Beneath all the submarginal spots 
of the hindwing are red. Carabaya (South-Eastern Peru). In the larva all the tubercles are equally large, 
conical; green, with a yellow sublateral stripe, anal plate and prolegs also green, edged with black; it lives on 
foliage trees such as cherries, ash-trees etc. The natives are reported to wear a necklet on which cocoons are 
threaded in order to prevent the whiskers from growing. 
prionia. R. priorsia Rothsch. (103 b) is allied to jorulla, but different in the genital organs; postmedian line in 
both wings strongly dentate, the white portion and its red distal border broad; the pinkish grey band distally 
to it is extended towards the costa as far as the apical spot which is brighter pink; the costal angle of the 
hyaline spot on the fore wing is rounded, the proximal edge oblique; the hyaline spot on the hindwing is large, 
more than twice as long as broad, the basal end in front obliquely cut off, behind rounded; the pinkish-grey 
band is narrow, dentate, the posterior submarginal spots small, only the last being large. The species also 
resembles lebeau, but the postmedian line is more dentate, both the wings narrower, the hyaline spot on the 
hindwing much longer, the pinkish-grey band more dentate. North-Eastern Brazil, Venezuela. 
jorulla. R. jorulla Westw. (== splendida Clem., cinctus Tepp.) (101 c) is relatively small and slim, in the median 
area dark olive brown, the antemedian line between veins 1 and 2 mostly with a very distinct convexity towards 
the margin; posterior transverse line very strongly dentate, the white and red portions broad, the pinkish- 
grey band narrow, extending to veins 4 or 5; the hyaline spot of the hindwing is proximally either concave, 
straight or even convex, the anal submarginal spot mostly very large. This is the chiefly Eastern Mexican form 
which, however, was also found in Arizona. In Western Mexico (Guerrero, Colima) light cinnamon-reddish 
guerreronis. specimens predominate: - guerrerorsis j.n. (134c); here the white portion of the postmedian line is mostly 
inca. extraordinarily broad, with larger hyaline spots. inca Rothsch. shows the pinkish-grey subterminal band 
extended farther anteriorly, on the forewing more deeply dentate, on the hindwing posteriorly much less 
extensive than in the nomenclatural type, more sharply outlined, distinctly dentate; postmedian line finer, 
also ifs reddish-yellow distal border, especially towards the costal margin; posterior submarginal spots on the 
joruUoides. hindwing larger than in jorulla. From South-Eastern Peru. — jorulloides Dogn. exactly resembles jorulla. 
the ground-colour is just as olive brew n: distinguished by the straight postmedian line being only moderately wavy 
and not so strongly and uniformly notched as jorulla: the white line bordering distally on the pink apical spot, 
is likewise straight. From Ecuador (Loja). The larva shows before its last moult yellow, at last red tubercles, 
the adult larva is quite smooth, green, with lateral blue and white oblique stripes, it lives on oaks, cherries, 
ailanthus etc., pupating in a cocoon similar to that of orizaba, though smaller and more regular. 
amocna. R. amoena Jord. is similar to jorulloides and maurus, with shorter and broader wings, postmedian line 
somewhat less strongly dentate than in maurus , in front and behind curved somewhat more basad; the
