this name and confounded them with others. Thus quite a number of forms from the most various districts, 
from Java to the Philippines and from Indo-China to North Australia, have been collected, either as synonyma, 
or as side-forms or subordinate forms of baulus, many of which were regarded as separate species, certainly 
often also correctly so. The typical baulus Bsd. (29 i) is, according to Swinhoe, said to be identical with mundi- 
picta Wkr., but also with herklotsi, which seems to be quite impossible, because mundipicta is quite certainly 
not identical with herklotsi from which it is very considerably distinguished already by the shape of the wings. 
If we take baulus to be identical with mundipicta Wkr., it would have to be a form allied to lacticinia in the 
colouring, which, however, shows the following differences: the proximal margin of the forewing is in its basal 
part not so broadly white. On the other hand there are white lines on or between the veins in the basal part 
of the forewing. The oblique band of the forewing is mostly in the middle somewhat wider. The tooth of the 
marginal band of the hindwing is more pointed and higher. The insect itself is mostly somewhat larger than 
lacticinia ; its range extends across the Sunda Islands and New Guinea to North Australia. — picata Btlr., descri¬ 
bed from Sumatra, Pagenstecher thinks to be identical with mundipicta. It is larger, the basal stripe in the 
submedian fold of the forewing is narrower, the border of the hindwing narrower and abruptly ending above 
at the 1st median veip, in order to reappear next to the anal angle as a narrow diffuse margin. -—- aluensis Btlr. 
(29 h) is almost exactly like a lacticinia, but the band of the forewing is traversed by thick black veins; Alu, 
Salomons. — illustris Sivinh., considered by Butler to be a form of aluensis and likewise brought from Alu, 
is according to Swinhoe entirely different from it. Thorax and abdomen are white, in some places tinted yellow, 
the former with 3 black longitudinal stripes, the* abdomen curled black, at the end ochreous. The basal part 
of the veins and the proximal margin of the forewing is streaked white, a white streak in the cell and a broader 
one below the cell, the latter streak extending into the lower part of the cliscal band. Of the spots forming this 
band the 1st and 3rd are the smallest, the 2nd being large, reniform, the 4th longer, the 5th the longest. Hind¬ 
wing as in baulus. — tertiana Meyr. (= latistriga Snell.) (29 i) is distinguished by a ray coming from the ray 
on the submedian fold extending into the band; from the Pacific Islands and the Malayan Islands to Australia. 
— simulatrix Wkr. (29 i), in which the basal ray is still stronger, differs from tertiana by the narrowness of the 
almost oval band of the forewing in tertiana', Celebes. — nisa Sivinh. is marked exactly as simulatrix, but it 
is smaller, the dark ground of the wings is deeper and the marking more distinct; from Sangir. -— nigrovena 
Sivinh. (29 i), likewise from Celebes, is larger, and on its hindwing it shows the lower median vein as well as 
the median itself and the submedian dark sooty. — pagenstecheri Pag. (30 h) is easily recognized by the white 
band of the forewing being quite smoothly margined, not notched and not pierced by black veins. Also the 
dark margin of the hindwing is proximally rather regularly and smoothly bordered; from Lombok. — fasciata 
Wkr., finally, from the same island, has quite dull brown, diaphanous scaling, and the white is very transparent ; 
the band of the forewing is notched at the margins and traversed by dark veins, so that almost the whole exterior 
of lacticinia appears; but like all the other members of the baulus- group this form also differs from all the lacti- 
cinia-iorms by the black abdomen being transversely curled. 
N. kinagananga Sivinh. frow New Britain on the forewing entirely resembles baulus, but at the base 
it has a white inner-marginal stripe. On the hindwing the dark marginal band is as broad as in lacticinia. 
N. dispar Druce somewhat resembles the species of the baulus- group, but it differs from them 
by the absence of all the vein-streaks in the dark proximal half of the forewing. The white discal band, however, 
is divided by the veins into 7 spots, in a similar way as in aluensis (29 h), but they are closer together. Rossel 
Island. The species is unknown to me in nature. 
N. dinawa B.-Bak. (30 a). I figure from the type. It is the only species of the genus, in which the 
discal spot of the forewing bends somewhat distally round at the costal margin. The white basal streak below 
the cell is quite straight, quite uniformly thickened and distally quite smoothly cut off. New Guinea. 
N. tenuifascia Snell. (29 i). Of this strange insect I only know the type in the Museum of Wiesbaden, 
which I figure here. The conspicuous marks are the almost quite orange thorax, the very hyaline wings and 
the small zigzag band on the forewing. From Lombok; discovered by Fruhstorfer near Sambalan in April, 
at an altitude of 4000 ft. 
N. mesolychna Meyr. is not compared with any species known, and there are no differences mentioned, 
for which reason the species is scarcely to be recognized. Forewing with whitish veins in the basal half and an 
undulate, whitish-brownish diffuse transverse patch, the hindwing white with an irregularly angled, brownish 
marginal band being narrow at the base and proximal margin, and with whitish fringes. New Guinea. 
N. sontica Sivinh. (30 a). Under this name there are 2 species not only exactly corresponding in the 
colouring and marking, but also entirely agreeing in the variation. The typical sontica only occurs in the Philip¬ 
pines, and it differs from radiata being coloured and marked quite the same by the much more pointed forewings
