NASCUS. By Dr. M. Deattdt. 



caepio. N, caepio H.-Schdff. (170 b). A smaller species, above dark brown, in the disc somewhat lighter, 



yellowish, «ith 4 j?ellow apical streaks and 4 discal spots. Hindwing above unmarked, only beneath spotted black. 

 Honduras to Colombia. 



mermcros. N. mermeros Mah. is much smaller, otherwise very similar. Above lighter brown mth the discal 



spots much more crowded together, so that the impression of a single large spot is created. The hindwing is 

 less extended at the anal angle. The antennal club is much shorter, the point bent down shorter than in caepio. 

 BrazU. 



giants. N. glarus Mab. is dark brown, in the proximal half of the fore wing obliquely cut off and in the disc 



of the hind^^ing dimly reddish-yellow. The 4 discal spots form an oblique row on the border between the 2 

 colours; m the apex of the forewing there are only 2 hyaline spots. On the hindwing the usual cell-spot and 

 the bent row of 5 spots behind it. From the Lower Amazon. 



advena. N. advena Mah. very much resembles glarus and is above likewise rusty brown, but it has 3 small 



apical spots; in the disc there are 4 golden yellow hyaline spots only separated by the veins, the one situate 

 below the cell being gnawed out inside and outside. The hindwings are darker. The antennae exhibit a yellow 

 ring before the club. Costa Rica to Colombia. 



gildo. N. gildo Mab. is above dark bro^^ai \^dth a remarkably broad costal fold; of the 4 yellow discal hyaline 



spots the one situate in the cell is gnawed out towards the costa; the spots are besides small, separated far 

 from each other. Hindwing as in the preceding. Coary. 



gimla. N. gizala MoscJil. (= cephisus Hew., evathlus Mab.) (170 a). The brown forewing is haired yellow 



at the base ; at the apex there are 4 apical dots, the disc is traversed by the 4 hyaline spots in the shape of an 



\ oblique band from the costal margin to the proximal angle, the lowest being bent somewhat inwards. 



Hindwing in the middle slightly angled, unmarked. Beneath the proximal half of the wing is unmarked dull 

 yellow. The $ is somewhat larger and lighter and more extensively yellow. Panama, Colombia. 



cephise. N. cephise H.-Schdff. (170 b) is above lighter ferruginous brown than caepio, the yellow discal spots 



somewhat more of the shape of an oblique band owing to the lowest spot being enlarged : the 3 small apical 

 spots form a row inwards convex, in caepio distally. The hindwmgs are unmarked, the fringes somewhat speckled. 

 Beneath on the forewing, the proximal margin is whitish, and on the hindwing the postmedian band of spots 

 exhibits two distinct yellowish spots at the anal angle. The 9 has broader wings and white instead of yellow 

 orima. spots. BrazO. — orima Schs. I daresay belongs hereto as a form with somewhat more markings: on the forewing 

 there is m the discal spot in the angle between the radial and median vein a small brown dot, and the hindwing 

 shows two darker transverse lines. Petropolis. 



hroteas. N. broteas Cr. (169 f) is above blackish-brown with 4 apical streaks and a white oblique band and 



a punctiform spot in the middle before it. Hindwing in the middle angled, above in the basal part with ochreous- 

 yellow hair, beneath in the proximal half light yello^v, at the costal margin witli the beginning of a band of black 

 spots. Of this species only $2 are known, of cous only ^^, so that both may belong together. Guiana, Brazil.

cehrenus. 



nrita. 



N. annulicornis Mschlr. (170 a) is smaller than broteas, above rusty brown, towards the base lighter, on 

 the hindwing very extensive. On the forewing there are 5 small apical spots in a straight line, beside 4 small 

 black dots. The middle is traversed by an oblique band of 4 white hyaline spots from the costal margin to the 

 inner-marginal vem; the two uppermost are the largest and on both sides gnawed out. The middle of the hind- 

 wing is traversed by 2 straight rows of faded black spots. The under surface is lighter, otherwise marked the 

 same, but on the hindwmg the 2 macular bands are coherent. Here likewise only $ $ seem to be known. Nicaragua 

 to Brazil. 



N. cebrenus Cr. (170 b) is known only from the figure. Above blackish-brown, towards the base 

 yellowish. On the forevong there are 3 small apical spots and a straight band of white hj'aline spots in the 

 middle, the thi'ee upper ones of which are coherent, whUst the two smaller lower ones are separated from each 

 other; m the angle between the median and radial vein there is another small spot. The hindwings are darker 

 brown, unmarked, the bodj' is covered with ferruginous brown hair. The position of the insect described from 

 Surinam remains doubtful. 



N. orita Schs. is known to us only from the description and seems to be most closely allied to zopyrus 

 (168 a) placed hj Mabille to the genus Nascus as a synonym to his hydarnes. Wings dark brown mtli light 

 olive-brown hair at the base. The fore\\dng shows 3 small white apical spots and a quadripartite discal band, 

 the uppermost spot of which is yellowish at the costal margin, whilst the others are white, transparent. Hind- 

 wmg extended into a short, obtuse, bent, small taU with white-speckled fringes. Beneath the discal spots are 

 all white, the apex of the forewing is strewn a little with white; the hmdwing shows 2 indistinct transverse 

 shades, the distal one being outside analwards spotted whitish. Expanse of wings: 38 mm. Described from 

 Peru.
