LYCHNUCHOIDES; NYCTUS; LYCHNUCHUS; TISIAS. By Dr. M. Deatot. 989 



182. Genus : liychiiiiclioides G. <fe S.' 



Antennae half as long as the costal margin. Cell of forewing very long and broad, ^/g of the length of 

 the costal margin ; hindwing at the anal angle lobate. Body stout, densely haired. The <£* has an angtdar stigma, 

 the upper part of which borders on the middle of the median, the lower on the lower median branch. Mabille 

 places here also hiarbas Cr. (= ozias Heio.) having been dealt with by us as Ancistrocampta on p. 879; (190 c). 



L. saptine G. & S. (190 c) is a large, blackish-brown species with a darker stigma, a broad, ochreous- saptine. 

 yellow, centrally hyaline transverse band; apex of hindwing yellow. Beneath the same, at the apex of the 

 forewing lilac-grey; hindwing red-brown clouded with grey. Larger than the very similar Ancistrocampta celsus 

 (171 a), the yellow band more irregular and the under surface different. Costa Eica, Panama. 



183. Genus: Xyctus Mob. 



Distinguished from Carystus by the long, horizontally porrect palpi; hindwing extended into a broad, 

 obtuse lobe; at the base of the inner-marginal fold there is a very long hair-tuft, and on the median veins are 

 also long, bent hairs partly extending beyond the margin of the wing and touching the abdomen. 



N. crinitus Mab. is a magnificent, velvety black species with a very broad orange oblique band crinitiAs. 

 exhibiting proximally 3 angular projections (subcostally, on the lower median vein and on the inner-marginal 

 vein), and being distally gnawed out at the lower cell-angle. Hindwing at the costal angle with an orange marginal 

 line and fringes ; the hair-pencil with a green reflection. Beneath the forewing is red-brown, the hindwing black 

 with brillant green veins. Expanse of wings: 52 mm. Brazil (Pebas). 



N. triangularis Kaye. Above dark brown, costal margin and the larger inner-marginal half lighter, iriangula- 

 A cellular spot and 4 postdiscal spots yellowish hyaline as well as 2 subapical dots. Hindwing with 3 small '^ 



spots in one line behind and below the cell. Collar golden yellow. Beneath very much lighter, especially the 

 base of the hindwing. Expanse of wings: 42 mm. Trinidad. 



184. Genus: Ijycliuuohus Hb 



n. 



Antennae long, the long club exhibits a slender, long apex. The terminal joint of the ascending palpi 

 is hidden. The anal angle of the hindwing is lobate, above it somewhat concave. The (J shows a bipartite stigma : 

 a stripe on the central part of the median between the branches, another one on the lower median vein. We 

 enumerate here only two species, the third: celsus F. (= clearchus Ploiz) (171 a) which is inserted here by 

 Mabille, we have already dealt with in Ancistrocampta on p. 879. As to the synonymy of the species and genera 

 there is still much uncertamty prevailing. Comp. also the genus LycJmucJioides (t. 190 c). 



L. olenus Hbn. (190 c) is of a plain blackish-brown with a very broad orange discal band which olemis. 

 is semi-diaphanous in its central part. Beneath the same, but the brown is slightly duller and more reddish. 

 Widely distributed in South America: Brazil, Colombia, Bolivia. 



L. pertica Plotz (190 c) resembles Ancistrocampta celsus (171 a), but the narrow discal band is white, peHica. 

 only^at the costal margin somewhat yellowish, and there are 3 white subapical punctiform spots. Beneath 

 somewhat duller brown, otherwise the same. Palpi beneath ochreous. South America, habitat not exactly 

 stated. 



185. Genus: Tisias G. &" S. 



Antennae longer than the cell of the forewing. Terminal joint of the palp short. Forewing long with 

 a bent eosta; hindwing at the anal angle lobate. Body robust. Middle tibiae with spines. Tlie cj has an angular 

 stigma on the middle of the median and the lower median branch, a longitudinal stripe below it, and a[ still 

 longer one on the submedian. 



T. myna Mab. (190 e). Blackish-brown, with a similarly coloured stigma, and 4 large hyaline white viyna. 

 spots, 3 postdiscal ones and 1 cellular spot. Hindwing with a small cellular spot and 2 near the distal margin. 

 Beneath lighter, the costal-marginal area behind the cell grey; the submedian spot is larger than above. 

 Panama. 



T. quadratus H.-Schaff. (190 d) has a double cellular spot, and only 2 postdiscal ones; on the hind- quadratus. 

 wing there are 4 postdiscal spots and the cellular spot is absent. Body and bases of wings with a famt bluish- 

 green reflection. Beneath the apical half of the forewing, and the hindAving are ferruginous-brown, the hind- 

 wing the lightest in the apical half, with the spots of the upper surface and a broad white anal angle of the 

 forewing. Brazil.
