mora. S. niora Schaus likewise greatly resembles lutibasis, differing by orange-red tips of the antennae, 
yellowish-white, distally blue-bordered spots on the collar, orange-yellow tarsi. The abdomen exhibits also 
sublateral blue spots. The wings are brownish hyaline, veins, distal margin and internerval stripes in the 
marginal area are black; base of the proximal margin, costal margin and transverse vein red-brown. Costa 
Rica (Sixola), Panama (Chiriqui). 
meridensis. S. meridensis Schaus. Head and thorax black, with blue spots on head and collar. The 1st and 2nd 
ring of the blackish abdomen are yellow-banded, the other rings exhibit violet-blue lateral spots; at the 2nd 
ring there are yet yellow lateral spots and, as on the 2 following rings white sublateral spots. Legs black and 
blue striped, tarsi ochreous yellow, forehips opalescent. Forewings yellowish hyaline with black veins, margins 
and broad apex, subcostally and at the proximal margin light-brownish. Hindwing more whitish hyaline with 
a narrow black border and yellow costa. Antennae black, before the tips yellow. Expanse of wings: 35 mm. 
Merida (Venezuela). 
16. Genus: I^asyspliiaix Flclr. 
Siphon well-developed, palpi short, pointing straight foreward the whole body is densely covered with 
woolly hair; stoutly built. Veins of the wings as in Sarosa. 
mucescens. D. mucescens Flclr. (11 h) is one of the largest Syntomidae known, the whole body is thickly covered 
with black-brown hair being blue-green at the tips. Wings hyaline with fine black veins and distal margin; 
base, costal- and proximal margins and discal spot broad black, base with blue-green hair; proximal margin 
of the hindwing white. Expanse of the wings: 72 mm. Colombia (Bogota). 
volatilis. D. voiatilis Schaus. Much smaller than the preceding, black; the neck shows 2 large, white spots, 
the abdomen 2 rows of white spots, above as well as sublaterally; legs white-spotted. Wings hyaline with 
black veins and fringes; in the marginal area between the veins there are broad whitish stripes; base, costal- 
and proximal margins orange; on the hindwing the proximal margin and a dot at the angle of the transverse 
vein are black. Expanse of wings: 40 mm. Costa Rica (Volcano Poas). 
17. Genus: I^asiosceles Hmps. 
• The very peculiar species known so far stands rather isolated. The second palpal joint is long-haired 
and extends as far as the vertex, the third being moderately long. The male antennae are very short ctenodont, 
at the tips serrate-dentate. Thorax and base of abdomen thickly woolly-haired. The lower median vein of 
the forewing rises below the lower cell-angle, the-middle radial above. On the hindwing both the median veins 
and the lowest radial stand on a common pedicle, also the subcostal vein is petioled with the upper radial. On 
the upper surface of the hindwings the whole marginal half and an area extending along the submedian fold 
towards the base is covered with rough scent-scales. 
erythrozo- L. erythrozonata Hmps. (11 h). Head and thorax are deep blackish-brown with a blue reflection. 
initu. r p] loraXj anterior and middle hips and the greater part of all the femora are carmine. Legs otherwise black. 
The blue-black abdomen is above and at the sides banded in carmine. At the base of the first segment there 
are lateral, long, red hair-tufts. On the ventral side, between the 3rd and 4th segments, dense tufts of rather 
coarse whitish scent-hairs are protruding. The forewing is in the basal third and in the costal-marginal half 
velvety-black, otherwise greyish-brown. In the disk 4 hyaline spots beneath each other, the lowest being the 
smallest; behind the cell 4 similar hyaline spots. Hindwings black-brown with 2 hyaline spots behind the cell 
above and below the middle radial. The scent-scales are of a yellow-grey colour. — Before me are 2 male speci¬ 
mens, one from Panama (Chiriqui) from where the species was described, the other from Costa Rica (southern 
side of the volcano Irazu). 
18. Genus: Gyiinielist Wkr. 
It contains mostly robust species with a stout, round abdomen. The thorax is woolly-haired, the wings 
are broad. The shafts of the antennae are not thickened, in contrast with the genus Homoeocera which is other¬ 
wise very much like it. On the forewing the upper subcostal vein rises freely from the cell, whilst on the hindwing 
the lower median vein and the lower radial rise from a common pedicle. We quote the 3 species cocho, pitthea 
and chimaera, which are otherwise reckoned to this genus, though they look very differently, in the genus 
Pseudosphenoptera, since P. basalis seems to be the $ of pitthea ; both have several times been found in copula. 
hjrcea. G. lyrcea Druce (11 g). Body orange-yellow, thorax marked in black. The abdomen is yellow with 
black rings which grow broader above on the 3rd to 5th segments and form spots being metallic blue-pupilled. 
Beginning from the 6th segment, the abdomen is quite black with metallic blue transverse bands. The hyaline
