GELASTOCERA; KERALA; MORMONIA; CATOCALA. By Dr. M. Dbatjdt. 
14. Genus : CiJelastocera Btlr. 
duplicata. G. duplicata Wilem. has pale rosy brown forewings suffused with grey, the central area is intersected 
by an oblique, double, brown band. Costa has a short brown streak-like mark near the apex. Hindwings 
blackish brown turning to a paler ochreous outwardly. Wing expanse; 38 mm. Hondo, Yezo. 
insignala. G. insigtiata Wilem. Forewings pale brown, mottled with darker specks, anterior and posterior trans¬ 
verse lines indicated by black dots with a darker undulate line subterminally. Reniform stigma pale with 
2 black dots. Black dots at outer margin and a small spot in centre of inner margin. Hindwings blackish 
brown. Wing expanse: 20—26 mm. Japan, Shikoku and Kyushu. 
16. Genus: Kerala Moore. 
houlberti. K. houlberti Obth. Forewings glossily silky reddish brown bestrewn with black dots, especially on 
costa. Anterior transverse line dark brown, angulated. The posterior line is double and only slightly curved. 
Orbicular and reniform stigmata are very small, whitish. Beyond the subterminal line, there is a row of black 
longitudinal streaks. The brown marginal area is narrow. Hindwings glossily silky, impure white with a large 
brown basal spot, in the $ the subterminal area is dusted with grey. It is related to punctilineata Mr. from 
Assam and Sikkim. Wing expanse: 38—42 mm. Thibet (Siao-loo, Ta-tsien-loo). 
Subfamily: Catocalinae. 
1. Genus: Mormonia Hbn. 
dulana. M. dula Brem. (Vol. 3, p. 302, pi. 54 b). — dulana Strd. denominates specimens in which the whitish 
central area colouration is quite absent. Such forms, however, belong to the typical form and should not be 
denominated. The remark af Strand, that the hindtibiae only have spurs towards the base, certainly does 
not refer solely to the form dulana, but to dula in general. 
demacu- M. sponsa L. (Vol. 3, p. 302, pi. 54 b). — demaculata Heinr. has stigmata suffused with the ground 
lata. co ] oar an( | not filled with white. Described from the neighbourhood of Berlin, but probably occurring occasi- 
foriis. onally everywhere. — fortis Schaw. are specimens heavily suffused with black-brown, base, central and marginal 
areas appearing thus, only the stigmata and their surrounds remaining pale. The band of the hindwings more 
obscura. widely black. Bosnia. — obscura Obth. are very dark specimens without any white and partially submerged 
markings. Algeria and Tunis. Schawerda has described similar specimens a second time 3 years later under 
aira. the same name, as occurring in Lower Austria. — atra Spul. are still darker, forewings and thorax are com- 
pomerana. pletely blackened. — pomerana Diesterweg denotes a melanic specimen with black hindwings and only the 
purpurea, reniform stigma of forewings is faintly discernible and grey. — purpurea Obth. from Morocco is darker and 
with more intensive colouration and markings, hindwings being very dark. 
syriaca. M. neonympha Esp. (Vol. 3, p. 303, pi. 54 c). — syriaca Osth. is larger, forewings not ashen grey, but 
golden yellow, all transverse markings fainter and more diffuse. Marash (Taurus). 
belloidcs. M. bella Btlr. (Vol. 3, p. 303, pi. 54 f). — belloides Strd. is identical with Staudinger's serenides, 
which is distinguished by darker forewings that are less shaded with grey. It is therefore a synonym. 
2. Genus: Catoeala Schrk. 
aira. C. fraxini L. (Vol. 3, p. 304, pi. 54 d). — atra Spul. are extreme moerens with completely blackened 
caerules- forewings and thorax. — caerulesceos Class has forewings distinctly suffused with bluish, perhaps it is a 
C ns - transition to moerens. — contigua Schultz has a synonym in longimaculata Closs. — coeruleomaculata Gloss is 
\wrutco- a remarkable aberration with a blue patch in the black basal area of hindwings, otherwise it resembles the 
maculata. form moerens. Captured near Berlin. This may be an extreme form of maculata Kusnezov. — argillacea Vincent 
argiUacea. q as forewings grey-white as type, the black markings faintly indicated, but the transverse lines pale yellow, 
edged with black on both sides. The spot below the reniform stigma is also yellow. From Budapest and La 
latefasciata. Grange. — latefasciata Warn, is a form from the Amur, in which the blue bands of the hindwings are strikingly 
sternecki. wide, being about 2 mm wider than in european specimens. There is no other difference. Ussuri. — sternecki 
Hirschhe denotes a specimen bred at Prague, in which the blue band of the hindwings is double as wide as 
in normal specimens, it almost reaches to the inner margin and only a small black patch is left in basal area. 
Forewings do not vary.
