Leucophasia gigantea. (Plate XXXVI. figs. 10, ll.) 
Leucophasia gigantea. Leech, Entomologist^ xxiii. p. 45 (1890). 
S . White. Primaries with a large black spot on the second disooidal uervule, sometimes extending 
upwards to the first : a smaller one on the discocellular. Under surface of primaries with the 
l)lack spots faintly reproduced. Secondaries have an angulated suffused band indicated by a 
blackish costal streak, and a curved mark between the diseoidal and third median nervules ; a 
short black bar at end of diseoidal cell ; the venation is dark, especially on the secondaries 
and outer margin of primaries. Head black ; collar yellow ; thorax black dusted with white ; 
pectus sprinkled with yellow ; abdomen white. 
2 . Under surface of secondaries and apes of primaries tinged with yellowish, the black markings 
more band-like, with the addition of a zigzag black submarginal line ; all these markings are 
faintly seen through from above. 
Expanse, <S 48-62 millim., $ 72 millim. 
The specimens of the May brood are without black spot on primaries, the 
colour is more creamy, and the venation appears more prominent. I propose 
the name oi immacula for this seasonal form (Plate XXXVI. fig. 10). 
The type is separated from the other species of Leucophasia by the large 
black spot on primaries, and both forms are distinguished by the yelloAv collar. 
A fine series taken at Chang-yang, Central China, in May and August. I 
liave also received specimens from the province of Kwci-chow, Western China. 
Genus SERICINUS. 
Sericmus, Westwood, Trans. Eut. Soc. 1851, p. 173 ; Geii. Diuro. Lep. ii,, App. p. 530 
(1852). 
" Labial palpi nearly double the length of the head, nearly horizontally porrccted, liirsute (not 
clothed with long bristles). 
"Anlennce only slightly clavate, about thirty-jointed, gradually thickening. 
■' Fore wings triangularly ovate, rounded at the tip. Postcostal vein four-branched ; branches 
simple : the first and second arising before the extremity of the diseoidal cell, the third from 
its apex, and the fourth in the middle of the space between its apex and the tip of the wing. 
Upper discocellular vein very short ; the middle one much longer, annulated in the middle ; 
lower discocellular shorter, being almost contiguous with the extremity of the median vein. 
" Hind wings suboval, with the third branch of the median vein produced iiito a very long and 
narrow tail ; at the base of the wing is a minute prsdiscoidal cell.
