Mr. Prter on new species of Lepidoptera . 233 



black line or row of spots : h.w. with a broad conspicuous 

 wliite streak edged with black from abdominal margin to costa, 

 a, A^ery narrow double Kne along outer margin, Avith three small 

 l)lack s23ots on the oiiter half of the mai-ginal line, and a minute 

 white or silvery spot above the last black one, anterior angle 

 considerably indented. Expanse of wings 1 1 lines. 



About streams at the Snowy Valley (Chekiang Province), not 

 common. 



Hi/drocampa interruptalis, n. sp. PI. IV, f. 5. 



PrcA'ailing coloiu- ochraceous-yellow. F.w. with a Avell marked 

 l)lack ring, with Avhite l)upil, side by side above it are tAvo more 

 Avdiite spots nearly surrounded with black, on outer margin is an 

 irregular black streak, very slightly divided by the ground 

 colom in the middle. H.av. on inner half a black line starts 

 from costa, proceeds nearly to anal angle, and returns to costa, 

 on the outer half more or less elboAved in the middle of its 

 iipward course ; from the apex of the elboAv to the costa a short 

 liroAvn mark margined with black ; a broad white transverse 

 streak on the inner half of wing towards the middle, and a 

 second broad white mark from costa half across the Aving on 

 outer half ; a marginal irregular Avhite streak interrupted aljout 

 the middle. 



This species is subject to much variation, in one specimen 

 the black hne described above as starting from and retui-ning 

 to the costa of h.AV. merely crosses the Aviug to the abdominal 

 margin, and the elboAved Hne instead of being an unbroken and 

 distinct continuation of it, starts considei'ably nearer the anal 

 angle ; and in another specimen the entire marginal Avhite streak 

 both in upper and loAver Aving is not interrupted at all. Expanse 

 of Avings 11 lines. 



Common on some ponds about Shanghai. 



Ilydrocampa nigroUnealis^ n. sp. PI. IV, f. G. 



Ground colour broAvn, markings much the same as in U. 

 interni/jtalis, the Avhite sjDots and black Hnes being boldly and 

 distinctly marked : h.w. including the very narroAV fringe line, 

 with seven black transverse lines, and a black edged large Avhite 

 mark just beloAv the costa in the centre ; an uninterrupted Avhite 

 line, elbowed in the middle, and black edged on both sides, 

 extends from the costa, outside the Avhite mark, to the abdominal 

 angle. Expanse of wings 1 inch. 



Occasionally taken on jionds round Shanghai.
