﻿NEW SPECIES OF RHOPALOCERA FROM CHINA. 187 



majority of my reagents were eminently disappointing, and my 

 original expectations altogether too jubilant. It is only by 

 experience, however, that one can learn ; and, acting on mine, I 

 propose in my future researches to limit the number of reagents 

 very materially. It may, perhaps, be convenient to group those 

 that I have found of real use, stating them in order of merit, as 

 near as may be : — 



Hydrochloric acid. Ammonia. 



(Nitric acid (50 per cent.) Sulphuric acid (25 or 50 per 



[Potassic hydrate (25 per cent.) cent.) 



10 per cent, potassic hydrate.

NEW SPECIES OF RHOPALOCERA FROM CHINA. 



By J. H. Leech, B.A., F.L.S , &c. 



The following species are, I believe, new to Science, and were 

 obtained last year by my collectors Messrs. Pratt and Kircheldorff, 

 in the province of Setchuen, North-west China. 



Erebia ruricola, sp. n. 

 $ . Dark brown : central area of primaries blackish, outer third paler ; a 

 large black spot with two white pupils and faintly encircled with pale brown 

 towards apex : there is often a white dot towards anal angle of secondaries. 

 Under surface grey-brown : on primaries the ocellus of upper surface is 

 reproduced, and is ringed with pale fulvous ; below it is a smaller ocellus, 

 and there is sometimes a still smaUer one between them, placed on the edge 

 of the former ; below apex there is a reddish brown cloud, and there are 

 indications of a band of the same colour between large ocellus and discal 

 cell : the secondaries are traversed by reddish brown lines, the most con- 

 spicuous being two broad ones from middle of costa which terminate just 

 before median nervure, and one from middle of abdominal margin to outer 

 margin ; there is a submarginal series of white dots ; the outer margin and 

 centre of the wing are also dashed with white. Expanse, 58 mm. 



Four specimens taken at Ta-Chien-Lu, and two at Wa-Shan, 

 in July. 



Nearly allied to E. saxicola, Oberth. (Etud. d'Ent. ii. p. 32, 

 pi. iv. fig. 1), but the white pupils of apical ocellus are placed 

 more directly one under the other; the antennae are pale brown, 

 and the clubs are black beneath. On the under surface the colour 

 of primaries is different, and there is an additional ocellus towards 

 outer angle ; the markings are more distinctly defined on the 

 secondaries. 



Erebia rurigena, sp. n. 



$ . Dark brown, with a slight yellowish tinge in certain lights. 

 Primaries have a blackish cloud-like fascia from inner margin to centre of 

 the wing; the ocellus towards apex is large, conspicuously ringed with pale
