Mr. J. H. Leech's new species of Rhopalocera. 23 



two prominent tubercles, the anterior one prolonged into a sharp point, the 

 posterior conical. Elytra strongly punctured, rounded and ciliated at the 

 apex, each with two pencillated centro-basal crests, the outer one much 

 shorter and less elevated. Anterior femora (male, ?) with a broad tubercle 

 on the middle of their upper edge, the tibiae obtusely dentated within, below 

 the middle. Long. 16 millim. 



The lateral tubercles of the thorax are much more developed 

 in this species than in other members of the group of genera 

 approximately allied to Niphona. The broadly rounded apices of 

 the elytra are also peculiar ; but in all its other characters it 

 agrees with the numerous other species of Ocheutes that I have 

 examined. 



'NEW SPECIES OF EHOPALOCERA FROM NORTH-WEST 



CHINA. 



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



My collectors, Messrs. Pratt and Kricheldorff, have just 

 returned from China, and have brought with them a very fine 

 collection of Lepidoptera, obtained at Omei-Shan and some other 

 districts nearer the Thibetan frontier. 



Among the species comprising the collection are the following 

 twenty-three Ehopalocera, which I believe are new to Science : — 



Lethe simulans, sp. n. 

 (?. Nearly allied to Lethe nigrifasciata, Leech (Entom. xxiii. p. 28), but 

 much smaller in size and darker in colour ; the black transverse band of 

 primaries is inconspicuous, and is not dilated at any part of its outer edge : 

 on the secondaries the black marginal spots are similar to those of L. nigri- 

 fasciata. Fringes brown. Under surface greyish brown; basal half of 

 primaries darker, limited by a fairly broad brown fascia, which is not edged 

 with paler as in L. nigrifasciata ; there are two brownish bars in discal cell: 

 all the ocelli of secondaries are distinctly ringed with bluish white. Expanse, 

 60 mm. 



Four male specimens captured, in July, at Omei-Shan. 



This species is superficially like Lethe tristigmata. Elwes 

 (Trans. Ent Soc. Lond. 1888, p. 318, pi. viii. fig. 1), but is dis- 

 tinguished by the different colour of under surface, angulation 

 of transverse lines, and character of apical spots. 



Lethe calisto, sp. n. 



(? . Allied to Lethe nicetas Hew., with which species it agrees in many 

 respects, but may be distinguished therefrom by the romider wings, absence 

 of any red in the composition of the brown coloration of all the wings, and 

 of black spots on secondaries ; further, the primaries are devoid of markings, 

 and the fringes of all the wings are wliite chequered with blacldsh. On the 

 under surface the primaries are fuscous grey-brown, with markings siiiiiUu- 

 to those of L. nicetas : the secondaries are grey-brown, with the basal half 

 traversed by four silvery-lilac lines ; the outermost of these lines, sinuate to
