" Subtus alls nigro-fnscis, anticis costa apiceque griseo-atomatis, punctis tribus subcostalibus 

 minusculis albis ornatis. Fimbria obscure grisea. cS 2 15-16 mm." (Gr.-Gr.,l. c.) 



M. Grum-Grshimailo sent me specimens of his ' N.' ^re^ws from Nian-shan ; 

 they are smaller than the majority of the specimens of T. pelias and rather 

 paler and browner in colour. In markings, however, they are identical, and, 

 seeing how very trifling the differences are, the Nian-shan examples seem 

 hardly worthy of a varietal name, unless it should be ultimately found that 

 no intermediate forms occur. 



T. pelias is not uncommon at Ta-chien-lu and Wa-ssu-kow in the months 

 of June and July. 



Genus ISOTEINON. 



Isoteinon, Felder, Wien. ent. Mon. vi. p. 30 (1862) ; Watson, Proc. Zool. Soc. Lond. 

 1893, p. 83. Type, lamprospilus, Felder. 



" Genus Cijclopidi, Hiibu., Led., accedens, antennis multo longioribus, fere ut in Pterygospideis 

 clavatis abdominequo alas postieas baud superante priEsertim discrepat." {Felder, I. c.) 



"Antenna: club moderate, elongated, terminal crook short, tip acuminate. Palpi: second joint 

 densely clothed with short scales; third joint OYri, reaching well above the vertex of the 

 head, slender, obtusely conical. Fore wing : inner margin considerably longer than outer 

 margin; cell less than two. thirds the length of the costa; discocellulars erect; vein 5 

 slightly nearer to 4 than to 0 ; vein 3 close to end of cell ; vein 2 about equidistant from end of 

 cell and base of wing in the male, considerably nearer to base of wing in the female. Hind 

 wing narrow ; vein 7 shortly before end of cell ; discocellulars and vein 5 faint, but distinctly 

 traceable : vein 3 immediately before end of cell. Hind tibia; s])arsely clothed witli hairs 

 and with two pairs of spurs. No secondar}' sexual characters on the wings. 



" Many Indian species have been put into this genus ; none of those, 

 however, which I have been able to examine belong to it, the direction of the 

 third joint of the palpi alone readily distinguishing them. This genus 

 appears to be allied to Ilijnrotis, Moore.
