LYCJEmBM. 



wliitish V a central transverse row of seven ■whitish- edged black spots, the upper four united 

 and the seventh . placed inwards ; a submarginal series of six black spots outlined with 

 whitish ; the secondaries have a black discoidal spot and central and submarginal series of 

 black spots, all are outlined with whitish ; between the submarginal spots and the whitish 

 marginal line is a bright fulvous band towards anal angle. 



Female. Similar to the male, but the wings are more ample and the spots on under surface 

 are larger. 



Expanse, S 34-36 millim., $ 40 millim. 



This species agrees in many respects with T. herzi, Fixsen, but the tails of 

 secondaries are much longer, and the spots on under surface are less uni- 

 formly aiTanged. 



Examples of both sexes were taken by a native collector at Chang-yang in 

 June and July, at an elevation of 6000 feet. 



Thecla tengstroemi.

Lyccena tengstrcemi, var. davidi, Obertliiir, Etud. d'Entom. vi, p. 13, pi. viii. fig. 1 (1881). 

 Thecla tengstroemii, Baker, Trans. Ent. Soc. Lond. 1891, p. 27. 



" Expands 0-75 to 1 inch. Wings uniform brown above, with brownish marginal fringes. 

 Underside brownish grey. AU the wiugs with a hind marginal row of light spots ; there are 

 no spots upon the area of the wing." {Lanri, I. c.) 



Var. davidi, Oberthiir. " Bca:ucoup plus grande que iem/siroemi. En dessus, comme cette 

 espece, d'un bnin vcloute moins fonce pres la base des ailes que vers le bord exterieur; en 

 dessous, diflcrc do tenr/.stroemi par la dilatation de toutes les taches qui sont, en outre, 

 beaucoup moins rapprochocs les uncs des autrcs." (OheriJmr, I.e.) 



M. Oberthiir says that the type of L. tenfjsfroemi came from Tura and 

 adds : " M. I'Abbe David met with the remarkable geographical form which 

 I have named var. davidi near the north-east frontier of China. The female 

 of this form carries at the anal extremity a short tuft of fine compressed black 

 liair, similar to that of Thecla acacias and some other species of Lyca^nidse. 

 This very important cliaractcr miglit serve as the basis upon which to form a 

 new genus, but as tlic species having this character differ in other material 

 n-spffts, it would not be correct to place them in the same genus." 



Mr. George T. Baker, in placing tliis species in the genus Thecla, conclu- 

 sively proves that both by the neuration and sexual appendages tengstroimi 

 is more nearly allied to tliat genus than to Lycwna, and he suggests that its 

 proi)er iiositif)n is after T. lunulata, ErschofF.
