whitish ; 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. 
<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 arranged. 
Examples of both sexes were taken by a native collector at Chang-yang in 
June and July, at an elevation of 6000 feet.

" Expands 0-75 to 1 inch. Wings uniform brown above, with brownish marginal fringes. 
Underside brownish grey. All the wings with a hind marginal row of light spots ; there are 
no spots upon the area of the wing." (Lany, I. c.) 
Var. davidi, Oberthiir. " Beauconp plus grando que tcnysira'mi. En dessus, comme cette 
espece, d'un brun veloutc moins fonce prcs la base des ailes que vers le bord exterieur ; en 
dessous, differe de tenytifrasmi par la dilatation de toutes les taches qui sont, en outre, 
beaucoup moins rapprochees les unes des autres." (Oberthiir, I.e.) 
M. Oberthiir says that the type of L. tengsfroemi 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 
hair, similar to that of Thecla acacice and some other species of Lycaenidse. 
This very important character might serve as the basis upon which to form a 
new genus, but as the species having this character differ in other material 
respects, it would not be correct to place them in the same genus." 
Mr. George T. Baker, in placing this species in the genus Thecla, conclu- 
sively proves that both by the neuration and sexual appendages tengstrcemi 
is more nearly allied to that genus than to Lyccena, and he suggests that its 
proper position is after T. hmulata, Erschoff.
