854 MR. A. G. BUTLER ON BUTTERFLIES FROM JAPAN. [NoV. 15, 



maries above with the basi-internal half, excepting the costal border 

 and veins, bright cobalt-blue changing to ultramarine, the remainder 

 of these wings dark shining cupreous-brown, the fringe tipped with 

 white : secondaries cupreous-brown, paler than the primaries except- 

 ing towards the outer margin, fringe tipped with white : body grey- 

 ish brown. Under surface with almost the pattern oiT.fasciata, but 

 greyer in tint and with all the markings sharply defined, the white 

 stripe purer in colour, broader and more curved ; the primaries with 

 two slender submarginal whitish lines in continuation of the luuu- 

 lated hnes of the secondaries, and enclosing two distinct and a third 

 indistinct blackish spot on the inferior half of the external area ; 

 orange spots of secondaries deeper in colour. Expanse of wings 

 1 inch 5 lines.

T. regina is of the usual size of T. quercus. 



Thecla signata, Butler. 



Allied to T. arata and T. tyrianthina. Primaries above with the 

 discoidal cell, the interno-median interspace almost to outer margin, 

 and the basal half of the median interspaces bright pure lilac, the 

 remainder of the wing and the veins dark brown shot with lilac ; 

 secondaries rather pale fuliginous brown with bronzy reflections, the 

 discoidal cell sprinkled with lilac scales. Wings below pale golden 

 brown : primaries with two slightly darker spots in the cell, margined 

 and partly connected by silvery-white lines ; a slightly oblique band 

 from costa to first median branch, edged on both sides with silvery- 

 white lines ; a submarginal series of indistinct white lunules, the last 

 two of which bound two dusky spots; internal area shining whitish; 

 fringe dusky : secondaries with two abbreviated silvery-white lines 

 across the base of the subcostal area, the inner one curved ; a nearly 

 M-shaped character of the same colour crossed by the median vein ; 

 two widely angulated, slender, interrupted white lines from the abdo- 

 minal margin to the median vein ; an oblique white line from the 

 costal margin to the first median branch, and a chain-like double 

 white line from the apex to the second median branch ; a large black 

 spotted orange spot on the anal area (the anal tiiird of the wing is 

 ragged on both sides ; but from what remains of the anal patch, it 

 appears to be of the same character as that of T. arata). Body white, 

 the venter creamy, the tarsi annulated with black. Expanse of wings 

 1 inch 3 lines. 



Kuramatsunai, August. Coll. M. Fenton. 



Thecla signata may be placed between T. arata and T. tyrianthina, 

 although in some respects very unlike either. 



Strymon fentoni, Butler. 



Nearly allied to 8. tv-album of Europe, but quite as large as S. 

 spini ; under surface like the latter species in tint, but with almost 

 the pattern oi S. w-albvm ; the discal line of the primaries, however, 

 is more arched and continuous, that of the secondaries is more trans- 

 verse, and therefore does not run inwards in the direction of the base ;
