175. TAPENA BUCHANANII, DE NICEVILLE. 



Celcenorrhinus buchananii, de Niceville, Journ. Bomb. Nat. Hist, 

 Soc., vol. iv, p. 187, n. 21, pi. B, fig. 2, $ (1889). 



" Habitat : Upper Burma. 



Expanse: ?, 2*1 inches. 



Description : Female. Very closely allied to C. laxmi, mihi, from 

 which it differs in its considerably larger size. Upperside,/0r<?wz>^ with 

 the white discal band fully twice as wide, not divided into spots, extend- 

 ing uninterruptedly from the costa to the submedian nervure, its edges 

 very irregular, its lower portion posterior to the first median nervule 

 much narrower than the rest of the band ; this species lacks the two 

 small obliquely-placed black dots found near the base of the submedian 

 interspace in C. laxmi. Hindwing instead of possessing two parallel 

 discal macular black bands has a rounded black spot towards the end 

 of the discoidal cell, and a discal series of six black spots, of which the 

 anterior one is round and well-separated from the spot which follows it, 

 the second spot is round, the next pair are the largest and elongated, 

 and the last pair smaller but also elongated; cilia of hindwing 

 anteriorly white, posteriorly dark brown. Underside, both wings with 

 the same differences as above, but all the spots of the hindwing more 

 prominent. 



I believe this to be a species distinct from C. laxmi, though a single 

 male of that species only is known, while C. buchananii is described 

 from a single female. The difference in size is very considerable, and 

 is more than is usually found in the opposite sexes of the Hesperiidce, 

 and the markings also shew marked differences. I have named it after 

 its capturer, Mr. A. M. Buchanan, who obtained it in the Ruby Mine 

 District, Upper Burma." (de Niceville, I. c.) 



With reference to the last paragraph of above description, Mr. de 

 Niceville informs me that his type of C. ( T.) laxmi was a female 

 and not a male, so that T. buchananii is undoubtedly a good species.

" Allied to Plesionfura : forewing less triangular, exterior margin more 

 convex, posterior margin longer ; cell narrow at end ; disco-cellulars extend- 

 ing very obliquely inward ; lower median branch at less than two-thirds 

 before end of the cell : hindwing very broadly oval, extremely convex 

 externally : abdominal margin short : cell much shorter, second subcostal 

 nearer end of the cell ; upper and middle medians both emitted from 

 extreme end of the cell ; lower median at less than one-third before the 

 end. Body short ; antennal club shorter, and thicker at tip, 



Type: Udnspes fdits." (Moore, /, r,)
