Hab. Silhet. 



Anterior wings fuscous black, witb a chocolate or vinous hue 

 in certain lights ; the base darker, with several small bright blue 

 dots, followed by four rosy spots, one on the costa, one nearly 

 opposite to this below the cell, two in the cell rather farther from 

 the base ; the margin with a series of white dots divided into two 

 parts by the nervules and bordered with blue, between which and 

 the cell are six small dots placed in two transverse series, and 

 also a seventh placed more internally near the third of the inner 

 series. Posterior wings of the same colour, with a broad blue 

 patch commencing on the costa beyond the middle, occupying 

 the outer angle and extending along the outer margin nearly to 

 the anal angle, preceded by one or two detached spots of the 

 same colour, and marked by a series of submarginal white spots, 

 preceded by three others of the same colour near the apex. 



Below, the posterior wings want the blue border, have the anal 

 angle blue, a red spot in the cell followed by four blue ones with 

 white centres ; the anterior wings have the spots larger and bluer 

 than above, and also have several additional spots on the disc. 



Head, thorax and abdomen black, spotted below with white, 

 the terminal segment of the last shining olive-green, especially 

 in the males. Antennae blue, pectinated in both sexes, not dif- 

 fering remarkably in their structure.

Closely allied to B. Sanguiflua, Drury {Am. Sanguiflua, Hope), 

 but at once known by the absence of the purplish red veins.

Hah. India Septentrionali. 



Wings fuscous black, somewhat diaphanous : the anterior with 

 numerous pale yellowish spots, viz. a series of small rounded dots 

 between the costa and costal nervure, alternating for some di- 

 stance beyond the base with a series between the costal and sub- 

 costal nervures, two series in the cell, of which the upper are 

 elongate-quadrate, the first and second of the lower series round, 

 the first being very small, the third almost reniform, the fourth, 

 fifth and sixth elongate, and the second round ; a series of rounded 

 dots in the interstices between the subcostal and discoidal ner- 

 vules, a similar series and a solitary spot in that between the se*
