222 LEPIDOPTERA INDICA. 



costal spot ; a spot posterior to the last io the middle of the cell ; a large spot posterior 

 again to the latter ; an elongated spot at the end of the cell ; a small spot posterior to 

 this ; the discal band much dislocated, the two anteriormost spots well separated and 

 shifted inwardly from the six spots which follow, touching the elongated spot at the 

 end of the cell ; the second portion of the discal band consists of six spots, which are 

 all conjoined, but are placed in pairs somewhat, the posteriormost of these just touches 

 the last spot of the discal series, which is placed on the abdominal margin ; a rather 

 prominent lunulated sub-marginal band ; a marginal series of oval dark spots ; the 

 anal angle produced, but hardly forming an anal lobe. 



Female. Upperside, both wings with the blue areas smaller than in the male. 

 Forewing with the costal black border reaching to the sub- costal nervure, and closing 

 the cell with a wedge-shaped projection ; the outer margin of the blue area quite 

 regular ; the outer margin of the wing nearly twice as broadly black as in the male. 

 Hindwing has the blue colour confined to a much smaller area on the middle of the 

 disc ; the discocellular nervules marked with a black line. Underside, both wings as 

 in the male, except that the ground-colour is a trifle paler. 



This species is a little like A. asotria, Hewitson, from Maulmein, which is still 

 unknown to me except from Hewitson's description and figure, but the blue coloration 

 of the male on the forewing is less extensive and has anteriorly an irregular edge ; the 

 shape of the hindwing is also different in ^4. asotria, the anal angle is quite round in 

 A. adela ; it is produced to a point so that the abdominal and outer margins together 

 form an exact right angle. The markings and coloration of the underside are very 

 close indeed to A. arvina, Hewitson, and A. aboe, de Niceville. (de Niceville.) 



Expanse of wings, <? ? l-ro inches. 



Habitat. — Burma. 



We have not seen this species ; de Niceville sent his whole collection of Arhopalas 

 to Bethune-Baker when the latter was writing his Monograph of the Amblj^podiinse. 

 After de Niceville's death his collection was purchased by the authorities of the Indian 

 ]\Iuseum, Calcutta, and as the rules and regulations under which they lend specimens 

 for scientific purposes are absolutely prohibitive, we have not been able to 

 examine any of the rarer species. After describing A. adulans, de Nice'ville 

 makes the following remarks : — " On the upperside both sexes of this species agree 

 almost precisely with A. adala, de Niceville, described above. On the underside, how- 

 ever, the ground-colour of A. adulans is distinctly darker and less reddish ; the pale 

 inner marginal area of the forewing is more extensive, reaching to the median nervure 

 instead of to the sub-median fold ; and A. adala possesses in the forewing a small costal 

 spot placed midway between the end of the cell and the discal band, which is wanting 

 in A. adulans. The female of A. adala (which I have not thought it necessary to 

 figure) has the blue coloration of the upperside considerably less extensive than in the
