276 Mr. W. F. Kiiby on 



basal cell, triangle u'itli a cross-nervuie just above the 

 n)icldle, and followed by three rows of cells, only increasing 

 towards tlie margin, subtriangular sj)ace consisting of 3 cells; 

 upper sector of the triangle rising from its extremity, the 

 latter separated, and rising considerably below. 



Hind wings with 11-12 antenodal and 10-11 postnodal 

 cross-nervures ; two cross-nervures in the lower basal cell ; 

 triangle with 1 or 2 cross-nervures, its base somewhat nearer 

 the base of the wing than the arculus, and its apex not 

 extending to the level of the triangle of the front wings. 

 'J'riangle followed by one row of 3 cells, and several rows of 

 2 increasing; sectors rising from a point. 



Membranules smoky grey, that of the hind wings followed 

 by a smoky shade over the cells which immediately border it. 



Female. — Upper part of the head bronzy green, with the 

 conspicuous yellow frontal ocellus ; face from the lower part 

 of the frons to the rhinarium inclusive yellow, except for 

 very narrow black sutures ; below this to the mentum bronzy 

 black, except a yellow spot at the base of the mandibles ; 

 mentum black in the middle, with the sides broadly yellow. 

 Thorax and pleura nearly as in the male, but the pleura 

 brighter yellow, and marked with 3 black depressed spots : 

 2 higher ones just in front of each of the metallic-green 

 bands, and 1 lower one a little behind the first pleural green 

 band. Interalary spots dark yellow, much larger than in the 

 male, and a much broader stripe of the same colour, expanded 

 on the front segments, running over the carina of the abdomen 

 to the end of the seventh segment ; the slightly inflated 

 basal segments are mostly of the same colour, which is con- 

 tinued by a row of long lateral S|)ots, gradually shortening, 

 as far as the seventh segment. Legs bronzy black, femora 

 finely denticulated, and with terminal seta3 ; front femora 

 pale beneath. 



Wings rather deeper-coloured than in the male, and more 

 clouded towards the tips. Fore wings with 1(3-17 antenodal 

 cross-nervures, the last discontinuous, and 10-11 j)OStnodais. 

 !Nodal sector more arched towards the extremity than in the 

 male, the space between the nodal and subnodal sectors thus 

 widening considerably just before the extremity, where it 

 again contracts. Triangle crossed by one or two cross- 

 nervures ; lower basal cell with two cross-nervures ; mem- 

 branule small, brown ; other characters as in the male. 



Hind wings with 11 antenodal and 11 or 12 postnodal 

 nervures. One cross-nervure only in the lower basal cell; 

 triangle traversed by 1 ncrvure ; membranule brown, as are
