it differs in its larger size (1°4 as against 1-2 inches in alar expanse), 
the transparent apical area of the forewing is traversed by five instead 
of four veins, the abdomen beneath is pale yellow not bluish-white, and 
the femur and tibia of the hindleg are not clothed with dull chestnut- 
red and yellow hairs, the hairs being entirely yellow. From the 
ficure of the type specimen of M. hulluana in Ul. Lep. Het. B. M., 
vol. vii, p. 98, pl. exxxv, fig. 12 (1889), it chiefly differs in the 
apex of the forewing being much more produced and the hindleg 
being much longer. 
Described from a single specimen, which I have named in honour 
of Colonel C. T. Bingham, so well known in many branches of 
Natural History, who captured it and presented it to me.
