KELLICOTT. 105 



some specimens, black in others ; labium yellow at the 

 sides, black at middle, in one specimen the yellow parts 

 are olive to brown. There is so much variation in 

 these parts, that definite statements regarding them 

 can not be formulated. Thorax in one specimen 

 yellowish on the sides with two black bands, in 

 another the yellowish is entirely absent. Fore wings 

 hyaline, fuscous or black as follows : apex from distal 

 part of pterostigma; a patch beginning at costa, 

 nearer the pterostigma than the nodus and extending 

 backwards half way across the wing; this patch is 

 narrowed oi nearly divided near its middle, making it 

 somewhat hour-glass form ; and a patch beginning at 

 nodus below the subcosta and extending towards the 

 base of the wing; at some point between nodus and 

 triangle this patch is divided, sending a superior 

 branch to base between subcostal and median veins, 

 and an inferior branch to beyond the inner side of the 

 triangle between the sectors of the arculus ; a small 

 patch including the superior part of the triangle con- 

 nects with the inferior branch and sends a spur 

 towards the base of the wing between submedian and 

 postcostal veins. This spur and the superior branch 

 mentioned above may or may not be interrupted by 

 clear spaces. In the hind wings the apex and patch 

 before the pterostigma are as in the fore wings, except 

 the latter may be entirely divided. Distally the basal 

 patch may be bounded below by the lower sector of 

 the arculus or it may send back a process which in 

 extreme cases reaches the lower sector of the triangle ; 

 the basal patch, also includes the entire triangle and a 

 basal process which extends backwards and terminates 

 on a level with the distal end of the membranule ; in- 

 cluded within the basal patch is a hyaline patch which 

 occupies the space between median and submedian 

 veins to arculus, and the space between median vein 

 and superior sector of the arculus to a point above the
