230 LEPIDOPTEBA INDICA. 



Genus GECANA, nov. 



Differs from the genus Pola in the male, in having vein 3 of the forewing emitted 

 from the middle of the cell, 2 from one-fourth from the base, the lower margin of the 

 cell straight, a small round inconspicuous patch of androconia on the upperside, 

 near the middle of the wing, between veins 2 and 3, very slightly overlapping 

 these veins.

Imago. — Male. Upperside bright chocolate-brown, with a distinct orange-ochreous 

 tint in fresh examples. Forewing with the disc slightly paler, a bright orange-red, or 

 orange-vermilion sub-costal streak, somewhat narrow and fining to a point a little 

 beyond the middle of the wing, a rounded clump of deep black scales a little before 

 the middle of the first median interspace, touching vein 3 and slightly overlapping 

 vein 2. Hindwing without markings. Cilia of forewing grey, of hindwing bright 

 ochreous-vermilion, narrow at the apex, gradually widening to the anal angle, and 

 extending narrowly up the abdominal margin for a short distance. Underside paler 

 than above. Forewing with the hinder marginal space pale ochreous, with obscure pale 

 ochreous spaces in the middle of the three interspaces above the hinder margin, 

 decreasing in size upwards, the base of the wing with the usual black spot on a small 

 ochreous-vermilion mark. Hindwing with a small patch of similar colour at the base 

 containing the usual black basal spot, all the veins ochreous-vermilion, a few short 

 streaks of that colour in the interspaces in the disc, with longer streaks towards the 

 abdominal margin. Cilia of both wings as above. Antennee black, ochreous beneath ; 

 palpi ochreous, with vermilion sides, last joint black ; head and body above concolorous 

 with the wings, thorax with long iridescent greenish hairs, abdomen with vermilion 

 tip, on the underside the body and legs are ochreous-vermilion, abdomen with blackish 

 segmental lumds at the sides. 



Female like the male above and below, the sub-costal streak is very narrow, and 

 of course there is no male mark. 



Expanse of wings, $ ? 2y%- to 2\ inches.
