Genus TOTHRIX, nov. 



In the male, vein 3 of the forewing arises close to the lower end of the cell, vein 2 

 from close to the base, the lower margin of the cell straight, the sex marks on the 

 upperside of the wing consist of four or five short streaks of androconia, along the 

 middle of the median branches and in the interno-median interspace, in an inwardly 

 oblique square patch, sometimes more or less joined together ; the hind tibise much 

 swollen.

Imago. — Male. Upperside olive-brown. Forewing with a sub-costal, dull 

 orange-ochreous streak, the lower middle area from near the base for three-fourths its 

 length covered with dull orange-ochreous hairs, some of them extending into the lower 

 part of the discoidal cell, within this dull ochreous area the sexual brand 

 is placed, consisting of four (sometimes five) thick black straight bands of 

 androconia, running parallel with each other from the sub-median vein into 

 the first median interspace, a little beyond the middle, the bars close 

 together, some of them sometimes joined together, forming a nearly square 

 patch. Cilia nearly white. Hindwing with all the inner area covered with 

 dull orange-ochreous hairs, leaving the costa broadly, and the outer margin 

 decreasingly dark olive-brown, somewhat darker than the ground colour of the 

 forewing. Cilia whitish at the apex, becoming orange-ochreous hindwards, dark, 

 rather bright orange-ochreous towards the anal angle. Underside a little paler than 

 the upperside, uniform in colour, there being but a slightly darker discal shade across 

 the wings, a somewhat obscure pale ochreous spot near the base of the second median 

 interspace, and a smaller similar spot inwards, in the first median interspace. Antennae 

 black, grey beneath ; palpi bright orange-ochreous, last joint black ; head and body 

 above concolorous with the wings, smeared with dull orange-ochreous on the head, and 

 with long hairs of that colour on the thorax ; the tip of the abdomen with some short 

 ochreous hairs ; body below concolorous with the wings, legs ochreous, the hairs on the 

 hind tibiae coloured like the l3ody.
