Imago. — Male and Female. Upperside uniform dark viuous-ljrown. Underside 

 paler brown, with two small indistinct ochreous-grey sub-apical spots close to the 

 costa, about one-sixth from the apex of the forewing, and two indistinct transverse 

 fasciae on the hindwiug, slightly darker than the ground colour, not always distin- 

 guishable, otherwise there are no markings aljove or below. Anteunte lilackish- 

 brown ; palpi, head and body above and below and the legs coucolorous with the wings, 

 except the abdomen, which is whitish on the underside. 



Expanse of wing.s, ,? $ ly-jf to ly% inches. 



The imago is fond of damp, shady places, like evergreen forests and beds of nallas. 

 We have bred many at all seasons and in many parts of the district ; it is always 

 plentiful where it exists, that is where its food plant grows. The flight is very weak ; 

 the insect keeps low down near the ground and pitches often on leaves ; it is rarely 

 found basking in the sun. 



Larva. — As in the group, not to be distinguished from Notocrypta feisthameli, 

 Boisduval, except that the head is smaller. Length, 31 mm. 



Pupa.— As in the group, not to be distinguished from that of N. feisthameli, 

 except by the snout (or beak) being slightly turned up. 



Habits. — The same as that of N. feisthameli in every particular. 



The larvae are verv stout when full grown, and have the habit of resting with the 

 first three segments after the head contracted so as to give the appearance of being 

 humped about the anterior segments, the small head lying with its apex pressed on 

 the second segment ; the body is flattened ventrally as the larva always lies closely 

 applied to the resting surface ; the anal segments are sloping, and the margin is 

 closely applied to the leaf, rounded at the extremity and somewhat thickened at the
