segment ; mid-tarsus with comb ; paronychium and pulvillus 

 present. 



" £. Tenth segment simple ; tergite narrow, sides parallel 

 or slightly slanting distad ; apex sinuate, truncate, or entire ; 

 .sternite boat-shaped, shorter than tergite. Clasper with 

 friction-scales, which vary in size and number ; harpe slender, 

 simple, mostly somewhat spatulate. Penis-sheath with a right 

 and a left process, the one or the other sometimes not detached, 

 being replaced by a series of teeth. 



" ?. Vaginal plate elongate triangular, tip truncate, 

 edges somewhat incrassate ; orifice large, free, with the edges 

 somewhat raised but simple." (Roths. & Jord., 1903, p. 533). 



Egg. — Shortly ovoid, surface shining and smooth except 

 under the microscope, colour variable. 



Larva. — Chcerocampine in shape, head semi-elliptical, body 

 long and thin, tapering strongly frontad from segment 5, 

 rest of body cylindrical, of less diameter than 5 ; venter of

4 and 5 somewhat flattened ; colour green, more or less 

 strongly marked with brown, and an ocellus with enamel- 

 like surface on 5. 



Pupa. — Chcerocampine in shape ; basal part of tongue in 

 a laterally flattened sheath ; cremaster with many hooks and 

 spines ; colour green or grey with dark markings. 



Habits. — Eggs laid singly on plants of the family Aroidese. 

 In the later instars the larvae feed chiefly at night, and hide 

 during the day low down on the stem of the food-plant or 

 on the earth or tree-trunks close by. They adopt a snake- 

 like attitude when alarmed. The colour becomes darker 

 before pupation, which takes place in a rough cocoon on the 

 surface. The cremaster of the pupa is fixed firmly by its 

 hooks to the silk of the cocoon The moth rests with the wings 

 nearly horizontal.
