dorsal marbled dark-brown line which is broken up into minute spots on the 

 front half of segment 2 ; these lines coalesce with a dark brown dorsal line on 

 segment 4 and a lateral diffused brown band ; the rest of the larva is black-brown, 

 reddish on segment 11 dorsally and lighter laterally on all segments. There 

 are some fine erect hairs in two rows on segment 2 and some about the spiracles 

 of that segment ; a sub-dorsal and supra-spiracular hair on all other segments. 

 The prolegs are all small ; the true legs large, horny white, mottled with 

 brown ; the labrum and antennas white, jaws black. L. 36mm. ; B. 9mm. 

 Feeds on Casuarina equisiti folia, Cassia, Acacia arabica, &c., &c. 

 The pupa) of the male and female are very different though both enclosed 

 in the stick-cocoon, otherwise the larval case. The male 

 Pupa. pupa is an abnormal looking noctuid one w r ith very short 



wings, very swollen antenna), broad at the base and more 

 swollen on the outside margin than on the inner ; the wings only reach segment 

 7/8 ; the head is small and bowed and has a broad dorsal carination which 

 comes to a point in front ; the vertex is in a plane at 90° to longitudinal axis of 

 pupa ; segment 2 is in a plane at 45° to that axis and both margins are bent 

 back towards thorax to form a point or angle in the dorsal line and there is a 

 prominent carination along the dorsal line ; the thorax is considerably convex 

 and the dorsal line slopes from its apex to segment 2 and segment 4, its hinder 

 margin is a semi-elliptical curve ; the thorax is rather long ; the abdomen is 

 circular in transverse section and bent down at the end where there are two 

 short points ; the pupa is broadest across segment 2-3 and highest at thorax 

 apex. r l he body surface is somewhat shiny, especially on thorax, and is 

 transversely wrinkled ; the veins of wings are prominent ; there is a jaggedly 

 toothed ridge on front margins of segments 10 to 12, not reaching the spiracles. 

 Spiracles of segment 2 not visible ; the others are raised, broadly oval, shiny 

 with an open slit dividing them into two unequal parts. Colour is dark red- 

 brown, lighter on abdominal segment margins, very dark on segments 1-3 and 

 wings. L. 15 mm. ; B. 4 mm. 



The female pupa is a cylindrical body with a blunt point at the anal end and 

 no vestige of what could ordinarily be called a head ; the front part is, ventral- 

 ly, a mass of corrugated skin and, dorsally, segments 1 and 2 are not visible or 

 distinguishable ; segments 1 to 5 are all contracted together ; the surface of the 

 pupa is wrinkled transversely and has some deep irregularly-shaped pits in the 

 lateral abdominal region ; the middle 5 segments are very large and distinct ; 

 the spiracles are broad, flush, oval. The pupa is broadest at segment 11 and 

 diminishes towards head. L. 19 mm. ; B. 9 mm. 



The larva makes a cocoon of sticks placed side by side parallel to the body and 



quite cylindrical in shape, the sticks being often of slightly 



Habits. unequal length, the inside being thickly coated with silk 



which holds the structure together. The inside lining is 



produced beyond the mouth of the stick-case and this free portion is used to 



attach the whole structure to the twigs, branches, &c, where the insect lives ; the
