232 AOROBASIS ANGUSTKLLA. 



tapering a little posteriorly ; the frontal plate polished, 

 the anal one not so conspicuous ; the segments 

 tolerably well-defined ; the skin soft, and sparingly 

 clothed with very short hairs. 



There are two forms. 



Var. 1 has the ground colour dull dingy green ; the 

 head is brown, marked with still darker brown ; a dark 

 green pulsating vessel forms the dorsal stripe; on each 

 side, and on each segment, between the dorsal stripe 

 and the spiracular region is a large rust-coloured mark, 

 in some specimens a double mark, as it is divided 

 transversely in the middle ; there is also a less con- 

 spicuous series of rust-coloured marks on the spiracular 

 region. The frontal plate corresponds with the ground 

 colour, but has a smoky mark in the centre behind, 

 divided by the dorsal stripe, which is there distinctly 

 paler; on each side of this plate is a rather large 

 intensely black spot; the anal plate is darker than the 

 ground colour ; the spiracles are black, and are very 

 minute, except those on the second and third segments, 

 which are larger. The ventral surface is uniformly 

 pale green. 



Var. 2 has the ground colour ochreous-yellow ; the 

 head is wainscot-brown, the mandibles darker; the 

 dorsal stripe is brown, and the large marks between it 

 and the spiracular region are rather bright reddish- 

 purple; the frontal plate is wainscot-brown, divided by 

 a pale mark as in var. 1, and on each side of it is also 

 the large intensely black spot ; the spiracles are black. 

 The ventral surface is uniformly very pale greyish- 

 yellow. 



When first hatched the young larva evidently eats 

 its way into the seed-berry, and feeds on the inside, 

 and even the full-grown one is entirely hid in the 

 interior, though its presence is readily detected by a 

 neat circular hole in the side of the berry, through 

 which the frass is extruded. Some of the larvae came 

 outside to pupate, but I am not sure that all did. 



The first moth emerged on the 27th of June last,
