the dorsal slope of segments 11-14 is more considerable, the 14th or anal seg- 

 ment being suddenly narrower than the preceding one and ending square 

 behind ; there is a kind of fleshy tooth at the common margin of segments 12 

 and 13 on the dorsal surface of which are situated the extensile organs of seg- 

 ment 12 which, when protruded, are short cylinders with tubercled, knob- 

 like extremities; the gland on segment 11 is circular in shape; on the dorsum 

 of segment 14 there is a depressed, shining, glabrous, central, large, green space. 

 The head is roundish, shining, light red-brown in colour with black mandibles. 

 The dorsoventral margin is more or less flanged, the flange romided in transverse 

 section and more or less translucent-looking. The surface of the body is covered 

 with minute, curved, thick-topped hairs, the ventrum with minute tubercles ; 

 the posterior margin of segment 14 and front margin of segment 2 are set 

 with simple, erect hairs and there is a single, curved, erect hair at each lateral 

 angle of the dorsal depression of segment 2 as well as a single, subdorsal one 

 on the middle of each segment 5-9. The spiracles are the colour of the body, 

 white-centred and of ordinary size, circular. The colour of the body is light 

 green or rose, with a double, lateral, diagonal band to each segment 5-10 run- 

 ning down and back, the posterior half of each band being dark-green, the front 

 half whitish ; there is a broad, dark green, lateral band with the upper edge 

 white-bordered on segments 2-4, that on segment 2 being narrowest ; a dark- 

 green, dorsal line from end to end ; the anal segment has two subdorsal, whitish 

 bands as well as a dark-green dorsal one ; segment 2 has a dark-green, dorsal 

 band ; besides which there is a subspiracular greeny -white or rose-coloured 

 band; all the diagonal lateral bands end on the subdorsal line and do not 

 meet on dorsum ; ventrum dark-green. L : 20 mm ; B : 5 mm ; H: 4 mm. 



Pupa. — The shape is quite normal, the anal end being rounded, the front 

 also ; the head is hidden under segment 2 ; segment 2 transversely convex with 

 a considerable dorsal slope which passes smoothly into the similar dorsal slope of 

 of thetransversely convex, slightly laterally compressed thorax which is somewhat 

 broader than segment 2 with rounded shoulders ; the breadth of pupa is the 

 same from the shoulders to segment 7 so that the lateral outline is there straight ; 

 anal segment slightly turned under ; the ventrum of pupa flattened. The 

 surface of the pupa is minutely roughened with minute muslu'oom-shaped 

 hairs, i. e., hairs with thick stems and circular, disc-shaped tops ; on segment 

 2, there is a subdorsal, central, minute, conical tubercle. Spiracles of segment 

 2 prominent, oval, white ; the rest are glassy, prominent, oval, light-coloru?ed. 

 The colour of the pupa is dark brow'n-pinkish, blotched with blackish ; a 

 blackish dorsal line and a lateral row of large, glassy, black, depressed, circular 

 spots, one to each abdominal segment ; ventrum light. L : 12 mm. ; B : 4.5 

 mm. ; H : 4 mm. 



Habits. — The single egg is deposited upon shoots, stalks, leaves 

 after a minute inspection of sites by the butterfly and, often, amongst 

 a lot of ants that stroke her legs with their antennae. The little 

 larva, upon emerging, eats only the young parts and seems to be 

 particularly fond of the gland at the base of the leaf which is 

 found in Acacia -pennata upon which it is always found. When full 

 grown and in the last few stages the caterpillar is difficult to find 

 because of the cryptic colouring, the diagonal bands having 

 the appearance of the rows of little leaflets along the branches of the 

 leaf. The pupation takes place in a crevice or on a leaf, on the upper 

 surface or below as the case may be, &c.; and the fixings are quite 

 normal. The butterfly can fly quite strongly but never goes far ; it
