I.ana. — Xonual in !</i(i/i/> ; tlaugod all along the d(>rs<iveutral margin ; the 

 highest point is about the midiUe of the body ; the transvorso section is 

 somewhat triangular ; segment 2 is semicircular in shape seen from above, 

 rather thick, convex transversely with the dorsal central portion agaui 

 thickened above a spiracular, linear, length-depression which does not 

 reach the front margin, the central, dorsal depression not very large, 

 diamond-shaped, deep, light bottomed; the anal segment Hattened dorsally, 

 sloping gently to extremity, bntadly rounded at end, or even somewhat 

 squarish. Head, completely hidden by segment 2, is small, round, shining, 

 soiled yellowish-white ; the clypeus is triangular, large, bordered by a 

 soiled line ; the mandibles brown-tipped ; the eye-curve black inside. 

 Segment -'J is abruptly higher than segment '2 and more or less overhangs 

 the hinder margin of that segment with its middle, <lorsul, prominent 

 portion which is tumid between the dorsolateral lines ; segment 4, in a 

 similar manner, rises above the hinder margin of segment 3 ; segments 

 ■")-10 art' all dorsally slightly convex longitudinally; segment li^ has the 

 hinder margin curved strongly forwards in a simple, wide curve, the lateral 

 portion on each side forming thus, more or less, a lobe upon which is 

 situated the protrusible organ — the lateral portions of segment 12 are thus 

 longer than the dorsal part — which has, as usual, a circular mouth ; it is 

 indistinct when in repose being the colour of the rest of the surface more 

 or less, protruding white, cylindrical tubes with dilated, hair-set tops ; 

 segment 11 has the transverse mouth-shaped gland near its hinder margin. 

 Surface minutely shagreened ; besides, covered densely with translucent- 

 white, star-tubercles as also with conical tubercles ( these nearly all 

 on the coloured parts to which thej'^ actually impart the colour ) which 

 are red in colour and about the same size as the stars, all bearing a 

 short, longly-conical, colourless hair, the conical tubercle being generally 

 slightly inclined and more or less simple, dark-coloured sometimes, while 

 the longlj' conical hair is obconical and more or less erect ; some compara- 

 tively long — -still very short, however — hairs all round the dorsoventral 

 margins ; tliere may be a few slightly longer subdorsal hairs on segments 

 4 to 10; each segment 3-7 has a small, funnel-shaped, central, dorsal depre- 

 sion as well as a long, linear, lateral one at the bottom of which and in it 

 is situated the spiracle. Spiracles are small, round and raised, hollow 

 ins de, light in colour but not easy to see because in the depressions. 

 (Jol')icr of the body is apple-green, sometimes faintly sufl'used with rose and, 

 also only sometimes, with a dorsal and subspiracular (dorsoventral), diffu- 

 sed band with the margin of segment 2 green. L : 10 mm.: 4 ; B : 2 mm.; H : 

 3 mm. 



Pupa. — Is normal in xhapf. The head just appears beyond the straight, 

 never emarginate, front margin of segment 2 : showing the vertex and the 

 bases of the antennre, the frons being flat, high and broad, perpendicidar 

 to the longitudinal axis of the pupa. Segment 2 is squarish in front, 

 convex transversely with a gentle dorsal ascent to the thorax, the hinder 

 margin waved somewhat strongly forwards in the dorsal region ; the front 

 slope of the thorax is at an angle of rather more than 120" to that of 

 segment 2 and abmit 4o" to the longitudinal axis of the pupa, the hinder 

 slope very feeble, the hump not considerable or very convex, the slopes of 

 the sides to the slightly prominent shoulders very steep, the hinder margin 

 produced triangularly backwards, t^e apex of the triangle slightly 

 rounded, the line of margin meeting the wings in a. deep, broadlj' rounded 

 angle of somewhere about 4o' ; the body is somewhat compressed later- 

 ally about segments 4-<J so that the wings are there somewhat roundly 

 prominent ; the body is broadest at segment 8 though little broader 

 than at shoulders and the i)ortiou between is very slightly concave ;
