subsist right through but, with tho growth, become dimmer with each 

 change ; in the end they are as often as not quite obsolescent, or even 

 wanting in the pure-green larvoe ; some larvte are much darker than others 

 because of the clothing of tubercles being denser and more pigmented. 



Pupa. — The shape is quite normal ; rather stout, stoutest at the abdomi- 

 nal segments 7/8; highest at thoracic apex; segment 6 ever so slightly convex 

 longitudinally. Head hidden, all except the smallest portion of the vertex, 

 under segment 2, the frons large and high in a plane at right angles to 

 the longitudinal axis of the pupa, the mouth-parts and clypeus ventral, 

 the autennse reaching the ends of wings and gradually broadened towards 

 the tips, the legs reaching only half way to the ends ; segment 2 large, about 

 one-third the length of thorax in the dorsal line, convex transversely 

 straight in the dorsal line ascending to thorax at an angle of oS" to 

 longitudinal axis, the front margin a more or less semi-circular curve from 

 shoulder to shoulder with the central part : the dorsal region say, between 

 the dorso.ateral lines more or less straight, perhaps a very little concave- 

 emarginate, the actual dorsal line with a very small, triangular emargination; 

 segment •"> or thorax humped-convex, somewhat ge.itly compressed 

 just above the shoulder with the shoulder only slightly prominent 

 and rounded, front slope rising in the same plane as that of 

 segment 2 : 35° to a point (it is all rounded) about half way towards the 

 hinder margin — perhaps a little less, the hinder slope gentle to the end of 

 segment 4, the hinder margin triangularly rounded and apex produced 

 into segment 4, meeting the wings in a broadly-rounded, rather deep 

 angle of about 70° ; segment 4, rather largely visible laterally, about half 

 segment 6 in length dorsally : segment 5 about half segment 6 in length — 

 or half segment 2 — -rising gently to middle of segment 6 but not reaching 

 the height of thoracic apex : segment 6-11 about coequal in length, the first 

 someA'hat convex longitudinally as well as transversely; abdomen stout, 

 stoutest at segment 7/8 which is the broadest part of the pupa ; the dorsal 

 line of abdomen thence to end is a quarter-of-a-circle-curve ; end herais- 

 pherically rounded, not as broad as segment 2 at extremity, the portion 

 composed of sej;ment3 12-14 dorsally perpendicular to longitudinal axis of 

 pupa ; segment 14 turned under somewhat, the suspensory hairs few and 

 quite ventral. Surface very minutely rugosely reticulate all over, even in- 

 cluding the wing-surfaces, the gland-scar on segment 11 evident; covered 

 all over with very minute, erect, light hairs, very short even under the lens ; 

 rather sparsely disposed, most numerous on the head, segment 2 and 

 dorsum of thorax ami there also slightly branched. Spiracles of segment 

 2 more or less Imear, slightly curved, situated along the curved hinder 

 margin of segment 2, raised, shining, extremely light-yellow in colour 

 and pitted coarsely — they are just like sausages cut in half longitudin- 

 ally ; the rest of the spiracles are slightly raised, broad, whitish ovals and 

 are rather small. The colour of the pupa is a light, soiled yellow with a 

 rosey tint except on the wings and head ; speckled brown all over ; a 

 cateniilated more or less dark-brown, dorsal band from end to end, some- 

 what broadened out on segment 2 ; a more broken, supraspiracular, similarly 

 coloured band widening out into black, triangular patches on the wing lino 

 at segment." 4 and 5 and on shoulders. L: 10 mm.; B: 4.5 mm.; H: 

 3*5 mm. 



HaJnts. — The egg is laid single on flowers, flower-stalks or in the 

 axils of the very young leaves ; the little egg-larva, eating its wa}' 

 out through the side, settles down in the axil of a rib or nerve of the 

 young leaf with the midrib and is not easy to see it is so small ;
