92 OIDARIA RETICULATA. 



gradually forward, though most from the third segment 

 to the head, which is very small and narrow, with the 

 mouth extended in front ; it tapers also just a little 

 towards the anal extremity; the second segment rather 

 short, the others moderately well defined and tolerably 

 plump, with the usual transverse wrinkles of the 

 genus just visible ; the colour of the head is very pale 

 watery-greenish, with a fleshy tinge, the thoracic seg- 

 ments (generally paler than the rest of the body) are 

 of a light warm pinkish yellow-green, and sometimes 

 the three, or four hinder segments are similar, while 

 those of the middle of the body are deeper coloured, 

 of rather stronger green inclining a little to slaty or 

 pinkish, or else much the same pinkish yellow-green 

 throughout, the sides often deeply tinged with pink ; 

 conspicuous on either side of the back is a whitish 

 or faint yellowish-white opaque subdorsal stripe, 

 the dorsal vessel of brownish-red continuous on the 

 thoracic segments shows obscurely through the skin 

 of the back as though deep below it, in some parts 

 pulsating between whitish threads, but at the seg- 

 mental divisions is strongly and clearly marked on the 

 skin as a spear-point, or thick elongate spot of dark 

 red, often prolonged on one or two of the hinder 

 segments ; the anterior margin of the anal legs is 

 pale primrose-yellow ; very fine brown trapezoidal dots 

 are sometimes noticeable on the back; on the belly 

 a central yellowish stripe ; the small flesh-coloured 

 spiracles are situated on the fine tracheal whitish 

 thread which shows distinctly through the clear skin ; 

 this assimilates well with the internal pale fibres which 

 show through the stem of its food-plant. 



The pupa is about seven-sixteenths of an inch in 

 length, of a plump figure, the wing-covers rather pro- 

 minently developed, their rays distinct, the abdomen 

 convexly tapering to a pointed tip, which is furnished 

 with two small converging spines ; the surface has 

 a fine punctate roughness, and the colour is light 

 ochreous-brown, rather shining. (William Buckler,
