dots, eoutrastccl with lavL^'cr spots of yellow tiiigecl ceutrally with a 

 rosy liue : for the rest I shall describe one full-grown larva, and men- 

 tion the variations of detail in the others, as each preserved its indi- 

 vidual points of difference to the last. 



The full-grown larva measured from three to three and a (quarter 

 inches in length, being in proportion a trifle more slender than f/alit\ 

 though otherwise similar in form, being plump and cylindrical, 

 tapering considerably from the fourth segment to the head, which is 

 the smallest segment, and is rounded in outline ; tapering a little also 

 at the two hinder segments, the twelfth having a rough, blunt-tipped 

 horn curving a little backw^ards ; each segment from the fifth to the 

 twelfth is subdivided into seven rings by well-defined wrinkles, the 

 front ring equal in width to three or four of the others ; the skin 

 generally smooth and shining ; the anal pair of legs larger than each 

 ^■entral pair, and of a squarish form ; the segments appear more plump 

 and swelling on the ventral than on the dorsal surface. As to colour, 

 two individuals were of the same type, the ground colour of the skin 

 only varying in intensity from a bronze-green to a deeper blackish- 

 bronze ; the head blood-red, the mouth and base of papillae pale yellow, 

 the former margined above and below, and the latter surrounded, with 

 black ; the dorsal stripe blood-red in colour, widened on the second 

 segment in a curve on either side downwards, suggestive of a plate, 

 but from thence continued of about uniform w'idth to the anal flap, 

 which is also red ; the horn is of the same colour, but with black tip, 

 and glistening ; in these larva) the sub-dorsal region bore a row of very 

 blunt wedge-shaped red marks, widest at the hinder part, and pointing 

 forwards, and a row of large roundish or dumpy pear-shaped bright 

 ochreous-yellow spots slightly tinged above with pink (on the twelfth 

 segment of a longer pear-shape, with the stem pointing to the horn), 

 and below these another such row only paler, and irregular in shape 

 from a fold in the skin, these spots on each front broad ring being 

 much surrounded with black; below these come a few small dots of 

 white, and then in its place — rather behind again — the whitish oval 

 spiracle; the hinder narrow rings of each segment — whether in the 

 red wedges or on the ground colour — bore transverse rows of thickly 

 set yellow dots: the puffed region below the Kpirncles showed red 

 interruptedly, but w ithout any dots ; beneath this again, a patch of the 

 dark ground colour, sprinkled with white dots ; the tips of the ventral 

 and anal legs blood-red; the anterior legs orange-ochreous tipped 

 with black.
