mm. Body cylindrical, normal, joint 12 with a dorsal angled hump, 

 forming a low, subconical projection, joint 13 tapering a little, else 

 subequal, joint 2 smaller than the head. Segments coarsely 5 -annu- 

 late, annulet 2 the highest. Translucent whitish-green, the feet very 

 pale ; subdorsal line opaque, yellow, white on annulets i and 5 and 

 on its upper edge, widened dorsally on the segments to touch its fellow 

 on the third annulet on joints 6 to 11, widened laterally on joint 2, 

 but on the other segments straight on its lower edge. Three fine lat- 

 eral lines (lower subdorsal, lateral and suprastigmatal ), pale yellow, 

 straight, the upper in part confluent with the subdorsal on annulet i, 

 the three separated by equal spaces of the translucent ground color. 

 A broken, somewhat waved, narrow, pale, substigmatal line. Dorsal 

 geminate dots of dark red more or less distinct on joints 5 to 8, dorsad 

 of tubercle i on the slightly raised second annulet, a single spot on the 

 summit of the hump on joint 12. Tubercles invisible, seta^ minute, 

 the dorsal ones dusky. This is the palest form. In others the red 

 marks vary greatly. One had the dorsal spots large and single on 

 joints 3 to 10 and 12. The darkest forms have the head nearly white, 

 flushed with pink over the faces of the lobes; lines all yellow except 

 the edge of the subdorsal next to the red spots. There may be an in- 

 complete line of dark red between the subdorsal and lower subdorsal 

 lines ; dorsal dark red spots filling all the dorsum except for the sub- 

 dorsal line. Or the whole larva may be shaded with dark vinous red, 

 the color crossing the subdorsal line at annulet i and forming great 

 blotches over the sides. 



The larvae formed slight cocoons in the earth. The change to 

 pupa took place immediately, even in those individuals that did not 

 emerge till the following year. The pupa is cylindrical, rather elon- 

 gate and tapering slightly at both ends, smooth, rather light brown, 

 shining. The cases are shagreened, the wing veins showing rather 

 plainly ; abdominal segments lightly, uniformly punctured, the three 

 movable incisures finely granular. Cremaster a stout spine, termi- 

 nated in a number of irregular hooks Length 20 mm., width 6 mm.
