with a trace of vermillion within, under a lens; dorsal space filled 

 with dark red-hrown, of which a straight dorsal line is most distinct, 

 the glandular depressed spaces (i) appearing as large pale yellow dots; 

 outline of the dorsal space a waved line, the expansions between the 

 horns; upper half of lateral space dark red-brown, the edges a little 

 heavier and the centers shining slight pale spaces; region below dull 

 yellow, the row of lateral horns contrasting by its slightly lighter 

 shade. Horns strongly tubercular, the spines numerous, long and 

 black-tipped, but fine and inconspicuous. Later the vermillion in the 

 horns becomes more distinct, but the general effect is dull rusty 

 brown. The dark brown breaks through the subdorsal ridge between 

 the horns of joints 3 and 4 broadly and between 12 and 13 narrowly. 

 A narrow black line appears above the lateral horns. Length, 3.8 to 

 6 mm. Duration of the stage, 6 days. 



Stage \l. — Elongate, the ends rather rounded, dorsal and lateral 

 spaces moderate, subequal, subventcr retracted. Horns all subequal, 

 the subdorsals of joints 3 and 13 a little longer, also the lateral of 

 joint 3 longer and conical, the others subspherical. Dorsum purple 

 with elongate white patches on depressed spaces (i), dividing into 

 straight dorsal and wavy subdorsal purple lines; subdorsal ridge pale 

 yellow with central vermilion line, the horns vermilion tinted; horns 

 of joint 3 brownish red. Lateral space with pale patches over de- 

 pressed spaces (4), pale yellow below, leaving a purple line above 

 which is waved, and a central one which is straight; a livid purple 

 wavy line on each side of the subdorsal ridge; joints 3 and 4 solidly 

 purple shaded in the interspaces. Impressed glandular dots visible in 

 dorsal space. Skin rather densely granular shagreened. Length, 6 

 to 8.5 nmi. Duration of the stage 6 days. 



Stage Vn. — Elongate elliptical, dorsum gently arched, moderately 

 broad, sides oblique, subventer retracted. Horns of joint 3 and tht; 

 subdorsals of 13 slender, conical, rather long and dark vinous, the 

 others rounded, subspherical. vermilion, in a slender vermilion line 

 on the ridge. Surface pale opaque yellowish ; dorsal and lateral spaces 

 with three ])ur])lc brown lines, the center one straight, the side linc^ 

 waved; two similar lines in lateral space. Horns well spined (i) 

 and (4) glandular dots darkish. Skin granular shagreened. Clear 

 spaces on the upper sides of all the lateral horns with a few caltropcs. 

 the spaces above the subdorsal of 13 and lateral of 12 largest and
