II each, none on 12; on dorsum 01*3 one, two, or three similar patches, 

 but sometimes none; the rows of tubercles as before, but all are conical, 

 with hairs from apex and sides; the sub-dorsals on 3, 4, 5, 11, 12, 

 oranoe at base; the middle row black to base; the lower row orange 

 from apex to base; the double dorsal row of small spines as before, 

 but those on 3, 4, 5 are larger in proportion, the rest minute; on 2 is 

 a black chitinous collar and a compressed ridge in front; this ridge is 

 whitish, in the middle black, and at each end is a large spine in line 

 with the middle row; back of and between these on same segment a 

 smaller pair (in sub-dorsal row); head rounded, bilobed, black, shin- 

 ing, in front face a whitish chevron; surface beset with short black 

 hairs. Duration of this stage three days. 



After second Moult: length .3 inch, same shape; color black; the 

 white patch on 7 and 8 as before, variable in same way; so the spots on 

 10, II and 3; the tubercles as before, the orange at base reddish; some 

 larvae have the middle row orange, but usually it is black; the anterior 

 spines of the two mid-dorsal rows now conspicuous, largest on 4; the 

 other rows either minute or on last segments almost suppressed; head 

 shaped and colored as before, with similar mark in front face. Dura- 

 tion of this stage about three days. 



After third Moult: length .54 inch; same shape; color deep brown- 

 black; the patch on 7 and 8 much broken up, and usually restricted to 

 upper part of sides; on 7 sometimes a bar covering last ridge on dor- 

 sum; on 8 dorsum mottled black and white; on 11 and 12 each a small 

 round spot in front of and just below the tubercle of middle row; 

 sometimes an additional spot in line with these back of the tubercle; a 

 small patch on 3, sometimes bisected by the medio-dorsal line, and a 

 small spot on side of 2; over shield on 13 a white cross-bar; over feet 

 and legs each a white patch, and a smaller one on each intervening 

 segment; some examples have two small spots on dorsum and one on 

 side of 6; but others have no white spots on either anterior or poste- 

 rior segments, very little white on 7 and 8, and no white along base 

 (one had white over legs on 7 and 8 only); the ridge of 2 either wdiitish 

 or yellow; the sub-dorsal tubercles yolk-red at base except behind, where 

 the color is black, but on 7 and 8 the bases are yellow; the tubercles 

 of middle row are large on anterior segments, the rest small, and all 

 have red at base on dorsal side only; those of lower row are minute 

 except the anterior ones, and all are red to base; the tubercles of the 

 dorsal rows are mere points except on 3, 4, 5, and those on 4 are twice 

 the size of the others; head as before with whitish mark in front and a 

 white patch on side cheek. 



At 24 hours later: length .6 to .64 inch; the bases of upper two tu- 

 bercles on 7 and 8 light yellow; the chevron on face yellow, though the 

 cheek mark is white; before end of the stage the length was .7 at rest. 

 To next moult four days.
