black, mottled with lighter. Antennae darker than before. Second seg- 

 ment with its surface granulated. Cervical shield dark brown, mottled 

 with lighter. A large, dull red area covers the dorsal surface of the 

 third segment behind its spines and the fourth and fifth segments, and 

 extends backward as a wedge-shaped elongation on the mid-dorsal line 

 on to the seventh segment. At the sides this area does not quite reach 

 the lateral horns, and a band between and around the second sub-dorsal 

 horns is yellow, as is also a pair of spots between the third sub-dorsal 

 horns. At the side of the area a triangular blue spot is wedged into 

 the area on a line between the second sub-dorsal and second lateral 

 horns like a similar spot lateral to the third sub-dorsal horn, while a 

 third blue spot, rather oval in outline, rests against the margin of 

 the red area as it begins to narrow posteriorly, just lateral to and in 

 front of the almost obsolete fourth sub-dorsal horn. 



In the seventh segment the end of the red area encloses a blue stripe, 

 lighter in the middle, extending into the tenth segment, where it is 

 enclosed by one corner of a rather triangular dull red area which covers 

 a part of the dorsum of that segment and all of the dorsum of the 

 eleventh nearly as far back as the bases of the ninth sub-dorsal horns, 

 and between which the area is slightly extended backward. Lateral 

 to the tenth sub-dorsal horns which arise from yellow areas, the dull 

 red extends backward somewhat, its outer margin in contact with three 

 dull blue spots. From the hinder end of the lateral extensions a faint 

 reddish band crosses the dorsum, completing the enclosure of the two 

 yellow areas from which the ninth sub-dorsal horns arise. These two 

 areas are separated from each other by a median blue spot on the 

 anterior portion of the eleventh segment, from which a blue line passses 

 backward crossed by the faint reddish band, and, in the area between 

 the ninth and tenth sub-dorsals, forms a large spot tinged slightly with 

 reddish. Extending from the blue spot in front of the fourth sub- 

 dorsal horn to that on the tenth segment is a narrow, creamy white 

 band margined on each side by an incomplete green line. A narrow 

 yellowish band extends from the second lateral horn nearly to the pos- 

 terior end of the body below the spiracles. Annulations of the body 

 well marked. Duration of instar, 5 or 6 days. 



Seventh Larval Instar. Length at rest, about 20 mm. ; in motion, 

 about 22 l / 2 mm.; greatest diameter, about n mm. Head less bilobed 

 than in the preceding instar. The red areas are darker and their out- 

 lines have changed somewhat, the anterior one beginning just behind 

 the first sub-dorsal horns and covering the entire dorsum from one row 

 of lateral horns to the other on the third, fourth and fifth segments, 

 except as noted below; narrowing on the sixth to lie between the sub- 

 dorsal horns of that segment, and narowing to a dorsal band on the 

 seventh and eighth segments. On the hinder part of the ninth segment 

 this band becomes somewhat broader, and on the tenth and eleventh
