SIXTH ANNUAL REPORT OF STATE ENTOMOLOIST 111 



Second stage (following first molt). Maximum length of body 

 13 mm. ; width of head 2 mm. Compared with hrst stage the general 

 color of the body is orange yellow instead of l>lack. The tubercles 

 are the same, except that instead of being glossy black they are dark 

 }'ellowish brown. Each segment has two black spots between each 

 two prominences of each segment, and there are similar dark spo:s 

 en the under side of the body. Head agreeing in color with the 

 tnbercles. A dark patch on the outside of each proleg. 



Third stage ( following second molt.) Maximum length of 

 body 22 mm.; width of head 25 mm. In this stage the insect dififers 

 ^•om the preceding in being yellowish green in color, in having the 

 head with a median sutural stripe, the clypeus, and a patch on each 

 side of the head, mellow. Tubercular prominences glossy black, 

 as in the first stage, relatively reduced in size. Tubercles of the 

 dorsal two rows, excepting the first segment, posterior to the head, 

 with a yellow spot on each side. 



Fourth stage (following third molt.) Maximum length 



^■^y mm.; width of head 3.25 mm. Head all yellowish green, excepi- 

 mg a small dot on each side of the front and a patch surrounding the 

 oeelli. General color of body yellowish green. Tubercles of dorsul 

 tvi'o rows as follows: on second and third segments those of the 

 dcrsal two rows are club-shaped and coral red with black spine^^, 

 while on the remaining posterior segments, to and including ths 

 twelfth, they are bright yellow with lateral black spots at the base. 

 The other rows, together with all tubercles on first and thirteenth 

 segments, blue. All spines black. 



Fifth stage (following fourth molt.) Maximum length 66 mm. ; 

 width of head 3.6 mm. In this stage the larva differs /-ery slightly 

 irom the preceding stage. The black spots in two's between the 

 tubercles are much reduced in size. 



Sixth stage (following the fifth molt.) Maximum length 

 So mm.; width of head 4.6 mm. Dififers from earlier stage in hav- 

 u'lg the median four prominences of first segment reduced to mere 

 tubercles which are a rich cobalt blue. Those of the second and 

 third segments in the dorsal two rows are larger, and are coral red 

 as in the earlier stage. Spines much reduced in relative size, 

 j^ateral tubercles cobalt blue at base and lighter apically. 



The foregoing descriptions were made from specimens reared 

 in the insectarv.
