red tips to the legs, and the caudal horn green at the 

 base, dark red next, yellowish in the middle, and red 

 at the tip. This was the fourth brood. 



After the second molt the first brood had yellow 

 granules, yellow face-lines, and the anal shield edged 

 with yellow. The horns were red at base and tip, yel-

 except on the thoracic segments, and gained the crest
