When contracted it is about ten times as long as it is wide, and when extended still longer. The general color is green, brighter in the younger individuals and paler just before transformation. The head is prettily marked with purplish dots, leaving a white, longitudinal center through each half. The head is well divided, the two lobes meeting somewhat nar- rowly.

The head is prettily marked with purplish dots, leaving a white, longitudinal center through each half. The head is well divided, the two lobes meeting somewhat nar- rowly. The thoracic plate is of about the same width as the head, having a black border with conspicuous tuber- cles clothed witli rather long hairs. Of these tubercles there are two con- spicuous pairs on the first thoracic segment, with two others on each side. The second thoracic segment is very similarly marked. The abdominal segments are marked with four tubercles on the dorsum and larger ones each side. The arrangement of the spots on the anal segment is well shown in figure 1 at e. The location of all these tubercles is well illustrated in figure 1, the arrangement from above being shown at c and the lateral arrangement at h. The length of this larva when extended is about 20 mm. When at rest, or retracted, it is considerabl}'^ less. The width at the widest portion is about mm.
