Fifth instar (Plate XXVIII, fig. 5): Color pale yellowish green. Segments of 

 abdomen with a fairly regular pattern of roundish white blotches; a small one on front 

 and one on hind margin on median line; larger blotches on each side are arranged 

 alternately near the front and hind margins. Outer side of hind femur with numerous 

 black spots extending over the distal two-thirds or four-fifths. Antennae marked 

 similar to adult. Length 11 to 12 mm. Antennae 23 mm. 



Adult (Plate XXVIII, fig. 6): Moderately slender. Pronotum as broad as long. 

 Color very pale green. Top of head between eyes and antennae orange yellow; occipital

green. Forewings of male very broad. Antennae white, with gray annulations in 

 the outer part at intervals of about four segments. First segment is pale orange 

 yellow on all parts except the large swelling on the front and inner side which ia 

 white and has a conspicuous round black spot in the center. (Fig. 30, a.) The 

 second segment is white with a similar spot. Length to end of abdomen 14 mm. 

 Forewing of male 13-14 mm. x 6 mm. Forewing of female 12-13 mm. 



HATCHING OF EGGS AND TIME OF APPEARANCE OF NYMPHS. 



Before hatching, the egg becomes swollen, due to internal pressure. 

 The end of the cap then breaks off and the embryo slips out. When 

 it first appears the body is nearly perpendicular to the branch. 

 (Fig. 32, b.) It retains its embryonic form until several abdom- 

 inal segments have been exposed, then the head bends down and
