cifter the initial effort of exclusion. The color at this period was 

 jMnkish, Avings and pronotum first appearing colorless, with expan- 

 sion later darkening to normal dark brown color. At nearly 7 : 55 

 the insect became active, grasping the petiole with its forelegs 

 and the nymph case with hind feet, withdrawing the abdomen from 

 the case and turning at right angles to the deserted skin. Mean- 

 while the elytra and wings were expanding rapidly enlarging at 

 base to full width and unrolling toward tip, the extreme tip being 

 the last to lose its pink color and to acquire the natural symmetry 

 of the adult elytron. At eight the elytra and -vdngs were fully 

 expanded and the pronotal expansion started and five minutes 

 later the wings were fully out in nearly natural position and the 

 pronotum partially expanded at base and tip, with a distinct con- 

 striction near the tip. At 8 :08 faint indication on spots on head 

 and base of pronotum could be seen, the coloration lying toward 

 the head end but the elytra at this time was entirely transparent. 

 At 8 : 10 the pronotum was nearly expanded, the base and tip 

 nearly normal, but deeply hollowed at the middle and the tip 

 reaching only to the tip of the abdomen, the following two minutes 

 marking the beginning of coloration of the base of the elytra, the 

 fui-ther extension of pronotum which is still constricted somewhat 

 midway and nearly colorless. At 8 : 15 the constriction of the 

 ])ronotum was nearly gone and a minute later entirely so, the 

 structure reaching its mature form and reaching nearly to the 

 tip of the elytra. At this time the elytra nearly covered the wings, 

 the latter at first drooping below, the elytra gradually drawing 

 up closer to the body and assuming the normal position at rest. 

 At 8 : 20 the coloring became more noticeable, the costa darkening 

 and the pronotum becoming a pinkish red, the eyes dark red and 

 all traces of the pronotal constriction are gone and thus the insect 

 is fully normal except in color; and at 8:22 it walked about quite 

 actively Avith apparently very free use of the legs which a few 

 ininutes earlier were flabby, helpless structures. The head has 

 become bluish white; the further change noted in. this specimen 

 concerned simply the color, which at about 10 had become dark 

 bi'own, the nearly normal hue for average specimens. 



The first indication of mating was July 28, on a tree in the 

 open with the male clinging to the back of the female but not on 

 center ; July 29. male and female were on same twig end to end. 

 but no evident coj^ulation ; August 31. many males noted resting 

 on females but none were seen in coition. The prenuptial atten- 

 tions are apparently quite extended and the males rest uniformly 

 on the side of the pronotum of the female, the feet of one side 

 closed beneath the border of the elytra of the female. Often two 

 males are seen attached to one female but seemingly oblivious of 

 each other. They have no attachment to the twig and the female 

 walks readily up or doAvn the twig. As they are almost invariably 

 accompanied by one or more attendant ants, the moving mass 

 presents a very grotesque appearance. Tn some instances three
