INSECTS INJURIOUS TO GARDEN AND ORCHARD CROPS. 



STAGES OP NYMPH DESCRIBED. 



First stage (fig. G, d).— Immediately after batching, the nymph is clear 

 white with the bauds on the legs yellow, the antennae, eyes, aud the 

 spots on the body red. In a few minutes, however, these parts begin to 

 take on darker shades. A similar condition is observable also imme- 

 diately following the shedding of the other nymph skins. 



Just before the first molt the body is proportionately more rounded 

 and robust than in the adult, and the appendages, including the head, 

 are more prominent. The general color is clear white. The antennae 

 are a little longer than the body and considerably flattened, the penulti- 

 mate joint particularly so. They are finely hairy, very dark red in 

 color, and narrowly white at the sutures. The head is large, hexagonal, 



white, and the eyes are 

 red. The body is white, 

 widest about the middle 

 of the abdomen, the wing- 

 pads infuscated, and the 

 abdomen marked with red, 

 as shown in the dark shad- 

 ing in the illustration. The 

 legs are white and orna- 

 mented with infuscate 

 bands in the manner indi- 

 cated in the figure, which 

 sufficiently illustrates this 

 stage as to reuder further 

 unnecessary. 

 Length, about 2 mm . 



/Second stage (fig. 6, e). — 

 This stage very closely re- 

 sembles the first. The antennae, particularly the penultimate joint, 

 become still more prominent and the head grows darker in color. The 

 legs are banded with brown. Length, about 3 nmi . 



Third stage. — The third stage differs from the second principally in 

 the larger size of the body, which has assumed a pyriform shape, the 

 darker color of the body and bands on the legs, and in the greater 

 prominence of the tubercles at the sides of the body. The three tho- 

 racic segments are also more prominent, prolonged posteriorly, and 

 overlapping at the sides. Its sides are reflexed, strongly dentate and 

 denticulate. Connexivum also strongly dentate. Length, about 5" mi . 

 This stage is not illustrated. 



Fourth stage (fig. 6,/). — With this stage, as in tristis, the wing-pads 

 become evident, the thorax widens, the abdomen increases in girth, and 

 the third joint of the antenme decreases in width. The reflexion and 

 denticulation is still more pronounced. Length, about 7 miu . 



Fifth stage (fig. 6, g). — In the fifth or last stage this species more 

 closely resembles the mature form than is the case with tristis. This
