THE EGGPLANT LACE-BUG. O 



Pronotum feebly convex, black, with three low yellowish carinse, the median one 

 a Little higher before the middle, tapering toward the pale apex of the triangular 

 posterior portion of the pronotum; the lateral membranous part of the pronotum angu- 

 larly expanded, with two to five series of irregular areoles, the edge somewhat broadly 

 reflexed, some of the nervures exteriorly blackish. Head, pronotum, and the edge 

 of the membranous dilation densely covered with fine, soft hairs; pronotal hood 

 rather large, much longer than wide, covering the hind part of the head, leaving the 

 eyes free; surface yellowish white, opaque, with fine minute areoles. Hemeiytra 

 extending about one-third beyond abdomen; oblong-oval, broadly rounded at the 

 end, feebly sinuate toward the base; the discoidal areas pyriform, reaching to about 

 the middle of the elytra, reticulated, blackish at base and at apex, a pale stripe across 

 the middle, the subcostal biseriate, yellow; costal margin yellowish- white, translucent 

 with four or five series of medium-sized areoles at the widest part, those toward the 

 base smaller; five transverse oblique nervures black at the costal area and all nervures 

 at the apex more or less blackish. Legs pale, yellow. Length, 4 mm.; width, 2 mm. 



The following descriptions of the immature stages are by the 

 writer : 



THE EGG. 



Length 0.37 mm., width 0.18 mm. Color light to dark greenish at base, gradually 

 assuming brownish toward the apex. Top of egg crater-like, with whitish lacelike 

 border, and screwlike rim. The entire egg resembles a miniature bottle. The eggs 

 are attached to the underside of the leaves by their bases and usually lean in all 

 directions and at almost every angle. 



THE NYMPHAL STAGES. 



First stage. — Length 0.3 to 0.4 mm, width 0.12 mm. The newly hatched nymph 

 resembles a newly born aphis, is white to light yellow, with pink eyes, long legs, and 

 antennae as long as body. 



Second stage. — Length 0.8 mm., width 0.19 mm. Color yellow. Antennae as long 

 as body; the last segment clublike, covered with setae; last segment of the legs 

 possessing a pair of claws. There are spines on each side of the thorax and from each 

 segment of the abdomen. 



Third stage. — Length of body same as in the previous instar; width decidedly more, 

 0.30 mm. Spines on lateral margin and on dorsal surface of body. First indications 

 of wing pads occur in this stage by the swelling of lateral margins of the thorax. 



Fourth stage. — Length 1.5 mm., width 0.8 mm. Body oblong-ovate, yellowish. 

 Head dark yellow, hood prominent; wing pads extending to second abdominal seg- 

 ment. Entire body covered "with spines, the position of which is discussed in the 

 following nymphal stage. Antennae as long as body, light brown. 



Fifth stage.- — Length 2.2 mm., width 1.2 mm. (PL I, fig. 2.) Body oblong- 

 ovate, yellowish except at margin of abdomen, where it is light yellow with dark 

 patch at the apex. On the lateral margins of each side of first three abdominal seg- 

 ments a tubercle rises directly from the surface, and from the last six abdominal 

 segments rise prominent spiny processes. From the middle of each of first and second 

 abdominal segments there rise two hornlike spiny processes, and one from the fourth,, 

 fifth, and seventh segments dorsally. One spiny process and some tubercles on the 

 lateral margin of the wing pads; two large spiny processes placed near together on 

 the metanotum, and tubercles at each side of thorax. On each lateral margin of the 

 hood there is a spiny process and some tubercles; two prominent spines are located 

 centrally, and a small pair nearer the head. The head carries three strong spines in 

 front, one long and two shorter ones; two large, strongly curved, hornlike spines 

 at the base near the eyes. All spiny processes except on the lateral margins of the 

 sixth, seventh, and eighth abdominal segments dark brown; those on latter light 

 yellowish. Head yellowish brown; eyes prominent; thorax dark yellow; wing pads 

 light yellowish with dark margin at base, extending to fifth abdominal segment. 

 Antennae light brown, as long as body.
