FAMILY XV. — TINGIDID^E. 



bars and discoidal area dark brown, the apical bar enclosing three large 

 hyaline cells. Hood abruptly compressed at middle, hind portion globose, 

 wider than long, its areolae large, more than twice the size of those of 

 paranota. Median pronotal carina arched in front and with a single 

 large basal cell, behind which are two rows of smaller ones. Costal area 

 of elytra broad, with three rows of large cells. Length, 4 — 4.2 mm. 



Southern half of Indiana, common, April 11 — Sept. 29; beat- 

 en from buckeye, 2Esculus glabra Willd., and sifted from beneath 

 dead leaves on wooded slopes. Dunedin, Fla., April 11 — 20; 

 beaten from horse-chestnut ; the first record for that State. 

 Henderson, Ky., April 29 (Marshall). Recorded only from Ohio, 

 Illinois and Kentucky, but probably occurs on various species 

 of JEsculus throughout their range. In color this species closely 

 resembles cydonice, but it is much larger and the hyaline cells 

 of the solid brown apical bar are three times as large as there.

Subquadrate. Body black, the apical ventral segment and margins 

 of prosternum pale; antennae and legs dull yellow; nervures of upper 

 surface pale brown, the cells of hood and paranota hyaline, or brown 

 with hyaline centers; pronotum, except tip, and 

 elytra, except space on costal area between the 

 basal and apical cross-bars, pale brown, the cross- 

 bars wide, their cells mostly brown with small 

 hyaline centers; the preapical bar with two or 

 three central cells wholly hyaline, as are also 

 those of the apical row. Hood longer than high, 

 compressed at middle, the bulbous hind portion 

 small, spherical, its cells but little larger than 

 those of paranota. Median pronotal carina low, 

 but feebly arched and with about six small areo- 

 lae. Tumid elevation of elytra prominent, round- 

 ed. Spines of margins very short. Length, 2.b 

 —3 mm. (Fig. 104).

(After Heidemann.. Washington, D. C, numerous stations in 



New York and New Jersey, and Clayton, Ga., June — October 

 (Daz'is) ; taken mostly on alder; one specimen, "Staten Island, 

 Feb. 26," by sifting. Ranges from Ontario and New England 

 west to Wisconsin and Kansas and south to Georgia. Recorded 

 also from Texas and California by Gibson (1918, 91), who 

 states that "the known food plants include hazel, elm, crab- 

 apple, black alder and sweet birch." 



425 (649). Corythuca juglandis (Fitch), 1856, 466. 



Subquadrate. Body wholly black; legs and antennae dull yellow; 

 nervures of upper surface thick, in great part yellow, those of crest of
