TRIBE I. — GALEATINI. 463 



single transverse row of partially hyaline cells; these elytral spots often 

 vague, sometimes almost wholly obsolete. Hood compi-essed at middle, 

 its cells but slightly larger than those of paranota. Median pronotal 

 carina feebly arched and with two rows of cells. Spines along margins 

 short, numerous, close-set. Length, 3.2 — 3.4 mm. (PI. IV, fig. 6). 



Common in the southern half of Indiana, May 20 — Oct. 13 ; 

 not taken but doubtless occurs in the northern counties. Beat- 

 en from white oak and swept from asters, goldenrod and other 

 Composite. Dunedin, Fla., March 14 — April 27; swept from 

 herbage in low moist grounds. Recorded from Ft. Myers and 

 Lake Worth, Fla. Ranges from Ontario and New England 

 west to the Pacific, and southwest to Florida and New Mexico. 

 Known as the "chrysanthemum lace-bug," and breeds on rag- 

 weed, chrysanthemums and allied Compositse, often doing 

 much damage to the cultivated forms. Weiss and Lott (1924a) 

 state that in New Jersey it is very injurious to wild asters, 

 and the sea-side goldenrod, the eggs, up to 150 in number, be- 

 ing placed in the tissues or along the veins and midribs of the 

 under surface of the leaves. The young feed in colonies on the 

 lower surface and are often attended by an adult female. Hus- 

 sey (1922, 23) mentions it as: "By far the most abundant 

 Tingid in Michigan, ocurring in Berrien County in almost 

 unbelievable numbers on goldenrod, but rarely taken on other 

 plants." Parshley (1919, 20) describes a variety inform is from 

 Vernon, B. C, and Truro, Nova Scotia, which in his later key 

 (1923, 700) he separates from marmorata by its having "short- 

 er elytra, the discal elevations extending to middle," in mar- 

 morata not reaching middle. 



419 ( — ). Corythuca baccharidis Drake, 1922, 37. 



Elongate, subquadrate. Body dark reddish-brown or black, the 

 apical ventral segment paler; antennae and legs dull yellow; nervures 

 of hood and elytral elevations fuscous-brown, those of paranota and ely- 

 tra straw-yellow, cells hyaline ; elytra with fuscous spots which usually 

 are so merged as to form very indistinct basal and apical cross-bars. 

 Antennae with numerous very long hairs. Margins of paranota furnished 

 with a double row of spinules ; those of costal and basal margins of 

 elytra with a single row. Hood slightly broader than high, its areolae 

 much larger than those of paranota. Tumid elevations of elytra very 

 large, rounded. Length, 4 — 4.2 mm. 



Key West, R. P. Park, Ft. Myers and Dunedin, Fla., Nov. 23 

 — April 14. The most common Corythuca about Dunedin and 

 at the Park, where it occurs on the shrubby white-flowered
