SUBFAMILY III. — BUSSING. 367 



third about two-thirds the length of second. Beak reaching base of pro- 

 sternum. Pronotum distinctly longer than wide at base, disk subdepressed 

 with a vague postmedian transverse impression, this and the area just 

 behind it rather coarsely punctate; side margins sinuate opposite this im- 

 pression, then broadly rounded to the post-apical constriction. Scutel- 

 lum with a distinct transverse basal ridge, the concavities behind it 

 each side of median carina sparsely, coarsely punctate. Elytra reaching 

 sixth dorsal. Female with fifth ventral as in rufipes. Length, 6 mm. 



Dunedin, Fla., Feb. 9 — March 22. Described from two fe- 

 males, one beaten from dead leaves of cabbage palmetto, the 

 other swept from weeds along a roadside ditch. Longer and 

 stouter than rufipes with longer pronotum and very different 

 color of corium and membrane. It is evidently closely allied 

 to the Brazilian /. tibialis Stal, which has a similar black spot on 

 membrane, but in that species the femora are black. 



308 (492). Ischnodemus lobatus Van Duzee, 1909, 169. 



Elongate, slender, subparallel. Black, clothed with a fine grayish 

 pubescence; basal half of antennae and legs pale reddish-brown; elytra 

 testaceous, the nervures of corium and veins of membrane darker. An- 

 tennae stout, basal joint short, oval, 2 and 4 subequal in length, the latter 

 distinctly the stoutest, fusiform, 3 two-thirds the length of 4. Beak al- 

 most reaching middle coxae, the second joint surpassing base of head by 

 half its length. Pronotum about one-third longer than wide, sides paral- 

 lel from base to apical third, thence strongly converging to apex; disk 

 with apical half convex, almost smooth, basal half strongly flattened, 

 rather thickly and finely punctate. Elytra, brachypterous form, reach- 

 ing middle of second dorsal, the membrane very small. Length, 5 — 6 mm. 



R. P. Park, Fla., Dec. 17. One brachypterous male swept from 

 herbage on margin of everglade. Recorded heretofore only from 

 Estero, Fla. 



309 (493). Ischnodemus slossoni Van Duzee, 1909a, 233. 



Elongate, slender. Above with head, apical two-thirds of pronotum 

 and scutellum black, sparsely clothed with prostrate grayish pubescence; 

 basal third of pronotum, veins of corium and membrane brown, or pice- 

 ous; abdomen blackish or dark brown, thickly clothed with minute sil- 

 very-gray pubescence; disk of corium and membrane white; under sur- 

 face black, legs pale reddish-brown. Antennae with joints 1 and 2 and 

 basal half of 3 pale; remainder piceous. Beak reaching middle of meso- 

 sternum. Pronotum oblong, convex in front of middle, sides parallel 

 from base to beyond middle, thence abruptly rounded and converging 

 toward apex; disk with a postmedian coarsely punctured transverse 

 impression, the area behind this pale. Scutellum almost smooth without 

 basal ridge, its carina evident but feeble. Elytra, brachypterous form, 

 reaching only to middle of second dorsal, in macropterous to apex of fifth 

 dorsal. Sixth ventral of female narrowed and prolonged obliquely for- 

 ward, its apex ending beneath fourth and shutting off the fifth from the 

 median line of abdomen. Length, 4.5 — 5.2 mm.
