 from Virginia southwest to Alabama and Mississippi. Nothing 

 has been published regarding its food 

 plants. 



X. Acanthocheila Stal, 1860, 61. 



Elongate-oval Tingids, readily distin- 

 guished from others of the tribe by the 

 single percurrent pronotal carina, which 

 extends from apex of the small hood to the 

 subtruncate tip of pronotum, and by the 

 long curved marginal processes or spines 

 of paranota; head without spines; elytra 

 rather strongly dilated, about twice the 

 length of abdomen, the usual areas flat- 

 tened and but feebly differentiated, the 

 <A EnT discoidal area not passing middle, its cells 

 much smaller than those of sutural and 



subcostal ones; paranota narrow, with a single row of cells. 



Two or three species are known from Central and South 



America and one from Florida. 



445 (664). Acanthocheila exquisita Uhler, 1889, 143. 



Broadly oval. Head with a white carina adjoining eyes each side of 

 vertex; tylus, bucculae and beak dull yellow; pronotum either ochreous 

 or blackish with ochreous veins, median carina whitish; elytra dull 

 grayish-yellow; under surface black; legs testaceous. Antennae testa- 

 ceous ; joint 1 thicker, shorter than head ; 2 almost as thick, bristly, sub- 

 conical; 3 much longer than the others united, slender, set with erect 

 slender hairs; 4 fusiform, longer than 1 and 2 united, bristly with apical 

 half blackish. Paranota with a single row of five quadrangular cells, 

 outer margin armed with six or seven long acute black-tipped spines. 

 Hind lobe of pronotum trapezoidal, its tip whitish, subacute. Clavus and 

 base of corium coriaceous, remainder of elytra subhyaline, cells of corium 

 increasing in size toward apex, the greatest width with six rows. Costal 

 margin armed with about 17 spines, these diminishing in length from 

 base to beyond middle. Veins of upper surface set with minute bristles. 

 Length, 3 — 3.5 mm. 



Originally described from four specimens taken in May at 

 Cape Florida, Fla., and not recorded elsewhere. The single 

 male is "more transparent and has more clean-cut black mark- 

 ings than any of the females" (Uhler).
