TRIBE I. — GALEATINI. 471 



with a single row of large cells each side; paranota narrow, 

 strongly reflexed and with a single row of cells ; pronotum tri- 

 carinate, the carina? nearly parallel, the median one usually 

 slightly the higher; elytra, macropterous form, much surpass- 

 ing the abdomen, the costal area with cells larger towards apex 

 than at base ; in brachypterous form, elytra about two-thirds 

 the length of macropterous, the pronotum much reduced and 

 flattened. The genus is represented by several species in 

 tropical America and by two in the eastern states.

432 ( — ). CORYTHAICA bellula Bueno, 1917a, 19. 



Elongate-oval. Body, legs, beak and antennae pale brownish-yellow, 

 tip of beak and tarsi blackish; upper surface dull grayish-white, the 

 nervures in great part dull yellow; carina of hood fuscous-brown. Hood 

 with basal portion broader, rounded behind and with two rows of cells, 

 its carina continuous with median one of pronotum. Antennae with 

 joints 1 and 2 shortest, 3 longest, 4 stouter, setose and subclavate. Elytra 

 in macropterous form oval, the costal margin broadly curved, strongly 

 reflexed, costal area with a single row of cells, subcostal area long, nar- 

 row, curved and with two or three irregular rows of cells; discoidal area 

 reaching apical third of elytra, narrowed at each end, its margins ele- 

 vated to form carina-like sutures with those of subcostal and sutural 

 areas. Brachypterous form oval, with cells of elytra much smal'er and 

 sutural area almost obsolete. Other characters as under generic head- 

 ing. Length, macropterous form, 2.2 mm.; brachypterous, 1.9 mm. 



White Plains, N. Y. (Gerhard). Known only from White 

 Plains, the type locality where, says Bueno (loc. cit.), "it oc- 

 curred only on a sloping grassy meadow going up from a rich 

 marshy swale in a field, among fine low grasses much inter- 

 mingled with moss." Here it was taken by sweeping close to 

 the ground, from April to September, but was most common 

 in June. Bueno states that the general color "ranges from a 

 light gray, nearly white, through darker gray and brownish to 

 nearly black." 



433 ( — ). CORYTHAICA FLORIDANA sp. nov. 



Elongate-oval or fusiform, strongly tapering both before and behind, 

 widest across middle of elytra. Above pale brown ; median carina of hood 

 and its cross veinules, cross veins of elytra and a distinct spot on apex 

 of each discoidal area fuscous; basal portion of pronotum, legs and an-
