TRIBE I. — GALEATINI. 467 



hood fuscous, the cells subopaque; a small spot on paranota and basal 

 and apical cross-bars of elytra dark brown, the latter with two or three 

 large central areola? and part of the apical row whitish subopaque. Hood 

 one-half longer than high, strongly compressed at middle. Median 

 carina low, arched at base and with a large basal cell and a row of 

 small ones above. Tumid elevations of elytra relatively small. Length, 

 3.3—3.5 mm. 



Schooley's Mt., N. J., and Egg Harbor and West Point, N. Y., 

 May 20 — June 4 (Davis). Ranges from New England west to 

 Kansas and southwest to Texas. Not as yet identified from 

 Indiana, but doubtless occurs on its food plants, walnut, but- 

 ternut and linden, in many parts of the State. The smaller 

 size, paler brown cross-bars of elytra and whitish subopaque 

 cells distinguish it from contractu, its nearest ally. 



426 (645 1 /4). Corythuca contracta Osborn & Drake, 1916, 230. 

 Averaging larger than juglandis. Color much the same, last ventral 



brown at middle; median carina of pronotum with a dark curved cross- 

 bar at middle; cross-bars of elytra fuscous-brown, the apical one curved 

 forward from middle each side along the sutural area, cells of the space 

 between them clear hyaline, vitreous and much larger, with veins distinct- 

 ly thinner than in juglandis. Hood lower, its areolae more than three 

 times the size of those of paranota. Elytra somewhat tapering behind. 

 Spines of margins fewer and shorter than in juglandis. Length, 3.5 

 4 mm. 



Sherborn, Mass., Oct. 25 (Frost). Egg Harbor and Atlantic 

 and Cumberland counties, N. J., May — July (Weiss). Lake 

 Waccamaw, N. Car., April (Brimley). Ranges from New Eng- 

 land west to Illinois and southwest to North Carolina. Occurs 

 on walnut, pecan, butternut and linden. The C. parshleyi Gib. 

 (1918, 83) is a synonym. Drake (Ms.) states that contracta 

 is a synonym of juglandis, but numerous specimens received 

 from Weiss show them to differ as set forth above in key and 

 descriptions. 



427 ( — ). Corythuca exigua Drake, 1918, 83. 



Subquadrate. Body dark brown; under surface with a yellowish 

 tinge; antenna? and legs pale yellow; pronotum, nervures of hood, a 

 small submarginal spot on paranota, sutural area, two cross-bars and 

 hind portion of elevations of elytra, fuscous-brown ; nervures of para- 

 nota and pale areas of elytra white, the cells hyaline; apical cross-bar 

 with three or four large median cells, and those of terminal row just 

 behind them, hyaline. Hood about three times as long as high. Para- 

 nota very long, semi-elliptical, their margins with numerous short spines. 

 Median pronotal carina with two rows of cells, lateral carina? widely 

 separated from hood, each with two or three cells. Costal margin of 

 elytra straight, its spines numerous, very short. Length, 3.4 mm.
