468 FAMILY XV. — TINGIDID^E. 



Lake Waccamaw, N. Car., June 9 (Brimley). This is the 

 type and only known locality. 



428 (649 1 /4). Corythuca celtidis Osborn & Drake, 1916, 227. 



Oblong or subquadrate. Body black, the last ventral in part brown; 

 antennae and legs pale yellow, tarsi and fourth antennal slightly darker; 

 nervures of upper surface mostly white, those of paranota yellowish, 

 flecked with fuscous. Disk of pronotum dark brown, the posterior fourth 

 white. Elytra with two incomplete dark fuscous cross-bars, the basal 

 one interrupted, the apical one narrow and oblique, leaving the cells of 

 inner apical angles whitish subopaque, those of the space between the 

 bars clear hyaline. Hood nearly twice as long as high, about one-half 

 higher than median pronotal carina, the latter low, sinuous, not arched 

 and with a large basal cell in front of two rows of smaller ones. Length, 

 3.5—3.7 mm. 



Dearborn Co., Ind., Sept. 16; taken by scores on hackberry 

 (W.S.B.). New Brunswick, N. J., Aug. 10 (Weiss). Com- 

 munipaw, N. J., on Celtis, Aug. 8 (Davis). Ranges from Mary- 

 land and New Jersey west and south to Indiana and South 

 Carolina. Occurs on hackberry, Celtis occidentalis L. The low 

 unarched median carina and the white nervures and incom- 

 plete apical cross-bar of elytra distinguish this species from 

 juglandis and contractu. A var'ety, mississippiensis, which feeds 

 on the southern hackberry, Celtis mississippiensis Bosc, has been 

 named by Drake (1925, 36). It is somewhat larger (4 mm.) 

 with larger hood, more arched median carina and darker mark- 

 ings than the typical form, and is known from Tennessee, 

 South Carolina, Georgia and Mississippi. 



III. Stephanitis Stal, 1873, 119. 



Small oval species having the hood much as in Corythuca, but 

 less compressed in front and reaching back to middle of prono- 

 tum ; paranota widely and strongly reflexed ; median carina of 

 pronotum elevated, almost as high as hood, lateral carina? ab- 

 breviated ; margins and upper surface of paranota and elytra 

 without hairs or spines ; elytra gradually and widely expanded 

 from the base, their tips broadly rounded. One introduced 

 Japanese species occurs in the eastern states. 



429 (652). Stephanitis pyrioides Scott, 1874, 440. 



Elongate-oval. Body black; antenna? and legs pale yellow, the tarsi 

 fuscous; nervures of hood, disk of pronotum, except backward exten- 

 sion and an oblique spot on median carina, fuscous; elytra with a fus- 

 cous cross-bar at basal third and another at apical fourth, these con-
