SUBFAMILY II. — COREIN^E. 241 



rounded and acute behind ; beak with joint 1 stout, slightly 

 longer than head, 2 as long as 3 and 4 united, the third short- 

 est ; pronotum subhexagonal, the posterior side margin ill 

 defined, rounding into the subtruncate basal margin, humeri 

 rounded, not prominent, front side margins feebly sinuate, 

 entire, their edges reflexed; corium with veins prominent, the 

 median one forked ; membrane a little shorter than abdomen, 

 its veins numerous, mostly simple, a few forked ; connexivum 

 broadly exposed; hind femora thickened, subclavate, armed 

 beneath on apical half with two rows of short spines; sixth 

 ventral in female broadly and deeply emarginate, the basal 

 plates of genital segment very large, wholly covering the 

 median one ; genital plate of male scoop-shaped. 



Two species are known, one occurring in our territory, the 

 other in the southwestern states. 



173 (288). Chelinidea vittiger Uhler, 1863a, 366. 



Oblong-oval, depressed above, subeonvex beneath. Bright clay-yel- 

 low, glabrous; head, and antennae brownish-fuscous, the former with a 

 rather broad median yellowish stripe; front and basal margins of prono- 

 tum, scutellum usually and membrane, fuscous-brown or darker; elytra 

 dull yellow, thickly marked with fuscous punctures, the basal half of 

 costal margin and veins yellow; connexivum yellow, immaculate; under 

 surface uniform yellow; legs and joints 2 — 4 of beak blackish-brown, 

 basal joint of beak dusky yellow. Head with postocular spine reduced 

 to a blunt tubercle. Pronotum finely and densely granulate-punctate, 

 the humeral angles lower than the intervening parts and with a slight 

 tubercle within; disk somewhat uneven, the apex about one-half the 

 greatest width. Scutellum finely transversely wrinkled and granulate- 

 punctate. Elytra finely rather closely and evenly punctate. Front and 

 middle femora each with two or three short spines on the inner lower 

 margin near apex, and one or two on the outer. Length, 13 — 15 mm.; 

 width, 5 — 5.5 mm. 



Southern Pines, N. Car., September — December (Brimley). 

 Ranges in the east from Virginia southwest to Georgia and 

 Louisiana; in the west from Colorado and Texas to Arizona 

 and California. Recorded from Quebec by Provancher (1886, 

 55), but the single specimen taken was probably adventive. 

 Uhler (1872, 401) says that in Texas "it infests a species of 

 prickly-pear, Opuntia, sometimes in considerable numbers," and 

 it has been taken in Colorado and New Mexico from the same 

 plants. The color of the elytra varies considerably, due to the 

 greater or less density of the fuscous punctures. McAtee 

 (1919, 12) has given our eastern form a quadrinomial name, 

 viz., C. v. crquoris, var. artuatra.
