356 FAMILY XL — LYGJEIDJE. 



Y., in August on goldenrod, and Heidemann near Washington, 

 D. C, on the ripened fruit-heads of the sycamore. 



293 (474). Belonochilus koreshanus Van Duzee, 1909, 165. 



Elongate, slender. Grayish-brown; head, pronotum, scutellum and 

 under surface often reddish-brown or in part fuscous; fourth joint of 

 antenna? dark brown, the others paler; bucculas, median line of pronotum 

 and apical half of median carina of scutellum, pale yellow; membrane 

 whitish-hyaline often with vague dark brownish blotches and usually 

 with a reddish one each side of base; tibiae dull yellow, the base and apex 

 darker. Tylus longer and more slender than in numenius. Ocelli much 

 closer together, separated by slightly more than twice their diameters, in 

 numenius, much closer to eyes and separated by four times their diam- 

 eters. Median carina of scutellum narrower, less prominent. Other dif- 

 ferences as in key. Length, 4.8 — 5 mm. 



Sanford, Caxambus, R. P. Park, and Dunedin, Fla., Nov. 18 — 

 April 8. Taken in small numbers by beating water oak and 

 dead vines and sweeping vegetation near water. The types of 

 Van Duzee were from Ft. Myers and Estero, Fla., and at the 

 latter place he "found them abundant on a low branching hir- 

 sute, labiate plant ; locally called 'pennyroyal.' The flowers of 

 this plant form compact heads something like those of the 

 crimson clover, and among the bracts of these the insect oc- 

 curred by hundreds in all stages of growth." Barber records 

 koreshanus from five Florida localities other than those men- 

 tioned. So far as known it occurs only in the southern half of 

 that State. 



Subfamily II. CYMIN^E Stal, 1862a, 211. 



Small oval or elongate species differing from the Lygmncs 

 mainly in having the hind margin of pronotum each side of 

 base of scutellum not depressed or impressed ; corium with dis- 

 tinct punctures ; membrane without a cross-vein near base. The 

 front femora are not swollen or armed beneath ; and none of the 

 spiracles are visible on the ventral surface. The females re- 

 semble those of the tribe Orsillini in having the last three or 

 four ventral segments compressed, overlapping and inclined 

 forward. The subfamily comprises four North American 

 genera, three of which are represented in the eastern states.

a. Corium in great part hyaline, with only a few punctures along its 

 middle; fourth antennal subequal to or slightly longer than third; 

 head without a curved longitudinal sulcus before each ocellus; scu- 

 tellum equilateral (Tribe Ischnorrhynchini Stal).
