840 FAMILY XXIX. — MIRID^E. 



antenna* equal to width of vertex, male, slightly longer, female; 2 three 

 and a half times the length of 1, its apical third very slightly tapering; 3 

 linear throughout, three-fourths the length of 2; 4 one-fourth as long as 

 3. Length, 6.5 — 6.8 mm. 



Marion and Floyd counties, Ind., May 31 — June 23 ; swept 

 from its host plant, the bladder-nut. Recorded from New York, 

 Maryland, Virginia and Michigan. Knight found it common 

 near Batavia, N. Y., the adults maturing July 18. Many of 

 them soon afterward left the host plant, congregating and 

 mating on nearby hickory trees. Hussey records it as very 

 common in late June on Staphylea in southwestern Michigan. 



905a ( — ). Lopidea STAPHYLE^E sanguinea Knight, 1917c, 461. 



"Size, structure of antennae and male genital claspers not differing 

 appreciably from typical staphyleie but the yellow coloration replaced by 

 bright red. Females much resembling those of reuteri and csesar, but 

 distinguished from them by the slender form of antennae." (Knight). 



Willow Springs, 111., Aug. 2 (Gerhard). Recorded from 

 Massachusetts, Connecticut and Minnesota. 



906 ( — ). Lopidea heidemanni Knight, 1917c, 456. 



Male — Dark red, antennae, tylus, front of head or two stripes there- 

 on and bar across calli, black or blackish-brown; scutellum, membrane, 

 legs, metasternum and genital region fuscous-brown; remainder of under 

 surface red. Joint 1 of antennae feebly curved, one-half longer than 

 width of vertex ; 2 three and one-half times the length of 1 ; 3 two-thirds 

 as long as 2, 4 one-fourth the length of 3. Elytra often slightly but visibly 

 tapering from base to apex, the clavus and corium usually with numerous 

 vague oblique rugae, very sparsely clothed with short fine yellowish-hairs; 

 costal margin with longer suberect blackish ones. Length, 6.7 — 7 mm. 

 Female — Slightly more robust than male, the elytra feebly broadly 

 curved from base to apex. Color somewhat paler, sometimes dull orange- 

 red, the dark cross-bar of pronotum rarely wanting; inner apical halves 

 of clavus and corium often lightly tinged with fuscous; embolium usually 

 wholly pale yellowish. Length, 6.2 — 6.5 mm. 



Marion and Putnam counties, Ind., June 1 — July 5 ; beaten 

 from elm (W.S.B.). Columbus, Ohio, July 12; Palos Park, 

 111., June 7 (Gerhard). Swannanoa, N. Car., June 22 (BrimJey). 

 The known range extends from New England west to Illinois 

 and southwest to North Carolina. Near Batavia, N. Y., Knight 

 found it breeding on elm, the nymphs feeding and maturing on 

 the tender terminal growth, usually of young trees. Other 

 nymphs were taken from yarrow, Achillea millefolium L., and 

 reared to maturity. The vertex of male is more concave, with 

 eyes more prominent and set more obliquely than in the female 

 or in any of our other species.
