838 FAMILY XXIX. — MIRID^E. 



(Davis). About Dunedin it occurs in some numbers on the 

 foliage of the scurfy ericad, Xolisme fruticosa Michx., and other 

 shrubs in pine woods. Recorded from Crescent City and San- 

 ford, Fla. Ranges from New York west to North Dakota and 

 southwest to Florida. 



900 (1145a). Lopidea marginalis (Reuter), 1909, 72. 



Closely allied to instabile. Front of head with a black spot, some- 

 times in great part fuscous; elytra widely and obscurely fuscous; scu- 

 tellum and calli heavily tinged with fuscous; embolium pale yellow, 

 rarely bright red. Length, 6 — 6.5 mm. 



Willow River, Minn., Aug. 7 (Minn. Univ. Coll.) . Originally 

 described from Maryland as a variety of instabile. Raised to 

 specific rank by Knight on account of distinctions in the male 

 claspers. Recorded by him from Connecticut. Readily known 

 from other species of the subgenus by the pale embolium. 



901 (1147). Lopidea confluens (Say), 1832, 23; I, 343. 



Orange-red to dull orange-yellow; head with antenna?, tylus, beak, 

 base of vertex and two stripes on front, fuscous-black; pronotum vaguely, 

 scutellum, apical two-thirds of clavus and inner third of corium more or 

 less tinged with fuscous; narrow edge of embolium often yellowish trans- 

 lucent; membrane blackish-fuscous; legs fuscous-brown to blackish, the 

 coxa? pale; under surface orange-red, mesosternum and genital region 

 usually darker. Joint 1 of antennae cylindrical, about one-fifth shorter 

 than width of vertex; 2 linear, of nearly equal thickness throughout, 

 about three times the length of 1 ; 3 three-fifths the length of 2, nearly 

 twice as long as 4. Form longer, with sides more parallel than in our 

 other species except staphyleas and robinise. Length, 6.3 — 6.5 mm. 



Frequent throughout Indiana, June — August. Palos Park, 

 111., July 16 (Gerhard). Blowing Rock, N. Car., September 

 ( Brim ley). In Indiana it has been taken from the foliage of 

 C>(//rr(/;(.s-;horse gentian, Triostcimi perfoliatum'L.;axid other plants 

 along the margins of woods. The recorded range extends from 

 Quebec and New England west to Montana, Colorado and 

 Kansas, and southwest to Texas, but many of the older records 

 doubtless refer to species lately described by Knight. 



902 (— ). Lopidea lathyr^e Knight, 1923b, 66. 



Head, except cheeks, lora? and a vague spot on each side of vertex, 

 black; disk of pronotum fuscous-brown, the narrow front edge and side 

 margins red ; scutellum, clavus, membrane and inner half of apical two- 

 thirds of corium dark fuscous-brown; legs fuscous-brown, the tibiae black, 

 coxae and trochanters in great part dull yellow; under surface red, the 

 mesosternum and genital region fuscous. Joints 1 and 2 of antenna? 

 black, 1 as long as width of vertex; 2 cylindrical, three times as long as
