SUBFAMILY II. — CAPSIN^E. 689 



land west to Alberta and North Dakota. Very close to nigricollis 

 and may prove to be only a color variety of that species. 



II. Opistheuria Reuter, 1907a, 170. 



Elongate or subobovate, opaque impunctate species having 

 the head declivent, distinctly wider than collar of pronotum, 

 about as long as width across eyes, male, somewhat longer, 

 female; beak reaching middle coxae; antennae slender, as long 

 as body; pronotum slightly wider at base than long, apex 

 about one-half narrower than base, basal lobe feebly convex, 

 declivent towards apex, its hind margin with sides rounded and 

 middle subtruncate; elytra entire, surpassing abdomen, sides 

 parallel, distinctly dilated behind the middle, claval commis- 

 sure slightly longer than scutellum, cuneus longer than its 

 base, membrane with two cells ; legs pilose. Three species are 

 known, one from our territory. 



672 (913). Opistheuria clandestina Van Duzee, 1915, 110. 



Elongate, subparallel, male, obovate, female. Pronotum and ventral 

 surface, except genital segments, orange-red; head red with front and 

 tylus fuscous-black; scutellum and elytra fuscous-brown to black, the 

 side margins of the latter broadly pale; antennae and legs brownish- 

 black, coxa? reddish, basal halves of femora often in part dull yellow. 

 Joint 1 of antennae slightly longer than head, 2 one-half longer than 1, 

 3 two-thirds the length of 2, one-third longer than 4. Lorae separated 

 from the cheeks by a distinct suture. Collar prominent, longer than the 

 calli. Length, 7 — 7.5 mm. 



Harrison Co., Ind., Aug. 20. Sanford and Dunedin, Fla., Dec. 

 25 — April 10. At Dunedin both nymphs and adults were taken 

 in April by beating along the margins of wet hammocks. The 

 Indiana specimen has the base of pronotum clouded with black. 

 Described from Crescent City, Sanford and Ft. Myers, Fla. 

 Knight (1918b, 115; 1923, 550) has recorded the typical form 

 from New York and has named two color varieties, dorsalis 

 having the pronotal disk largely black and ventrals orange- 

 red, from New York and Ohio ; and ventralis with pronotum and 

 ventral surface chiefly black from New York and Wisconsin. 

 As the color, like that of a horse, varies greatly, these names 

 are superfluous. 



Tribe II. CAPSINI Reuter, 1883, 566. 



To this tribe, as characterized in the key, p. 681, belong the 

 great majority of North American Miridae of the subfamily
