2, 4 one-third the length of 3. Front of head vaguely transversely striate. 

 Mesoscutum narrowly exposed. Abdomen reaching - tip of cuneus. Length,

St. Anthony Park, Minn., and Brookings, S. Dak., June 25

 Dakotas and Colorado. Taken mainly at light in July and 

 August. Host plant unknown. 



Subfamily IV. BRYOCORIN/E Douglas & Scott, 1865, 28, 276. 



Small oval or oblong-oval, shining species having the head 

 short, inserted in thorax to eyes, its front vertical or nearly so, 

 vertex without a basal margin ; antennae slender, filiform, near- 

 ly as long as body, separated at base by a distance less than 

 width of vertex ; pronotum trapezoidal or subcampanulate, con- 

 stricted at apical third, usually without a collar, disk punc- 

 tate, hind portion convex, often strongly so ; scutellum small, 

 triangular, much shorter than the commissure ; elytra usually 

 entire, clavus strongly deflexed toward corium, membrane one- 

 celled ; hind femora short, not swollen ; tibia? without spines. 

 Other characters as in subfamily key, p. 663. 



Our species are few in number, but often abundant in in- 

 dividuals. They occur, for the most part, on ferns growing in 

 wet places (whence the subfamily name) or on herbage in 

 dense woodland. Representatives of six North American gen- 

 era are known from the eastern states.
