796 FAMILY XXIX. — MIRID;£. 



of sides. Antennae dark brown, joint 1 one-fifth longer than width of 

 vertex; 2 cylindrical, four times as long as 1 ; 3 more slender, one-half 

 the length of 2; 4 three-fifths the length of 3. Length, 5 — 5.5 mm. 



Recorded only from Staten and Long Islands N. Y., where it 

 was taken by Davis in July and August. 



Subfamily III. ORTHOTYLIN^ Van Duzee, 1916a, 203. 



This subfamily comprises Mirids of very diverse form, size 

 and appearance, but all agreeing in having the arolia between 

 the tarsal claws distinct, erect, with tips converging (pi. X, 

 figs. 33 — 54), and pronotum without a distinct collar. The 

 membrane is glabrous, usually with two distinct cells ; cell of 

 inner wings without a hamus; tibiae narrowed toward apex, 

 usually distinctly spinose ; third tarsal joint longer than either 

 of the others. For convenience of study the subfamily is 

 divided into eight tribes. 



KEY TO TRIBES OF SUBFAMILY ORTHOTYLIX^E. 



a. Eyes pedunculate; head very broad. I. Labopini, p. 797. 



«o. Eyes not pedunculate; head not unusually broad. 



b. Flanks of pronotum separated from the disk by a distinct suture; 



hind portion of pronotal disk elevated or on a higher plane than 



and projected above the base of scutellum; upper surface thickly 



clothed with erect bristly pubescence. II. Semiini, p. 798. 



bb. Flanks of pronotum not separated from disk by a suture; base of 



pronotal disk not projecting above the scutellum. 



c. Body robust, short oval or ovate, often brachypterous ; hind femora 



thickened, saltatorial; head strongly vertical, the vertex, viewed 



from above, wider than length of head. III. Halticini, p. 799. 



cc. Body more elongate; hind femora normal; length of head (except 



in Pilophorini) usually greater than width of vertex. 



d. Slender ant-like species with broad head ; form usually elongate 



with body constricted at middle; pronotum with sides sulco- 



sinuate, the apical half of disk narrowed; elytra usually with 



narrow cross-bars of silvery deciduous scale-like hairs. 



IV. Pilophorini, p. 806. 

 dd. Form not ant-like; sides of pronotum not sulco-sinuate; elytra 

 devoid of silvery markings. 

 e. Joint 3 of antenna? as thick as joint 2, or nearly so; females 

 often brachypterous. 

 /. Pronotum not distinctly campanulate, its apex wider than 

 vertex; elytra not coarctate at middle; abdomen broad at 

 base. V. Ceratocapsini, p. 819. 



//. Pronotum campanulate, its apex scarcely wider than vertex; 

 form slender with elytra coarctate at middle ; abdomen nar- 

 rowed at base. VI. Systellonotini, p. 830. 

 ee. Joint 3 of antennae distinctly more slender than joint 2.
