758 FAMILY XXIX. — MIRID^E. 



780 (1013). Platylygus luridus (Reuter), 1909, 46. 



Pale brownish-yellow, the upper surface sub-glabrous, strongly 

 shining; collar and tip of scutellum dull yellow; elytra sub-translucent; 

 disk of scutellum, apex and inner half of cuneus, apical halves of femora 

 and ventrals often strongly tinged with reddish; membrane pale fuscous- 

 brown, veins yellowish. Joints 1 and 2 of antennae dull yellow, 1 sur- 

 passing tylus by half its length, 2 scarcely thinner and two and a half 

 times as long as 1 ; 3 and 4 fuscous, distinctly thinner than and together 

 about two-thirds the length of 2. Length, 6.5 — 7 mm. 



Ithaca, N. Y., July 13 (Minn, Univ. Coll.). Recorded only 

 from New Hampshire and New York. Occurs on white pine. 



XIX. Lygus Hahn, 1831, 147. 



Oblong- or elongate-oval, usually finely pubescent species 

 having the head porrect, inserted in thorax to eyes ; face ver- 

 tical, tylus prominent, higher than cheeks, its base on a line 

 between the bases of antennae; vertex, except in pabulinus, with 

 a basal carina in front of which there is usually a subtriangular 

 depression ; eyes prominent, oval, their inner margins concave ; 

 beak reaching onto hind coxae, rarely shorter (campestris) or 

 longer (approximates) ; antennae shorter than body, finely pubes- 

 cent, joint 1 shortest, 2 longest, usually slightly thickened on 

 apical half, 3 and 4 much more slender ; pronotum trapezoidal, 

 broader at base than long, collar distinct, hind portion moder- 

 ately convex, sides not margined, disk punctate except on calli 

 and the smooth elevated area in front of them ; scutellum equi- 

 lateral, slightly elevated above clavus; elytra entire, passing 

 tip of abdomen ; cuneus oblong-triangular, rather strongly de- 

 flexed ; tibiae armed with spines whose length equals or sur- 

 passes the thickness of the tibia ; first joint of hind tarsi very 

 little longer than second. The genus is a very large one, about 

 60 species being known from North America, 39 of which occur 

 in the eastern states. 



KEY TO EASTERN SPECIES OF GENUS LYGUS. 



a. Beak reaching fourth ventral; pronotum rather closely, finely and 

 shallowly punctate; collar and tip of scutellum white; male very 

 slender and nearly black. 781. approximate. 



(in. Beak not surpassing second ventral. 



b. Length of second antennal less than or scarcely equalling width of 

 head across eyes; basal carina of vertex very low; color yellow- 

 ish-brown to dark reddish-brown, darkened with fuscous. 



782. RUBICUNDUS. 

 bh. Length of second antennal greater than width of head.
