cc. Sides of front half of pronotum near apex with a narrow acute 

 margin; transverse impression near front margin of pronotum 

 distinct, placed before the apical angles; front femora long,

I. Lyctocoris Hahn, 1835, 19. 



Oblong or oblong-oval, usually subopaque almost glabrous 

 species having the head about as long as the middle of prono- 

 tum, tylus stout, its apex truncate, eyes large, placed close to 

 base of head ; pronotum with sides margined from near base to 

 apex, the margins refiexed, front angles rounded, not deflexed, 

 hind margin widely sinuate; elytra entire, reaching apex of 

 abdomen ; front coxae short, subcontiguous ; front femora elon- 

 gate, fusiform, but slightly swollen, unarmed ; osteolar channel 

 nearly straight, joining at a sharp right angle a very fine 

 carina which extends to front margin of metasternal plate. 

 Males with a short spongy fossa at apex. Three of the five 

 known species occur in our territory. 



KEY TO EASTERN SPECIES OF LYCTOCORIS. 



a. Membrane with but one distinct vein; beak reaching middle coxae, 

 its first joint scarcely surpassing base of eyes. 596. CAMPESTRis. 

 aa. Membrane with four distinct veins; beak reaching hind coxa?, its 

 first joint as long as or longer than head. 

 b. First joint of beak about as long as head; second joint of antenna? 

 one-fifth longer than width of head across eyes. 597. STALII. 



bb. First joint of beak reaching onto prosternum; second joint of an- 

 tennas three-fifths longer than width of head across eyes.

 cius), 1794, 75. 

 Oblong-oval. Dark reddish to fuscous- 

 brown; second joint of antennae, except apex, 

 elytra in great part and legs pale brownish- 

 yellow; cuneus, apex of clavus and corium 

 and a spot on each connexival fuscous or 

 dusky; membrane hyaline with a dusky tinge. 

 Head subequal in length to width across 

 eyes, stouter and less prolonged in front of 

 eyes than in our other two species. Joint 1 

 of antennae scarcely reaching tip of tylus, 2 

 as long as head, 3 and 4 very slender, sub- 

 equal in length. Other characters as above 

 given. Length, 3.5 — 3.8 mm. (Fig. 157).
