392 FAMILY XI. — LYG^ID^E. 



terms reddish-brown, the fourth joint and apex of third darker. Hind 

 lobe of pronotum about one-third the length and but slightly wider than 

 front one, its disk finely and rather closely punctate. Scutellum with 

 apical half finely transversely rugose, punctate at sides, vaguely cari- 

 nate. Elytra reaching middle of fifth dorsal. Length, 7.5 mm. 



Lakehurst, N. J., July 4 (Barber). Described from there 

 and recorded elsewhere only from Quebec. Beaten from small 

 pines, which were partly scorched from fire. 



IV. Ligyrocoris Stal, 1872b, 51. 



Elongate, rather robust species having the head porrect, 

 wider across eyes than front lobe of pronotum and without 

 distinct neck behind ; beak reaching middle coxae, its first joint 

 not reaching base of head, third nearly twice the length of 

 fourth ; bucculae very short, not reaching base of antennae, 

 sometimes wanting; antennae (in our eastern species) with 

 basal joint surpassing tip of tylus, fully or nearly as long as 

 basal joint of beak, third and fourth almost subequal in length, 

 second longest ; pronotum with front lobe narrower and less 

 than twice the length of hind one ; scutellum usually much 

 longer than wide at base ; elytra as wide as abdomen ; connex- 

 ivum net exposed ; front femora swollen and armed beneath, 

 usually on inner side only, with a few teeth of unequal length ; 

 basal segment of hind tarsi usually more than twice the length 

 of others united ; second and third ventrals strigose as stated 

 in key. 



In old or greasy specimens the primary character of a "de- 

 nuded densely and very delicately strigose vitta" each side of 

 second and third ventrals (fig. 70), is often very difficult 

 to see. In clean fresh ones it is plainly visible. More than 

 twenty species are known, eight of which occur in the eastern 

 states.

a. Corium without a transverse dark bar behind the middle, its nar- 

 row costal margin wholly pale. 

 b. Ventral lunate strigose area much obscured by a coating of fine 

 hairs; front and hind lobes of pronotum of nearly equal width; 

 outer basal angle and basal veins of membrane pale.

 the middle or much mottled with pale.
