FAMILY XX. — NABID^. 



Fig. 147. X 6. (After Bruner). 



length of 1, 3 — 5 subequal, shorter than in pallipes. Pronotum as there, 

 its erect hairs more numerous. Elytra in macropterous form reaching 

 tip of abdomen, the large membrane with three elongate cells; in brachyp- 

 terous form only to second dorsal with membrane wholly absent, or to 



slightly beyond middle of abdomen, 

 the membrane then very short. Front 

 femora strongly swollen, armed be- 

 neath with numerous short setae. 

 Length, 5 — 7 mm. (Fig. 147). 



Marion, Vigo and Orange coun- 

 ties, Ind., Sept. 9— Oct. 18. Taken 

 while running over low sandy- 

 cultivated ground or beneath logs 

 and stones. Of the five speci- 

 mens at hand but one is fully 

 macropterous, two have the 

 elytra reaching middle of abdo- 

 men, the other only to second 

 dorsal. Its known range in this 

 country extends from New Eng- 

 land west to British Columbia. 

 Champion records it from Mexico, Central America, Panama 

 and Guatemala, but these records may be in error as it was 

 originally described from Pennsylvania, and as nitida Stal, a 

 synonym, from Wisconsin. There are no records in this coun- 

 try south of New Jersey. Except that it is found under logs 

 and stones, nothing has been recorded of its habits. 



Subfamily II. NABIj>L<E Reuter, 1890, 293. 



Elongate or oblong-oval, slender bodied species having the 

 head stout, subcylindrical, subporrect, the eyes placed near its 

 middle, some distance in front of pronotum, and ocelli on mid- 

 dle of postocular portion ; pronotum with two distinct trans- 

 verse constrictions, the collar wide; antennae 4-jointed; elytra, 

 except veins, largely membranous, the commissure in macrop- 

 terous forms much longer than scutellum ; front femora rarely 

 much swollen, the setae of their under surface fine ; front tibiae 

 but slightly wider near apex, their spongy fossa rudimentary. 

 Two genera represent the subfamily in the eastern states.

/>. Ocelli separated by at least their own diameters; first joint of an- 

 tenna? but little if at all longer than head; second joint of beak 

 but little longer than third. I. Nabis, p. 591.
