594 FAMILY XX. — NABID^E. 



corded south of New Jersey, except from Texas. Van Duzee 

 (1894, 182) states that about Buffalo, N. Y., it is "common 

 everywhere from July to September. The young in their earlier 

 stages quite strongly resemble our common black ants and may 

 be found in similar situations on goldenrod and other weeds 

 and bushes. They reach maturity about July 1, but here rarely 

 acquire wings." The long-winged form is everywhere scarce. 



565 (821). Nabis CRASSIPES Reuter, 1873, 83. 



Oblong-ovate, robust. Above dull clay-yellow; head between and 

 behind the eyes, a median stripe and some lines on front lobe of prono- 

 tum and numerous spots on elytra, fuscous ; scutellum black with a small 

 yellow spot each side; connexivals each with a blackish spot, the one on 

 sixth larger; pleura, meso- and metasterna and ventral surface of abdo- 

 men wholly or in great part fuscous-black; prosternum and apical lateral 

 angle of each ventral dull yellow; femora and tibiae with numerous dark 

 brown spots, the inner side of front and middle femora with dark cross- 

 bars; antenna? and tarsi dull brownish-yellow, the tarsal claws blackish. 

 Basal joint of antennae as long as anteocular part of head, 2 twice as 

 long as 1, 3 one-fourth shorter than 2, nearly one-half longer than 4. 

 Pronotum larger than in our other species, the transverse constrictions 

 vague; sides feebly sinuate and slightly gradually converging toward 

 apex which is about half the width of base. Elytra in macropterous form 

 but little surpassing tip of abdomen, in brachypterous one reaching only 

 to third dorsal with tips rounded and membrane obsolete. Front and 

 middle femora swollen, the former very strongly so, hind ones slender. 

 Length, 6 — 7 mm. 



Dunedin, Fla., Feb. 6 — 15 ; one beneath a board, another 

 swept from foliage in low ground. Borden Springs, Ala., 

 Aug 15 (W. S. B.). Tepehuanes, Mexico (Gerhard). Described 

 from that country and recorded elsewhere only from Georgia, 

 Texas and California. The tibise are dotted or in part streaked 

 with dark brown, not distinctly annulate as in sordidus or as 

 shown in the figure of Champion (1899, pi. 18).

 and tibia? dull yellow, the second antennal with an anteapical fuscous 

 ring and tibiae with four to six similar ones. Head shorter than prono- 

 tum. Joint 1 of antenna? one-third shorter than head. Pronotum nearly 

 as wide at base as long, the base twice the width of apex, hind lobe sub-
