SUBFAMILY II. — NABIN^. 597 



of middle femora. Macropterous forms are said to have the 

 clavus, corium and membrane streaked with fuscous or brown- 

 ish. 



570 (823). Nabis annulatus Reuter, 1873, 86. 



Elongate, slender, subparallel. Dull straw-yellow; two narrow 

 stripes on head, some vague irregular lines on front lobe of pronotum, 

 five faint stripes on hind lobe, some elongate blotches on apical halves 

 of clavus and corium, the nervures of membrane and incisures of con- 

 nexivum, fuscous; extreme apex of corium blackish preceded usually by 

 a reddish tinge; joints 1 and 2 of antennas dull yellow, the former with 

 two faint rings and the latter with apex darker, 4 and 5 tinged with 

 fuscous ; beak, legs and under surface pale yellow, the femora annulate 

 near apex and the tibia? near base with a single brownish ring; sides of 

 sterna and basal half or more of abdomen with a brown stripe. Joint 1 of 

 antenna? much longer than head, about one-fourth shorter than 2 — 5, 

 which are subequal. Collar and hind lobe of pronotum densely and finely 

 punctate. Disk of scutellum with two small fovea?. Connexivum very 

 narrowly exposed, male; slightly more widely so, female. Length, 

 8 — 9.5 mm. 



Marion and Putnam counties, Ind., April 15 — Aug. 12. Swept 

 from foliage of weeds and shrubs growing only in alluvial soil 

 along the banks of streams. Ranges from Ontario and New 

 England west to Illinois ; not recorded south of New Jersey. 

 Van Duzee (1894, 183) noted it as occurring in numbers on 

 rank vegetation near Lancaster, N. Y. The annulate femora 

 and tibiae taken in connection with the densely punctured col- 

 lar and hind lobe of pronotum readily separate it from our other 

 species. In several of the specimens at hand there is a small 

 crimson spot each side of scutellum and another on third con- 

 nexival in addition to the vague one usually present in front 

 of apex of corium. 



571 (828). Nabis capsiformis Germar, 1837, 132. 



Elongate, slender. Pale straw-yellow, elytra shining without fuscous 

 spots other than the usual three dots ; head and front lobe of pronotum 

 tinged with fuscous, the latter with a narrow median stripe and some 

 irregular curved lines darker; membrane shining iridescent, its veins 

 dusky; hind lobe of pronotum with traces of five dusky stripes; under 

 surface pale dull yellow, the sides with a narrow brown stripe; middle of 

 mesosternum and usually of abdomen with a dark stripe; antenna? and 

 legs pale dull yellow, the front femora rarely with some small brown 

 dots ; tarsal claws blackish. Joint 1 of antenna? a little shorter than head, 

 2 and 3 subequal, each nearly one-half longer than 1, 4 shorter, half the 

 length of 2. Elytra surpassing abdomen by one-half the length of mem- 

 brane. Dorsum of abdomen pale tinged with reddish, male; fuscous, 

 female. Length, 8 — 9.5 mm.
