596 FAMILY XX. — NABID^E. 



568 ( — ). Nabis constrictus Champion, 1899, 303. 



Elongate, slender, strongly constricted at middle. Dull straw-yellow; 

 head, front lobe of pronotum, a spot on humeral angles, a vague trans- 

 verse bar across the commissure of clavus, the tip of corium and the 

 veins and basal half of membrane, fuscous or tinged with fuscous; ner- 

 vures of apical half of corium and a spot on third connexival crimson; 

 connexivals with a small dark spot on each apical angle; under surface 

 with a narrow stripe along each side dark brown or fuscous; femora near 

 apex and the tibiae near base, each with a single brown ring. Eyes small, 

 prominent, coarsely granulated. Antenna? very slender, as long as body, 

 joints 2 — 4 subequal, 1 shorter, about as long as head. Elytra slightly 

 surpassing abdomen; connexivum rather widely exposed, female, wholly 

 concealed, male. Front and middle femora and tibiae with a few small 

 denticles in addition to the setae. Length, 6.5 — 7 mm. 



Lakeland, Fla., Feb. 22 ; two specimens beaten from bunches 

 of Spanish moss near the margins of a lake. Described from 

 Mexico, Guatemala and Panama and not before recorded from 

 this country. The small eyes, finely rugose hind lobe of prono- 

 tum, spotted connexivals, constricted elytra and crimson ner- 

 vures of apical half of corium distinguish it from annulatus, its 

 nearest ally. 



569 (824). Nabis spinicrus Reuter, 1890, 305. 



Brachypterous form — Elongate, subparallel, very slender. Dull red- 

 dish-brown to brownish-yellow, minutely and thickly pubescent; flanks 

 of front lobe of pronotum, five lines on hind lobe and a vague one on 

 elytra and along middle of dorsum fuscous ; under surface with sides of 

 sterna and ventrals fuscous; legs dull yellow, front and middle femora 

 faintly annulate with brown the ring near tips broader and more dis- 

 tinct; tibiae with a brown ring near base and apex; apical joint of tarsus 

 fuscous. Antennae very slender, joints 1 and 2 dull yellow, 3 and 4 and 

 apex of 2 fuscous-brown; 1 as long as head, 2 slightly longer and more 

 slender than 1, 3 and 4 subequal, each about one-third longer than 2. 

 Hind lobe and collar of pronotum minutely, rugosely punctate; elytra 

 very short, barely twice the length of scutellum, their tips obliquely 

 rounded and divaricate. Front femora with three or four widely sepa- 

 rated short, pale spine-like setae; middle femora with similar longer 

 blackish, white-tipped ones arising from fuscous dots. Genital plate of 

 male strongly convex at base, the apical half bent upward, broadly 

 rounded. Length, 6.3 — 6.7 mm. 



Dunedin, Fla., Nov. 27 — April 17. Seven brachypterous speci- 

 mens sifted from plant debris along the bay front and the 

 border of a pond. A neotropical species, known from the West 

 Indies and Mexico and recorded indefinitely by Van Duzee from 

 the "Southern States." It is our most slender-bodied species 

 and the only one with slender blackish spines on the under side
