Reduviide. 165 
NABIS, Latr. 
A. genus of pale ochreous, brown, or in one continental 
species, green insects, of which we have ten in this country 
out of the twenty recorded as Palearctic by Puton. All 
our species occur on or amongst low-growing plants, except 
brevipennis, which is found on nut bushes. 
Head with the eyes large, more or less remote from the 
anterior margin of the pronotum; ocelli situated slightly 
behind the eyes, one on each side of the central dorsal line ; 
antenniferous tubercles not prominent ; antenna filiform, 
five-jointed, reckoning the very short joint which follows 
the first ; rostrum slender, reaching to the first or second 
pair of coxee ; pronotum elongate, constricted into a narrow 
simple collar in front, considerably widened posteriorly ; 
sides nearly straight; scutellam simple, or depressed at 
the base; elytra often undeveloped, in some species almost 
always so, consisting in macropterous specimens of corium, 
clavus, and membrane, the last having two large cells at 
the base; in brachypterous individuals these cells are 
wanting, or the whole membrane may be absent, and the 
corium much shortened and truncate; abdomen with the 
connexivum generally more or less dilated ; terminal genital 
segment in the male beneath very large, styles visible from 
above, and often affording specific characters ; in the female 
two segments are visible above, and the ovipositor can be 
seen beneath; legs moderately long, anterior femora 
slightly incrassated, intermediate tibiz denticulate along 
their inner margin, tarsi three-jointed. 
(6) 1. Connexivum more or less reflexed, not 
separated beneath from the central 
portion of the abdomen (Subg. 
Aptus, Stal.).

yellow spots.
