2. T. discolor, new sp. 



Form of a narrow Nabis ; fuscous or rufo-fuscous, with the hemefytra, sides <i 

 pronotum, base of coxse and disk of venter pale testaceous. Head moderately 

 le, dull, dark fuscous or piceous including the eye-,, base ol antennas, an< 

 base of the rostrum ; vertex and face concurrently convex : eyes nearly globular, 

 prominent ; antennae somewhat longer than the body with the wing-covers, pale 

 rufous, a little dusky towards the tip, the basal joint stout, a little bent, rather shorter 

 than the pronotum, the second joint nearly as long as the clavus, the third much 

 iter, about as long as the basal ami longer than the fourth : rostrum reaching t> 

 the middle coxae, fuscous at base and piceous at tip. Pronotum campanulate, dull 

 fuscous, with two indistinct yellow spots behind the head, scabrous, more coarsel] 

 punctate on the posterior lobe, anterior lobe sub-cylindrical, plane above, almost as 

 long as the intermediate lobe, the Latter tumid, transversely Indented on the middle, 

 the posterior lobe a little longer, somewhat flattened, broadly and deeply indented 

 mi'Ii side next the middle lobe, with the lateral mar-ins more broadly rellexed, and 

 postero-lateral angles produced ; posterior maigin arcuated. Legs long, pale dull 

 rufous, darker on the knees and tarsi, paler at base of femora. Scutellum moderately 

 flat, dull piceous, with a smooth tubercle at tip. Hemelytra minutely pubescent, 

 ile testaceous, tinged a little with dusky upon the nervures and clavus, in pale spe 

 cimens the discal and inner portions are rosy ; membrane whitish, the nervure dusky. 

 Presternum and a broad, vitta each side extending along the sides to the tip of venter 

 fusco-rufous ; the edge of the connexicum ivory yellow. The red vitta} of the venter 

 are sometimes expanded so as to cover the sides and leave only the disk and margin- 

 testaceous. 



Length to tip of hemelytra 5|— 6, to end of venter 4', — 4), mm. Width of bas< 

 of pronotum 1 — i-\ mm. Q. 



Old and thoroughly matured specimens have the dark parts of the 

 pronotum and underside of the body black, and this causes the two yellow 

 spots behind the head to appear very distinct. Only females have thus 

 far been brought to notice. 



One specimen from near St. Louis, taken in May ; another from the 

 vicinity of Boston, and a third is in the National Museum at Washington, 

 which was captured near Garland, Colorado, on June 1 8th. 



Div. PHYTOCORARIA, Reuter.

 set closely into the thorax, and without the neck-like contraction behind the eyes. 

 Head short, nearly vertical, a little sloping forwards, with the eyes vertical, globoso- 

 ovate, occupying most of the side of the head, and curving upon the gula in the male, 

 a little less prominent in the female. Tylus almost vertical, a little curved beneath ■ 

 superior cheeks short, wide, blunt, tumid, inferior cheeks bluntly triangular. Vertex 

 [bngitudinally impressed. Antenna 1 cylindrical, stout, the two apical joints scarcely 

 thinner than the preceding one, basal joint a little thickened apically, the second as 

 long as from the front of the eyes to the base of the pronotum, third and fourth un- 

 nol quite as long as the second, the fourth shorter than the third, acuminate at 

 tip. Rostrum moderately stout, the basal joint thick, short, barely reaching upon
