This species, evidently introduced from Europe, has recently be- 

 come fully established in localities where it did not exist a few years 

 ago. In Maryland, on the edges of wheat fields, and in eastern 

 Massachusetts on grassy low grounds, it appears in swarms. About 

 ten years ago I first met with a few individuals near Baltimore, by 

 sweeping the grass, etc., about the edge of a wheat field ; since then 

 they have greatly multiplied, and large numbers may now be obtained 

 there and in similar localities elsewhere. In Cambridge, Mass., the 

 grass is sometimes crowded with them. Specimens from Connecticut, 

 kindly obtained for me by Mr. Edward Norton, have the antennae 

 yellow, and are a little more slender than usual. Both the short- 

 winged and the fully-winged varieties occur in all the localities known 

 to me. 



Nabidua Uhler. 



General form of Nabis, elongated, body subcylindrical. Head 

 long, subcylindrical, clavate in front including the eyes, behind the 

 eyes elongated into a neck, which is almost as-long as the face and 

 front; face blunt and broad, the tylus vertical, forming with the up- 

 per lobes a globose prominence, the upper lobes almost as broad as 

 the tylus, triangular at tip; inferior lobes much longer than the upper 

 ones, narrowed and extending to the tip of the tylus, very slightly 

 convex, bounded above by a deeply impressed line; tylus at base 

 connate with the clypeus; cranium between the eyes with a short, 

 deep, longitudinal groove, behind transversely impressed, behind this 

 an elevated hump as in the lieduviina; gula moderately swollen be- 

 neath the eyes, the middle line slightly grooved; rostrum moderately 

 curved, reaching to the posterior coxas, the basal joint stout, com- 

 pressed, extending to the anterior coxa, the apex superiorly produced
