THE CANADIAN ENTOMOLOGIST. 



ending in a flattened tubercle, the outermost (humeral) ridges very 

 short, nodiform. Scutellum threo-fourths longer than pronotum 

 in the middle, with a transverse tubercle before the middle, lateral 

 margins broadly and slightly rounded. Hemelytra (cf) reaching 

 the apical lobes of the abdomen, roundedly dilated and reflected 

 near jjase, exocorium and endocorium with some transverse ridges, 

 mesocorium with a single oblique transverse ridge behind the middle. 

 Abdomen three times broader than the membrane, apical angles of 

 fifth segment very slightly obtusely prominent, male genital lobes 

 obliquely slightly rounded at apex, meeting interiorly. Length, 

 d^ 5.8 mm. 



North Carolina (Southern Pines: A. H. Manse). — Coll. de 

 la Torre Bueno. A very distinct species, somewhat allied to the 

 quite differently coloured A. behrensi Bergr., but more broadly 

 ovate with longer and less incrassate antennae and much shorter 

 pronotum having the two median keels much more approximate at 

 base. I have not seen the female, but the abdomen is probably not 

 or not much broader in this sex. A. cincticornis Bergr. and 

 curticollis Bergr. belong to the very few Aradus species having the 

 abdomen broadly ovate also in the male. 



4. Aradus cincticornis Bergr. — This species stands in some 

 collections under the unpublished name A. nasuttis Uhl. 



5. Aradus tuberculifer Kirby. — Black, sometimes tinged with 

 greyish brown, apical margin of connexival segments 'yellowish, 

 corium with a dark luteous costal patch before the middle, this 

 patch being sometimes diffused over a large part of the corium, 

 legs fuscous black. Head distinctly longer than broad with a 

 U-shaped impression above, intraocular tubercle distinct, an- 

 tenniferous spines a little divergent with a small tooth, sometimes 

 indistinct or wanting, on the outer margin, rostrum reaching or 

 slightly passing the anterior margin of the mesosternum, second 

 joint of antennae a little shorter than the head, almost linear from 

 the base to the middle, then strongly and rather suddenly clavately 

 incrassate, third joint a little shorter than half the length of the 

 second joint, incrassate, even thicker than the apex of the second 

 joint, parallel-sided except at the constricted base, fourth joint 

 distinctly shorter and a little thinner than the third. Pronotum 

 two and one-half times broader than long in the middle, lateral 

 margins very finely crenulate or almost smooth, antero-lateral 

 margins slightly sinuate, the four median discal keels parallel, 

 the inner ones approximated in their anterior half, the outer ones 

 abbreviated before the middle; the greatest width of the pronotum 

 is immediately behind the middle, from which point the lateral 

 margins are very distinctly convergent towards the base. Scutel- 

 lum subtriangular, a little longer than the pronotum in the middle, 

 with a blunt median tubercle. Hemelytra ( 9 ) passing the base of
