 1. Aradus apicalis, new species 



Allied to duzeei Bergr. ; blackish fuscous, a mark on the ex- 

 panded base of the elytra partially covering the base of the 

 mesocorium, the apex of the scutellum, and the incisures of the 

 connexivum pale or yellowish; antennae stout, black. Length 

 7 mm. 



Female: Head as long as the width across the eyes; vertex with the 

 longitudinal depression broad, armed with a prominent tubercle anterior 

 to the eye. Antennae stout, scarcely shorter than the head and pronotum 

 together; first segment obtuse-conical, scarcely longer than the apical 

 thickness of II, dull castaneous at base; II and III cylindrical, as thick 

 as the cephalic protuberance, II somewhat narrower at base; III three 

 fifths the length of II; IV oblong, two thirds the length of III, its tip 

 conical and clothed with pale hairs as in allied species. Rostrum pale, 

 attaining the basal third of mesostemum. Pronotum a little shorter than 

 the head, its width somewhat more than twice its length ; greatest width at 

 basal one third, sides less expanded than in duzeei, latero-anterior margins 

 nearly straight, coarsely and closely crenulated as in duzeei, discal carinae 

 as in duzeei, the median pair percurrent and but very little divergent 

 posteriorly. Scutellum longer and narrower than in any allied species, 

 one third longer than its basal width, the sides of the depressed apical 

 portion rectilinear, apex obtuse. Elytra narrower than in duzeei, membrane 

 touched with pale along basal margin, obscurely dotted. Legs, including
