Show 710 PROF. P. R. UHLER ON HEMIPTERA-HETEROPTERA [Nov. 2l, pubescent, with the veins thick and prominent, the costal margin almost straight, a little curved at tip ; membrane wide, with a large, closed cell at the inner angle from which two veins run curving towards the tip. BATHYDEMA SOCIA, sp. nov. Robust, blackish piceous, yellowish pubescent. Head tinged with brown, not polished, punctate above and below; antennae closely pubescent, pale fulvous or piceo-testaceous, with the basal joint darker above, and the thick apical joint fuscous, the apex of the second joint and base of the third sometimes with a narrow dark band; rostrum f ulvo-testaceous, hairy, piceous at base and tip. Pronotum dull blackish, coarsely punctate, the anterior lobe interruptedly margined with yellow, the posterior lobe feebly sinu-ated behind, with a testaceous arc next the humeri and a dot of the same colour on the middle of the margin, the lateral margin pale castaneous behind; pleurae dull piceous, punctate, pubescent, bordered with pale castaneous. Coxae pale castaneous ; legs yellow, tinged with fulvous. Scutellum dull fuscous, transversely convex at base, obsoletely punctate, pubescent, compressed and testaceous at tip. Corium and clavus testaceous, crossed in common by a dark brown broad band at tip, which includes two short yellow streaks and a dot; membrane brownish, with a pale dot at tip. Venter dull piceous. Length to tip of membrane 2 millim.; width of base of pronotum | mdlim. This interesting little insect approaches nearer to Peritrechus, Fieb., than to any other genus with which I a m acquainted. But the characters here given will, it seems to me, serve full well to separate it from that genus. Four specimens were secured on the Soufriere volcano, in April, distributed in the moss, at altitudes of 2000 and 3000 feet above sea-level. SPH^EROBIUS, gen. nov. Form similar to that of Herceus, Stal, but differs most conspicuously in having the anterior lobe of pronotum globose and as wide as the very short posterior lobe. The head is conico-ovoid, acute at tip, the tylus projecting prominently in front of the clypeus, with the two adjoining lobes of the cheeks short and feebly prominent ; eyes placed on or below the line of the vertex; basal joint of rostrum thick and shorter than the throat. Antennae moderately long, gradually thickening towards the tip, the basal joint much shorter than the head, the third joint a little shorter than the second, the apical joint longest and much thicker than the third; the bucculae short and restricted to the tip. Collum of the pronotum wide below, narrow above; the anterior lobe of the pronotum fully as wide as the very short, transverse posterior lobe, separated by a deep stricture, coarsely punctate, with the posterior margin sinuated and the humeral angles callous. Anterior femora very thick, fusiform, |
