Show 248 MESSRS. MOORE, WALKER, AND SMITH [Mar. 7> some irregular and indistinct pale brownish bands formed by clouded veins. Hind wings pellucid, cinereous about the tips; a tawny costal streak ; veins pale yellow, black towards the tips. Length of the body 10 lines; expansion of the fore wings 20 lines. Very closely allied to C. inamcenus. The keel of the prothorax is more strongly defined than that of C. signatipes. 6. CALOPTINUS INAMCENUS, Walker, n. sp. Male. Piceous. Head short; vertex with two slender furrows between the eyes; tip flat, subrhomboidal; front punctured, erect, with four distinct keels; inner keels slightly diverging from the vertex to the face ; outer keels nearly parallel. Antennae tawny, as long as the head and the prothorax together. Prothorax with a slight keel, with the usual four transverse impressed lines, and with two colli on each side; fore border hardly rounded; hind border slightly elongated and angular. Pectus and abdomen testaceous, the latter piceous above towards the base. Prosternal spine long and stout, rounded at the tip. Hind femora with three black spots on the upperside, and with a black stripe beneath. Hind tibiae red, their spines with black tips. Fore wings cinereous, brownish towards the tips, with several indistinct and irregular bands formed by brownish-clouded veins ; costa rounded near the base. Hind wings cinereous; a ferruginous costal streak; veins black, greenish white at the base and along the interior border. Length of the body 12 lines ; expansion of the fore wings 22 lines. The vertex between the eyes is narrower than that of C. brunneus. Order HYMENOPTERA. 1. VESPA BELLONA, Smith, n. sp. (Plate XVIII. fig. 6.) Female. Head, thorax, and legs pale yellowish brown; the eyes dark fuscous; the teeth and inner margin of the mandibles black; the flagellum of the antennae fuscous above towards the apex ; a fuscous spot in front of the intermediate and posterior coxae; the prothorax with a black transverse spot above; the wings fusco-hyaline, darkest at the anterior margin of the superior pair and towards their base. Abdomen black, with a narrow yellow marginal hand on each segment at its apex ; the apical segment entirely black ; the extreme base of the abdomen with indistinct yellowish stains. Length 1 inch 6 lines. Worker. Closely resembles the female; but in the single example received the abdomen has only a yellow margin to the basal segment ; all the tarsi are fuscous, with the claw-joint yellowish ; the flagellum is not fuscous above. Length 10 lines. This species is nearly allied to Vespa magnifica. The head of the female is widened towards the thorax, as in that species, and is deeply emarginate behind; the clypeus and mandibles are not so strongly punctured, and the apical segment of the abdomen is not yellow as in V. magnifica. Vespa basalis resembles this species, but |
