Show 928 MR. JACOBY ON NEW PHYTOPHAGOUS COLEOPTERA. [Dec. 1, LICYLLUS, gen. nov. (HALTICIN^E). Body ovate; eyes entire; antennae filiform, the second joint short. Thorax transverse, narrow, the posterior angles tubercu-liform, oblique ; surface transversely depressed at the middle of the disk. Scutellum large, the apex rounded. Elytra with a deep depression below the base, irregularly punctured, their epipleurae disappearing below the shoulders. Posterior femora strongly incrassate, their tibiae simple and unarmed, the first joint of the posterior tarsi as long as the three following joints together. Claws appendiculate. Prosternum invisible between the coxae; meso-sternum narrowly transverse. Anterior coxal cavities open. The unarmed apices of all the tibiae, the transversely impressed thorax, and the absence of the elytral epipleurae below the middle, in connection with the deeply depressed space of the elytra below the base, form a number of characters which distinguish Licyllus from any other genus amongst the numerous family of Halticina3. A single species from Australia is known to me. LICYLLUS SPLENDIDUS, sp. nov. Piceous. Basal joints of the antennae, the thorax, anterior legs, and posterior tibiae testaceous ; elytra metallic green, two large spots at the base, and a semicircular mark below the middle of each elytron bright reddish cupreous. Length 2 lines. Head piceous, with a few fine punctures ; the frontal tubercles strongly raised, bounded behind by a rather deep groove ; the carina very indistinct; lower part of face testaceous. Antennae more than half the length of the body, obscure fuscous, the four or five lower joints testaceous, the third joint more than twTice as long as the second and longer than the fourth. Thorax three times as broad as long, the sides rounded at the middle, the angles, especially the posterior ones, produced in a tubercle, obliquely shaped behind the latter ; surface impunctate, with a rather deep transverse groove across the disk, not extending to the sides. Scutellum broad, black. Elytra widened below the middle, transversely depressed below the base, the latter raised; surface closely and finely punctured, the punctures more strongly impressed anteriorly than behind the middle, metallic green ; an elongate spot placed at the shoulders, which are prominent, a round spot near the scutellum, and a large semicircular ring, occupying nearly the entire latter half of each elytron, brilliant reddish cupreous; posterior femora piceous, the rest of the legs testaceous. Hab. Australia. (Two specimens are contained in my collection.) DlACANTHA OBERTHURI, Sp. 110V. Fulvous ; the sides of the breast black ; elytra distinctly punctured, their anterior half and a triangular spot near the apices black. Length 3 lines. Head impunctate, transversely grooved behind the frontal tubercles ; antennae rather short and stout, fulvous, the third joint slightly longer than the second ; sides of the thorax subangulate |
