U. sordideflava, depressa ; antennis nigris, apice ferrugineo, thorace lineis tribus nigrescentibus; eli/tris marginibus, strigis duabus obliquis fasciaque apicali a?neis, humeris triangular iter expla-natis, apice truncato denticulato, dente externo acuto aneo. Long. 3| lin. Antennae short, longitudinally carinate, the seventh joint with difficulty separable from the eighth. Thorax narrowed in front, very strongly and rather closely punctured ; a median line and one on each side nearly black. Scutellum pitchy. Elytra with the shoulders triangularly expanded and raised ; the apex denticulate, the outer angle produced into a strong tooth. Each elytron has two very strong shining costae, besides a less marked sublateral one commencing under the shoulder and continued to and along the apical spine. The double rows of punctures in the interstices are very strong and close. There are the following dark bluish aeneous markings-a line over the humeral angle, an interrupted oblique dorsal line before the middle, a similar one behind the middle, the lateral margin (except at the extreme base and apex), and the apical spine; there is a brown (aeneous-tinted) line extending from one apical angle to the other, and a short line near the apex between the second and third costae. The metasternum has a black line along its lateral margin. This species is allied to U. angulata, 01. 29. UROPLATA DEPLANATA, n. sp. (Plate XXX. fig. 16.) U.ferrugineo-flava ; capite antennisque nigris; thorace linea laterali nigro-a?neo tincta; elytris cyaneo-nigris, vitta lata communi haud ad apicem attingente ferrugineo-flava, ante medium et post medium dilatata, ad apicem truncatis, denticulatis, angulo externo obtuse producto. Long. 3-2- lin. The antennae have the basal joints shining and sparingly punctured. The thorax is flattened, closely and strongly punctured, with a well-marked transverse impression on the disk behind the middle, and with a second smooth impression across the basal lobe. Each elytron has three shining costae, the lateral one finer and less strong than the others; the double rows of punctures in the interstices are verv strong and close; there is a little blue-black, this colour extending a little over the shoulder and about the midde; the sides are finely and acutely crenulate; the apex is broadly truncate, the external angle flattened and obtusely produced. The two apical segments of the abdomen are pitchy in the middle. 30. UROPLATA BISPINOSA, n. sp. (Plate XXX. fig. 17.) U. nigra ; thorace lateribus ferrugineo-flavis; elytris ferrugineo-flavis, macula scutcllari, linea brevi sub humero, apiceque nigris, hoc truncato, angulo externo in spinam acutam producto. Long. 3\ lin. Thorax very convex, constricted before the anterior angles, which 18* |
