Show 790 MR. M. J A C O B Y O N N E W LL»ec. 10, nearly equal length, black, the seventh and eighth joints light flavous. Thorax transverse, sinuate behind the middle, anterior angles slightly prominent; surface impunctate, flavous, with a large black spot at either side. Scutellum black. Elytra dilated posteriorly, broadly margined at the middle; surface strongly and closely punctured, metallic green, the margins and suture narrowly, the apex broadly flavous. 33. DIABROTICA FOVEIPENNIS, sp. nov. Oblong. Flavous ; thorax bifoveolate, minutely punctate ; elytra finely but distinctly punctured, flavous, the suture (narrowly) and four very obsolete spots on the disk ferruginous, lateral margins interrupted in the middle by a deep fovea. Length 3| lines. Hab. Dueiias, Guatemala. Head very finely punctured, as long as broad; front with a small fovea; encarpse and carina distinct; antennae filiform, longer than half the body, second joint short, third of double the length, entirely flavous. Thorax transverse, subquadrate, sides finely margined, strongly contracted behind the middle, anterior angles not pointed, posterior ones slightly thickened, surface minutely punctured, bifoveolate on the' disk, the foveae closely approached. Scutellum smooth. Elytra slightly widened at the middle, closely and more deeply punctured than the thorax, each elytron with a deep fovea, situated immediately before the middle of the lateral margin, the latter itself being produced at that place into a triangular tooth, while the interior of the fovea contains another still more pointed triangular elevation ; two indistinct spots, one before the other behind tbe middle, on tbe disk of each elytron, as well as the suture narrowly, ferruginous. Underside and legs entirely flavous. Claws appendiculate. Collected by Mr. Champion. This and the following species I rather reluctantly describe under the generic name of Diabrotica, on account of their appendi-culated claws and the curious elytral foveae. The latter character, I think, is peculiar to the male insect; but as in all other particulars the species agree with Diabrotica, I have placed them there for the present. 34. DIABROTICA TRIPUNCTATA, sp. nov. Elongate. Obscure fulvous, base of femora and the antennae black; vertex ferruginous; above yellowish or light testaceous, opaque. Scutellum, three triangularly placed spots ou each elytron, and the suture black. eS (?). Elytra with a deep fovea near the lateral margin, before the middle. Length 4 lines. Hab. Capetillo, Duenas (Guatemala). Head not longer than broad, longitudinally and transversely grooved between the eyes; vertex ferruginous, lower part of face light testaceous; antennse of the same shape and length as the pre- |
