Brief SummaryRead full entry
DescriptionTestaceous yellow, with the head, pronotum (except a narrow pale margin at the sides and base), the median part of the metasternum, the front tibiae, the greater part of the middle and hind tibiae, and a large oval spot upon the lower surface of the four posterior femora, greenish- or coppery-black. The extreme edges of the prothorax, elytra, and all the segments of the body and legs are also dark.
Broadly oval and convex, smooth and moderately shining, with a thin clothing of yellow setae upon the legs and lower surface.
The head is semicircular, with the front margin strongly reflexed and very feebly sinuate in the middle. The forehead is finely and closely punctured, and divided from the clypeus by a strong, feebly curved carina.
The pronotum bears rather sparse granules in its median part, replaced behind by fine scattered punctures, and is smooth and unpunctured round the circumference. There is an entire raised margin, the sides are nearly straight in front, feebly sinuate behind, the front angles sharply produced, the hind angles obsolete, and the base feebly angulate in the middle. The elytra are finely striate, with the intervals flat and unpunctured. The pygidium bears an angulate basal carina and a few scattered punctures. The metasternum bears only a few setigerous punctures.
In male, the clypeus is rather feebly rugulose and shining. The vertex bears a pair of slender horns, curving outward and inclined a little backward, a little flattened at the base and not united. The front of the pronotum is very smooth and shining and almost vertical in the middle, the declivity surmounted by two minute prominences separated by a slight groove. The front tibia is elongate, slender and curved, its inner extremity produced into a long spur and its external teeth rather widely separated.
In female, the clypeus is rather closely rugulose and opaque, and the vertex bears a strongly elevated straight carina. The front of the pronotum is vertical in the middle and produced on each side, forming a pair of strong, slightly divergent, blunt processes.
