AbstractLength from the front margin of the inter-antennary ridge to the apex of the elytra 56 mm.; greatest breadth of the prothorax 12 mm.; breadth at the shoulders 16 mm. — Pale fulvous, with the head (except the middle of the throat), the seven basal joints of the antennae 1), the pronotum, the scutellum, two spots on each elytron, the front margin of the prosternum, the sides of the mesoaud metasternum, a narrow border around the abdomen, the pygidium and the legs (the three basal joints of the tarsi excepted) black, green or blue. The two dark green spots on the elytra are as follows: the anterior one, situated at one third of the length of the elytra, is transverse and originates from the lateral margin but does not reach the suture; the posterior one is apical, longitudinal, and slightly oblique; it occupies the inner half of the apical fourth of the elytra and is connected with the suture for about two thirds of its length, reckoned from the sutural angle. The fulvous coloured portion of the elytra is covered with a dense orange pubescence, on the green spots the pubescence is black. The pubescence on the black joints of the antennae is black, that on the under surface of the body fulvous. The inner margin of the anterior tibiae is covered with a dense fulvous pubescence.
The head is shining black and sparsely punctate, except on the inter-antennary ridge where the punctures are more numerous; the mandibles are rather densely covered towards the base with elongate punctures; the inter-antennary ridge is slightly concave and, in the middle, divided by an impressed line which ends anteriorly in a smooth transverse impression; the outer angles of the ridge are bluntly pointed; the under surface of the head is transversely wrinkled. — The antennae are relatively short, the top reaching to the hind margin of the first abdominal segment; the scape is broad and short, measuring half the length of the third joint, widened at the top on the outside and densely covered with minute punctures intermixed with some larger ones; the third joint is rather strongly curved, it becomes gradually thicker towards the end and has not quite double the length of the fourth; the fourth joint is equal in length to the fifth, the succeeding joints gradually decrease in length except the eleventh which is somewhat longer than the tenth; joints eight to ten are subdentate at the apex in front.
