Black, rather shining; thorax in front narrowly, behind much 

 more broadly, red; abdomen red, the fourth (visible) and greater 

 part of the fifth segments pitchy-black; antennae, palpi and legs 

 testaceous, the 2nd, 3rd and 4th joints of the former, infuscate.

From the description this species would appear to be allied to 

 ('. aspericolle, Fauv. Head narrower than in G. indicum, Kr., 

 with the temples straighter and convergent, and the occipital fossa 

 rhomboidal; the front and the triangular smooth space between 

 the antennal tuberosities shining, reddish-testaceous, without visible 

 sculpture ; the rest of the surface (except in the immediate vicinity 

 of the longitudinal sulcus, occipital fossa, and the temporal regions) 

 coriaceous, with obsolete setiferous puncturation, more distinct on 

 the temples. Antennae long, the 1st joint as long as the five follow- 

 ing joints together, the 2nd a little shorter than the 3rd, the 2nd 

 to the 9th all distinctly longer than broad, gradually decreasing in 

 length, the 10th scarcely longer than broad, 11th short, ovoid. 

 Thorax distinctly longer than broad, obtusely angulate before the 

 middle, narrowed from thence anteriorly in a nearly straight line, 

 and posteriorly in a straight line; disc in the posterior third with a 

 broad, deeply grooved keel, anteriorly with a digital impression; 

 the raised lateral lines distinct throughout, turned inwards and 

 confluent with (he central carina posteriorly, and with the margins 

 of t lie digital impression anteriorly; the sides with rather obsolete 

 impression behind the anterior angles; puncturation coarse, rugose 

 and confluent, wanting on the anterior border, the digital impression 

 and the spaces between the central keel and the lateral lines, all 

 of which arc completely smooth and shining; the surface red, 

 with a narrow black fascia nearer the anterior than the posterior 

 horder. Scutellum red, shining, impunetate. Elytra black, rather
