Oblong-ovate, robust, of a deep-blue colour, shining. Head very 

 short, transverse, when viewed laterally abruptly deflected; eyes 

 large, prominent, distant, reaching laterally as far as the hue of the 

 margin of the thorax ; between the eyes and immediately above the 

 insertion of the antennas (which are approximate) are two distinct 

 tubercles ; the surface of the head is smooth, impunctate and fulvo- 

 fermgineous, with four distinct but obscure linear thread-like mark- 

 ings, extending each from the middle of the base, the two outer ones 

 to the margin of the eyes, the two inner ones to the two tubercles 

 between the eyes. Thorax transverse, rectangular; the sides are 

 parallel and very slightly marginate : at the base is a broad transverse 

 depression (with a slight depression also at the anterior angles), which 

 gives an appearance of prominence to the anterior disc ; these de- 

 pressions are finely clothed with pubescence : the surface of the 

 thorax is smooth (under a high power very finely punctate) and 

 fulvo-ferrugineous. Scutellum triangular, flavous, distinct. Elytra 

 robust, subcylindrical, with punctures arranged in the form of striae, 

 of a bright dark-blue colour ; the line of the suture, by reason of a fine 

 margin of pubescence, is pale flavous; the shoulders are slightly 

 prominent ; the whole surface is clothed with minute and sparingly 

 distributed pubescence. Antenna} more than twice the length of the 

 elytra, filiform ; the first joint dilated ; the second minute, short, and 

 ovate ; the four basal joints flavous, fifth to eighth fuscous, ninth to 

 eleventh testaceous. Leys flavous.
