 punctured than in the male. 



Ega ; eleven intlividuals.

 7th segment shows no variation in a series of six $ indi- 

 viduals.

 nigro, ano testaceo ; prothorace omnium fortissime punc- 

 tato. Long. corp. 4i lin. 



Mas: abdomine segmento sexto ventrali apice medio 

 obsolete emarginato, segmento 7° subtriangulariter inciso. 



Antennre yelloA^-ish, rather short and stout, much 

 thickened towards the extremity; joints 2 and 3 about 

 ecpuil, 4th longer than the 5th and 6th, these two short ; 

 the Gth transverse, 7 — 10 strongly transverse ; 11th long, 

 stout and pointed. Head taAvny, coarsely and densely 

 punctured, the punctuation more sparhig on the vertex. 

 Thorax not quite so long as broad, distinctly broader in 

 front, and with the sides a little sinuate, its upper surface 

 extremely closely and deejjly punctiu-ed; the punctures 

 are numerous and close, and leave a very narrow line at 

 the base, a central line, and a spot near the front angles, 

 smooth. Elytra considerably longer than the thorax, of 

 a similar colour to it, and the head coarsely and rather 

 closely punctured, with their pubescence rather coarse and 

 distinct. Hind body narrowed towards the apex, black, 

 Avith the extremity of the 6tli segment, and the Avhole of 

 the 7th, yellow; the 2nd segment is imjmnctate, segments 

 3 — 6 closely and finely punctured and densely pubescent ; 

 the pubescence on segments 3 — 5 yellow, 7th segment 

 nearly impunctate ; 8th segment with its lateral lobes pale 

 at the base, tawny brown at the extremity. Legs yellow. 



In the male the hind margin of the Gth segment of the 

 hind body is slightly emarginate, and the 7th has a rather 

 narrow and moderately deep notch in the middle of the 

 hind margin ; in the female the hind margins of the Gth 

 and 7th segments are simple, that of the 7th being gently 

 rounded ; the last joint of the antennas seems to be shorter 

 in this sex than in the male.
