 of the front, but with two punctures on each side Let ween 

 the eyes, and a i"e\v other coarse punctures towards tlic

 lowish, with a slight brassy reflection ; it is a good deal 

 narrower than the elytra, and distinctly narrowed behind; 

 on each side the middle it has a series of five extremely 

 coarse punctures, and outside these about six other very 

 coarse punctures on each side. Elytra yellow, about as 

 long as the thorax, coarsely and rather closely punctured. 

 Hind body yellow ; the basal segments sparingly punc- 

 tured; the otli and 6th segments blackish, except the hind 

 margin of the latter ; the 7th yellow, anal styles nearly 

 black. Legs yellow. 



The male has the hind margin of the ventral plate of 

 the 7th segment of the hind body very slightly emar- 

 ginate.

Antennas about as long as head and thorax, slender, 

 yellowish; 3rd joint longer than 2nd, 4 — 10 each is a little 

 shorter but scarcely stouter than its predecessor, the 4tli 

 quite twice as long as broad, and even the 10th longer 

 than broad. The mandibles and palpi arc yellowish. The 

 head is slightly broader than the thorax ; the front dis- 

 tinctly produced between the antenna?, with a deep, longi- 

 tudinal impression along the front, with two punctures on 

 each side in a line near the inner margin of the eyes, and 

 with numerous other coarse punctures on each side at the 

 back ; it is of a shining-brassy colour. Thorax much nar- 

 rower than the elyti-a, its length considerably (one and 

 a-half times) greater than its width ; it is narrowed behind
