and sinuate at the sides, the front angles deflexed and 

 rounded ; it is of a shining-reddish colour, has a dorsal 

 row of six coarse punctures on each side the middle, and 

 has also six or seven other coarse punctures on each side 

 near the fr-ont part. The scutellum is smoky, closely and 

 finely punctured. The elytra are scarcely so long as the 

 thorax, tawny at the base, the other part infuscate ; they 

 are coarsely and moderately closely punctured. The hind 

 body is rather slender ; segments 2—4 are tawny in colour, 

 5 and 6 black ; the hind margin of the 6th and the base 

 of the 7th yellow ; segments 2 — 4 are each at the base 

 sparingly and finely punctured, the 5th is more closely, 

 and the black part of the Gth still more closely punc- 

 tured ; the extremity of the 7th segment, as well as the 

 anal styles, is fuscous. The legs are yellow, long and 

 slender ; the intermediate coxre distant. 



Ega ; two specimens, (? , ? . 



Obs. — Besides these individuals, I have three other 

 specimens which I believe represent two distinct but very 

 closely allied species, but as they are all females I cannot 

 feel quite sure about it.

 ones; 3rd joint longer than 2nd, lOtli longer than broad. 

 Thorax red, elongate and narrow, on each side of the

 neighbouring one by a perfectly distinct interval ; and also 

 with about seven other coarse punctures on each side. 

 Elytra hardly so long as the thorax, red at the base, then 

 smoky, with the extreme margin again reddish ; the punc- 

 tuation at the base is dense and only moderately coarse, it
