Mr. C. O. Waterhouse on new Cohoptera. 447 



The female is much flatter than that of 0. gazella, the 

 thorax parallel at the middle of the sides, the lateral angle 

 projecting only slightly. The black triangular patch, com- 

 mon to both elytra, extends a little over the humeral angles, 

 narrowing rapidly posteriorly to a point at the apex. In the 

 colour of the elytra it is more like 0. cuvera, but the black 

 is broader at the base and narrower at the apex. 



This species should be placed next to 0. gazella.

Amyia punctipenniSj n. sp. 



Obscure C3\anesccns, uitida ; elytris creborrime sat fortiter punc-

 Long. 9 millim. 



Much narrower than A. cliryselytra^ and somewhat resem- 

 bling EumerophUus in general form. Head rather strongly 

 punctured, longitudinally impressed in front ; with a slight 

 swelling on each side of the upper part of the forehead, and 

 two very slight obtuse tubercles on the lower part of the 

 face. Thorax a little broader than long ; very gently arcuate 

 at the sides ; the punctuation sparse and obscure. The 

 disk is slightly transversely impressed in front (leaving the 

 anterior margin somewhat raised) ; longitudinally rather 

 deeply impressed behind. Scutellum seneous. Elytra sub- 

 parallel for two thirds their length and then narrowed to the 

 apex, declivous at the apex ; with a large shallow impression 

 at the base between the shoulder and the scutellum ; closely 

 and rather strongly punctured, the punctures generally elon- 

 gate and having an asperate appearance. Prosternum densely 

 punctured. Abdomen very delicately and moderately closely 

 punctured'; with a slight fovea on each side, indicating the 

 division between the first and second segments.
