264 Mr. C. O. Waterhouse on Coleoptera 



Acmceodera tricolor, sp. n. 



Briglit green, the disk of the thorax and the suture of the 

 elytra violet, the margins of the elytra tinted with golden. ? . 



Long. 12 mm. 



Hah. Daraava [Heyne, ex coll. Kerremans). 



Somewhat intermediate in form between A. viridianea and 

 A. grandis. Thorax scarcely hroader than the elytra at the 

 base, not much rounded at the sides. Median channel 

 elongate elliptical, the punctures moderately large and 

 moderately close together. The disk tinted with violet, the 

 punctures fine but distinct near the base, strong and mode- 

 rately close together in front, the punctures becoming 

 crowded together at the sides. Elytra with the suture violet, 

 with a single line of punctures behind the middle. First 

 iTiterstice smooth, with an irregular line of punctures from 

 about the middle ; second interstice smooth, gently convex, 

 with a few punctures at its sides near the apex ; the re- 

 maining interstices in the discal area much interrupted by 

 punctures and zigzag rugie, but flat and with a single line of 

 rather strong and somewhat closely placed punctures towards 

 the apex. Body black beneath. 



Acmceodera Brooksi, sp. n. 



Bluish green, the disk of the thorax and suture of the 

 elytra violtt-blue ; apex of the elytra carinate. ? . 



Long. 12 mm. 



Hah. Buluwayo, Matabele Land {F. Brooks). 



Size, form, and appearance of A. viridianea, but rather 

 more blue-green than that species usually is, and with the 

 entire suture and apex of the elytra violet-blue. It is at 

 once distinguished by the cariuse at the apex of the elytra. 

 Thorax with the median channel elongate-elliptical, closely 

 pvmctured; the punctures on the disk on each side of the 

 channel are rather fine and slightly separated, but they 

 become gradually less fine and closer towards the sides. 

 The sides closely punctvircd, the punctures much smaller 

 than in viridicenea and closer together, but not confused as 

 they are in many species, and there is a small smooth spot 

 towards the anterior angles. Elytra with the suture and 

 the first and second interstices smooth for two thirds their 

 length, then with a line of punctures that become more 

 impressed towards the apex, and the interstices have their 

 margins raised and slightly cariniform. The third and fourth 

 interstices have a line of punctures for their entire length.
