Abdomen (beneath) seldom, and legs never, fiery, rather green or blue ; pu- 

 bescence thinner ; puncturation very variable, but probably always coarser 

 than in Ruddii (often vei'y much so), and becoming remote towards the 

 apex of segment 2 (which is usually vei'y brilliant), always closer again on 

 segment 3 ; metathoracic spines more stout and triangular ignita. 



I ought not to leave the subject without expressing my hearty- 

 thanks to the collectors, especially Dr. Mason, who have so kindly 

 trusted me with their valuable specimens, and to M. du Buysson and 

 Mr. "Waterhouse for giving me the inestimable advantage of their skill 

 and knowledge in clearing up difficulties of identification.

 * Antenna 16-jointed in the ? only ; in the J 15-jointed, and provided with a 

 looped appendage to the 3rd joint. Cubitus destitute of brictling hairs. 

 A. Bristling hair in parts of the wing extended beyond the shortest Hne 

 from the end of the subcosta to the end of the anal nervure. 

 Eirst joint in the <J antenna? longer than the next two joints 

 combined ; 2nd joint stout, ovoid or subglobular ; 3rd joint less 

 stout, oval, stouter and longer than the 4th joint (the above- 

 mentioned appendage of agglutinated hairs is peculiar to this 

 sex) ; the articular appendages of the flagellum short, curved at

 Wing pointed at, or in close proximity to, the end of the cubitus ; 

 bristling hair extended farthest upon the posterior radius.
