258 The late Mr. F. Bates's Revision 



k.k. (S 9) Pygidium without short 

 decumbent hairs, frequently tu- 

 mid, setose at sides and apex ; 

 usually smoother and more or 

 less punctate at the apex in (^ . 

 I- (6) Pygidium bicolorous, the 

 sides dark (usually green), the 

 middle (rarely the apex only) 

 pale, tarsi pale. 



7H. {^) Front of clypeus entire, 

 narrowly rounded, or 

 pointed, and more or less 

 reflexed, or recurved ; the 

 side margins distinctly 



sinuate f paragnayensis, i\.sy). — 



GhampionijTi.sTp. — fuha, Blanch. — ancilla,i\. sp. 

 — jKillidipeimis, n. sp. 

 m.m. i^) Front of clypeus 

 either sinuate or dis- 

 tinctly emarginate, the 

 side margins scarcely 



sinuate | Hsevissima, Burm. — 



fracida, n. sp. — cayennensis, n. sp. 

 To this division belong probably all those bewildering forms, 

 prasina, Burm. ; seriiginosa, L. ; glanca, Oliv. ; alliacea, Germ. ; 

 herbacea, Bl. ; luridipes, Bl. ; chlorana, Er. It is impossible at 

 the present time to distinguish these by the quite inadequate 

 descriptions. 



II. ( (^ ) Pygidium unicolorous : tarsi 

 black or dark metallic. 

 a. Thorax of normal form, with- 

 out median groove. 



j3. Testaceous . chakothorax, Perty. — sordida, Germ. 

 /3./3. Metallic green .... cyanipes, Kirby. 



■f In the (^ the last abdominal segment is polished and nearly 

 glabrous, with the sides — and often the hind margin — testaceous ; in 

 the $ it is duller, paler, roughly, and entirely, sculptured, con- 

 colorous with the pygidium ; altogether in strong contrast to the 

 other — smoother and much darkei' — segments. 



X In some cases the front of the clypeus of the (J is so feebly 

 sinuate as to be almost entire, but it is generally broader and less 

 rellexed. The last abdominal segment is usually testaceous at the 

 sides in the ^ ; in the $ it is very rarely paler than the other 

 segments, but is much more strongly and closely sculptured.
