Mr. C. O. Waterhouse on Madagascar Cetoniidge. 77 



the second and fourth interstices raised, this latter abbreviated ; 

 the first and third interstices with some strong punctures ; the 

 subapical callosity obtuse, the apex smooth. The pygidium 

 with a few punctures. Tarsi black. 



The male has the anterior tibiae with three acute small teeth, 

 the anterior tarsi short and extremely thick ; the posterior 

 tarsi as long as the tibia, moderately stout. 



The female has the three teeth of the anterior tibiae close 

 together. The anterior tarsi are short and more slender, the 

 posterior tarsi are much shorter than the tibia, less stout than 

 in the male. 



This species is very peculiar, and recedes somewhat from 

 Euchilia, but agrees better with that genus than with Cop- 

 tomia. 



Pygora hetta, 



Viridi-prasina, subtus plus minusve cyaneo micans, nitidissima ; 

 clypeo piceo ; thorace olivaceo, linea mediana tenui lateribusque 

 viridibus, his cupreo tinctis ; elytris octostriatis, olivaceis vel 

 cyaneis, marginibus viridibus et cupreo-aureo tinctis ; pygidio 

 leviter convexo, cyaneo, parce punctate- ; pedibus pallide piceis. 



Long. 6 lin. 



Head and clypeus very thickly and rather strongly punc- 

 tured, the latter very slightly emarginate. Thorax moderately 

 thickly and distinctly punctured, nearly parallel at the sides 

 to a little in front of the middle, then obliquely narrowed 

 anteriorly, olive-green (or dark cyaneous), with a fine mesial 

 line and the sides pale green. Scutellum smooth, pale green. 

 Elytra each with four strong striae; the third interstice nearly 

 flat, the others convex ; the shoulders pitchy. 



The male has two acute teeth to the anterior tibiae, with an 

 indication of a third ; and the first abdominal segment has a 

 white spot on each side. 



The female has three acute teeth to the anterior tibiae ; and 

 the abdomen has no spots. 



In the same collection with the above were two examples 

 of rather larger size (7 lines), which have the sides of the 

 thorax, the scutellum, and the sides of the elytra bright golden 

 coppery ; the colour of the thorax and elytra is less dark. I 

 believe them to belong to the same species. 



Pygora imncticollis. 



Depressa, latior ; capite crebre punctato, vertice viridi, clypeo piceo ; 

 thorace ante medium oblique angustato, postice subparallelo, 

 nigro-cyaneo, crebre fortiter punctato, lineis tribus longitudina- 

 libus viridibus, cupreo micantibus, scutello viridi laevi ; elytris 

 piceis, fortiter octostriatis, interstitiis convexis, sat crebre punc-
