300 Mr. F. Bates's descriptions of 



The $ lias the form more oblong, the antennae longer, 

 the mtervals on the elytra rougher, and the femora are all 

 pilose beneath on their basal half. 



Long. 10 lin. 



Antananarivo. 



Nesogena rutilia (Fairm. i. 1.), n. sp. 



Also near Batesii, but the form is much more oblong 

 and parallel ; the prothorax metallic copperj-feneons, 

 more or less tinged with pnrple, especially at the sides ; 

 sides more obliquely narrowed anteriorly ; the elytra nar- 

 rower, more parallel, of a bluish-violet colour, or bluish- 

 green, passing into palish-purple at the base, sides and 

 suture ; the reflexed margins golden with purplish re- 

 flections, narrower, not sinuous nor distinctly expanded at 

 the middle. 



The $ has the intermedia,te femora only pilose beneath. 



Long. 10^ lin. Width of elytra across the middle 

 4 3 lin. ; in Batesii they are SJ^- lin. across. 



Nesogena lucida, n. sp. 



Near speciosa, but smaller, more elliptic, much less 

 convex, still more (especially the ])rothorax) brilliant, the 

 basal angles of the prothorax produced, acute and out- 

 wardly directed. 



Head brilliant emerald-green, finely and not closely 

 punctured ; epistomal suture and the furrow at each side 

 the front strongly marked, these latter not distinctly con- 

 nected behind ; prothorax golden -brassy, of the most 

 intense brilliancy, entirely (and broadly at the sides) 

 bordered with emerald-green, which border is inwardly 

 finely edged with blue and purple ; minutely and remotely 

 punctured, transversely wrinkled at the sides, close to the 

 margin ; the usual furrow along the middle of the base ; 

 hind angles produced, acute, outwardly directed; scu- 

 tellum bluish-green, irregularly punctured ; elytra very 

 feebly convex, golden-coppery on the back, passing into a 

 beautiful palish-purple witli violet reflections on the sides 

 and apex, the outer interval and the lateral margins of a 

 brilliant emerald-green ; sides sinuate, broadly margined, 

 expanded at the middle ; punctate-striate, most stroiigly 

 so at the sides and apex, where also the intervals are 

 narrower and somewhat convex ; intervals minutely punc- 

 tulate and indistinctly alutaceous ; underside brilliant
