MlMELA SIMPLEX. 



Ovata, omnino ceneo-olivaceo-viridis, nitidissima ; clypeo creber- 

 rime, vertice cum thorace minus dense, elytris sparsim punctu- 

 latis ; elytris interstitiis linearum punctorum Icevibus, p/ieis 

 nonnullis lateralibus ; thorace lateribus trifoveolatis. 

 Long. 9^ lin. 



An ovate species, broader than Mimela splendens. The entire 

 body and legs uniform olivaceous brassy green, brightly shining. 

 The whole surface is minutely punctured ; but the punctures are few 

 and scattered on the elytra, and the spaces between the pairs of lon- 

 gitudinal lines of points are quite smooth ; a few transverse wrinkles 

 exist near the sides. 



Mimela ignicauda. 



Breviter ovata, supra viridi-cenea nitens, elytrorum maryinibus 

 prcecipue apicalibus aureo-cupreis ; clypeo maris anyustissime, 

 faeminee late testaceo maryinato, minute punctulato ; Hhorace 

 lateribus irreyulariter late foveolatis, sulco utrinque basali pro- 

 funde impresso, maris unicolori, fcemince testaceo maryinato; 

 elytris yrosse, parum profunde et subsparsim punctatis, inter- 

 stitiis anyustioribus Icevibus, latioribus interdum transverse p/.i- 

 catis ; corpore subtus obscure ceneo-piceo ; pedibus maris ob- 

 scure ceneis, femoribus testaceis, fcetnince pedibus testaceis aneo 

 tinctis. 

 Long. 5-5g lin. 



A small species, broadly ovate in the male, more elongate in the 

 female, with the elytra, in both, dilated near the apex. The colour is 

 dark brassy green, passing gradually into coppery on the sides of the 

 elytra, and of a brilliant golden copper below the apical callus. The 

 thorax is very minutely punctured ; but the sides are occupied with 

 a number of shallow irregular depressions, and there is a deep sulcus 

 running obliquely near the hind margin on each side. The male has 

 scarcely any trace of pale-testaceous margins; and, beneath, the femora 

 are only sometimes of this colour ; the female, however, has broadish 

 pale margins to the clypeus and sides of thorax, and the under sur- 

 face and legs are in large part of the same hue. The pygidium is 

 brassy green and sparsely punctured. 



Mimela chryseis. 



M. splendenti colore similis, sed in utroque sexu oblonyior, yros- 

 sius punctata, oblonya, testacea ; capite thoraceque viridi vel 

 aureo-viridi micantibus, nitidissimis ; elytris auratis ; clypeo 

 densissime ruyoso-punctato ; thorace yrosse subsparsim punc- 

 tato ; elytris yrossius punctatis, sinyulis sutura et costis (tion- 

 dum elevatis) quatuor Icevibus lineis punctorum maryinatis ; 

 pyyidio ylabro, splendente, convexo, yrosse distincte punctato, 

 punctis rotundis ; corpore subtus et pedibus testaceis, viridi- 

 aureo micantibus, pectore lateribus coxisque posticis dense ru- 

 yoso-punctatis, abdomine interdum cupreo. 



Long. 7—9 lin.
