ACM^ODERA. 23 



If I have correctly identified this species, it is extremely close to A. rubronotata, 

 L. & G., and agrees with it in every respect, except in having the head and thorax 

 black (with a faint tinge of steel-blue), the elytra dark steel-blue, with numerous small 

 yellow dots, but sometimes without spots, and in having the thorax a little broader and 

 more rounded at the sides.

I only know this species from the figure and description. It would appear to differ 

 from A. semivittata, LeC, only in the absence of the yellow line on the side of *the 

 thorax.

I am unable to identify this species with any known to me. 



13. Acmaeodera superba. (Tab. II. fig. 5.) 



Caeruleo-viridis, aureo-micans, nigro-pilosa, subtus brevissime griseo-pilosa ; thorace elytris vix latiorc, disco 

 impresso subtiliter punctato, lateribus rugoso-punctatis, supra perparum oblique impressis, leviter rotun- 

 datis, angiitis posticis obtusis ; elytris sat convexis, striato-punctatis, macula rotundata ad basin, altera 

 laterali ad medium, fasciaque postice sanguineis.

Hab. Mexico, Puebla (Salle). — Bkazil (Brit. Mus.). 



The example from Brazil has a red spot on the thorax close to the posterior angle, 

 and the spot at the middle of the elytra is more transverse. 



The coloration of this species is so unlike that of any of the other species of the 

 genus that it is difficult to locate it satisfactorily ; but, setting aside the coloration, it 

 seems best to place it near A. scalaris, Mann., with which it agrees in form and general 

 characters.

This species has two yellow stripes reaching to the middle of the elytra, as described 

 both by Mannerheim and LeConte. In the British Museum there is an example
