transversus, lateribus antemediis subrotundatis, in medio trans- 

 verse valde depressus, impunctatus, flavus {scutellum impunctatum, 

 rufo-fuscum ; elytra parallela, impubescentia, punctata, nigro-

 corpus subtus nigrum, abdomine rufo. 

 Long. Corp. lin. 7; lat. lin. 3. 



Nearly allied to C. parallela of this paper, but separable from 

 it by the blue (not fuscous-black) colour of the elytra, which are 

 iin pubescent, nearly glabrous, and distinctly punctate, not 

 rugose.

15. C. tenuicornis. 

 C. elongata, subparallela, subpubescens, nigra, femoribus et thorace 

 rufis ; caput longitudinaliter ad medium et transverse inter 

 oculos foveolatum, punctatum, nigrum ; thorax penitus planus, 

 vix ut in C. parallela fortiter transverse depressus, rufus ; scu- 

 tellum leviter punctatum, nigrum ; elytra subparallela, elongata, 

 rugosa, nigra ; antenna subgraciles, nigrse ; pedes nigri, femoribus 

 rufo-fuscis ; corpus subtus nigrum.

Very nearly allied to C. parallela, but differing from it in its 

 less parallel form, the transverse fovea on the head, the less 

 marked transverse depression of the thorax, and the colour of 

 the underside ; the antennse, also, are evidently somewhat more 

 attenuate.

16. C. binotata, Dej. 

 C. parallela, subrugosa, rufo-flava, elytris et maculis duabus tho- 

 racis nigro-cyaneis ; caput leviter punctatum, foveolatum, nigrum; 

 thorax sparsim punctatus, flavo-rufus, macula utrinque circulari 

 submedia nigra ; scutellum impunctatum, flavum ; elytra leviter 

 rugosa, subpubescentia, nigro-cyanea ; antenncB nigrse ; corpus 

 subtus rufo-fuscum ; pedes nigro-fusci, femoribus rufo-flavescen- 

 tibus. 

 Long. corp. lin. 6 ; lat. lin. 3. 



To be distinguished from all its congeners by the two con- 

 stant black maculations on the thorax ; in size not unlike M. 

 Brasiliensis, but differing in coloration, a trifle more parallel 

 and narrower, and with the thorax not quite so obviously de- 

 pressed. 



Brazil. 



Genus XIII. Corata. 



Satis elongata, parallela et robusta. Caput verticale. Palpi maxil- 

 lares elongati. Thorax subquadratus, penitus transversus, margine 

 anteriore recto, angulis anticis distinctis (incurvatis, corpus arete 

 amplectentibus), lateribus atque etiam angulis posticis subrotundatis;
