This species is very closely allied to M. fulgidipennis, Westw., from the Amazons, but 

 is rather different in colour. It has not a brown stigma on the elytra, and the tarsi 

 are not annulated with black. 



CHCEKADODIS, Serv.

The American species of this genus differ from the Asiatic in having the anterior 

 femora more slender, with the superior margin straight or subsinuated, and with the 

 black macula of the inner side placed against the inferior margin; their anterior 

 coxse also in rest do not reach so far back as the prothorax. In the Asiatic forms 

 the anterior femora are wider, with their superior margin arcuated, and with the 

 black macula placed against the superior margin, the anterior coxse reaching back- 

 wards beyond the prothorax. 



The American species may be separated as follows : — 



Inner face of the anterior femora : 



a. without black spot. — [strumaria, L.] 

 aa. with a black spot.— [cancellata, Serv.], [laticollis, Serv.], [rhomboidea, Stoll], rhombicollis,
