 presso, cum thorace lajvibus ; hoc marginibus anguste

var. A, capite thoraceque supra infraque nigris =r«yi- 

 pennis, Chevr. 



var. B, capite thoraceque rufo, hoc tertia discoidali 

 nigra, prosterno nigro, epipleuris rw^s>^=cardinalis, Chevr. 



var. C, capite thoraceque rufo, prosterno et epipleuris 

 rufis = mcridioncdis, Crotch. 



I consider these three forms referable to one species, 

 though the variation in outline is considerable. 



The intermediate coxal line is well marked. 



The Chontales specimens all pertain to var, C (Acg. me- 

 ridionalis, Crotch).
