with the distal portion broader and less attenuate than in the female. 

 Interspace between the mesosternal lobes slightly more longitudinal 

 than in the female; metasternal lobes subattingent. Caudal 

 femora slightly more robust than in the opposite sex. 

 Coloration similar to that of the female.

This specimen fullj^ agrees with a cotypic individual from Mendoza, 

 loaned by Prof. Bruner. Our specimen is grayer with the darker 

 maculations more decided, but these differences are purely individual. 



The species is only known from the Mendoza region.

We have before us several typical specimens of this species loaned 

 by Prof. Bruner and we are forced to the conclusion that he erred 

 in associating female specimens with converging lateral carinse 

 to the pronotum with males having those carinae non-converging. 

 The former are to our mind prasinus, which varies in the coloration 

 of the dorsum of the pronotum. Our two females agree with the 

 males in the character of the lateral carinse and the coloration. One 

 of the females is larger than the other, the measurements of the two 

 being as follows : 



23 Fig. 14 on page 41 of this paper is given as E. conspersus, but we are led to 

 believe from typical material of all of the species, kindly loaned by Prof. Bruner, 

 and our present series, that it represents prasinus.
