ters of the cerci and the coloration of the limbs, however, place it in 

 magna, the aljsence of the facial decoration in Burr's species possibly 

 being due to the fact that his specimens were from Mexico, and for that 

 reason representing another species. As far as can be made from 

 Giglio-Tos' diagnosis of the female this specimen is his species.

Chapada, Matto Grosso, Brazil. April. (H. H. Smith.) [U. S. 

 Nat. Mus.] One male, one female. 



The female specimen agrees very well with the original description, 

 except that the size is slightly less. The subgenital plate of the male 

 is more produced and acute than in tigris, while the fastigium is more 

 distinctly truncate, with a very slight median emargination which is 

 more apparent in the male than in the female. The orange maculation 

 on the dorsal surface involves two segments in the male instead of one 

 as in the female, and the lateral lobes of the pronotum are subequal in 

 depth, not produced ventrad as seen in M. tigris.

Corumba, Matto Grosso, Brazil. March (Highland). (H. H. 

 Smith.) [U. S. Nat. Mus.] Two males. 



Chapada, Matto Grosso, Brazil. October (Campo). (H. H. Smith.) 

 [U. S. Nat. Mus.] One male. 



The Chapada individual has the tegmina but half the length of those 

 organs in the Corumba specimens. This species is considerably larger 

 than borellii, but very closely related.
