PROSCOPIXAE 

 Tetanorhynchus sublaevis Brunner 

 1S9(J. Ttlaui/rhynchas sublaevis Brunner, Verhandl. k.-k. zool.-botan. Gesell. 



Wien, xl, p. 105, pi. iv, figs. 5a to 5c. [Theresopolis, State of Santa Catha- 



rina, Brazil.] 



Piquete, State of Sao Paulo. One male. 



This specimen has the postocular section of the head sUghtly 

 longer in proportion than in the male figured by Brunner, but as 

 there is some variation in this respect in allied species we prefer 

 to consider it an individual feature.

Porto Alegre, State of Rio Grande do Sul. 1912. fP. P. 

 Buck.) Three males, one female. 



Sao Paulo, State of Sao Paulo. February 8, 1906: garden 

 field; open woods. One male, one female. 



Ypiranga, State of Sao Paulo. February, 1913. (H. Llider- 

 waldt.) One female. 



These specimens all have the rostrum longer than material of 

 both sexes from Cordoba and Carcarana, Argentina, and males 

 from Sapucay, Paraguay and Misiones, Argentina; females from 

 the latter localities, however, agree with the Brazilian material 

 in the relative length of this portion. Owing to the uncertain 

 definition of a number of supposedly distinct species, i. e. costulata, 

 calamus, multispiyiosa and burmeisteri, we prefer, for the present at 

 least, to call the specimens recorded above, costulata. The dif- 

 ferences given for these species may be racial, environmental or 

 genetic, but we have not sufficient material or information to 

 hazard an explanation along any one of these lines. We have 

 already called attention to the variation found in the number of 

 caudal tibial spines in this species.^
