individuals all have the caudal tibiae more or less extensivelj^ pinkish 

 purple distad, in the female this color covering almost the whole of 

 the tibiae, while the dorsum of the tarsi are suffused with the same 

 color in all. The pale head and pronotal lines vary from dull straw 

 yellow to clay color, the pale areas of the caudal femora closely 

 agreeing with this color, while the darker pronotal bars vary from 

 dark oil green to purplish brown; the dark areas of the pleura and 

 caudal femora agree in color with the dark pronotal bars. 



The previous records of this species are from Montevideo (Ser- 

 ville) and Patagonia (Pictet and Saussure). 



*Diponthus festivus Gerstaecker.

 193. [Porto Allegre, Rio Grande do Sul, BrazU.] 



Misiones. November 26, 1909; December 1 and 18, 1909-1910. 

 Three females. 



This striking species has only been recorded from the type locality 

 and by Pictet and Saussure without exact locality from the same 

 state (Rio Grande do Sul). 



* Diponthus crassus Bruner. 



1910. Diponthus crassus Bruner, Entom. News, XXI, p. 303. [Puerta 

 Bertoni, Paraguay.] 



Misiones. October 27, 1909; November 9 and 12, 1907 and 1909; 

 December 12, 1909. Four males, five females. 



These specimens are perfectly typical of this very distinct recently 

 described species. As the male was previously unknown, the 

 measurements of an average individual of that sex may be of interest r 

 length of body, 24 mm.; length of pronotum, 5.2; length of tegmen,. 

 16.3; length of caudal femur, 14. Of the above series three pairs, 

 taken in November and December, were captured in coitu. 



The type locality and the Misiones are the only localities from which 

 the species is known.

Misiones. May 5, 1910; November 12, 1909; December 12, 1910. 

 (Nos. 3 and 6.) Three males, six females. 



The variation in color tone previously noted by us in this species^^ 

 is evident in the present series. Information with the species is to 

 the effect that it is very common.
