Misiones. December 14, 1910. (No. 29.) Two males, one 

 female. 



These specimens are smaller than topotypes, which are also before 

 us, although otherwise they are inseparable. A pair of the Misiones 

 individuals measure as follows: 



Male. Female. 



Length of body 16.5 mm. 20.2 mm. 



Length of pronotum 3.5 " 4.5 '* 



Length of tegmen 13.5 " 16.2 " 



Length of caudal femur 9.2 " 11.3 " 



Information with the specimens is to the effect that the species is 

 common. It has only been recorded from Sapucay, Paraguay, 

 Chapada, Matto Grosso, Brazil, and the Misiones, Argentina. 

 Leiotettix politus n. sp. 



Type: cf ; Misiones, Argentina. December 12, 1910. (P. Jor- 

 gensen. No. 6. [Acad. Nat. Sci. Phila., type No. 5,219.] 



Allied to L. sanguineus Bruner, but differing in the narrower 

 interspace between the eyes, less protuberant and more 

 ovoid eyes, less regularly rugulose dorsum of the 

 pronotum, the more decided median carina of the same, 

 the decidedly blunt instead of strongly acute prosternal 

 spine, the slenderer distal portion of the cerci, the more 

 brownish coloration and pale reddish caudal tibiae. 

 There is no close relationship to either L. flavipes Bruner 

 or hastatus Rehn. 



Size small; form moderately compressed. Head 

 with the interspace between the eyes but little more 

 than half the width of the fastigium, moderately 

 expanding caudad; fastigium considerably declivent, 

 distinctly broader than long, rounding into the decidedly 

 retreating face; frontal costa regularly expanding 

 caudad, wider even dorsad than the interspace between 

 the eyes, moderately excavate immediately dorsad and 

 ventrad of the ocellus, dorsal portion strongly punctate;
