 Tettigidea paratecta n. sp. 



Type: 9 ; Misiones, Argentina. February 1, 1911. (P. Jor- 

 gensen.) [Acad. Nat. Sci. Phila., type No. 5,217.] 



Belonging to the section of the genus including chichimeca Saussure, 

 tecta Morse, annulipes Bruner and scudderi Bolivar. From chichimeca 

 and scudderi the present form can be readily distinguished by the 

 tectate dorsum, scudderi also having the femora narrower; from 

 annulipes the new form can be separated by the non-glabrous surface 

 and the blunter and much less produced vertex, no approach being 

 found to the type of T. prorsa, the vertex of which that of annulipes 

 is said to greatly resemble. From tecta, its closest ally, paratecta 

 can be separated by the more elevated and arcuate median carina 

 of the pronotum, the more regularly angulate cephalic margin of the 

 same, the less decidedly lineato-rugulose dorsum of the pronotum, the 

 less projecting vertex, the less thickened margins of the frontal costa,. 

 the more lanceolate tegmina and more finely sculptured pagina of the 

 caudal femora. 



Size medium (for the genus); form robust; surface rather evenly 

 chagrinous. Head with the greatest width contained about one and 

 one-third times in the depth of the same; fastigium with the carina 

 regularly arcuate when seen from above, obsolete immediately 

 laterad of the median carina, width of the fastigium subequal to that 

 of one of the eyes; median carina of the fastigium prominent, pro- 

 jecting moderately cephalad of the lateral carina of the fastigium, 

 when viewed from the side strongly arcuate and passing into the
