In addition to the type and allotype we have before us a male 

 and a female paratj^pe, both from the Misiones and collected 

 by Jorgensen, the former taken April 10, 1910, the latter in 

 December, 1910. Aside from the color features mentioned in 

 the description no noteworthy differences are apparent, except 

 that the paratypic male has but eight spines on the external 

 margin of the caudal tibiae. 



Eurotettix schrottkyi new species (PI. XVIII, figs. 17, IS and 19.) 



Near to E. robustus Bruner," from Chapada, Matto Grosso, 

 Brazil, but differing in the more ovoid tegmina of the male, the 

 more slender caudal femora and the striking coloration, the sut- 

 ural half of the male tegmina and ventral section of the lateral 

 face of the caudal femora of both sexes being solidh' yellow, in 

 strong contrast to the general color. 



Type. — -d^; Puerto Cantera, Paraguay. January. (C. 

 Schrottky; no. 14.) [Academy of Natural Sciences of Phila- 

 delphia, Type no. 5232.] 



.Size medium : form robust : surface dull or very weakly glabrous on the sides 

 and venter of the abdomen, venter of the thorax and on the greater part of the 

 limbs. 



Head with the occiput moderately arcuate, regularlj^ declivent over the 

 interocular section and the fastigium; interocular width of the vertex subequal 

 to the width of the frontal costa at the median ocellus: fastigium moderately 

 longitudinal, its greatest length one and one-half times its greatest width, very 

 shallowly but broadly excavate, margins distinct but low; fastigio-facial angle 

 rounded when seen from the side; interantennal section of face very faintly 

 produced, ventral section of face moderately retreating: froatal costa slightly 

 narrowed at the fastigio-facial angle, weakly expanding to the interantennal 

 region, subequal thence to the median ocellus, weakly expanding thence ven- 

 trad and subobsolete a short distance dorsad of the clypeal suture; dorsal sec- 

 tion of costa punctato-sulcate, sulcate a very short distance dorsad and a 

 greater distance ventrad of the ocellus, margins thick and not defined; supple- 

 mentary facial carinao moderately divergent ventrad: eyes when seen from the 

 dorsum moderately prominent, in basal outline l)road ovate, markedly flattened 

 cephalad and weakly so ventrad, forming an appreciable obtuse ventro- 

 cephalic angle, in depth the eye is equal to one and ono-lialf times the length 

 of the infra-ocular sulcus: antennae missing. 



Pronotum with greatest caudal width of disk contained one and one-half 

 times in the greatest length of the same, the dorsal surface arcuate in trans- 

 verse section, rounding into the lateral lobes without a distinct angle: cephalic 

 margin of disk gently arcuate with a broad though relatively shallow, median
