(anus BORELLIA Rehn. 



Borellia Reus, Proc. U. S. Nat. Mus., XXX, p. 379 (1906). 



According to Rehn this genus is quite closely related to Staurorhectus 



Giglio-Tos. Its representatives are confined, so far as known, to 



southern Brazil. 



42. Borellia carinata Rehn. 



Borellia carinata Rehn, Proc. U. S. Nat. Mus., XXX, pp. 379-381 (1906). 



Habitat. — The large series of specimens at hand are labeled "Cha- 

 pada," " Chapada near Cuyaba, Matto Grosso, Brazil," and "Rio de 

 Janeiro." They were taken during the months of May, June, July, 

 and October (H. H. Smith). 



Genus Euplectrotettix Brunei'. 

 Euplectrotettix Brvner, Locusts of Argentina, pp. 38, 39 (1900). 



A genus somewhat closely related to Scyllina Stal, but quite readily 

 separable from the latter by the pronotal characters. The species are 

 several in number and occur from southern Brazil southward. 



43. Euplectrotettix ferrugineus Bruner. 



Euplectrotettix ferrugineus Bruner, Locusts of Argentina, pp. 39-40 (1900). 



Habitat. — Several males are at hand from Chapada, Brazil, where 

 they were taken in September by H. H. Smith. 



44. Euplectrotettix scyllinaeformis sp. nov. 



Robust, grayish, mottled with brunneo-ferruginous and fuscous, 

 vertex without the least trace of lateral foveolae, the lateral carina? of 

 pronotum present only on the anterior edge of the front lobe. Hind 

 tibia? red, without pallid basal annulus, the external margin ten-spined. 



Head large, a little wider than the anterior portion of the pronotum, 

 the occiput evenly rounded and somewhat elevated above the general 

 level of the disk of pronotum; eyes of moderate size, not prominent, 

 rather widely separated above; the vejtex short, blunt, nearly twice 

 as wide as long and transversely deeply Innately sulcate, the area 

 usually occupied bv the lateral foveolae coarsely punctulate; frontal 

 costa roundly confluent with the vertex, of nearly equal width through- 

 out, not prominent, in no manner sulcate, rather uniformly punctulate, 

 even below the ocellus. Antennae filiform, rather heavy, and about 

 as long as the head and pronotum combined. Pronotum gently 

 constricted at middle, the posterior margin but little wider than the
