Three paratypic females taken in April and June have also been 

 examined. No important difference between these and the type has 

 been noticed. Several of the specimens have one or both of the caudal 

 femora with ten spines on the lateral margins, while the intensit}'^ of 

 the dorsal green Irar is subject to variation. The paratypic specimens 

 have the lateral aspects of the head paler and greenish instead of dark as 

 in the type, leaving a distinct bar extending from the dorsum of the 

 eye back to and over the dorsum of the pronotum, 



STEREOTETTIX,« new genus. 



This genus is closer related to BoreUia Rehn, than any other genus 

 of the group. From this it differs in the position of the lateral fov- 

 eola?, the presence of distinct parallel lateral carinte on the pronotum, 

 in the very narrow discoidal tield of the tegmen, in the much more 

 transverse interspace between the mesosternal lobes and the more 

 elongate and strongly sulcate supra-anal plate of the male. 



Superticially, this genus much resembles Euplectrotettlx Bruner, a 

 member of the Scyllini. 



Type. — Stereotettir jxiralog lutes., new species. 



STEREOTETTIX PARALOGISTES, '' new species.

 (H.'h. Smith.) [U. S. Nat. Mus. No. 9490.] 



Size very siuall; form moderately robust. Head slightly shorter 

 than the pronotum; occiput gently arcuate, in the female a little more 

 elevated dorsad of the level of the pronotum than in the male; fas- 

 tigium extending beyond the eyes a distinct slightly or considerably 

 less than the narrowest portion of the interocular region, the angle 

 rectangulate in the male, subrectangulate in the female, the dorsum 

 with an apical crescentic depression which leaves the margins in 

 relief; lateral foveol^ ventrad of the fastigial margin and not visible 

 from the dorsum, except the sections toward the frontal costa, 

 elongate lanceolate, very deeply impressed; angle of the face con- 

 siderably retreating, the apex truncate, forming a right angle with 

 the fastigium; frontal costa rather acute dorsad, regularly expanding
