Bruner: Saltatorial Orthoptera. 11 



Specimens of both sexes of a rather slender rugose-granulose grouse- 

 locust coming from the Province del Sara, Bolivia, are referred to 

 Bolivar's Paratettix peruvianus. They were taken at the same time 

 and locality as the following insect, which has been determined as 

 Allotettix chapadensis described by me (see Annals Car. Mus., VII, 

 p. '117). The present lot was taken by J. Steinbach. C. M. Ace. 

 No. 5573. 



9. Allotettix chapadensis Bruner. 



Allolettix chapadensis Bruner, Ann. Carnegie Mus., VII, pp. 115, 117 (1910). 



All the specimens in the present collection, which are referred to 

 this species, come from the Province del Sara, Bolivia. They were 

 taken by J. Steinbach in October and December, and were found at 

 an elevation of about 350 meters above sea-level. Both sexes are 

 represented. C. M. Ace. No. 5058. 



10. Allotettix sp.? 



In addition to the three species of Allotettix recorded above there 

 is a single male of what seems to be a fourth species at hand. It was 

 taken at Las Juntas, in the Department of Santa Cruz, Bolivia, at an 

 elevation of 250 meters above sea-level, in December, 1913, by J. 

 Steinbach. C. M. Ace. No. 5060. 



It is not as rugulose as is usually the case in representatives of the 

 genus, but is instead remarkably coarsely granulose, and has the 

 median carina of the pronotum quite prominent and of nearly equal 

 height throughout. The vertex is also a little more advanced in 

 front than is usual in representatives of this genus. I refrain, in 

 view of the paucity of the material, from giving it a specific name. 



Genus Rytinatettix Hancock. 



Rytinatellix Hancock, Trans. Ent. Soc. Lond., 1908, p. 418 (1908); Rehn, Trans. 

 Amer. Ent. Soc, XLIII, p. 343. 



As shown by Mr. Jas. A. G. Rehn (/. c.) Hancock created the genus 

 Rytinatettix for the reception of the Prototettix fossulatus of Bolivar 

 and the Tctrix lobiilata of Stal, as well as the Paratettix borellii of 

 Giglio-Tos. 



II. Rytinatettix fossulatus Bolivar.
