ico. Having only a male from Columbia, received from Hofrath Brun- 

 nervon Wattenwyl, I am compelled to base my description and figure 

 upon that alone. Giglio-Tos reports it from Paraguay. 



4. PHAEDROTETTIX, new genus. 

 ((paidpoS, bright; rsm, grasshopper.) 



Body small, compact, distinctly largest at the inetathorax, sparsely 

 pilose. Head a little prominent and, with the eyes, nearly as broad as 

 the posterior portion of the pronotum, at least in the male, the vertex 

 moderately convex, slightly elevated above the pronotum, thefastigium 

 descending rapidly and the face retreating somewhat; eyes moderately 

 large, moderately prominent, more prominent in the male than in the 

 female, broad oval, half (female) or less than half (male) as long again 

 as broad, scarcely longer than the infraocular portion of the geuae; 

 interspace between the eyes almost equally narrow in both sexes, con- 

 siderably narrower than the frontal costa. which is not very narrow, 

 subequal, percurrent, sulcate; antennae slender, of similar length in 

 the two sexes, but very little longer than head and pronotum together. 

 Pronotum very feebly flaring in front to receive the head, the metazona 

 flaring considerably throughout, otherwise parallel-sided, compressed, 

 the dorsal surface transversely convex, passing insensibly into the ver- 

 tical lateral lobes with no lateral carinae, both front and hind margins 

 truncate, the latter feebly and roundly emarginate, a percurrent median 

 carina; prozoua sparsely punctate, less than twice as long as the closely 

 punctate metazona, at least in the male, its middle transverse sulcus 

 angulate, being bent forward laterally, its posterior sulcus similarly 

 bent or sinuate, its anterior sulcus rather remote from the front margin. 

 Prosternal spine erect, conical, subappressed ; interspace between rneso- 

 sternal lobes of male subquadrate, slightly longer than broad, of female 

 distinctly transverse, almost as broad as the lobes; metasterual lobes 

 approximate in both sexes. Tegrnina linear, lateral, about as long as 

 the prozona. Fore and middle femora tumid in the male; hind femora 

 rather long and slender, the hind tibiae with nine spines in the outer 

 series. Extremity of the male abdomen subclavate, upturned, bluntly 

 rounded, but with a slight apical tubercle formed partly by the com- 

 pression of the subgenital plate, the lateral margins of which are 

 straight throughout, and at apex do not surpass the tip of the supra- 

 anal plate; cerci laminate, subfalcate; furcula subobsolete. 



A single species is known, coming from Mexico and southern Texas. 



PHAEDROTETTIX AUGUSTIPENNIS, new species. 



(Plate II, fig. 7.) 

 Pezotettix anf/ustipennis BRUNER!, MS. 



Fuscous above, luteo-fuscous below. Head livid fuscous, flecked and 

 more or less punctate with fuscous, the vertex (except a livid stripe 

 following the upper edge of the eye and passing backward) and a broad
