4. PHAEDROTETTIX, newgenus. 



(<pa/5/3o?, bright; rcrrzc, grasshopper.) • ' . 



Body small, comjjact, distinctly largest at the metathorax, 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, thefastigiuii) 

 descending rapidly and the face retreating somewhat; eyes moderately 

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

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

 as broad, scarcely longer than the intraocular portion of the genac: 

 interspace between the eyes almost ecpially narrow in both sexes, con 

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

 subequal, i)ercurrent, sulcate; antennae slender, of similar length in 

 the two sexes, but very little longer than head and i)ronotum together. 

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

 flaring considerably throughout, otherwise i)arallel-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 peri^urrent median 

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

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

 augulate, being bent forward laterally, its posterior sulcus similarly 

 bent or sinuate, its anterior ulcus rather remote from the front niargin, 

 Prosternal spine erect, con' al, subappressed; inters})ace between meso 

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

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

 approximate in both sexes. Tegmina linear, lateral, about as long a> 

 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 n ale 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 ai* 

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

 anal plate; cerci laminate, subfalcate; funuila subobsolete. 



A single species is known, coming from Mexico and southern Texa>

Fuscous above, luteo-fuscous below. Head livid fuscous, flecked \w
