Bruner: Saltatorial Orthoptera. 63 



In color this specimen approaches surinama and in size is slightly 

 larger than the largest specimen of surinama as recorded by Rehn 

 (Proc. Acad. Nat. Sci. Philad., May, 1918, p. 172) where he mentions 

 the variability of the species. 



Head large, the occiput short, smooth, bullate; vertex between 

 the eyes a very little greater than the diameter of the basal antennal 

 joint; the fastigium of the vertex short, depressed, broadly sulcate at 

 middle, the sulcation gradually, roundly, and faintly merging into 

 that of the frontal costa, which latter is rather prominent above 

 between the bases of the antennae, but quickly lowers at the ocellus 

 and below, continuous but inconspicuous to the clypeus. Antennae 

 filiform, quite coarse, about one-half longer than the head and pro- 

 notum combined. Pronotum glabrous, but quite closely punctulate 

 and rugose, save at its sides between the hind sulcus and the anterior 

 margin, where the surface is almost smooth; anterior margin a little 

 advanced upon the occiput, the middle angulately emarginate, the 

 hind border broadly angulate, but with the apex triangularly emar- 

 ginate, the transverse sulci profound; the median carina rather coarse, 

 cut by all three sulci. Tcgmina of moderate width, the costal margin 

 somewhat broadly and shallowly lobate near the base, reaching well 

 beyond the tip of the abdomen, apex rounded. Apex of the abdomen 

 slender, the last ventral segment and subgenital plate pale, smooth, 

 and together forming a differentiated area, appearing quite different 

 from the other ventral portion and directed obliquely upward, the 

 sub-genital plate on its outer half compressed to about one-third of 

 its basal width, the apex narrowly prow-shaped, entire; cerci elongate, 

 abruptly bent both upwards and inwards, the slender finger tapering 

 but little, so that the two by bowing inwards touch their tips above 

 the apex of the supra-anal plate, which latter is formed somewhat 

 like that in other members of the genus, as are also the lobes of the 

 preceding segment in advance of the bases of the cerci. Prosternal 

 spine rather long and slender, evenly conical, acuminate. Meso- 

 sternal lobes separated by a space a little less than the width of the 

 lobes themselves. 



General color dark olive-green with the usual longitudinal pallid 

 lines and the broad band of black on the sides of head, pronotum and 

 pleura separating these lines of yellow as described for both T. surin- 

 ama and T. phila. Base of the anterior and median femora tinged 

 with coral-red; the apical lobes or geniculae of the middle femora
