the Biologia follows Signoret in his use of fripuiicfata, but 

 as suggested by Van Duzee, Ent. News V, p. 155, this is 

 evidently a mistake and refers to a distinct species which 

 should be called nifjrifasciaftf Walk., and which should not 

 only include pallida and alhida but also loiigattata and 

 Candida of Walker. The markings on the head and pro- 

 notum are quite different and the genitalia as described by 

 Signoret could not apply to the true tripiDictata. As 

 described and figured by Signoret nigrifasciaia should be 

 close to reniista Stal., which belongs to the got h lea group 

 with the retracted face.

Tettigonia hartii Wood. MSS. 



Form and structure or fripandafa, hut shorter and much 

 stouter built, especially the head. Female slaty gray, 

 median line of front and nervures lighter. Male much 

 smaller, shining black. Length, 9 4.5 — 15 mm.; <?3.75 — 4 

 mm; width, 9 1.25 mm.; <? scarcely one mm. 



Vertex obtusely rounding, conical, two-thirds the length of the 

 pronotum, twice wider than long, the ocelli placed near the anterior 

 margin and on the inner margins of depressed areas. Pronotum 

 broad, flat. Elytra broad, venation similar to bifida^ a cross nerv- 

 ure forming the inner anteapical cell, the second fork of the outer 

 sector rarely closed behind to form the outer anteapical cell, usually 

 curving away to the costa. Outline of face as seen from side, 

 rounding, face very deep. 



Color; female; vertex pale yellowish or brownish, the ocelli and 

 a pair of spots within and behind them, on the posterior margin 

 black. Ocelli often with light circles; in front of the ocelli the vertex 

 is abruptly darker, except for the light spot on apex. Front piceus 

 or brown, a definite median white stripe which enlarges above to 

 form a spot on apex of vertex and often extends onto the dark elyp- 

 eus below, about twelve pairs of pale arcs on either side. Lorte 

 and gen 03 pale. Pronotum slaty or brownish, the anterior margin 

 pale, broadening out behind the eyes where it enclosed a black 

 spot; sometimes a pair of spots on the anterior sub-margin behind 

 the basal pair on the vertex. Scutelium pale, a triangular spot 

 within either basal angle. Elytra slaty gray, the nervures pale yel- 

 low, elaval margins often lined with light blue. Male; shining black, 

 often with circles around the ocelli and the apex of scutelium pale, 

 the spot on apex of vertex white, the median line on front black, 

 the rest of front tinged with rufous, margin of genae pale. 



Genitalia; female segment about half longer than the preceding 

 one, posterior margin truncate, slightly incised either side the middle
