the Biologia follows Signoret in his use of tripunctata, but 
as suggested by Van Duzee, Ent. News Y, p. 155, this is 
evidently a mistake and refers to a distinct species which 
should be called nigrifctsciata Walk., and which should not 
only include pallida and albida but also uniguttata 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 tripunctata. As 
described and figured by Signoret nigrifasciata should be 
close to venusta Stab, which belongs to the gothica. group 
with the retracted face.

Tettigonia hartii Wood. MSS. 
Form and structure of tripunctata , but 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.; c? 8.75 — 4 
mm; wfidth, 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 clyp- 
eus below, about twelve pairs of pale arcs on either side. Lorse 
and g ersd 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, claval 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
