204 THE CANADIAN ENTOMOLOGIST. 



Genitalia : ultimate ventral segment of the female three times the 

 length of the penultimate, angularly excavated from the acute lateral 

 angles half way to the base in the middle, from which arises a strap-like 

 tooth, nearly equalling the lateral angles, its apex rounded; male valve 

 not as long as the ultimate segment, very obtusely triangular, plates broad 

 at base, triangularly narrowing to one-third their original width, then ex- 

 tending as acutely tapering up-turned points. 



Described from numerous specimens taken at Pueblo, Colo. 



Eutettix stricta, n. sp. — Form of insaiia, but narrower, pale yellow, 

 with a golden reflection, especially in the males. Length, 5 4 mm., $ 

 3.5 mm. 



Vertex nearly parallel margined, almost twice wider than long, as 

 wide as the pronotum is long, the surface slightly depressed, bluntly 

 rounding to the front, face g.s in i/isa/ia ; elytra rather long, narrowing 

 behind, veins on clavus not united. 



Colour: vertex orange or greenish yellow, sometimes a pair of spots 

 behind the apex, face lemon yellow, front with about seven short brown 

 arcs, the up])er pair very oblique ; pronotum olive or yellowish ; scutel- 

 lum orange, a pair of brown spots on the disc; elytra greenish or golden 

 subliyaline ; below lemon yellow, rostrum orange. 



Genitalia : ultimate ventral segment of the female two and one-half 

 times the length of the penultimate, the lateral margins narrowing posteri- 

 orly, posterior margin truncate, with a broad just noticeable median pro- 

 jection ; ovipositor rather long, orange ; pygofers narrow, greenish ; male 

 valve very short and broad, about half the length of the ultimate segment, 

 plates very broad at base, long triangular, with the acute apices produced 

 and coloured bright orange. 



Described from numerous examples collected in Ariz, by Dr. Kunze. 



Deltocephaius grammicus, n. sp. — Form oi albidus nearly, but longer 

 and narrower. Lemon yellow, with six brown stripes on pronotum and 

 elytra. Length 5.25 mm.; width 1.25 mm. 



Vertex flat, roundingly right angled, a fifth longer than its basal 

 width, over half longer on its middle than against the eye, a fifth longer 

 than the pronotum ; face making an acute angle with the vertex, front 

 very narrow, resembling a Platymetopius ; elytra long, flaring, venation 

 similar to that o{ i input ans, obscured by the colour lines, veins on clavus 

 coalescing for one-third their length.
