40 THE CA.NADIA.N ENTOMOLOGIST. 



each plate is a long filament-like appendage resembling that commonly 

 met in Scaphoideus. 



Described from a single male specimen from Cuernavaca, Mex. 

 (O. W. B.) 



Cklorotettix tunicata, n. sp. — Form and general appearance of 

 Balli, vertex as '\x\ ^albanata. Length, 7 mm.; width, 1.25 mm. 



Vertex half longer on middle than against eye, twice wider than long, 

 disc convex, front and vertex evenly rounded except at apex, which is 

 slightly conical. 



Colour pale green, elytra subhyaline, greenish. 



Genitalia : ultimate ventral segment of female half longer than 

 penultimate, lateral angles rounding, posterior margin roundingly emar- 

 ginate, one-third the depth of the segment, sometimes slightly notched in 

 the middle, either side of which there is a brown cloud ; male valve broad, 

 slightly longer than the ultimate segment, obtusely angulate, plates broad 

 at base, roundingly narrowing to a very obtuse, almost truncate, apex, 

 together the shape of a blunt-pointed spoon, convex below with a marginal 

 fringe of coarse spines. 



Described from three females and three males from Onaga, Kan. 

 (Crevecouer). This species may be readily separated from any other 

 described by the male plates. 



Cklorotettix ?mdata, n. sp. — Resembling stolata in form and colour ; 

 the vertex is more angled and the fulvous reflection less prominent. 

 Length, 7.5 mm.; width, nearly 2 mm. 



Vertex twice longer on middle than against eye, slightly conically 

 pointed, front shaped as in lusoria, loras long and narrow. Elytra long, 

 slightly flaring in the middle, appressed behind. 



Colour : pale green, an orange cast on face and vertex, a slightly 

 brownish or fulvous cast on pronotum and elytra, elytra subhyaline, the 

 nervures indistinct. 



Genitalia : ultimate ventral segment of the female very short, scarcely 

 as long as the penultimate segment; posterior margin divided into four 

 lobes by a narrow slit in the middle and a pair of broad, shallow notches 

 a little more than half way towards the sides, the margin thin, the plates 

 visible at the base of the pygofers ; male valve narrow, obtusely angular, 

 as long as the ultimate segment, plates broad at base, three times the 

 length of the valve, gradually narrowing to the acute slightly produced 

 tips.
