48 THE CANADIAN ENTOMOLOGIST. 



Described from numerous specimens from Fort Collins, Pueblo, 

 Salida and Grand Junction, Colo. This species is most closely related to 

 seminuda, but the genitalia and pronotal band will at once distinguish it. 



EUTETTIX PULLATA, 11. Sp. 



Form and general appearance of scitula, but darker, approaching 

 perelegantis in shade, but lacking the definite pattern of that species. 

 Length, 5.5 mm. ; width, 1.5 mm. 



Vertex two and one-half times wider than long, half the length of the 

 pronotum, transverse depression very shallow, front broad and fiat. 

 Pronotum rather flat, scutellum transversely depressed, the apex swollen, 

 elevated. 



Colour : vertex white or pale yellow, a narrow fuscous line just in 

 front of eyes, in front of which are four dots, and behind which are three 

 large irregular, sometimes confluent, irrorate patches. Pronotum light, 

 coarsely and somewhat sparsely irrorate with brown. Scutellum with a 

 brownish fuscous patch just within each corner, disc pale or orange yellow. 

 Elytral pattern as in scitula, but broader and darker ; clavus entirely 

 reticulated except for two transverse bands, one at base and a broader, 

 interrupted one before the middle, the white area of the corium with a few 

 dots or reticulations. 



Genitalia : ultimate ventral segment of female three times the length 

 of the penultimate, the posterior margin broadly rounding, the median 

 fourth triangularly excavated, the apex of this excavation broad, rounding 

 or bidentate ; male genitalia as in scitula, valve obtuse, plates long 

 triangular, the margins straight, tips attenuate. 



Described from eighteen specimens from Manitou (Van Duzee), and 

 five from Colorado Springs and Salida, Colo., by the author. 



EUTETTIX MUNDA, n. sp. 



Form of jucunda, Uhler, longer and redder. Resembling costamac- 

 ulata, Van D., but with thecosta reticulate. Length, $ 6 mm., <? 5 mm.; 

 width, 1.75 mm. 



Vertex sloping, transversely depressed, parallel margined, three times 

 wider than long, two-fifths the pronotal length; front longer than its basal 

 width, the margins evenly narrowing to the clypeus. Elytra broad, much 

 longer than the body, the apices flaring ; venation distinct, the second 

 cross nervure present, joining the fork of the inner branch of the first 

 sector in nearly a straight line, the inner continuation of this fork leaving 

 this line at about the middle.
