THE CANADIAN ENTOMOLOGIST. 49 



Colour : vertex fulvous, a pair of approximate spots on tip, and 

 sometimes a spot on either side of disc at base, fuscous. Pronotum pale 

 olive, somewhat washed with fulvous, the posterior disc omitting the 

 margins irrorate with testaceous. Scutellum pale, the apex and a point on 

 each lateral margin ivory white, a pair of spots between these, black, a 

 large spot just inside either basal angle and a pair of dots on disc testace- 

 ous. Elytra milky white, reticulated with coarse pigment lines between 

 the sectors, and washed with brown ; a definite light band at base, widest 

 on the costa, and a narrower, less definite one across the second cross 

 nervure, a heavy fuscous spot before the middle of the sutural margin, a 

 smaller one behind, shut off by a white crescent, and a third at apex of 

 clavus. Apical cells somewhat infuscate. Face fulvous, below pale fulvous. 



Genitalia : ultimate ventral segment of the female over twice the 

 length of the penultimate, the lateral margins narrowing to the slightly 

 produced lateral angles, posterior margin between these angles truncate 

 with a slightly produced, rounding, median lobe. Male valve obtusely 

 angular, the apex produced, plates broad, slightly concavely narrowing to 

 an acute point, four times the length of the valve, the apex curving up. 



Described from seven females from Palmer Lake, Salida, Ridgway, 

 Dolores and Durango, Colo., and one from White Mts., N. Mex., from 

 Prof. Cockerell. 



Eutettix Manitou, n. sp. 



Form and general appearance of modesta. Smaller and more dis-

 3.75 mm.; width, 9 x -5 mm., £ 1 mm. 



Vertex a trifle over half as long as its basal width, evenly rounding 

 or very slightly angulate, disc slightly depressed, passage to front more 

 rounding than in the preceding species. Pronotum more rounding 

 anteriorly than usual in this genus. Elytra very flaring in the female, 

 scarcely so in male, venation as in ocu/ea, claval nerves tied together and 

 to the suture before the middle, central anteapical cell constricted, 

 usually divided. 



Colour: female, vertex pale yellow, a pair of approximate spots at 

 apex fuscous. Pronotum pale olive washed with golden, omitting about 

 three pale stripes. Elytra milky, nervures brown, becoming fuscous 

 before apex and on costa, disc with a testaceous brown cloud which is 

 interrupted by a narrow, parallel margined, transverse light band just 

 before the black-tipped clavus and another irregular band before the
