THE CANADIAN ENTOMOLOGIST. 151 



against the carinas outside, black. Tegulas smoky brown, scutellum 

 brownish or pale, with four large fuscous spots. Elytra milky white, 

 clouded with brown along the light-dotted nervures, a pair of slightly 

 oblique fuscous stripes towards the apex in the long-winged examples. 



Described from twenty-four examples from various points in 

 Colorado. Readily separated from all other species by the broad form 

 and short process. 



Cixii/s cuttus, n. sp. 



Resembling stigmatus without basal band, smaller and narrower. 

 Narrower than pini, with a longer vertex. Length: ^ 6 75 mm., r? 5 

 mm.; width 2 mm. Vertex longer than breadth at base, acutely 

 triangular at apex, with the bounding carina? distinct, apex distinctly 

 overhanging front. Front rather narrow, enlarged over the antennae 

 beyond the line of the marginal curve, median and lateral carinas distinct 

 as in cohepeum. Elytra very long and narrow, parallel-margined. 



Colour : black, the carinas of front and vertex, all the pronotum 

 except the area behind the eyes, the tegulas and the carinas of scutellum, 

 light. Sometimes the carinas on front and scutellum are reddish. Elytra 

 milky, sometimes slightly clouded with smoky and with a pair of smoky 

 spots before the middle and another faint one inside the stigma. Stigma 

 small and oblique. 



Male pygofers short, with the posterior margin deeply notched, the 

 apex of the notch with a short tooth. Styles about equalling the 

 pygofers, slender at base, broadening out into a slipper-shaped apex, with 

 the toe out. Anal tube without teeth below. Entire genitalia black. 



Described from ten specimens from Calif, two from Kans. and nine 

 from Colo. The elongate vertex and narrow form will readily separate 

 this from any other described species. 



liar us aridus, n. sp. 



Resembling panzeri, but more elongate, as large as j-lineatus, but 

 with longer and narrower elytra. Length : $ 7.25 mm., £ 6.5 mm.; 

 width 3 mm. 



Vertex shorter and broader than in ^-/ineatus, but little longer than 

 wide, parallel-margined on posterior half, then rounding to a blunt apex, 

 posterior margin angularly notched, face much broader than in 5-lineatus, 

 nearly flat transversely, with distinct carinas. Elytra long and narrow, 

 with a rather small stigma.
