THE CANADIAN ENTOMOLOGIST. 47 



milky white, closely and finely irrorate with dull brown, as follows: All of 

 clavus except a narrow strip along basal two-thirds of claval suture, once 

 or twice interrupted and broadened at the end ; a rather narrow oblique 

 strip across corium beyond this and some irregular markings towards the 

 apex, which form two definite spots on the costa. Two pairs of pale 

 spots along the sutural margin of clavus. Face pale yellow, below pale 

 and fuscous. 



Genitalia : ultimate ventral segment of the female nearly twice 

 longer than penultimate, the posterior margin nearly truncate from the 

 rounding angles, with two triangular, slightly protruding, median teeth ; 

 male valve very obtusely triangular ; plates long triangular, their apices 

 attenuate, black, clothed with fine silky hair. 



Described from a pair from Denver, a male from Fort Collins, Colo., 

 and another from Tucson, Ariz. This species is closely allied to scaber, 

 from which the longer vertex, smaller form, lighter colour and absence of 

 distinct band on vertex will easily distinguish it. 



EUTETTIX SCITULA, II. Sp. 



Resembling seminuda, but with the pronotum darkened up. Length, 

 5.5 mm.; width, 1.5 mm. 



Vertex almost parallel margined, twice wider than long, half the 

 length of the pronotum, strongly depressed. Front rather flat, its length 

 and breadth about equal. Pronotum long, its lateral angles distinct, disc 

 but feebly convex. 



Colour : vertex pale creamy yellow, six pale fulvous spots along the 

 anterior margin, sometimes a pair of spots near eyes on basal half. 

 Pronotum dull white, coarsely irrorate with dark fulvous, omitting the pale 

 yellow anterior margin. Traces of three pale stripes. Scutellum pale, the 

 fine dark brown irrorations usually heaviest in a spot just within the basal 

 angles on either side, and another behind the transverse suture. Three 

 spots in a triangle on apical half ivory white; posterior disc light. Elytra 

 milky white, a few coarse brown irrorations along the humeral and sutural 

 margins before the middle, a transverse band behind the middle as in 

 seminuda, but darker brown, and some irregular infuscations towards 

 apex. Face and below pale yellow, pale fuscous arcs on front. 



Genitalia : ultimate ventral segment of female twice the length of 

 penultimate, the posterior margin slightly rounding, with two small round- 

 ingly angular, median teeth ; male valve obtusely triangular ; plates long 

 triangular, their apices attenuate, infuscate.
