half the length of the projecting portion of the el^^tra; wings about 

 as long as the elytra. Genital characters as described under the genus, 

 the ovipositor (tig. 76) curved distinctl}^ downward and considerabl}^ 

 longer than the posterior femora. 



Color yellowish brown, in dried specimens usually quite uniform, 

 except the wings, which are piceous, conspicuously contrasting with 

 the brownish colored elytra, which are finely reticulate with lighter 

 veins in both sexes. In some specimens, however, there are conspic- 

 uous chalky white markings, a transverse, faint white stripe following 

 the lower portion of the genaj, another, broader and more conspicu- 

 ous, starting below the eye and passing back along the lower margin 

 of the lateral lobe of the pronotum. In these conspicuously marked 

 specimens another white line runs from the upper portion of the eye 

 to the anterior transverse sulcus of the pronotal disk, and the disk 

 and lateral lobes bear a number of spots and dashes of white and each 

 abdominal segment has an anteriorly directed triangular subdorsal and 

 lateral spot, which, together, form subcontinuous subdorsal and lateral 

 lines extending the entire length of the abdomen. 



Ifeasurements. — Length, pronotum, male, 7.5-9.5 mm., female, 8-10; 

 posterior femora, male, 15-18, female, 16-22.5; elytra beyond the 

 pronotum, male, 4-5, female, 2-5; ovipositor, 22-31; width, pronotum 

 at the middle, male, 4.5-5, female, 4.75-6.5. 



Ty2>f. — In the Scudder collection at Cambridge, Massachusetts. 



Of this species I have recognized a variety which is separated from 

 the typical form in the above table of species. 



The typical form has the posterior femora two times or more than 

 two times as long as the pronotum. The color of both varieties 

 probal)lv exhibit about the same range of variation. The measure- 

 ments of this typical form are as follows: 



Measurements. — Length, pronotum, male, 7.5-9 mm., female, 8-10; 

 posterior femora, male, 15-18, female, 17.5-22.5; elytra, beyond the 

 pronotum, male, 4-5, female, 2-4; ovipositor, 23-31; width, pronotum, 

 male, 4.5-5, female, 4.75-6.5. 



Specimens examined. — Besides the type, a single female from New 

 Mexico, in the Scudder collection, I have studied one male, two 

 females, Durango, Colorado, August 3, one male, Dolores, Colorado, 

 August 2 (Gillette); one immature female, Pindale, Arizona (W. 

 Hough), one female, Morrison, Colorado, and one female, Albu- 

 querque, New Mexico (Cockerell). 



The male specimen from Dolores, Colorado, is v^ry small, the 

 thoracic width being 4.5 mm. and the length of the posterior femora 

 being but 15 mm. The female from Albuquerque, New Mexico, 

 which is in the Scudder collection, is unusually large, the measure-
