sides, especially on the posterior corners, with a strong tendency to 

 reach out from these corners along the hind margin toward the middle 

 line of the segment and occasionally bordering this margin all the way 

 across (one specimen has this segment entirely clothed with yellow 

 pile); segment four usually mostly dark with yellow pile on the ex- 

 treme sides, but sometimes with the yellow pile also extending in 

 toward the middle of the segment on each side, especially along the 

 hind border (one specimen has this segment entirely yellow); segment 

 five mostly dark, usually with more of less yellow pile on the extreme 

 sides ; segment six dark, sometimes with a touch of yellow on the 

 extreme sides; segment seven dark. Venter mostly dark. 



Genitalia. — Outer spatha (fig. 112) with its anterior lateral projec- 

 tions very long and narrow, its anterior margin being deeply and 

 evenly incurved ; side margins broadly and gradually outcurved ; hind 

 margin usually somewhat irregularly, but not very strongly, trilobate ; 

 hind portion of the ventral surface bearing long branched hairs, espe- 

 cially toward the sides and toward the hind margin ; a small fenes- 

 tra usually present, placed on the middle line, some little distance 

 back from the anterior margin. Inner spatha (fig. 59) with its ante- 

 rior margin projecting forward strongly in the middle, the projection 

 being heavily chitinized ; the side margins very abruptly bent inward 

 in front, their posterior portions nearly straight and approaching 

 each other very gradually toward the broadly rounded tip ; apical por- 

 tion of the ventral surface thickly covered with branching hairs ; a 

 large oval fenestra present in the middle, and usually a small one on 

 each side, placed well out in the lateral projection. Clasper with 

 branch of good width, its apex being broadly rounded ; squama very 

 strongly bilobed, the inner lobe comparatively large and prominent 

 and bearing a very heavy brush of branching hairs, and the outer lobe 

 often pointed and slightly hooked at the tip ; volsella pointed, with the 

 posterior half of its inner margin broadly, though not very deeply, 

 incurved. Sagitta with a rather long narrow shaft and foliaceous re- 

 curved head. 



Wings. — Somewhat stained with brown ; somewhat lighter than 

 those of the female. 



Legs. — Dark ; the tarsi more or less ferruginous. 



Dimensions. — Length: female, 16 mm. to 18 mm. ; male, 13 mm. 

 to 17 mm. Spread of wings: female, 38 mm. to 41 mm. ; male, 35 

 mm. to 38 mm. Width of abdomen at second segment : female, 7| 

 mm. to 9 mm. ; male, 5^ mm. to 7 mm. 



Redescribed from five females and twelve males. 



Habitat. — I have seen specimens of this species from Texas 

 (Dallas, Bosque County, Cotulla, Austin, Trinity, Victoria, 

 Goldthwait), Kansas (Baldwin, several specimens) and Ala-
