NO. 2008. NEW SPECIES OF THT8AN0PTERA— MORGAN. 21 



spines. Fore vein runs very close to costa to tip of wing, hind vein 

 nearer costal than anal margin of wing, and joins fore vein at end of 

 first fifth of length of wing, thence running to tip of wing. Hind vein 

 with one or two spines; the anastamosed veins bear three or four 

 minute almost colorless spines; one spine on hind vein very near junc- 

 ture of veins, one spine upon the anastamosed veins always near the 

 tip of the wing. Hairs composing posterior fringes of both wings 

 long, slender, straight and light colored. Legs fighter colored than 

 body, quite long and slender; tarsi apparently only one-segmented; 

 fore and middle tibiae unarmed; each hind tibia bears two slender 

 colorless spines at its inner extremity; other spines upon hind tibia 

 few, and minute. 



Abdomen scarcely wider than prothorax, almost cylindrical, widest 

 at fifth segment, thence tapering very gradually to the ninth segment; 

 ninth segment considerably narrowed behind; tenth segment longer 

 than wide, widest at base, sides convex, tip broadly rounded. Tip 

 of tenth segment dorsally bears four slender, colorless spines, and 

 midway of segment on each side stands a spine similar to the apical 

 ones. Ninth segment bears dorsally four slender colorless spines at 

 the apex and two similar spines on the lateral margins apically. 



Described from numerous females taken at Dallas, Texas, Septem- 

 ber 26, 1910, by W. D. Pierce, after whom the species is named. No
