 Normal position. 



Female. — Length, 0.50 mm., average, somewhat variable. Moder- 

 ate in size for the genus. 



General color gamboge but variable somewhat in shadings ; bright, 

 uniform. Body shaded with dusky above on thorax and abdomen; 

 sometimes pallid yellow and thus shaded and sometimes with some 

 orange. Legs and antennae concolorous or the flagellum may be dusky 

 (except proximal funicle joint ; that, the scape and pedicel pallid yel- 

 low); valves of ovipositor dusky. Ovipositor itself concolorous. Eyes 

 dark reddish. Mouth fuscous. The abdomen may be wholly dusky 

 and with a faint striped appearance due to the pale intersegmental 

 spaces. Wings hyaline, excepting a slight fuscation proximad. 



Fore wings as in Polyiiema longipes (Ashmead), that is very narrow 

 and graceful with very long marginal cilia; fore wing curved, cla- 

 vate, narrow proximad, very gradually, uniformly enlarging distad, 

 then more rapidly enlarging to a pear-shaped apical head, its discal 

 ciliation sparse, only about five or six longitudinal lines just before 

 apex, the central one of which is longer, extending proximad nearly to 

 the base of the marginal vein ; the individual cilia are moderate in 

 size, not short nor minute. The apex of the fore wing is bluntly coni- 

 cal. The longest marginal cilia of the fore wing are one and three- 

 quarters longer than the greatest wing width, somewhat unusual for 

 the genus ; they are distinctly longer than the longest cilia of the poste- 

 rior wings. Marginal vein of fore wing moderate in length about six 

 or seven times longer than wide and free and curved distad. Poste- 

 rior wings very narrow and slender, nearly as long as the fore wings 

 (reaching out to widest point of the fore wing), slightly curved, acu- 

 minate, acute at apex, without discal cilia excepting for a paired row 

 along each margin, each line somewhat separated. Hooklets three in 

 number. Marginal cilia of the caudal margin of the posterior wings 

 very long, about three and a half times longer than the wing blade is 

 wide but as stated shorter than the longest cilia of the fore wing. 



Parapsidal furrows complete, the mesoscutum subquadrate. Abdo- 

 men sessile, short, conic-ovate, the valves of the ovipositor distinctly 

 slightly exserted (not longexserted as stated in the original description 

 of this species, but only exserted to the length of the second funicle
