This species has never been described but as may be inferred has 

 been mentioned several times in the literature of economic ento- 

 mology. I describe it so that the name will not be lost. 



Normal position. 



Female. — Length, 0.75 mm. ; small for the genus but visible to naked eye. 



General color dusky black, the whole of the legs excepting the distal tarsal 

 joints and the antennae excepting the enlarged clubll pallid to lemon yellow; 

 distal tarsal joints and antennal club concolorous with the general body color ; 

 distal three funicle joints and the cephalic coxa; with some tinges of dusky on 

 one aspect ; venation pallid to dusky ; wings wholly hyaline. Eyes dark. Abdom- 

 inal petiole concolorous with the legs. 



Fore wings narrow and graceful, their proximal half slender, the blade 

 not enlarging until the end of that half is reached when it gradually enlarges 

 to the shape of a slender paddle, the longest marginal fringes distinctly longer 

 than the greatest wing width, at least by a fourth, long and slender, the wing 

 blade obtusely pointed, the apex dome-shaped, the wing from 7 to 8 times 

 longer than broad, with moderately dense, moderately fine discal ciliation (about 

 9 lines but varying occasionally to only 5), which disappears proximad some 

 distance out from the marginal vein ; marginal fringes comparatively long, 

 marginal vein bearing 2 setse from its surface, normal. Posterior wings narrow, 

 straight, slender, linear, the marginal fringes of the posterior margin long and 

 slender, the longest of them 5 or 6 times longer than the wing is wide but 

 by far not half so long as the longest fringes of the fore wing, those of the 

 cephalic margin moderately short, delicate, inconspicuous, slightly longer than 

 the wing is wide. Discal ciliation of the posterior wing sparse, apparently 

 irregular, apparently 'a single line of long, slender setse, far apart and alter- 

 nating from one margin to the other but actually consisting of a single line 

 of long cilia along each margin ; posterior wings with a dusky appearance but 

 really clear. 



Tarsi 4-jointed, the proximal joint of the posterior tarsi longest but some- 

 what shorter than the combined lengths of the distal three joints, more than 

 twice the length of the second joint, the other three joints subequal ; the 

 proximal joints of the intermediate and cephalic tarsi shorter in relation to 



* As I shall show elsewhere, this species is the Ooctonus longipcs of Ash- 

 mead, Canadian Ent., XIX, 1887, p. 192. Thus, the name will have to be 

 Polynema longipes (Ashmead).
