304 HYMENOPTERA. 



not as strongly as in P. enockii Girault, for instance ; never- 

 theless, at times a row of minute teeth is visible along the 

 under side of the scape and a peculiar sculpture like that de- 

 scribed for P. psecas ; in most specimens however, these 

 are not to be seen. The species is intense black of body, 

 brownish-black with transmitted light. 



3. Polynema biinaculatipeiiiie species nova. 



Normal position. 



Female. — Length, 1.10 mm. Moderate in size for the genus. Char- 

 acterized by being black and having in the fore wings a slight fuscous 

 round spot at the apex and a band of the same crossing the wing at 

 about its middle, 



General color black, the legs and antennae concolorous, suffused 

 with some brownish, only the proximal three tarsal joints, the distal 

 ends of the tibias, the knees, the posterior trochanters and the ab- 

 dominal petiole being pallid and tinged with slight yellowish. Vena- 

 tion dusky. Wings hyaline but a broad slight fumated band crosses 

 the fore wing at its middle (less distinct at the immediate cephalic 

 margin, somewhat more distinct at its middle) and distad nearly at 

 the apical edge is a roundish fumated spot, moderately large. 



Fore wings large, broad bv:t not very much so, its discal ciliation 

 fine and uniform, disappearing at the proximal edge of the fumated 

 band (distad about the length of the antennal club from the venation) 

 and arranged in about from twenty-six to thirty longitudinal lines at 

 the greatest wing width ; the marginal cilia of the cephalic margin 

 short and fine but much longer than the discal cilia, that of the poste- 

 rior margin much longer, yet but moderately long, thus being only 

 about a fourth as long as the greatest wing width and but slightly 

 longer than the longest marginal cilia of the posterior wing. Posterior 

 wings broad, its margins parallel but distad ending in an obtuse point, 

 bearing two distinct lines of discal cilia along each edge and a third 

 line is indicated distad (four or five cilia) near the inner line along the 

 cephalic edge ; these lines abruptly disappear halfway proximad to the 

 venation. The longest marginal cilia of the posterior wing about one 

 and a half times longer than the width of the blade, the latter not 

 noticeably broadened across the apex of the venation. Marginal cilia 

 of the cephalic margin of the posterior wings short, shorter than the 

 corresponding ones of the fore wing, about half as long as the blade 

 of the posterior wing. 



Abdomen ovate, somewhat shorter than thorax (excluding petiole), 

 only the tip of the ovipositor exserted. Petiole cylindrical, stout long, 

 three-fourths the length of the proximal tarsal joint of the caudal legs; 

 metathorax with a narrow acute median carina. Parapsidal furrows 

 complete. Tibial spurs short, single, those of the cephalic legs form-
