296 HYMENOPTERA. 



in xylol-balsam. It differed from the Illinois specimen in 

 having a more or less obscure fuscous cloud crossing the 

 fore wing about midway between the distal end of the mar- 

 ginal vein and the wing apex. 



5. AnagTUS sag'a species nova. 



Normal position. 



Female.— Length, 0.55 mm. Moderate in size for the genus. 



Difiering at once from all other species of the genus by being wholly 

 black in color, in having the body of the abdomen narrowed at the 

 base as in petiolate genera and having the antennal joints all short, 

 none of them longer than the pedicel. The fore wings though narrow 

 are densely ciliate, the cilia fine. 



General color dusky black, the legs and antennas dusky ; portions of 

 coxae, knees, tips of tibiae, trochanters and proximal three tarsal joints 

 pallid, the diatal tarsal joint dusky; wings hyaline, venation pallid 

 dusky. Eyes garnet. 



Fore wings normal to the genus, their caudal margins straight, the 

 cephalic margins convexly curved, the dilatation near base caudad 

 prominent, the wings somewhat as in puella but narrower, distinctly 

 broader than in artnatus or epos ; discal and marginal cilia fine, the 

 latter distinctly longer than the greatest wing width, the longest being 

 about a fourth longer; the discal short and fine, distributed uniformly, 

 about twelve longitudinal lines across the widest portion of the blade. 

 Posterior wings narrow, straight, the marginal fringes of the caudal 

 margin five or more times longer than the width of the wing blade, not 

 more than two-thirds the length of the longest marginal cilia of the 

 fore wing, those of the cephalic margin short, just slightly longer than 

 the wing blade is wide. Discal cilia of posterior wings distinct and 

 apparently normal, there being no midlongitudinal line of them. Legs 

 rather less slender than usual, the coxse all obconic and short, the 

 femora short and obclavate, the posterior tibiae slenderer and longer 

 than the others, distinctly longer than the caudal femora, the cephalic 

 femora and tibiae subequal in length, the latter curved, the former 

 obclavate; tibial spurs single, short, small, the cephalic one forming a 

 strigil, curved and forked but yet small ; joints of cephalic tarsi short, 

 the proximal joint there thick and short, yet twice the size of either of 

 the following joints ; the proximal joint of the caudal tarsi moderately 

 long, slender, a third longer than the corresponding joint of the 

 cephalic tarsi and twice the length of the same joint of the intermediate 

 tarsi. Parapsidal furrows complete, widely separated ; abdomen short, 

 ovate, the ovipositor not at all exserted, proximad the abdomen nar- 

 rowed as if petiolate, about equal to the thorax in length. Vertexal 

 carina present, separating the lateral ocelli from the eye margins. 



Antennae 9-jointed, the joints all short, Scape and pedicel nearly
