combined, the very long ovipositor inserted at the base of the 

 abdomen and distinctly projecting beyond the latter's tip for a 

 length equal to about a seventh or eighth that of the slender, 

 tapering abdomen. Stigmal vein merely a very short, foot- 

 like projection from the marginal ; postmarginal vein absent. 

 Posterior wings with moderately long marginal fringes caudad, 

 bearing five longitudinal lines of discal ciliation. Also resem- 

 bling Twnidiclava Girault, but the abdomen is totally differ- 

 ent, the antennal club does not terminate in a spine-like seta 

 and is not so swollen, while the discal ciliation of the fore 

 wing is dense and normal. The distal joint of the club forms 

 over half the length of that segment. One ring joint; no 

 funicle. Cephalic tibial spur present, short and straight. Tar- 

 sal joints rather long. Thorax with a median sulcus. 



Male. Not known. 



In my table of genera Lathromeroides will drop in near 

 Ptery go gramma and Uscana, but the very long, tubular abdo- 

 men, very dense discal ciliation, very short stigmal vein and 

 the distinctly exserted ovipositor readily distinguish it. 



Type : The following species : 



1. Lathromeroides longicorpus, new species. 



Female. Length, i.oo mm. Bright golden yellow, the eyes and ocelli 

 bright garnet, the exserted portion of the valves of the ovipositor and 

 a small, dot-like spot under the stigmal vein deep black, the distal tar- 

 sal joints and the antennae more or less dusky. Wings slightly em- 

 browned under the venation. Legs uniformly pallid yellowish. Inter- 

 mediate joint of cephalic tarsus shortest, the other two sub-equal; long- 

 est tarsal joint is the proximal joint of intermediate legs. Wings mod- 

 erate in width, convexly rounded at apex. Proximal two joints of an- 

 tennal club wider than long.
