68 HYMENOPTERA. 



Genus POROPCEA Foerster. 

 1. Poropoea attelaborum species nova. 



As both sexes of this genus are well known and do not 

 differ excepting in the secondary characters present in the 

 antennae and abdomen and also since the host of this species 

 is definitely known I do not hesitate in describing it from 

 this single male specimen. 



Normal position. 



Male.— Length, 1.05 mm. ; moderately large, short, robust. Gen- 

 eral color shining black ; meson of scutellum yellowish, forming an 

 acuminate sagittate yellow mesal area with its truncate base cephalad 

 and with its slender acute apical end caudad. Eyes dark garnet. 

 Head wider than the thorax, the vertex thin, acute, wide, the meso- 

 notum large, nearly as long as the remaining portions of the body 

 combined, slightly convex, with no median carina or impression, the 

 median line smooth, the deep parapsidal furrows very widely sepa- 

 rated, in the dorso-lateral aspect. Scutellum distinct, rounded in out- 

 line, convex, but shorter than the long scutum. Dorsum of the thorax 

 distinctly reticulated and shining, the sculpture moderately coarse, 

 not punctate. Abdomen very short, triangular, acute, nearly hidden 

 (dorsal aspect); short, subquadrate (lateral aspect). The proximal 

 two tarsal joints and the apex of the tibiae white, the distal tarsal 

 joint black. Eyes dark garnet. Face reticulated. Cephalic knees and 

 the caudo-lateral aspect of the cephalic tibiae honey-yellow. Lateral 

 ocelli their own width from the eye margins. Wings wholly hyaline, 

 the venation pallid yellow. Eyes coarse, the face concave. Antennae 

 inserted slightly ventrad of the middle of the face, distinctly dorsad of 

 an imaginary line drawn between the ventral ends of the eyes, the 

 scape long, slender, reaching up as far as the cephalic ocellus. Ocelli 

 in a mere curved line, nearly in the cephalic aspect. Body short, 

 robust, somewhat humped. The tibial spurs single, the tarsal claws 

 present but concealed from above. 



Fore wings transparent, clear, so clear that they are barely visible 

 in balsam mounts, the yellowish venation of the fore wings, however, 

 distinct, exactly as figured by Foerster (1851) for the type species but 

 less regular in outline ; the arch formed by the venation is much 

 broader, its true apex pointed more disto-cephalad and there acute, 

 with a seta at its extremity ; the stigmal vein is long, slender, narrow- 

 ing distad until the ovate knob is reached and the latter is not turned 

 back upon the neck of the vein but is a direct continuation and termi- 

 nation and besides bears a distinct uncus like a tooth ; the knob of the 

 stigmal vein is moderately large. The venation of the fore wing bears 

 about six distinct setae widely separated, unequal in length and from 

 distinct setigerous spots ; these are borne by the marginal vein and the
