NO. 2261. NEW BEARED PARASITIC HYMENOPTERA—GAHAN. 117 



head as viewed from in front decidedly broader than its median 

 length instead of practically as long as broad; by having the pos- 

 terior lateral angle of the propodeum produced into a rather strong 

 tooth instead of very weakly produced ; by having the abdomen more 

 strongly sculptured, the rugosities forming more distinct longi- 

 tudinal ridges or irregular striations ; by having a longer ovipositor 

 and more prominent hypopygium, the hypopygium in all of the 19 

 female specimens at hand being thrust out from beneath and ex- 

 tending posteriorly beyond the apex of the carapace; the ovipositor 

 from basal hinge to apex of sheaths equal to about two-thirds the 

 length of the abdomen, its apex projecting from the hypopygium a 

 short distance. 



Female. — Length 2.8 mm. Black; mandibles at apex, two anterior 

 pairs of tibiae and tarsi entirely, their femora and the hind tibiae and 

 tarsi for the most part dark reddish testaceous. Wings hyaline, the 

 costal vein and stigma dark brown, the other venation brownish 

 testaceous. Antennae 16-jointed, the first flagellar joint only slightly 

 longer than the second, which is equal to the third ; clypeus somewhat 

 shining with moderately close rather weak punctures, its anterior 

 margin somewhat produced and slightly elevated; face rugose; frons 

 with rather strong striatiform rugae laterally which are curved 

 downward from the ocelli along the eye margin, the depressed area 

 above the antennae shining with suberased rugae and divided by 

 a weak median longitudinal raised line; vertex transversely rugose, 

 the rugae curving downward behind the eyes; mesonotum with 

 coarse pits or foveae on the posterior middle and the parapsidal fur- 

 roAvs strongly foveate, the remainder of mesoscutum more finely 

 sculptured, opaquely rugulose; scutellum shining with suberased 

 punctures; mesopleura coarsely pitted like the posterior middle of 

 mesoscutum; propodeum coarsely rugoso-punctate, with a rather 

 well defined median dorsal areola, the tooth at the posterior lateral 

 angles distinct but not long; nervulus postfurkal by nearly its own 

 length, first and second radial abscissae nearly equal in length and 

 forming a distinct angle at their junction; abdomen at its broadest 

 point narrower than the thorax at tegulae, strongly convex above and 

 more narrowed at apex than usual for the genus; the ventral con- 

 cavity extends to the apex of the abdomen ; ovipositor as described 

 above. 



Male. — Agrees with female except that the antennae are 20-jointed 

 in the allotype, the abdomen is more rounded at apex, not at all com- 

 pressed from the sides, the ventral concavity does not extend to the 

 apex, and at the apex of the abdomen is a deep, nearly circular in- 

 cision from the middle of which projects a short horn ; this aperture 

 in related species is usually very strongly transverse.
