ABT.23 NEW AMERICAN ICHNEUMON-FLIES CUSHMAN 11 



Genus CAMPOPLEX Gravenhorst 



The new species described below runs in Schmiedeknecht's key ' 

 to couplet 30 where it agrees with all of the characters assigned to 

 Eulimneria Schmiedeknecht except that the head is not broad behind 

 the eyes. Beyond this point it runs to IdecMhis Foerster. Both 

 Eulimneria and IdecMhis I consider as synonyms of Campoplex 

 Gravenhorst. 



CAMPOPLEX DIGITATUS new species 



Female. — Length 6.5 mm.; antennae, 5 mm.; ovipositor, 0.8 mm. 



Head transverse with temples convexly sloping, in front view 

 slightly transversely oval; face slightly narrower than frons; eyes 

 shallowly emarginate opposite antennae; face and clypeus opaque, 

 finely, densely punctuate; malar space hardly half width of mandible; 

 ocell-ocular line, ocellar diameter, and postocellar line in the propor- 

 tion of 1:1.5:2; flagellum rather stout, tapering at apex. Thorax 

 stout ovoid, granularly opaque, speculum not at all polished; pro- 

 podeum dull, rugulosely roughened, areola and petiolar areas con- 

 fluent, broad, concave, costulae distinct; stigma about a fourth as 

 wide as long, areolet petiolate, recurrent near apex, external angle of 

 second discoidal cell acute, nervulus postfurcal, postnervulus broken 

 at about the middle, nervellus curved but not broken, reclivous; 

 longer hind calcarium a little more than two-thirds as long as basi- 

 tarsus; basitarsus as long as rest of tarsus, apical joint hardly longer 

 than fourth, claws pectinate. Abdomen very minutely granularly 

 opaque, more or less punctate toward base; first tergite stout, the 

 postpetiole broad and strongly convex, petiole laterally foveate at 

 base of postpetiole; second tergite one and two-thirds times as long 

 as broad at base, spiracles beyond middle, gastracoeli shallow but 

 distinct, removed from base; ovipositor sheath much shorter than 

 first tergite, ovipositor upcurved. 



Black with basal three tergites more or less reddish toward apex; 

 mandibles, palpi, tegulae and wing bases white; antennae black, 

 scape red beneath; wings hyaline, venation dark, stigma paler; front 

 legs stramineous except the pale testaceous femur; hind coxa, basal 

 joint of trochanter and femur testaceous, apical joint of trochanter 

 stramineous, tibia with apical third and a narrow subbasal annulus 

 black, the rest white, tarsi black with basitarsus broadly and other 

 joints very narrowly white at base; middle leg like front leg except 

 that the tibia and tarsus have the pattern of those of the hind leg 

 repeated in pale testaceous and white. 



Male. — Like female but ocelli larger, the ocell-ocular line, ocellar 

 diameter, and postocellar line ratio being 1:2:2; the abdomen nar- 

 rower and entirely black; and the legs with more white.
