ICHNEUMON-FLIES OF GENUS CARDIOCHILES — MAO 231 



Eye hairy or bare; scape and pedicel shining and with longer 

 pubescence than the flagellum ; antennae miiltiarticulate, the number 

 of segments not constant within species; scape rather stout, pedicel 

 short and globular; face 1.0 to 3.0 times as wide as long and usually 

 with a medial tubercle or short ridge above, or with a median longitudi- 

 nal carina; occiput more or less concave, immargined; notaulices al- 

 ways distinctly impressed, usually f oveolate, rarely smooth ; prepectus 

 immargined; mesopleuron with upper, lower, and posterior grooves 

 (pi. 4, fig. 3), the first two foveolate or smooth, the posterior groove 

 always foveolate; propodeum usually rugose and usually areolated; 

 third abscissa of radius arched or subangulate basally ; interanal vein 

 represented by a short stump continued as a pigmented line, or by a 

 pigmented line only, rarely absent; hind tibia sometimes simple but 

 often somewhat compressed and broadened more or less toward apex, 

 which may be expanded into a flaring process; hind basitarsus more 

 or less flattened ; tibial spurs long, hind tarsal claws usually pectinate 

 or toothed ; first abdominal suture curving slightly to the margin or 

 extending obliquely forward to the margin (pi. 4, figs. 10, 11) ; second 

 tergite usually shorter than, rarely as long as, the third; ovipositor 

 sheath short or long but never longer than the abdomen.

 rowly, outer broadly, and ventral incompletely, ferruginous, eye gray- 

 ish black; clypeus pale ferruginous, its apical margin black; wings 

 fuliginous; legs ferruginous, except coxae, trochanters basally, and 

 femora basally, black and hind tarsi dusky; abdomen ferruginous; 

 ovipostor sheath black. Antenna around 32-segmented ; eye bare; 

 ocelli elevated ; vertex smooth, polished ; f rons polished with a slight 

 depression below anterior ocellus followed by a weak, median, longi- 

 tudinal elevation ; face about 2.50 times as wide as long, punctate, con- 

 vex, with a short median ridge above and below this slightly elevated ; 

 clypeus punctate, its median basal portion elevated, its apical margin 

 slightly flaring, and not notched; temple bulging, wider than eye in 

 dorsal view ; malar furrow about 0.G7 as long as the basal width of the 

 mandible; galea tapering, slightly shorter than the long axis of the

 median lobe of mesoscutum with a shallow longitudinal depression 

 each side of the median line ; notaulices moderately foveolate ; upper 

 groove of mesopleuron foveolate ; lower groove weakly foveolate ; pos-
