ART. 14 ICHNEUMON-FLIES OF GENUS POLYCYRTUS CUSHMAN 13 



subalar tubercle carinate; propodeum medially impressed from base 

 to apophyses with a rounded elevation on each side at base, carina 

 high and strongly curved medially, spiracles elongate, apophyses 

 moderately long, straight, compressed, about midway between carina 

 and apex; hind femur nearly twice as thick in middle as at apex, 

 inner calcarium nearly half as long as basitarsus; areolet rather 

 broad with recurrent shortly antefurcal, nervulus nearly intersti- 

 tial, postnervulus broken a little above middle, nervellus broken 

 above lower third. Abdomen minutely alutaceous; second tergite 

 a little more than three times as long as broad at base and nearly 

 as long as first; sheath about as long as hind tibia. 



Head black and white; thorax and abdomen entirely and legs 

 largely ferruginous; frontal and superior orbits, face, except medi- 

 ally, clypeus, mandibles, maxillary palpi, and annulus embracing 

 flagellar joints 5-10 white, labial palpi reddish fuscous; hind femur 

 piceous, darker above toward apex, tibia yellow, tarsus whitish; 

 wings yellowish hyaline, veins black, stigma somewhat paler. 



Type-locality. — Porto Bello, Panama. 



Type.— C^t. No. 42176, U.S.N.M.

8. POLYCYRTUS (POLYCYRTUS) INORNATUS, new species 



Female. — Length 11 mm. 



Differs from above description of ornatifrons as follows: Ver- 

 tex weakly concave; frontal horn stout conical; mouth hardly as 

 broad as narrowest width of face; temples from above more than 

 a third as long as short diameter of eye; basal joint of flagellum 

 fully eight times as long as thick. Anterior lateral margin of 

 pronotum not at all prominent, carina strong, epomia short but 

 distinct; mesopleurum impunctate, metapleurum weakly punctate; 

 propodeum not at all impressed and without basal elevations, carina 

 nearly straight medially, spiracles rather broadly oval, apophyses 

 stouter, subcorneal, not compressed; inner hind calcarium about 

 two-fifths as long as basitarsus, areolet small, recurrent strongly 

 antefurcal, postnervulus broken at middle. Second tergite barely 

 three times as long as broad at base and considerably shorter than 

 first ; sheath only about two-thirds as long as hind tibia. 



Head including mandibles entirely black; palpi stramineous, the 

 labial palpi darker; annulus beginning on fourth joint of flagellum; 

 hind femur ferruginous. 



Type-locality. — Rio Trinidad, Panama.
