AKT. 14 ICHNEUMOlSr-FLIES OF GENUS POLYCYRTUS CUSHMAN 9 



tures in humeral angle of pronotum and on mesopleurum ; pronotum 

 with a high carina along its lower anterior margin but without 

 epomiae, its upper margin impressed opposite notauli, furrow along 

 its posterior margin distinctly foveolate below, obsoletely above; 

 mesoscutal lobes high, not at all flattened on top; scutellum very 

 high; mesopleural and prepectal furrows foveolate; propodeum pol- 

 ished, without sculpture, basal carina very strong, straight in middle, 

 basal area slightly concave medially, apophyses short, compressed, 

 situated about midway between carina and apex; areolet of normal 

 form with recurrent slightly antefurcal, nervulus interstitial or 

 nearly, subdiscoideus slightly above middle of postnervulus, ner- 

 vellus broken distinctly below middle. Abdomen slender, post- 

 petiole less than twice as wide as petiole; second tergite fully three 

 times as long as broad at base and very slightly shorter than first 

 tergite; abdomen toward apex with sparse long whitish hairs; ovi- 

 positor sheath distinctly less than twice as long as first segment. 



Thorax, legs, and first segment of abdomen except apex ferrugi- 

 nous to testaceous; head, antennae, and abdomen black; clypeus, 

 mandibles, palpi, and antennal annulus beginning at apex of fourth 

 flagellar joint white (the antennae are missing beyond this point) ; 

 hypostomal carinae stramineous; legs beyond femora yellowish, the 

 posterior tarsi whitish, apex dark; wings yellowish hyaline, venation 

 dark, radices and tegulae stramineous; gastrocoeli pale reddish; 

 tergites beyond first narrowly reddish at apex and more broadly 

 whitish laterally, venter whitish. 



Male. — Essentially like female. Antennal annulus beginning on 

 apex of sixth flagellar joint; apophyses shorter and nearer to apex 

 than to carina ; propodeum obsoletely roughened behind and between 

 the apophyses; abdomen narrower. One specimen has a trace of a 

 median groove between apophyses and carina. 



3. POLYCYRTUS (CRYPTANURmiMORPHA) ALBINICLAVUS, new species 



Figure 1 



Female. — Length 12 mm. 



Very closely related to capitator (Fabricius) Brulle ajid perhaps 

 not specifically distinct. The following differences, however, are 

 noted: the eyes appear somewhat smaller in front view; the small 

 tubercle above the frontal horn is replaced by two transverse ridges 

 traversing a shallow impression that is defined laterally by obsolete 

 dorsally diverging ridges ; frontal horn white. Antennae broken. 



Type-locality. — Gourdonville, French Guiana. 



Type. — Paris Museum. 



One specimen taken by R. Benoist in 1914.
