10 PEOCEEDINGS OF THE NATIONAL MUSEUM vol.78 



Would perhaps be better treated as a variety of capitator (Fabri- 

 cius) Brulle, but limited material renders its treatment as a distinct 

 species advisable for the present. 



4. POLYCYRTUS (CRYPTANURIDIMORPHA) INCA, new species 



ICryptus capitator Fabricius, Syst. Piez., 1804, p. s2, female. 



Female. — 12 mm. 



Like the last species above, perhaps no more than a variety of 

 capitator (Fabricius) Brulle, but differs from that species as follows : 

 furrow between hypostomal carina and cheek deep and carinately 

 denned ; lateral lobes of mesoscutum flattened ; apophyses longer and 

 distinctly nearer to apex of propodeum than to carina; antennal 

 annulus beginning near base of fourth flagellar joint; frontal horn 

 white ; hind femur largely blackish. 



Type-locality. — Caja, Peru. 



Type.—Q2X. No. 42174, U.S.N.M. 



One specimen taken by Dr. P. Weiss. 



As suggested above, this may be the true capitator- (Fabricius). 



5. POLYCYRTUS (CRYPTANURIDIMORPHA) TUBULIFERA (Viereck). (New 



combination) 



Cryptopterigimorpha tuhuUfera Viereck, Proc. U. S. Nat. Mus., vol. 46, 1913, 

 p. 371, female. 



Known only from the unique female type. 



Very distinct in coloration from any other species of the sub- 

 genus, the head and anterior portion of the thorax being immaculate 

 black and the rest of the body and the legs pale reddish testaceous. 



Female. — Vertex and frons deeply concave, latter with rather dis- 

 tinct scrobes and a short thick horn without tubercle or ridges at 

 base; eyes very nearly parallel within and comprising very nearly 

 two-thirds of width of head at level of antennae ; face with a rather 

 deep longitudinal impression on each side of middle ; clypeus in profile 

 concavely inflexed at apex; malar space subequal to basal width of 

 mandible; hypostomal carinae contiguous to nearly opposite ventral 

 articulation of mandible ; the flanking grooves separated from cheeks 

 by carinate margins ; temples concave and very narrow. Pronotum 

 above, mesoscutum anteriorly, and mesopleurum and sternum 

 sparsely and rather coarsely punctate ; pronotum strongly carinate 

 along its anterior lateral margin and deeply impressed on dorsal mar- 

 gin opposite notauli; lobes of mesoscutum not especially elevated, 

 metapleurum irregularly rugose; propodeum with carina straight 

 and very high, basal area punctate, not or barely impressed medially, 

 apical slope medially more or less longitudinally roughened, apophy- 

 ses very long ; second recurrent and nervulus antef ureal ; postnervulus 

 broken at middle, nervellus broken at lower third; legs, especially
