TEXAN HYMENOPTKRA. 161 



remaining joints very short; metathorax truncate behind, posterior face con- 

 cave, lateral angles prominent ; tegulse pale ; wings hyaline, areolet rather large, 

 5-augular, the upper apical nervure hyaline,- legs subrobust, and including the 

 coxse entirely ferruginous ; abdomen rather broad, ovate, smooth and shining, 

 first segment black at base, broadly dilated at apex; ovipositor about three- 

 fourths the length of abdomen. Length .20 inch. 



Two specimens. (Belfrage.) This species seems to be intermedi- 

 ate between vulgaris, Cress., and /)MSi7/i<s, Cress., being less robust than 

 the former, and more robust than the latter; in coloration it resem- 

 bles both species. 



Phygadeuoii tiniidiis, n. sp. 



%. — Slender, shining; head, antennae and thorax black; palpi pale; most 

 of mandibles and scape beneath ferruginous; antennae long, slender; meta- 

 thorax rounded, with distinct elevated lines, forming a large central area, and 

 with small acute lateral tubercles; tegulse j^ale; wings hyaline, areolet small, 

 irregularly 5-angular; legs, including coxae, pale ferruginous, bases and tips of 

 posterior tibiae, their tarsi and tips of four anterior tarsi black; abdomen 

 slender, first segment long, narrow, black, longitudinally aciculated; second 

 Segment blackish ferruginous on disk and narrowly so at apex; third segment 

 entirely and most of fourth and tifth ferruginous; sides of the latter and the 

 apical segments black. Length .20 inch. 



One specimen. (Coll. G. W. Belfrage.) This may possibly be the 

 male of the preceding species. 



Heuiiteles conspiceius, n. sp. 



5". — Ferruginou.s; apex of antennae, and tips of mandibles blackish; scu- 

 tellum gibbous; pleura finely rugulose; metathorax unarmed, rugulose, with 

 tolerably well defined longitudinal elevated lines, apex truncate, sides with 

 sparse, short, pale jiubescence ; wings shorter than usual, hyaline, anterior pair 

 with three fuscous bands, viz.: a narrow one at base of first submarginal cell, 

 a very broad one extending fi-om base of stigma nearly to apex of marginal cell 

 and rounded beneath, the third one narrowly margining the apex; areolet 

 marked by a hyaline spot, second recurrent nervure nearly straight; posterior 

 wings hyaline, apex fuscous; legs long, slender, concolorous with body; abdo- 

 men petiolate, depressed, fuscous towards apex ; three basal segments finely 

 longitudinally aciculated, the fourth smooth and shining; apical segments 

 with pale pubescence; first segment broadly dilated at ajiex ; ovi^wsitor about 

 one-half the length of abdomen. Length .30 inch. 



One specimen. (Coll. Gr. W. lielfrage.) A very handsome and 

 conspicuous species ; the broad middle baud on anterior wing h;is a 

 rounded appearance.
