AMERICAN HYMENOPTERA. 85 



Selamlria albicollis, n. sp. (Sec. 1, Tr. 2, Div. B.) 



£ . — Length 0.30 ; br. wings 0.60 inch. — Color black, shining : a spot in the 

 middle of labrum, tegulse, edge of collar, a round dot in the. middle of the an- 

 terior angle, white ; the four hinder legs black above and brownish before; 

 anterior legs whitish-browu, their coxae and femora above, black ; inner claw- 

 tooth slender, not prominent; wings hyaline, the costal and basal nervures 

 white ;*first submarginal cell long oval, basal corners rounded ; the outer under 

 wing cells all open, their single inner cell subtriangular, their lanceolate cell 

 retracted. 



Texas. (Belfrage.) One specimen. 



Selandria q. alba, Norton. 



%. — (See. 4, Tribe 4). — About seventeen male specimens of this species ex- 

 amined. All have the under wings without middle cell ; all the outer cells 

 closed, the bounding nervure closely following the margin of the wing, the 

 inner ends of marginal, submarginal and discoidal outer cells all forming 

 nearl} 7 a straight line; lanceolate cell reaching the margin of wing: the four 

 anterior legs, below the middle of femora, are yellow-white; the apical two- 

 thirds of hinder femora and the basal two-thirds of the tibiae the same color. 

 The % of my S. obsoletum appears to be identical with this. 



9 . — (Sec. 4, Tribe 3). — The under wing middle cells of this seems to be quite 

 variable ; sometimes there are two inner cells on the wings, sometimes one and 

 at times none. 



This may easily be distinguished from all other species of this Sec- 

 tion (4) by the form of the lanceolate cell, which does not coincide at 

 tip with the cross-nervure above, as in figure 1 (ibid. p. 219), but ex- 

 tends a little beyond it, while in all others, the lanceolate cells does 

 not reach it, being shorter. 



Selamlria flavipes. Norton. (Sec. 5.) 



9 var — Length 0.25 ; br. wings 0.60 inch. — Differs in having all 

 the tarsi black, and the wings more clouded. The first submarginal 

 is incomplete as in many of our specimens. 



Cordova, Mexico. (Prof. Sumichrast.) One specimen. 



Selamlria coecinata, n. sp. (Sec. 5.) 



J. — Length 0.25 ; br. wings 0.60 inch. — Body stout; antennae long, stout, 

 joints diminishing equally in length and size; lower ocellus in an oval well de- 

 fined basin, channels at sides of ocelli curved, each rising in a pit back of each 

 upper ocellus, and eding in a little deep round pit back of each antenna, but 

 separated from pits of antennse; the bottom of these pits flat, with a central 

 prominence; nasus broadly truncate at margin; surface of head dull, rather 

 coriaceous, of body shining, not polished, nor punctured; inner claw tooth 

 stout, nearly as large as outer. Head black; basal joint of antennse, nasus, la- 

 brum and palpi, white; thorax and abdomen bright coccineous, with a round 

 spot on each side of scutel, sutures of metathorox, a double spot on pectus, and 

 ovipositor sheath, black; under a lens the red color on the thorax is seen to 

 color the prominences and fill the sutures, while the spaces between are waxen ; 

 the black spots are well defined; legs white, the intermediate tarsi and hinder 

 tibiae and tarsi blackish; wings slightly clouded, nervures black; all the an- 

 gles of first submarginal cell rounded ; a dark cloud around the lower shoulder
