AMERICAN HYMENOPTERA. Ill 



G. Birkmann at Fedor, Texas, May 24, 1899. This species was 

 originally described by Cresson (Tran. Am. Ent. Soc. iv, p. 

 224, 1872) and placed in the genus Nysson with doubt. Ash- 

 mead (Ent. News, Oct., 1898, p. 2S9) placed it in the genus 

 Niteliopsis where it belongs. The type is in U. S. Nat. Mus. 

 It is a female. The following notes made from it by Mr. J. 

 C. Crawford will be useful: — ■ 



" In answer to your queries, let me say first that the head 

 and prothorax of the type of N. inerme are eaten off, so thatT 

 cannot answer in regards to those characters. The second 

 submarginal receives both recurrent nervures, the first one at 

 the base, interstitial, not squarely but slightly basal. The 

 marginal is not distinctly appendiculate, but has a smoky 

 darkening both on the anterior margin and at the lower 

 apical angle. The submedian cell is slightly longer than the 

 median, the nervure joining very slightly beyond." 



Niteliopsis licidis n. sp. 



Male. — Length 4 mm. Clypeus with the lateral margins oblique, 

 in the middle with a broad obtusely rounded tooth; middle carina not 

 very sharp. Head finely granular; vertex shining with separated 

 punctures; frontal carinae strongest where they unite, which is a little 

 more than the length of the scape above the level of the antennae. 

 Ocelli in a little less than an equilateral triangle; the furrow from the 

 lower ocellus extending both above and below it. Antennae stout, 

 thickening towards the apex; second and third joints subequal; apical 

 joints long, tapering to an acute apex, third joint equal with the 

 fourth. Prothorax rounded on the anterior margin, with a faint 

 longitudinal carina in the middle. Dorsulum with distinct, separate 

 punctures; scutellum similarly sculptured, very slightly impressed. 

 Metanotum with a triangular shaped area which is longitudinally 

 striated; metapleuras striato-granular; posterior face with a middle 

 fovea, transversely striated. Radial cell with an appendiculation, 

 but a faint one, however; first recurrent nervure joining the cubitus 

 quite free from the first tran. cu.; second recurrent nervure joining 

 the cubitus in about the middle of the second cubital; tran med. and 

 basal interstitial. Abdomen punctured appearing granular; a con- 

 striction between the first and second segments; eighth ventral plate 

 broadly, deeply, circularly emarginate; lobes narrow acute. Color 

 black; mandibles (apices piceous), two spots on the pronotum which 

 almost unite, tubercles, tegular, postscutellum, apices of the four 

 anterior femora and beneath almost to the base, all the tibiae except
