224 E. T. CRESSON. 



narrow line on each side at apex of second and third segments and narrow 

 apical margin of all the segments except the last, pale yellow ; sometimes 

 the spots and lines are dull yellow, while the narrow well-defined margins are 

 bright golden. Length .30— .45 inch. 



£ . — Has the sides of the face and clypeus bright silvery ; the coxa?, tro- 

 chanters and femora except tips sometimes blackish; the fourth and some- 

 times the sixth abdominal segments above with a lateral apical pale yellow 

 spot; tip of apical segment with four teeth, the lateral ones very short. 

 Lenght .30 — Ao inch. 



Six specimens. (Belfrage ; Boll.) Closely allied to aurinotatus, 

 Say. 



Nysson? inerme, n. sp. 



9 .—Black, sides of face, clypeus and cheeks bright silvery, tip of clypeus 

 polished; mandibles slender, acute, whitish, tips black; head slightly broader 

 than thorax, transverse, a double prominence on middle of the front just 

 above antennae, which are inserted close to base of clypeus and are short and 

 robust; ocelli arranged in a triangle; thorax shining, feebly punctured ; a line 

 on prothorax above, slightly interrupted medially, tubercles, tegulae and band 

 on postscutellum, white; metathorax opaque, finely granulated, rounded, un- 

 armed, covered laterally with a silvery sericeous pile; wings hyaline, dusky 

 on apical margin; marginal cell long, sublaneeolate, blunt at tip, first submar- 

 ginal cell long, large, broader than in Nyseon., receiving the first recurrent 

 nervure at its extreme apex, second submarginal small, subtriangular, petiol- 

 ated, receiving the second recurrent nervure, which is very much bent out- 

 wardly, at about the middle, third submarginal obliquely subquadrate, as in 

 Sarpactus; legs short, slender, apical half of four anterior femora beneath, and 

 a line on all the tibiae behind, whitish ; tarsi brownish ; abdomen subsessile, 

 convex, shining, apex acuminate, second and third segments contracted at base, 

 first segment prominently convex above, the following segments covered with 

 a silvery sericeous pile, especially on the sides, only visible when viewed in 

 certain lights; ovipositor exserted ; second ventral segment not protuberant. 

 Length .23 inch. 



One specimen. (Coil. G. W. Belfrage.) Seems intermediate be-

 mesothorax with large punctures, sparse on the disk; upper posterior margin 

 of prothorax, tubercles, lateral margin of mesothorax, two spots on scutellum, 

 nearly confluent at base, postscutellum, dot on tegulae and a spot beneath,
