joints. Wing veins brown, with darker spot at juncture of submargi- 

 iial and stigmal. 



Described from one female specimen taken in Placer County, Cal., 

 by A. Koebele, in August. Type in the U. S. National Museum. 



BOTHRIOTHORAX PLANIFORMIS, new species. 



Female. — Length, l.Smm. ; expanse, 3.9 mm. ; greatest width of fore- 

 wing, 0,8 mm, Axillic nearly touching, scutellum not emarginate, 

 eyes plainly hairy; notum of thorax flat, mesoscutum and scutellum in 

 same i)laiie. Head punctured as with j^receding species on front and 

 vertex; facial depression very distinct, occupying nearly all of lower 

 half of face, depression irregularly shagreened; face between depres- 

 sion and genal sulcus, rugose; cheek behind sulcus faintly longitudi- 

 nally sbagreened. Punctures of mesoscutum rather sma'l and less ])ro- 

 uounced than those of the head, but dense and accomi)anied by faint 

 sbagreening; on mesoscutellum punctures become nuich sparser, and 

 the shagreening, which takes a longitudinal direction, much more 

 marked. Axilhe with many small ])unctures; teguhe faintly .sha- 

 greened over entire surface; mesoi>leura distinctly shagreened, espe- 

 cially on anal lialf. Abdomen smooth at sides, faintly shagreened above 

 aiul below, ovipositor distinctly exserted. Both scape and flagellum 

 of antenme rather longer than in preceding species; first funicle joint 

 longer than second and rather shorter than pedicel; third and fourth 

 ecjual to second; fifth, and sixth equal to first; club as with preceding 

 si)e('ies. General color black, faintly metallic, mesoscutellum with faint 

 coppery luster, facial depression with brilliant purple luster; tegulie 

 black, somewhat metallic, middle tibiiB becoming lighter toward tip; 

 tarsi as usual yellowish, with black apical joints. Wing veins brown, 

 stigmal and short projection of submarginal darker than submarginal. 



Described from one female specimen collected in Placer County, Cal., 

 by A. Koebele, in August. This species resembles Phccnpdiscus in 

 punctation of mesoscutellum, but in venation and other respects 

 belougs to Bothriothorax. Type in the U. S. National Museum.

 Synopsis Hynienoptera North America, pt. ii, p. 240. 



This si)ecies, Mr. Ashmead informs me, is not a Bothriotliorax. He 

 has kindly allowed me to see the type, and it seems to form a new 

 genus near Comys, but lacks the scutellar tuft. 



P E N T E L I C U S , new genus. 



Female. — In habitus this form is intermediate between Bothriothorax 

 and Chalcaspis, but has the shagreened mesouotum of PJuvnodiscus, 

 tlie round ])unctures of the mesouotum, however, being rather close 

 instead of sparse. It is not so short and broad as Chalcaspis. The
