by the merest trace of the suture distinguishes it from all of the 

 genera placed in the Stilpnini by Foerster and by Schmiedeknecht. 

 In the keys of both writers it runs best to Xestophya Foerster be- 

 cause of the lack of the second intercubitus. In Myersia, however, 

 the aerolet may almost be said to be entirely lacking, the very short 

 intercubitus and nearly straight apical abscissa of the cubitus barely 

 defining it. 



From Foerster's description of Xestophya^ it differs principally 

 as follows: Head transverse, rather strongly narrowed behind the 

 eyes; clypeus more or less distinctly separated, especially laterally, 

 where it is flanked by very deep, round fossae; malar space with a 

 band of fine sculpture separating the face from the cheeks ; postocel- 

 lar and ocell-ocular lines subequal; antennae in female 18-jointed; 

 notauli deep anteriorly, fading out posteriorly; prepectal carina 

 (" die vorne aufsteigende Brustleiste " of Foerster) oblique and 

 joining the promesothoracic suture somewhat below the middle; the 

 middle lateral and middle pleural areas of the propodeum separated 

 by a strong carina ; first tergite longer than the combined hind 

 coxa and trochanter, the postpetiole much wider at apex than thd 

 petiole; second and third tergites completelj^ fused, the only trace 

 of the suture being a short groove at each side, these two tergites 

 occupying nearly the entire dorsal and lateral surfaces and overlap- 

 ping below, the third, as seen from above, not much broader than 

 long; ovipositor distinctly exserted; hind tibiae not swollen, the 

 longer spur reaching nearly to the middle of the metatarsus, last 

 tarsal joint as long as third ; stigma very narrow, the radius originat- 

 ing in the middle, second abscissa forming with the first a right angle. 



MYERSIA PALLIDA, new species. 



Immediately distinguishable from the genotype and only described 

 species laminata Viereck by its pale ferruginous color. 



Female. — Length, 4 mm. ; antennae, 3 mm. 



Head in front view nearly as long as wide, subtriangular, face 

 finely, irregularly, transversely striate, subpolished and lightly sha- 

 greened at sides, the latter sculpture extending to the frons and ver- 

 tex, temples convexly sloping, polished; clypeus sharply separated 

 except narrowly at middle, opaque, coarsely, sparsely punctate, as 

 are also the mandibles; face, clypeus, and mandibles with long, 

 coarse, erect hairs, longest on the clypeus ; malar space fully a half 

 longer than basal width of mandible ; mesoscutum and sctellum finely 

 shagreened, with indistinct, sparse punctures; pronotum shagreened, 

 striately so below; mesopleura longitudinally striate, the sternauli 

 broadly impressed ; metapleura finely opaque above, strongly, irregu-
