Myersia laminata Viereck. 



What I am convinced is the male of this species is represented 

 in the National Collection by ten specimens, one from Jackson's 

 Island, Md. (P. R. Myers); one from Rosslyn, Va. (H. H. 

 Smith); two from Dixie Landing, Va. (Ashmead); five from 

 Langdale, Ala. (H. H. Smith); and one from Long Island, N. Y. 

 The most striking difference between the male and female is in 

 the possession by the male of a depressed and normally segmented 

 abdomen, the second and third tergites being not at all fused. 

 Other points of difference are in the relatively shorter (facial 

 view) head; shorter malar space; more distinctly carinate 

 anterior margin of cheek; nearly paralleled eyes; basally 

 thickened and apically tapering antennae; less deeply concave 

 propodeum with less prominent angles; and narrower and more 

 roughly sculptured postpetiole. The color of the two sexes is 

 the same except that the male has the antennae beyond the 

 second joint of the flagellum and usually the posterior tibiae and 

 tarsi fuscous. In some of the specimens, especially those from 

 the south, the base of the abdomen is quite red. 



Myersia johnsoni, new species. 



Female. Length 4 mm. 



Differs from laminata Viereck in having the antennae somewhat more slender, 

 the subapical joints being fully as long as thick; the abdomen less stout, the 

 postpetiole at apex being but little more than twice as wide as the petiole and the 

 rest of the abdomen nearly twice as long as wide; all coxae and the hind femora 

 and tibiae fuscous. 



The apical abscissa of radius in this and in laminata is basally slightly curved 

 but otherwise straight, not sinuate as in pallida. 



Type-locality. South West Harbor, Mt. Desert Island, 

 Maine. 



Type Cat. No. 24143, U. S. N. M. 

 A single specimen taken by C. W. Johnson. 

 It is entirely possible that the differences noted between this 

 and laminata are within the range of specific variation. 



Myersia grandis, new species. 



Female. Length 6 mm. 



Head in dorsal view transversely oblong, deeply concave behind, temples 

 broad, flat, nearly straight, the occiput nearly as broad as eyes; in front view 

 almost as long as broad, cheeks weakly convex, malar space more than twice as 

 long as basal width of mandible; clypeus hardly twice as wide as long, broadly 

 truncate at apex and with a narrow reflexed margin, weakly sculptured at base; 

 face granular medially, subpolished laterally; eyes strongly divergent below; 

 frons with deep, subpolished scrobes, separated by a low ridge; vertex granulated; 

 cheeks and temples highly polished; antennae slightly more slender than in 

 laminata, the subapical joints longer than thick, scape about two-thirds as thick 

 as long. Thorax granulate dorsally, largely longitudinally striate laterally;
