Palaeotorymus laevis, sp. nov. 



Female. Length 4-5 mm. Body shining and rather stout, with the abdo- 

 men probably as dark in color as the head and thorax. Surface of head almost 

 smooth. Antennae stout, the flagellum of almost even thickness, slightly 

 stouter near the center where the joints are distinctly wider than long. Thorax 

 smooth except for a sparse coarse rugoso-punctate sculpture on the prothorax, 

 anterior part of mesonotum and the anterior part of the pleurae. The thoracic 

 sutures are deep and slightly crenulate. Abdomen stout, probably consider- 

 ably compressed, its surface smooth. Ovipositor not entirely preserved, but 

 more than half as long as the abdomen. Posterior coxae weakly and irregu- 

 larly punctate-striate above ; legs slender. Wings w T ith a rather short marginal 

 vein, the stigmal well developed and knobbed, one-third the length of the 

 marginal. Postmarginal vein at least one and one-half times as long as the 

 stigmal and probably longer, but its tip is obscured. 



Described from one specimen. 



Type.— No. 2083, M. C. Z, Florissant, Col. (No. 9655, S. H. 

 Scudder Coll.). 



This is quite similar to the preceding, but the thorax is smooth 

 except for some rough sculpture anteriorly. A second specimen, 

 later sent by Professor Cockerell collected at Station 17B appears to 

 belong to the same species. 



Palaeotorymus striatus, sp. nov. 



Female. Length 5 mm. Dark colored, probably metallic green, including 

 the entire legs. Head poorly preserved, its surface finely aciculate or sha- 

 greened; median joints of antennal flagellum distinctly wider than long. 

 Entire thorax coarsely sculptured ; prothorax transversely striate ; mesonotum 

 irregularly transversely punctato-striate, the striae curving posteriorly as 

 they extend down on to the upper part of the pleurae. Mesopleura deeply 

 confluently punctate. Metathorax obscured, but apparently smooth with a 

 few coarse reticulations. Abdomen short, ovate in lateral view. Ovipositor 

 exposed only at the base, but I think it can be seen as a trace through the stone 

 for a distance greater than the length of the abdomen. Legs very stout, but 

 this may be due in part to pressure. Wings strong, the veins piceous. Stigmal 

 vein long, knobbed; two-fifths as long as the marginal; postmarginal stout 

 for a distance twice the length of the stigmal, then continued less distinctly 

 nearly to the wing tip. 



One very well preserved specimen. 



Type.— No. 2084, M. C. Z., Florissant, Col. (No. 10,315, S. H. 

 Scudder Coll.).
