Sculpture of thorax coarse P. striatus, sp. nov. 



Marginal vein short, only twice as long as the stigmal. 



P. aciculatus, sp. nov. 

 Marginal vein long, much more than twice as long as the stigmal. 



P. typicus, sp. nov. 



Palaeotorymus typicus, sp. nov. (Fig. 11.) 



Female. Length 3-5.5 mm. Color black, the abdomen fuscous. Probably 

 in life the color was metallic green with a yellowish brown abdomen. Wings 

 hyaline, the veins fuscous. Antennae dark colored, the joints toward the 

 middle of the flagellum a little longer than wide, becoming transverse nearer 

 the apex; they are thickest at about the sixth flagellar joint. Head behind 

 rather finely vertically striate or 

 aciculate; thoracic dorsum also 

 finely transversely striate, the 

 striations extending down over 

 the greater part of the pleurae. 

 Metathorax and metapleurae 

 smooth. Legs rather slender; 

 the tibiae and tarsi light colored, 

 except the base of the hind 

 tibiae. Hind coxae outwardly 

 transversely striate. Abdomen 

 about as long as the head and 

 thorax together, flat below and 



convex above, its surface smooth and polished. Ovipositor a little longer 

 than the abdomen. Marginal vein long, stigmal knobbed, with a distinct 

 pedicel, oblique; postmarginal very long, extending well toward the apex of 

 the wing, or at least indicated by a dark streak resembling a vein that is 

 very distinct. 



Type.— No. 2072 M. C. Z., Florissant, Col. (No. 610, S. H. Scudder 

 Coll.). Described from fourteen specimens, all in the Collection of 

 the M. C. Z., Nos. 2072-2082, 2195-2198, S. H. Scudder collection, 

 Nos. 610, 997, 2145, 4873, 4511, 4891, 5511, 6164, 6250, reverse of 

 6164, 7395, 8358, 8917, 10,032, 10,884, 13,354). 



The long postmarginal vein of this species is remarkable and is 

 shared also by the following species. There seems to be no doubt, 

 however, that they are close relatives of recent Toryminae in spite of 

 the peculiar development of this vein, and the long stigmal vein which 

 resembles that of the Idarninae.
