sp. 



A deeply colored, stout species, the thorax much more strongly 

 sculptured than in the two preceding ones. 



Palaeotorymus aciculatus, sp. nov. (Fig. 12.) 



Female. Length 4 mm. Probably entirely metallic green, although there 

 are traces of ferruginous or brown on the abdomen. Thorax finely sculptured. 

 Head behind vertically aciculate on the sides and transversely so on the occi- 

 put. Pro- and mesonotum very 

 finely transversely aciculated. Pleu- 

 rae also coarsely aciculated, but not 

 regularly so except in patches. Base 

 of metathorax on the sides longitu- 

 dinally aciculated, the remainder of 

 the metathorax irregularly coarsely 

 sculptured. Ovipositor extruded; 

 preserved for only a short distance. 



Wings hyaline, the veins brown. Marginal vein short, not more than one- 

 half the length of the submarginal, the stigmal more than half as long as the 

 marginal, and but indistinctly knobbed. Postmarginal long as usual in the 

 genus. 



Type.— No. 2085 M. C. Z., Florissant, Col. (No. 2065, S. H. 

 Scudder Coll.). 



This species resembles P. ti/picus, but differs by its much shorter 

 marginal vein as well as in thoracic sculpture. Unfortunately the tip 

 of the ovipositor has been scraped away in cleaning the specimen. 



Ormyrodes petrefactus, sp. nov. (Fig. 13.) 



Female. Length more than 11 mm. Black, slender, tapering, the abdomen 

 two and one-half times as long as the head and thorax together. Head large,
