 f ureal; recurrent vein entering first cubital cell near apical angle; 

 first abscissa of radius shorter than second, sometimes subequal; 

 radial cell short, ending much before apex of wing; last abscissa of 

 radius shorter than last abscissa of cubitus; nervellus nearly or quite 

 as long as lower abscissa of basella, which is distinctly shorter than 

 the upper abscissa; posterior coxae small, about as long as thfeir tro- 

 chanters, polished; posterior tarsi about as long as their tibiae; the 

 inner spur of hind tibiae about one-fourth the length of the metatarsus; 

 abdomen slender; first tergite very finely striate, with two distinct 

 fossae on the petiole above; remainder of abdomen smooth and 

 polished; ovipositor sheaths slender, fully three-fourths as long as 

 the abdomen. Black, face, clypeus, mandibles except tips, ferrugino-

 temples and cheeks dark ferruginous; a spot on the front extending 

 to and including the ocelli, black; occiput black; thorax alm.ost en

Type. — The types of humilis and agilis are in the Philadelphia 

 Academy of Sciences; that of rohustus is in the Museum of Public In- 

 struction, in Quebec; and that of orchesiae is in the United States 

 National Museum. . 



This species is very similar to terebratus and hicoriae, but can be 

 readily separated by the characters given in the key. The length of 

 the ovipositor sheaths will at once distinguish the females; while the 

 more or less roughened and opaque outer faces of the posterior coxae, 

 the length of the malar space, and the relative length of the first and
