358 ENTOMOLOGICAL NEWS [Oct., '09 



tusely rounded and somewhat produced posteriorly. Mesopleurae stri- 

 ato-granular. Metathorax emarginate posteriorly and the metapleu- 

 rae are narrowed beneath ; the posterior face wth a faint channel 

 down the middle, the surface striato-punctate ; metapleurae shining; 

 metanotum rugose. Legs short and rather slender; the middle tibiae 

 with two apical spurs; the tarsal claws simple. Radial cell broadest 

 opposite the second transverse cubitus ; with a short appendiculation 

 at the apex. The second cubital cell narrowed above, about a third 

 as wide on the radius as the third cubital. The first recurrent received 

 by the second cubital cell about the length of the second transverse 

 cubitus from the second transverse cubitus; the second recurrent 

 received by the third cubital cell about the length of the second 

 transverse cubitus from the second transverse cubitus. The trans- 

 verse median, which is received a little before the basal nervure, is 

 not straight, but is strongly bent toward the apex of the wing. The 

 transverse median of the hind wings is straight, perpendicular, and 

 interstital with the transverse cubitus. Abdomen sessile, somewhat 

 the shape of members of the genus Oxybelus; shining, the first seg- 

 ment sparsely punctured, the second and following segments with 

 distinct, separate punctures, closer than those on the first segment ; 

 there is no pygidial area. Black ; two transverse spots on the top of 

 the clypeus, a round spot at the summit of each eye, pronotum, margins 

 of the tegulae, spot below the tegulae, spot before the scutellum, 

 spot on the scutellum, an even band on the posterior margin and sides 

 of the first segment, a band on segments 2, 3, and 4, widened greatly 

 at the sides and emarginate between the sides and the middle, cream- 

 colored. Middle of the tegulae brown ; flagellum slightly reddish be- 

 neath. Leg below the trochanters light ferruginous, the apex of the 

 anterior femora beneath, and the four posterior tibiae exteriorly 

 cream-colored. Wings clear hyaline ; venation brown to black. Head 

 and thorax with a little silvery pile. 



Type locality: Las Cruces, N. M. One specimen collected 

 August 31, at flowers of Solidago canadensis by C. H. T. 

 Townsend. I am much indebted to Prof. T. D. A. Cockerell 

 for the specimen, and for offering- some helpful suggestions. 



This is a most remarkable little wasp. I am by no means 

 sure that it belongs to the genus Psiloglossa Saunders ( = 

 Stenoglossa Sauss.), but place it there for the present. The 

 simple tarsal claws would seem to put it in the subfamily Ves- 

 pinae. It is not anything like most of these however, while it 

 does resemble some species of Odyncrns in general habitus. 

 The genus Psiloglossa has not before been reported from the 

 Western Hemisphere.
