 nervure nearly effaced. Legs shorter than those of sp. 3, testaceous, 

 including the coxa3. Abdomen compressed from the base of the 

 3rd segment, carinated above throughout its length ; 1st segment 

 one half longer than broad, with salient tubercles situated near the 

 base ; 3rd and following segments black, as well as the short valves

Abdomen dark-brown, the 2nd and 3rd segments with a rufous 

 tinge. $ head and thorax black ; prothorax sometimes rufo- 

 testaceous above. Head subglobular, not wider than the thorax ; 

 clypeus rufotestaceous ; palpi paler. Antennae very slender, filiform, 

 as long as the body, with 19 joints, of which the two basal are rufes- 

 cent, the 3rd testaceoiis, and all the rest black ; 3rd joint very long. 

 Mesothoracic furrows distinct ; prothorax wrinkled transversely, 

 sometimes black beneath and sometimes rufous ; metathorax smooth, 

 without a medial carina. Wings hyaline ; squamulse, radicles, and 

 nervures pale brownish testaceous ; stigma very pale, yellowish ; 1st 

 disco'idal areolet not entirely separated from the 1st cubital ; radial 

 nervure curved without an angle, its external portion (the 3rd 

 abscissa) traced almost invisibly to the tip of the wing, as also is the 

 cubital nervure. Legs obscurely testaceous. Abdomen longer than 

 the head and thorax, lanceolate, brown, black at the extremity, some-

 of the $ , 22-jointed, black with the two basal joints brownish ; 3rd 



* The valves of the terebra of Hymenoptera being almost always 

 black, it seems superfluous to mention their colour ; but as some of 

 the present group have testaceous valves, the distinction must be 

 noticed.
