 cluding the scutellum shining, remotely punctured, wings hyaline, 

 nervures piceous, 2nd recurrent received in the 2nd submarginal

 posteriorly by a shining curved somewhat raised line, abdomen

 being more finely punctured. The antenna? are testaceous beneath 

 and at the apex, and the joints of the flagellum are very .'^hort and 

 transverse, vertex of the head and mesonotum rather closely but 

 irregularly punctured, in this respect very different from viUyaris, 

 propodeum like that of the ^, puncturation of the abdomen less 

 strong than in the ^ but well marked, that of the basal segment 

 stronger and more remote than of the others, impressions very wide 

 and pale piceous, legs more or less piceous varying very much in 

 depth of colour.

 in the shallower abdominal impressions and the more 

 polished mesonotum wliich is scarcely jaunctured.
