Female. — Length 1^ lin. Rufo-testaceous : sprinkled with a 

 few erect scattered hairs ; the head finely longitudinally rugose- 

 striate; the stemmata very prominent, and of a glassy brightness; 

 the scape and base of the flagellum pale flavo-testaceous, the 

 legs are of the same colour; antennise apparently 12-jointed. 

 Thorax rounded anteriorly, the mesothorax finely longitudinally 

 striated ; the insertion of the wings, the scutellum and post-scu- 

 tellum, rufo-fuscous, the scutellum smooth and shining in the 

 middle; the spines on the metathorax short and acute; the wings 

 hyaline, the nervures scarcely discernible ; the nodes nearly 

 smooth, shining, the first slightly roughened. Abdomen ovate, 

 smooth and shining, the first segment pale at the base, beyond 

 which it is rufo-fuscous, sometimes entirely fuscous, or with the 

 basal margins pale. 



Worker. — Closely resembles the female, differs in wanting the 

 ocelli, and in having the sides of the thorax compressed, and 

 slightly strangulated at the apex of the mesothorax, which is 

 much more finely sculptured than in the female, and granulated: 

 the teeth -on the metathorax minute, acute at their apex. 

 Abdomen ovate, very smooth and shining, the first segment
