nally rugose than the head ; mesonotum subopaque, with a smooth, shin- 

 ing band down the middle and along each parapsidal furrow ; with the 

 exception of these regions the whole surface is covered with large elongate- 

 elliptical foveolae, the spaces between which are more finely punctate and 

 raised into indistinct longitudinal rugae. Paraptera and scutellum shining, 

 with transversely elliptical foveolae which are almost absent in the middle 

 of the latter sclerite. Mesopleurae shining and foveolate like the mesonotum. 

 Surface of metanotum irregularly foveolate and in addition covered with 

 fine, more or less longitudinal rugae. Epinotum very opaque, densely 

 punctate above and longitudinally rugose below. In the region between 

 the teeth and the ridges running backwards and downwards from them, 

 the surface is crossed by rather coarse transverse rugae. Convex dorsal 

 surface of petiole very smooth and shining, finely and sparsely punctate 

 and with a few round foveolae which are most numerous along the posterior

edge and the sides of the node ; concave posterior dorsal declivity and the 

 whole ventral surface of the petiole opaque, very finely and densely punc- 

 tate, the former in addition with indistinct rugae radiating from the poste- 

 rior edge of the segment. Postpetiole above in the middle shining, with sev- 

 eral round foveolae, which on the sides become prolonged backwards so 

 that the surface has a somewhat grooved appearance ; lower surface opaque 

 and densely punctate like the lower surface of the petiole. Gaster shining, 

 the segments smooth and very finely and sparsely punctate at their bases 

 but more opaque and evenly reticulate along their distal borders. In ad- 

 dition to this sculpturing there is a small cluster of impressed reticula- 

 tions around the insertion of each hair. Legs coarsely punctate-foveolate. 

 Body, except the epinotum, covered with tawny hairs which are rela- 

 tively shorter than in the worker. On the head, thorax and femora the 

 hairs are erect, on the petiole, postpetiole and gaster suberect, on the an- 

 tennae, tibiae and tarsi shorter and more appressed. Wings covered with 

 minute black hairs.
