$ . Head broader than the thorax, smooth and shining, 

 the face very minutely punctured. Clypeus truncate at the 

 apex, the labrum slightly exposed; ciieeks long, only a little 

 shorter than the eyes; frontal excavation deep. Tiiorax 

 smooth and shining, the median lobe of the mesonotum 

 rather prominent ; parapsidal furrows well marked, very 

 finely crenulated in the middle, the extremities smooth ; a 

 curved and strongly longitudinally striated depression at the 

 base of the scutellum. Median segment densely covered 

 with whitish hairs, not areolate. Abdomen smooth and

 First discoidal cell sessile, nervulus slightly postfurcal, anal 

 cell of fore wing with two transverse nervures, the second

In the Victorian specimen the white hairs spread on to 

 the sides of the second tergite. The species is not a typical 

 Gymnoscelus, differing in tiie sliape of the second cubital cell 

 and in the partial effacement of tlie second transverse vein of 

 the anal cell. It forms a link between Gymnoscelus and 

 'I t ichiuhelco/i, differing hom the latter in the absence of a
