The most conspicuous character of this species is the peculiar 

 sculpture of its pronotum. The front part of the segment is 

 obliquely slightly retuse; from the middle of the summit of the 

 declivity three deep sulci proceed (they do not, however, quite 

 meet at the summit), one of them longitudinally to the front 

 margin of the pronotum, one on each side towards the lateral 

 margin (widening out and becoming obsolete, however, and so not 

 reaching the lateral margin). It is quite probable that in the 

 other sex this sculpture is at least enfeebled, but disregarding it 

 the insect is extremely distinct from all the preceding (of the 

 Third Group) by the well-defined extero-f ront angles of its frontal 

 wings and by its hind femora quite punctureless between their 

 extreme front margin and the row of setiferous punctures near 

 the hind margin.
