 each bearing a single long seta and two short spinelike ones. Discal 

 setae of pronotum very short, spinelike; marginal setae equally 

 spaced, the middle pair being slightly the longest. Prosternal plate 

 with very broad chitinous margins. It has a single pair of long setae 

 and about a dozen short spinelike ones.

 dorsal suture, more than twice as broad as long. It is outwardly 

 rounded behind, has an enormously thickened anterior wall and no 

 dorsal setae.
