Compared with the above description of parviclavus diifers as 

 follows: Frontal horn larger and stout conical; eyes weakly con- 

 vergent, comprising nearly two-thirds total width of head at an- 

 tennae ; occipital carina in side view convergent above with posterior 

 margin of eye, more prominent and with a deep notch just before 

 its junction with the hypostomal carina, latter high beyond junc- 

 tion; temples hardly a third as long as short diameter of eye; 

 diameter of an ocellus fully two-thirds as long as ocell-ocular line 

 and much longer than postocellar line; basal joint of flagellum not 

 quite so slender. Anterior lateral carina of pronotum high ; epomia 

 strong below, obsolete above; mesopleural furrow distinctly foveo- 

 late; metapleurum obliquely rugose in posterior half; spiracles 

 broadly oval; apophyses rather long, compressed; areolet rather
