This species, in the length of the ovipositor of the female, 
forms a connecting link between Sporetus and Trichonius ; the 
terminal dorsal plate, although short and broad, is pointed at 
the apex, and not rounded off as in Trichonius. 
§ 2. Ovipositor of the 9 long, projecting to the length of a line beyond 
the tips of the elytra; dorsal plate taperizig to a sharp point.
