1 specimen from Uspallata in the province of Mendoza. 
A much wider ranging species than most of the family, but 
does not seem to be plentiful, being rare in collections.

2 The seventh dorsal segment of the abdomen is much 
longer than broad, deflexed and narrowly truncate at the apex, 
the lateral margins raised near the apex; the hypopygium scar- 
cely projecting beyond the seventh dorsal segment, rather broad. 
ending in a short apical spine with a short blunt lobe on each side 
of it. The clypeus is strongly porrect as noticed by Kuuc. The 
division of the first cubital cell is distinetly marked. The mandibles 
are strongly bent, flattened and bidentate, the inner tooth short and 
not truncate. 
2. Clypeus short, broadly emarginate; labrum exposed, truncate 
at the apex and strongly ciliated. Mandibles pointed at the apex. 
Head nearly twice as broad anteriorly as long, strongly rounded 
posteriorly, sparsely punctured, with a deep, longitudinal, frontal 
suleus. Pronotum shining, much narrower than the head, nearly 
twice as broad as long, strongly concavely depressed anteriorly, the 
lateral and posterior margins raised. Scutellum very small and 
narrow; the median segment raised into a shining hump-like tubercle 
at the base, obliquely truncated just behind the tubercle, the sur- 
face of the truncation rather narrowly triangular and shagreened. 
Abdomen ovate, sparsely punctured; the basal segment with a shallow 
transverse groove before the apex, the second segment coarsely 
transversely rugose, with a transverse carina near the apex sepa- 
rated from the raised apical margin by a smooth and broad grove. 
Pygidium not truncate or compressed, longer than broad, longitudi- 
nally rugose-striate, smooth and slightly rounded at the apex, the 
ventral plate not projecting beyond the dorsal. The ventral segments
