Of rather stout build, for this genus large ; colour deep reddish- 
lu’own or blackish, scarcely punctate. 
Head broad, sutures distinct ; occii)ut rectangular ; eyes anterior 
and relatively small. 
Antennae with 16 segments, two or three praeapical segments 
yellowish ; 3rd segment long and cylindrical ; 4th ovate, about half 
as long as the 3rd ; the rest gradually lengthening, the apical segments 
about equalling the 3rd. 
Pronotum distinctly broader than long, rectangular. 
Mesonotum a little shorter and a little broader than the pronotum, 
with no keel. 
Legs long and slender, typical of the sub-family, yellow, the femora 
and tibiae banded with black. 
Abdomen somewhat dilated about the middle, tapering apically, 
typical. 
Penultimate ventral segment narrowly rounded. 
Forceps subcontiguou.s, rounded, rapidly tapering. 
Australia : Queensland, Cooktown (coll. Brunner, 
No. 20, 162, 1 ?). 
Although this specimen is a female, and no male is 
known, the characters are so Avell marked that the species 
can be easily recognized, apart from the fact that it is the 
only known Australian member of the sub-family, except 
the doubtful B. geniculata. 
I place it in Nannisolabis on account of its small eyes 
and smooth pronotum, but in its broad head and transverse 
pronotum it differs from the other two known species, as 
also in the long antennal segments; a new genus must be 
erected for it when the male is discovered. This new genus 
will stand in the same relation to Nannisolabis that Leptiso- 
labis stands to Isolabis and Cte7iisolabis to Mdisolahis. 
The type is in the Brunner collection, now in the Hof- 
mnseum in Vienna.
