600 DR. R. CG. L. PERKINS ON THE 
common on the mainland. Two other species, P. picteti and 
P. tasmaniensis, recorded from Tasmania, are known to me only 
from Queensland, and the possibility of error in Saussure’s 
localities seems to be considerable. 
53. PARALASTOR NAUTARUM Sauss. 
This species, described on a single male, should probably be 
placed near P. orientalis, as I have a note that the tegule are 
very coarsely punctured, the clypeus distinctly, but not deeply, 
emarginate. Superficially at least it is quite distinct from this 
or allied forms, by the first segment of the abdomen being orange 
with a black spot on its declivous basal portion, the second and 
following ones being entirely black. The ventral surface of the 
abdomen has a short dense pubescence.

3g. P. orientali colore et vestitu simillimus, sed minor, orbitis 
interioribus aurantiaco-fasciatis, maculis postocularibus magnis, 
elongatis, ante medium oculorum marginem exteriorem extensis, 
fascia pronotali haud ad tegulas extensa, tegulis ipsis inter puncta 
majora minutissime punctulatis, abdominis segmento 2 ventrali, 
post suleum, multo minus fortiter elevato, elevatione summa haud 
aut vix antice producta, facillime distinguendus. Long. circiter 
7 mm. 
T have seen only one example of this species, which in general 
appearance and sculpture resembles P. orientalis. The orange of 
the basal segment is emarginate with black in the middle in front, 
as in the other, but the second segment is less conspicuously deep 
black, owing to the less dense tomentum, and the puncturation 
therefore appears much more distinct. The tegule bear less 
numerous punctures than is usual in this group.
