WASP-GENUS PARALASTOR. 609 
ex parte maxima, maculis 2 rotundatis scutellaribus, duabus 
minutis mesopleuralibus, fascia latissima segmenti 1 abdominalis, 
faseia secundi fere recta et, quam fascia prima, multo minus lata, 
tibiis tarsisque omnibus, rufescentibus. Clypeus truncatus, ex 
majore parte dense, subtiliter ruguloso-punctatus. Mesonotum 
posterius irregulariter aut vix dense punctatum, postscutello 
inermi. Tegule vix nitide, ex majore parte subtilissime, vix 
evidenter sculpturate, puncturatione minutissima distincta 
carentes. Abdominis segmentum primum haud  fortissime 
transversum, parte declivi excepta fere totum rufum; secundum 
elongatum, lateribus fere parallelis, basi haudquaquam convexim 
elevata. Segmentum 2 ventrale post sulcum fortissime elevatum, 
elevatione summa fortissime prominente, tuberculum fortem 
formante. Long. 9 mm. 
I have seen only a single female of this distinct species and 
it is in dirty condition. The wings appear to be infuscate, but 
this may be partly due to this condition. In any case the costal 
portion is much darker than the rest. 
Hab. Australia, Champion Bay; 1 9 in the British Museum. 
74, PARALASTOR CARINATUS Sm. (? LATERITIUS Sauss., var.). 
I have before me a single female from the Oxford Museum, 
which I refer, as a slight variety, to this species. It has a pair of 
small orange basal spots on the clypeus, and the black colour of the 
second abdominal segment is more extensive, forming a basal 
band, angulated in the middle and with irregular sinuations on 
each side of this. The clypeus is truncate, punctate, and more or 
less strigose, turned upwards on its apical portion, and with a 
fovea in the middle adjoining the apical margin. There is in 
some aspects a faint trace of tuberculation in the middle line of 
the postscutellum. The second ventral segment is very strongly 
raised behind the transverse sulcature, and somewhat pointedly 
produced in the middle at the top of the truncation ; it is rather 
finely and not very unevenly punctured, with very distinct 
interstitial minute puncturation. 
Hab, Adelaide, 1 9, Oxford Museum. The type is in the 
British Museum and must nearly, if not altogether, agree with 
the Oxford specimen, except in slight points of colour, which vary 
shnilarly in other species.
