prominente sive tuberculiformi. Tibie ferruginee, intermedize 
et posteriores intra infuscate sive nigricantes, his supra flavo-

Hab. W. Australia; 1 2 in the British Museum. 
34. PARALASTOR TRICOLOR, sp.n. (PI. I. fig. 5.) 
2 colore P. despecto simillima, sed postscutello haud binotato, 
scutello bimaculato, mesopleuris notatis, abdominis segmento 
secundo minus late fasciate, fascia fere recta. 
3 clypeus flavus aut flavus et aurantiacus, medius fusco- aut 
nigro-maculatus, Antennarum articulus primus rufescens, 
antice flavescens, secundus nonununguam rufescens. Macula 
interantennalis, macule pronotales, scutellares et mesopleurales 
aurantiace, aut plus minus flavescentes aut rufescentes. Tegule 
rufescentes aut flavo-variegate. Abdominis segmentum primun 
supra rufum, antice nigro-emarginatum, postice flavo-mar- 
ginatum. ‘Tibiz tarsique rufescentes. 
' Q ac 6 fere similiter colorata, sed clypeus ex magna parte 
est niger, lateribus flavis aut aurantiacis, tibiis supra sepe longe 
flavescentibus. 
3 clypeus distincte nec profunde emarginatus, parce pune- 
tatus, puncturatione minutissima, inter puncta majora, distincta. 
2 clypeus plerumque levius, quam maris, emarginatus, et 
crebrius, distinctissime punctatus. Mesonotum fortiter denseque 
punctatum, postscutello inermi, propodeo rotundato, distincte 
punctato, angulis pronotalibus parum distinctis. Abdominis 
segmentum secundum dorsale pilis erectis, haud densis (et facile 
detritis), ubique vestitum, basim versus (precipue ¢) sat con- 
vexum. Segmentum 2 ventrale fortissime post suleum trans- 
versum elevatum, elevatione summa prominula, Segmentorum 
sequentium apices sepe aurantiace, aut plus minus pallide. 
Alarum pars costalis distinete infuscata, partibus ceteris leviter 
infuscatis. ¢ antenne 1] articulate ,articulis 3 ultimis minutis, 
? haud plus quam solito insvassate. Long. 8-9 min. 
This species somewhat resembles the preceding P. despectus, 
but is probably not very closely allied, as the female—this being 
the only sex known of the other—has the elypeus much less short 
and much less convex, and the punctures are much less close. 
The second ventral abdominal segment is more strongly raised, 
the top of the truncation in the middle being of more pointed 
form, the second dorsal segment less abruptly and strongly raised 
from the base ete., and the coloration of the insect is brighter. 
It is excessively like P. picteti Sauss. in the other section of the 
genus. The emargination of the clypeus is very shallow in some 
females, rather deeper in others.
