WASP GENU PARALASTOR. 6i1 
dilatata, et fere ad basum segmenti extensa, rufis aut rufescen- 
tibus. Clypeus latus, truncatus, subeequaliter punctatus, et 
minutissime punctulatus. Mesonotum crebre fortiter punc- 
tatum, scutello inermi, tegulis nitidis, punctis majoribus non- 
nullis, param fortiter impressis, presentibus. Ale infuscate, 
parte costali saturatiore. Abdominis segmentum secundum 
dorsale ad basim subfortiter convexum; ventrale, post suleum, 
sat abrupte elevatum, parte antesulcali parti postsulcali alti- 
tudine subquali, elevatione summa haudquaquam prominente. 
Long. 9-10 mm. 
With this species begins a series of forms with the hind part 
of the second ventral segment raised only to about the height of 
the basal portion, and with the clypeus always truncate apically. 
Hab. Victoria (French); 2 2, Sept. 1901. The two examples 
have a quite different pattern of the second abdominal segment, 
and they are in a dirty condition.

2. Nigra, macula clypeicurvata basali, notis 2 postocularibus, 
duabus maculis pronotalibus, nonnunquam notis 2 scutellaribus, 
margine postico segmentorum 2 basalium abdominis angustius, 
flavis. Clypeus truncatus aut paullo antice rotundatus, fortiter 
equaliter punctatus. Frons capitis cum mesonoto dense punc- 
tata, pilisque brevioribus sat crebre vestita, scutello inermi. 
Tegule nitide, parum distincte sculpturate. Abdominis seg- 
mentum primum fortiter transversum; secundum ad_ basim 
fortiter convexum, pilis erectis brevioribus ubique, nec dense, 
vestitum ; secundum ventrale, ut in precedente formatum. 
Al fusco-hyaline, parte costali multo magis infuscata. Tibi 
tarsique rufescentes. Long. 9-10 mm.

80. PARALASTOR SUBPLEBEIUS, sp. n. (PI. I. fig. 15.) 
2 precedenti cognatissima, sed major, fasciis abdominalibus 
minus angustis, flavo-aurantiacis, segmento primo abdominis 
conspicue transversim depresso, facile distinguenda. Long. 
12 mm. 
This is probably the representative in Queensland of P. plebeius, 
but, apart from colour, the form of the basal abdominal segment 
is too distinct to permit the two to be considered as varieties of 
one species. 
Hab. North Queensland (Dodd), 2 2.

Color fere P. pusilli Sauss. et P. simulatoris mihi. Fascize 
abdominales bicolores, antice rufescentes aut subaurantiacie, 
postice flave. -clypeus flavus, 2 parte posteriori sola flava
