WASP-GENUS PARALASTOR. 603 
have the same dense, distinct, minute puncturation and the clypeus 
is nearly of the same form, as also is the general sculpture. The 
postscutellum has even less evidence of a tubercle than that of the 
preceding species. Length about 15 mm. 
Hab. Australia, without definite locality; 1 2 in the British 
Museum. Judging from the coloration, one would expect to find 
this species in Queensland. 
60. PARALASTOR DENTIGER, sp. n. (PI. I. fig. 11.) 
3 colore et picturatione fere P. mimi (q.v.) ornatus. Notex 
postoculares minores, clypeo aurantiaco, margine apicali et non- 
nunquam linea mediana nigris. Alee ubique infuscate. Clypeus 
fortiter emarginatus, nitidus, parte media nitida, glabra, de- 
planata, basi lateribusque decurvatis et dense argenteo-pubescenti- 
bus. Frons dense et rugose punctata. Mesonotum densissime 
punctatum, postscutello tuberculo spinoso conspicue armato, 
tegulis puncturatione densissima et minutissima carentibus, sed 
punctis nonnullis majoribus plerumque distinctis. Abdominis 
segmentum primum transversim subdepressum, plus minusve 
rugoso-punctatum, colore rufo antice profunde, sed anguste, nigro- 
emarginato; segmentum secundum dorsale basim versus leviter 
convexum ; ventrale, post sulcum suum transversum, fortissime 
elevatum, elevatione summa prominente; segmentum ultimum 
cum precedentibus pilis erectis evidenter vestitum. Antennz 
1l-articulate, tribus apicalibus articulis minutis. Long. 11-5 mm. 
This is a more robust species than P. mimus and imitator, which 
it so much resembles superficially. The posterior face of the 
propodeum is more extensively black than in the former. Struc- 
turally it is entirely distinct from both. 
Hab. Champion Bay and Swan River; 2 ¢ in the British 
Museum. 
61. PARALASTOR INFIMUS, Sp. n. 
3 picturatione, forma, et colore P. eriurgo simillimus, sed apice 
clypei haud distinctissime elevato-marginato, et scutello sat 
conspicue tuberculato bene distinguendus. Clypeus leviter 
emarginatus, grosse punctatus, nitidus, basi lateribusque dense 
argenteo-pubescentibus. Frons dense rugoso-punctata. Tegulee 
densissime et minutissime punctulate. Thorax sat grosse punc- 
tatus, pilis erectis ubique conspicue vestitus. Abdominis seg- 
mentum primum medium impressum, margine apicali excepto, 
crebre punctatum. Abdominis segmentum 2 ventrale, post 
suleum fortissime elevatum, subopacum, crebre punctatum, 
elevatione summa prominula, hoe segmento cum sequentibus 
pilis erectis fere xquilongis vestito, segmento ultimo spatium 
medianum nitidius, lineis elevatulis definitum, prabente. Long.
