WASP-GENUS PARALASTOR. 615 
apical band. The structure of the second dorsal segment apically 
is rather different from either species, but, in the absence of the 
male sex of the others, it is too close to be worth describing as 
distinct. This male was taken on March 15th, 1902, by Mr. F. 
P. Dodd. 
Hab. Queensiand, Cairns, 1 2. 
87. PARALASTOR PICTETI Sauss. 
With this species begins a series of allied forms, forming my 
second division. It is Saussure’s division of Alastor picteti, 
which he characterized as having the abdomen subpetiolate. 
All the specimens of picteti that I have seen come from Queens- 
land. The details of coloration in this species vary a little, and 
I think none exactly agrees with Saussure’s description. He 
gives “ Tasmania ” as the locality for his insect, but, as with 
some other species already referred to, I doubt the correctness 
of this. The tegule are for the most part smooth and polished. 
Hab. Queensland, Bundaberg and Cairns, taken by myself ; 
Mackay, three bad specimens (Z’wrner); Kuranda, May to June, 
1913, eleven examples. 
88. PARALASTOR CONSTRICTUS, Sp. n. 
@. Nigra, clypei parte basali nigra, apice lateribusque flavis, 
picturatione variabili. Macula interantennalis, margines oculares 
antice posticeque plus minus—variabiles tamen sunt—pronoti 
fascia irregularis anterior, ad tegulas lineatim utrinque producta, 
macule scutellares, postscutellares, propodeales et mesopleurales, 
segmentum abdominale (parte declivi excepta) ex majore parte 
primum, fascia secundi lata cum duabus maculis magnis basalibus, 
et segmentorum fascie sequentium, aurantiaca. Pedes fulves- 
centes, femorum parte apicali sepe flavo-notata. Antennarum 
articulus primus antice flavescens aut fulvus, flagello seepe subtus 
rufescente. Clypeus truncatus aut vix emarginatus, margine 
apicali recto aut perpaullo concavo, fortiter punctatus, punctura- 
tione minuta interstitiali distinctissima. Frons cum thorace 
pilis erectis brevioribus suberebre vestita, capite densissime punc- 
tato. Mesonotum densissime grosse punctatum, puncturatione 
distinctissima, sed subrugosa. Ale subhyaline, costali parte 
fusco-flavescente, stigmate pallido, cellula marginali infumata. 
Tegule ex magna parte leves, polite. Abdominis segmentum 
primum grosse, sepe rugose punctatum, parte basali segmenti 
secundi remote aut irregulariter punctata. Long. 9-11 mm. 
I-have seen only five examples of this species and no two are 
alike in details of markings or sculpture, but I think they 
certainly all belong to a single species. 
Hab. Queensland, Bundaberg, 2 9, taken by myself (June 
1904); 1 2, Queensland (ea coll. H. Sawnders); Mackay (Turner),
