WASP-GENUS PARALASTOR. 607 
2 ventrale, post sulcum, fortissime elevatum, elevatione summa 
prominente. Long. 11-5 mm. 
The clypeus is wide and much less produced than in P. vul- 
neratus, and is only feebly emarginate, but it is flattened in the 
same perfect manner, and the “front, between the antenne, is. 
similarly flattened. The raised smooth lines of the front of the 
head are found only in this and the following allied form. The 
femora all have a conspicuous yellow apical spot outwardly, which 
contrasts strongly with the ferruginous tibiz and tarsi. 
Hab. Queensland, Brisbane. I captured 1 @ on Christmas 
Day, 1904. 
69. PARALASTOR MACKAYENSIS, sp. n. 
2 structura preecedenti fere similis, sed abdomine flavo-ornato, 
pedibus pallidioribus, fascia prima abdominali antice sat profunde 
nigro-emarginata, pronoti maculis multo minoribus, scutello post- 
scutelloque binotatis, haud fasciatis, distinguenda. 
In the very poor material at my disposal I see no structural 
character that could be relied on, as constant, to separate this 
form from the preceding, of which it is probably a more northern 
race. In markings and in colour of the markings the two are 
very distinct, the deep orange colour of brisbanensis being 
replaced by a more ochreous or pale orange in mackayensis.
