584 DR. R. CG. L. PERKINS ON THE 
subhabilis, being easily distinguised by its “ téte jaune de soufre ; 
sur le vertex un ovale noir, qui enveloppe les ocelles” (Saussure). 
In any ease this character of coloration will distinguish it from 
any other of the species that have the first abdominal segment 
wholly black. 
Hab. Australia. 
17. PARALASTOR ALBIFRONS Fabr. 
I have not examined the type of this species, but Mr. Meade- 
Waldo has very kindly examined it for me, as to certain 
structural points, from which I infer it should be placed next to 
P. habilis. In fact, I do not feel sure that the latter may not be 
a variety or race of the Fabrician species. 
Hab. Australia (Banks collection). 
18. PARALASTOR APICATUS Sin. 
Tbe type specimen is from Aru, Examples from Papua 
(Odynerus lorentzi Cam.) are at the most slight colour-varieties, 
quite unworthy of a special name. The tegule are punctured on 
their inner portion, smooth and polished outwardly ; the second 
abdominal segment seen in profile rises up strongly above the 
level of the first; ventrally, it rises up strongly, but rather 
obliquely, from the transverse suleus, and the truncation is not at 
all prominent or produced forwards at its highest point. 
Hab. Aru (Wallace), type in the British Museum and 1 ¢ in 
the Oxford Museum. I have seen several examples from New 
Guinea. 
19. PARALASTOR PALLIDUS, Sp. n. 
2. Nigra, clypeo flavo-bimaculato, aut macula curvata basali 
ornato. Frons interantennalis flavo-maculata ; macule pronotales 
flavescentes. Tegule externe flavescentes aut rufo-flave. 
Abdominis segmentum secundum  ochraceo-flavum, macula 
triangulari basali signatum, sequentibus similiter pallide coloratis, 
margine etiam primi postico pallide fasciato, fascia hac media 
emarginata. Femorum apices, tibie, tarsique rufescentia. Ale 
subhyaline, parte costali infuscata. Clypeus nitidus, iregulariter 
punctatus, apice distincte, nec profunde, emarginato, margine 
elevato. Mesonotum densissime punctatum, postscutello inermi. 
Abdominis segmentum primum obscurius punctatum, secundum 
ventrale fortissime post sulcum abrupte elevatum, elevatione 
summa prominente. Tegule ex magna parte dense distinctissime 
et subtilissime punctate. 
Unlike any other species superficially. The second dorsal 
segment is only a little more than ordinarily convex on its basal 
portion.
