WASP-GENUS PARALASTOR. 583 
14, PARALASTOR HABILIS, sp. n. 
Abdomen nigrum, segmento secundo pallide flavo, macula, 
magna subtriangulari nigra, ad aut post medium segmentum 
extensa, signato. o clypeus, macula interantennalis, articulus 
antennarum primus antice, macule parve verticis postoculares, 
macule pronotales (nonnunquam fasciam fere integram 
formantes), pallide flava; @ clypeus antice niger, postice 
aurantiacus ; antennarum articulus primus (basi extrema pallida 
excepta) niger. Ale hyaline, costali parte infuscata, plus minus 
flavescente. _Tarsi posteriores, articulo ultimo excepto, nigri 
aut atro-fusci ; tibie aut nigricantes aut rufescentes. 
Clypeus distincte, nee profunde emarginatus; frons grosse 
punctata. Mesonotum, quam densissime, rugoso-punctatum, 
parum dense pilosum; tegulis nigris, grosse usque ad marginem 
exteriorem punctatis ; posteutellum haud aut vix tuberculatum. 
Abdominis segmentum primum pernigrum, dense punctatum, 
inter puncta quasi subtilissime granulatum, secundi pars nigra 
similiter sculpturata, sed remote punctata ; segmentum 2 ventrale 
post suleum fortissime abrupte elevatum, elevatione summa 
prominula; septimum segmentum ¢ ventrale latum, lateque 
impressum, parum conspicue pilosum, pubescentia brevi vestitum. 
Long. 11-13 mm.

15. PARALASTOR SUBHABILIS, Sp. 0. 
Precedenti simillimus, ut apparet, paullo gracilior, alarum parte 
costali magis flavescente, et ibidem venis pallidioribus. Tarsi 
posteriores ubique, aut ex majore parte, pallidi.  Tegule, 
marginem exteriorem versus, pallide. Segmentum tertium 
abdominale plerumque flavo-marginatum, aut plus minusve 
pallidum, rare nigricans, sequentibus segmentis etiam spe 
pallidis. . 
Possibly only a race of the preceding, but superficially quite 
distinct. The pattern of the second abdominal segment is different 
from that of Aabilis, the black median marking narrower and not 
of the same subtriangular form. Unless it has become changed 
post mortem, the ground-colour is also different, the yellow more 
ochreous, or in some examples approaching orange, not pale clear 
yellow or whitish yellow. The colour of the clypeus in the female 
is not constant ; sometimes it is nearly entirely yellow, sometimes 
black on the apical part. 
Hab. Queensland, Mackay, 6 examples (Zurner) ; Queensland, 
1 S$ from EK. Saunders’s collection. 
16. PARALASTOR FLAVICEPS Sauss. 
I have not examined the type of this species, but should the 
tegule have a very coarse puncturation extending to the outer 
margin, then it would be placed in my table next to habilis and
