WASP-GENUS PARALASTOR. 695 
fortissime elevatum, elevatione summa haudquaquam acute 
prominente, fortiter punctatum. Long. circiter 9 mm. 
Very distinct from any of the preceding species by its colour, 
narrow elongate form, the longer first abdominal segment, lone 
subparallel- -sided second segment, ete. It might almost be placed 
in the other division of the! species here described, and is included 
in the tables of both divisions. 
Hab. Australia, Swan River, 3 2 (two in the Oxford and one 
in the British Museum); 1 @2 in very bad condition is labelled 
‘** New South Wales,” probably in error. 
43. PARALASTOR IMiITATOR, sp.n. (PI. I. fig. 10.) 
2. Preecedenti simillima, sed minor, tegulis grosse punctatis, 
puncturatione minutissima absente, antennis brevibus et crassis 
facile distinguenda. 
Form, colour, and general appearance almost exactly as in 
P. mimus. In the single specimen the clypeus is black on about 
the apical third, its apex is very lightly emarginate. The fourth, 
fifth, and sixth antennal joints are extremely strongly transverse. 
The tegule are very shining, conspicuously, coarsely, and deeply 
punctured, and without the numerous minute punctures that 
form the chief sculpture in P?. mimus. The wings are still clearer, 
with very little infuscation along the costa. ‘The basal abdominal 
segment is rather shorter and the second less abruptly narrowed 
at the base. The second ventral segment 1s considerably less 
strongly raised behind the transverse sulcus. Long. 7°D mm. 
This species is very distinct.

3. Niger, clypeo, antennarum articulo primo antice, maculaque 
postoculari minuta, flavescentibus. Pronoti fascia, utrinque 
dilatata, pars tegularum exterior, note parve scutelli due, fascia 
sat lata postscutellaris, abdominis segmentum primum, parte 
declivi excepta, faseia secundi apicalis, aurantiaca aut aurantiaco- 
rufa. Tibiee ferruginez, tarsis ex majore parte fusco-brunneis. 
Clypeus brevis, sat convexus, apice levissime emarginato, dense 
argenteo-pubescens. Frons capitis pilis crebre vestita. Pronoti 
truncatio fere recta, aut perpaullo concava, distincte elevato- 
marginata. Mesonotum densissime fortiter punctatum, scutello 
similiter punctato, postscutello inermi. Tegule nitide, grosse 
et conspicue punctate. Abdominis segmentum primum, quam 
densissime, grosse punctatum, secundum etiam densissime ubigue 
punctatum, basi fortiter convexim elevata. Segmentum 2 
ventrale post suleum transversum distincte (sed haud fortissime) 
supra partem basalem suam elevatum, elevatione summa haud- 
quaquam acutius producta, post hance late et conspicue im-
