WASP-GENUS PARALASTOR. 619 
rufescens, segmento primo ante fasciam apicalem, latam, albido- 
flavam, nonnunquam nigro, secundo fascia fere simplici lata ornato, 
maculaque utrinque magna basali, pallide flava aut albida decorato. 
Clypeus levissime, sed sat distincte,emarginatus. Long. 7°5 mm. 
Allied to the preceding, with generally similar sculpture and 
the apical margin of the second abdominal segment similarly de- 
pressed and wide. Easily distinguished by the fairly numerous 
and conspicuous large punctures of the tegule, and the rougher 
postscutellum, which is rather differently formed, 
Hab. Central Australia, Hermannsburg, 2 2 (4H. J. Hillier). 
The specimens are not in very good condition, the one which is 
not mutilated being probably somewhat discoloured. 
94, PARALASTOR SIMILLIMUS, Sp. n. 
Picturatio et color fere P. constricti (q. v.), sed statura minore. 
Clypeus ¢ flavus, 2 macula parva nigrescente signatus, apice 
truncato, aut vix evidenter emarginato. 
2 clypeo obsoletius punctato (se. punctis parum fortiter im- 
pressis), antennis crassioribus, tegulis opacis aut vix unitidis, 
puncta grossiora ferentibus, distinguenda. Long. 8 mm. 
As the female of this species is unique and the male of P. con- 
strictus is unknown, I have only been able to compare this female 
example with the latter species, and unfortunately I do not feel 
quite sure that this single female belongs to the males that I a ssign 
to simillimus. On account of the better material, I have taken a 
male as the type and not this unique female. It lacks the pair of 
large basal spots on the second abdominal segment at the base and 
the tegule are less punctured than in the male. Seen in profile, 
the second segment is much more evenly rounded above than in 
P. constrictus, and this is also, to a less extent, true of the male, 
The male has the tegule very coarsely punctured over nearly the 
whole surface, the clypeal punctures are feebly impressed and the 
apex of the clypeus is truncate or almost so. The general 
sculpture is nearly the same as that of constrictus. The second 
ventral segment is not flattened or slightly depressed behind the 
transverse sulcus as it is in constrictus. The apical ventral 
segment has a very short pubescence, which is decumbent or sub- 
decumbent. 
The species is quite distinct, and it is highly probable that the 
sexes are correctly associated. 
Hab. Queensland, Mackay (Zurner), 1 g, 1 9. I took the 
former sex at Bundaberg, but no °.
