MEMOIRS OF TIIE QUE,EN SLANT) MUSEUM. 
broad ; clypeus shining, with widely scattered punctures, no median sulcus ; 
flagellum with a very faint reddish tinge beneath ; mesothorax entirely dull, 
the punctures so tine as to be hardly visible under a lens, but the microscope 
shows excessively dense small punctures ; middle of postscutellum with dense 
pale tomentum ; area of metathorax large, poorly defined, almost without 
distinct sculpture, but the microscope shows fine plicae at the base ; there is no 
shining rim ; tegulae very dark brown, almost black ; wings greyish hyaline, with no 
evident apical cloud ; stigma and nervines dull rufous ; basal nervure very 
strongly bent, and ending a long distance from nervulus ; second cubital cell 
higher than broad ; first recurrent nervure meeting intercubitus, or going to 
apical corner of second cubital cell ; legs black, with thick pale hair, spurs 
ferruginous ; abdomen very broad, dull dark red, finely punctured, black beyond 
the third tergite ; no hair -patches ; venter with white hair ; second sternite 
simple. Orange pollen (round grains, without spicules) has been collected on 
the hind femora and tibiae, and the base of the abdomen beneath. 
Stanthorpe, Queensland, Nov. 3, 1922 (F. A. Perkins) ; Queensland 
Museum. Also runs to P. lichatus in my table, and suggestive of P. 
Mrtiventris Ckll., but quite distinct. The peculiar basal nervure is a good 
recognition mark. 
Parasphecodes bribiensiformis sp. n. 
Female. Like P. bribiensis Ckll., but area of metathorax much larger, 
subtriangular, with coarse though irregular plicae ; first abdominal tergite 
considerably broader, being much broader than long ; base of second tergite 
pellucid whitish except at extreme sides ; tegulae piceous with a red spot (fulvo- 
testaceous in P. bribiensis) ; hair of scutellum very pale fulvous. 
Bribie Island, Queensland, Aug. 29, 1920 ( Hacker ) ; Queensland Museum. 
I hesitated whether to call this a variety of P. bribiensis, or a distinct species ; 
but the area of metathorax is so different that it must apparently be separated. 
The species of this group, with brown abdomen, and bosses on the first 
two tergites, are neither true Parasphecodes nor true Halictus. They may form 
a subgenus Aphalictus subg. n., probably to be treated as a genus when 
structural studies of both sexes can be made. The type of the subgenus is 
P. bribiensis Ckll. 
Halictus moreensis sp. n. 
Female. Length about 8 mm. ; robust, black, with very broad abdomen 
(its width over 3 mm.) ; tibiae and tarsi entirely clear bright ferruginous ; legs 
otherwise reddish brown, with the femora clear red apically ; head broad ; 
mandibles rufous in middle ; scape black, flagellum ferruginous beneath ; 
clypeus shining, punctate, convex, with no median sulcus ; hair of head grey, 
rather abundant ; front minutely striate ; mesothorax and scutellum with short, 
rather dense, pale-fulvous hair ; postscutellum with paler tomentum, very dense 
in middle ; mesothorax dullish, scutellum shining, not bigibbous ; area of 
metathorax semilunar, not at all pointed behind, and with no shining rim, the
