MEMOIRS OF TEE QUEENSLAND MUSEUM. 
by the much broader face, and the much more finely punctured first abdominal 
segment. 1 take pleasure in naming it after Heber A. Longman, the Director of 
the Queensland Museum, in recognition of his important services to Queensland 
zoology. 
Hylaeus semipersonatus n. sp. 
Male. Length about 4*5 mm. ; slender, but not excessively so ; black, with 
the face creamy white up to level of top of the long clypeus (except a narrow black 
mark at each side of clypeus), leaving a broad black area between the light colour 
and the antennae, which are placed high up ; face narrow, inner orbits convex ; 
mandibles black with a small light spot at base, and apex reddened ; labrum black : 
scape very broad, broadly yellowish white in front ; flagellum rather long, dull 
red beneath ; malar space well developed, longitudinally striate ; ocelli in a triangle : 
mesothorax somewhat shining, with a deep median groove, the surface microscopically 
lineolate and punctured ; seutellum shining ; area of metathorax large, dullish ; 
thorax all black except the tubercles apically cream colour ; leglike dark ; wings 
greyish hyaline ; stigma unusually small, very dark reddish ; basal nervure falling 
short of nervulus ; second cubital cell receiving recurrent nervures about equally 
distant from base and apex ; legs black, with anterior tibiae in front, spot at base 
of middle tibiae, and base of hind tibiae broadly, creamy white ; abdomen shining. 
Cradle Mountain, Jan. 18, 1917 (G. H. Hardy). A distinct little species, 
easily know n by the partly masked face, with dark femora and mainly black mandibles. 
Hylaeus fijiensis (Cockerell). 
In 1909 I described the splendid blue Prosopis fijiensis from a female in the 
British Museum, which had belonged to Smith. It was labelled as from the Fiji 
Islands. Now I find a female in the collection of the Queensland Museum, labelled 
Rye, Victoria, Dec. 1918 (L. Barber). One or the other locality must be wrong. 
The species seems out of place in the fauna of Victoria, and is in fact very different 
from anything known in Australia, with the exception of Palceorhiza gigantea Ckll., 
1926, from Raymond Island. This is surely closely related, and should evidently 
stand as Hylceus giganteus, being wrongly referred to Palceorhiza. To the original 
description of //. fijiensis it should be added that the malar space is large, and the 
mandibles are blunt, tridentate, with the inner tooth very small. 
I cannot find Raymond Island on any map. Raymond in N.S.W. is inland, 
not very far from Newcastle. 
The large metallic species of the group of 11. fijiensis and H. giganteus are 
so distinct from typical Hylceus that they may form a new' subgenus Meghylceus 
with H. giganteus as type. 
Hylaeus albonitens (Cockerell). 
Darwin (G. F. Hill). 
Hylaeus chromaticus (Cockerell). 
Brookfield, Dec. 15, 1926 (H. Hacker). 
Hylaeus perrufus n. sp. 
Female. Length about 5-6 mm. ; rather slender, thorax entirely rather 
dull terra-cotta red, legs clear ferruginous. Head ordinary, black ; mandibles and
