MEMOIRS OF THE QUEENSLAND MUSEUM. 
punctured ; scape black : flagellum dusky red beneath : mesothorax densely and 
minutely punctured, the punctures not visible under a lens; base of metathorax 
dull and very finely sculptured, not sharply defined behind ; tegulse black ; wings 
hyaline, faintly dusky : stigma large, reddish black : basal nervure meeting nervulus, 
and first recurrent meeting inter cubitus ; legs black, the anterior tibiae partly red 
on inner face, and hind tibiae narrowly light yellow at base ; abdomen moderately 
shining ; venter quite simple. 
Blackheath (type locality), Nov. 23 (G. H. Hardy) ; Stanthorpe, Nov. 10, 1923. 
Five specimens in all. This is not the female of G . amiculina , the female of which 
is known, and I am at a loss to associate it with any other male. It will be easily 
known by the broad- cuneate, lateral face-marks, not produced above. The inter- 
rupted prothoracic band is also characteristic, as Mr. Hacker had noted on a label 
attached to one of the specimens. 
Palseorhiza melliceps Cockerell. 
Two males : Tooloom, N.S.W., Jan. 1926 ( H. . Hacker). The head of the type 
was apparently somewhat discoloured. In the present specimens the light markings 
of the head are bright yellow', except that the sides of clypeus are dark red, this 
colour taking the form of two dagger-shaped marks, the points upward. The mandibles 
are red. The species is easily known by the shining black scutellum and yellow 
axillae. 
Palseorhiza melanura (Cockerell). 
Female : Kuranda, Q., 1919 (A. P. Dodd). 
This belongs to the peculiar group in which the area of metathorax is strongly 
grooved or fluted. It may be regarded as a distinct subgenus : Heterorhiza, type 
P. melanura. 
The known species are separated thus : — 
Abdomen in both sexes honey colour with the apex black . . . . melanura (Ckll.) 
Abdomen with the ground colour dark or black . . . . . . . . . . . . 1. 
1. Thorax with two yellow lines on dorsum : abdomen black or piceous, with (male) 
suffused red band on first Segment, a red suffusion at bases of second and third, 
and a pale-yellow mark on each side of second ; or (female) two red spots on first 
segment, transverse yellow mark on each side of second, and two larger marks 
on third (Mackay, Q.) .. .. denticauda { Ckll.) 
Thorax dorsally with four yellow stripes . . . . . . . . . . . . . . 2. 
2. First abdominal segment with red base and two yellow marks ; segments 2 and 3 each 
with a pair of yellow spots ; antenna*, red-brown (Mackay, Q.) 
longiceps (Friese) (female) 
Abdomen without red ; first segment with a broad V-shaped yellow mark on each side ; 
segments 2 to 4 each with lateral yellow marks ; antenn.n dark, the scape with 
a yellow stripe : wings brown (Murray Island, Torres St.) . . hedleyi Ckll. (male) 
Friese described his species under Prosopis in 1924. (Konowia, vol. 3.) 
The type of P. hedleyi is in the Australian Museum, but there is also a specimen 
in the Queensland Museum. 
Prosopis eximius Smith, from Batchian, Moluccas, is to be called Palceorhiza 
eximia. I examined the type in the Hope Museum at Oxford. It is a male, with 
abdomen appearing broadly truncate at apex, with a spine at each corner, as in
