WASPS OF THE GEE US CEJSCMMS IN THE QUEENSLAND MUSEUM. 3o 
behind ; anterior and middle tarsi pale, hind tarsi dark fuscous ; petiole 
broader than long, its apical margin red ; second tergite black, obscurely 
reddish at base ; third dull red, somewhat blackened in middle, with an apical 
interrupted pale yellow band ; fourth black ; fifth black, with a broad but 
obscure pale reddish band ; pygidial plate broad, dark red, blackened apically. 
Pleura and venter simple. 
Darra, Brisbane, Dec. 14, 1915 (77. Hacker). In Turner’s table it falls 
near C. opposita, but it is very distinct by the structure of the clypeus and 
other characters. C. unispinosa Turner, from Darra, has a name which would 
have been appropriate for this species, but it is quite a different insect. Mr. 
Hacker had labelled this as a new species. 
Gerceris brisbanensis n. sp. 
Female. Length hardly 6-5 mm. ; rather slender but with broad head, 
strongly punctured, black with pale ornaments ; hair scanty and white,, 
appressed and silvery on clypeus ; mandibles pale yellow with long black apex ; 
face pale yellow, with a rather narrow black band from each antenna down to 
clypeus, leaving an elevated yellow frontal carina, broadened below ; lateral 
face-marks ending in an obtusely subangular manner halfway up front ; a 
broad pale-yellow stripe behind eyes, the upper part divided, separating the 
usual postocular spot ; a gently curved yellow 7 band across top of head, 
interrupted in middle ; margin of middle lobe of clypeus black, but it is 
overhung by a very broad short lamina, broadly and rather shallow'ly emargi- 
nate, with a dark rounded tubercle at each side, and anterolateral to these, 
on the true margin, is a shiny dark tubercle ; scape yellow 7 in front and 
behind, a little dark at apex ; flagellum long, dark brown above, testaceous 
below 7 ; prothorax and mesothorax entirely black, or prothorax may have 
two large yellow spots ; scutellum and postscutellum each with a yellow 
band, but that on scutellum may be interrupted ; metathorax with a pair of 
fusiform yellow marks (a little stained with red), converging below 7 ; area of 
metathorax triangular, black, finely irregularly plicatulate all over ; mesopleura 
simple ; tegulse clear yellow ; wings hyaline, dusky in marginal cell and at 
apex ; stigma light rufous ; second cubital cell very broad, receiving recurrent 
nervure before the middle ; legs light reddish -testaceous, anterior ones 
blackened at base, and their femora darkened above ; petiole much longer 
than broad, pale dull reddish, black at base ; second tergite light yellow, 
suffused with red ; third black, narrowly obscure red apically, and broadly 
so at sides ; fourth dull pale yellow, black at base ; fifth brown or pale 
yellowish ; apical plate broad, very dark reddish or partly yellowish. 
Two females, Darra, Brisbane, Dec. 14, 1915 (//. Hacker). An insignificant 
looking but distinct species, resembling G. venusta, but the structure of the 
clypeus is different. 
Cereeris goodwini n. sp. 
Female. Length about 8-3 mm. ; black, with thin white hair, conspicuous 
at sides of metathorax and on cheeks, long on sides of petiole and basal part
