MEMOIRS OF THE QUEENSLAND MUSEUM. 
marks (consisting of narrow bands along orbits, not meeting clypeal yellow, and 
ending about halfway up orbits) ; mandibles yellow, toothed beneath near base ; 
a small triangular yellow spot on cheeks, behind mandibles ; front highly polished, 
convex ; antennae dark, scape black, flagellum very stout and short ; tubercles 
entirely black ; tegulae reddish : legs reddish orange (apparently reddened by 
cyanide), hind tarsi dusky ; wings clear, stigma with dusky margin ; marginal 
cell long ; rudiment of second intercubitus present ; second discoidal complete ; 
lower section of basal nervure strongly arched ; basal nervure to nervulus about 
equal to half lov er section of basal nervure ; recurrent nervure to intercubitus less 
than length of intercubitus. 
Brisbane, Oct. 3, 1916 (H. Hacker). Known by the dark abdominal venter 
and reduced yellow of supraclypeal area. I do not know whether it is a variation 
or a distinct species, but the first supposition seems more probable. 
Turner ella macrostoma n. sp. 
hem ale. Length about 3*5 mm. ; head and thorax shining black ; abdomen 
broad, dark purple, the ventral surface light yellow ; head very large and broad, 
quadrate ; clypeus, triangular supraclypeal area, band-like lateral marks along 
inner orbits going narrowly to top of eyes, and very large patch on lowermost part 
of cheeks, all yellow ; cheeks broad and rounded, shining ; mandibles pale yellowish ; 
antennae pale rufo-tcstaceous beneath ; funicle short and broad, subglobose ; 
flagellum stout and short ; prothorax very small, black, but tubercles margined 
with yellow ; a very minute yellow spot below wings ; vertex, mesothorax. and 
scutellum microscopically reticulate, with extremely minute very sparse punctures ; 
metathorax short ; tegulae rufo-testaceous ; wings hyaline, stigma rather light 
brown ; lower section of basal nervure strongly arched ; basal nervure to nervulus 
about equal to half lower section of basal nervure ; no part of second intercubitus 
developed, but cubital nervure prolonged some distance beyond first intercubitus ; 
recurrent nervure to intercubitus about or nearly equal to length of intercubitus ; 
second discoidal cell complete ; anterior femora stout, dark brown, their tibiae and 
tarsi pellucid honey colour ; middle legs with base yellow, including femora, but 
apex of femora and all beyond, brown : hind legs yellow as far as middle of femora, 
and beyond that brown ; claws simple ; pulvilli very large ; abdomen not pale at 
apex. 
Brisbane, Queensland, Oct. 3, 1916 (H. Hacker). Allied to T. atomaria , but 
easily separated by the very large head, very broad in region of mouth, the yellow 
face-markings, and the higher clypeus, with proportionately smaller supraclypeal 
light area. There is a strong general resemblance to Euryglossina hypochroma Ckll. 
and E. semipurpurea Ckll. 
Turnerella semiflava n. sp. 
Female. Length about 3 mm. ; head and thorax above shining black, but the 
following parts are yellow : clypeus, supraclypeal area, lateral face-marks (broad 
below, and continued as narrow bands along orbits, enclosing short black facial foveae, 
and ending at top of eye as an obtuse or angular projection anterior to and away 
from eye), mandibles, cheeks, sides of thorax (except a rather large black spot on 
lower part posteriorly), as well as legs and under side of abdomen ; above, the 
abdomen is dark, slightly purplish, but more or less distinctly yellow along the sides ; 
the extreme apex is light red. but this may be very distinct or retracted and hardly 
visible. Scape dark ; flagellum very short and stout, bristly, somewhat yellowish 
beneath ; claws simple ; tegulae hyaline with a yellow spot ; wings clear, stigma
