6. APROSTOCETUS OBSCURUS new species. 
Female: — Length, 1.10 mm. 
Yellowish brown, the wings hyaline, the pronotum, cephalic part of scutum and its median 
grooved line, inner sides of parapsides, propodeum, postscutellum and three cross-stripes on 
abdomen beginning just distad of middle, dusky blackish; antenna except scape and lower part 
of -pedicel (white or pallid), vertex and oral region, dusky. Mandibles tridentate, scutellum 
with four grooves. Pedicel slightly shorter than first funicle joint, the next two joints longest 
of the flagellum, subequal; club terminating in a long seta, the flagellum cylindrical. First 
funicle joint over twice longer than wide. 
Male : — Not known. 
Described from one female captured by sweeping in jungle, July 26, 1913. 
Habitat: Meerawa (Cairns), Queensland. 
Type: No. Hy 1778, Queensland Museum, the above specimen on a slide, with type head 
of Quadrastichus aeneus Girault. 
7. APROSTOCETUS NIGRITHORAX new species. 
Female: — Length, 1.15 mm. 
Black, the wings hyaline, the abdomen brownish, lemon yellow at base, the legs lemon 
yellow (coxa? not seen) ; inner margins of parapside yellow; antennae dusky yellowish, the funicle 
joints all subquadrate, the first a little the longest, somewhat shorter than the pedicel. 
Male : — Not known. 
Described from one female captured by sweeping young eucalypts, April 20, 1913 
(H. Hacker). 
Habitat: Brisbane, Queensland. 
Type: No. Hyl779, Queensland Museum, the above specimen on a tag, an antenna 
on a slide. 
8. APROSTOCETUS SEXGUTTATUS new species. 
Female: — Length, 0.80 mm. 
Golden yellow and like flavus but on dorsal abdomen along proximal half there is a line 
of three rather large spots down each side; the scutum is not noticeably embrowned and there 
is a fuscous dot on pronotum at latero-caudal angle. Funicle joints subquadrate, the third a 
little longer, all shorter than the pedicel which is not elongate, only of moderate length. Club 
w r ith a minute nipple, its middle joint subtransverse. 
Male : — Not known. 
From one female captured by sweeping in forest, banks of Cape River, December 26, 1913. 
Habitat: Capeville (Pentland), Queensland. 
Type: No. Hy 1780, Queensland Museum, the above specimen on a slide. I have 
compared this species with the type of Epentastichus which it so closely resembles; the antennal 
differences are easily seen, since here the pedicel is not elongate but usual in length. It is 
necessary that more material be seen, however, before it can be stated positively that the club 
is 3-jointed, plainly indicated in the above specimen of sexguttatus.
