3. EPIPERILAMPUS SIGNIFICATUS new species. 
Female: — Length, 2.25 mm. 
The same as xanthocephalus hut nearly the entire body is dark purplish blue except 
head, sides of scutellum at the middle, front tibiae, scajDe, sides of scutum and its caudal third 
and the marking on the abdomen which are orange yellow; also the postmarginal vein is a little 
shorter and the first funicle joint subequal to joints 2 and 3 which in both species are somewhat 
wider than long (funicle 1 in xanlhocephalus is somewhat longer than wide, plainly longer 
than the next two joints). The wings are somewhat clearer. 
Male : — What appears to be the male is wholly dark purplish except cephalic tibne, the 
venation not pale brown but fuscous. Antennae filiform, 13-jointed, the club 3-jointed but not 
widened as in the female, the two ring-joints shorter, distinct, the funicle joints large,, 
all somewhat longer than wide, the first much longer than wide, longest, much longer than the 
globular pedicel which is somewhat smaller than the distal funicle joint; scape wholly blue, 
short. Club joints somewhat shorter than the distal funicle joint. Abdomen depressed. A 
little smaller than the female, the postmarginal vein a little longer. 
Described from a single pair mounted on a card from the collections of the Queensland 
Museum with a female of xanthocephalus and labelled “Gall No. 6. Brisbane. H. Hacker.. 
19.7.1911.” 
Habitat ; Brisbane, Queensland. 
Type: No. Hy 1951, Queensland Museum, the above pair on a tag, female antennas and a 
male antenna on a slide (together -with an antenna of a female xanthocephalus ) . 
I have re-examined the types of xanthocephalus for the third or fourth time. The axillse- 
have a small bluish spot near centre of cephalic margin. 
4. EPIPERILAMPUS DILUTIVENTRIS new species. * 
Female: — Length, 2.40 mm. 
Like xanlhocephalus but the conspicuous orange yellowish, crescentic, thick cross-marking 
in centre of base of distal half of abdomen entirely wanting and the postmarginal vein is a 
little longer than the stigmal; also the scutellum is washed with more or less bluish centrally,, 
the parapsides unmarked, the wings hyaline except for the usual stain from near apex of 
submarginal vein which is widely interrupted caudad. First two pairs of legs yellowish. The 
antenna differs in that only the third joint appears like a ring-joint, the next two or three- 
much wider than long, the ninth joint large, subquadrate, much the largest (longest and 
widest) of the funicle (in xanthocephalus, 1 of the funicle is the longest, 6 the shortest and 
widest, not counting the two ring-joints of which the second is the wider)* The ring 
joint is only a little over half the width of the joint following it. The scape is stouter. 
(Club not wholly seen.) 
Male : — Not known. 
Described from one female in the collections of the Queensland Museum, mounted on a 
card labelled l( Bred from gall No. 14.” 
Habitat: Queensland (? Brisbane). 
Type: No. Hy 1952, Queensland Museum, the above specimen and a slide bearing two- 
broken antennae. 
* The second species of Melanosomella Girault which belongs here. Ccelocybella Girault belongs here;
