by Blanchard in 1851 is a dark insect with pale wings ; surely not the present 
species. Burr was therefore in error in suggesting oceanica as a synonym of 
erichsoni. We were equally at fault in 1927 in placing pulchripes Bormans in 
synonymy here.

erichsoni. 
The male pygidium agrees in its linguliform type with that of amoenus, 
but this large elongate red-brown species is otherwise very distinct and in 
appearance suggests certain species of the Ancistrogastrinae. 
Nesogaster pulchripes (Bormans in Burr). 
Ivuranda, Queensland, II, 2, 1925, (F. P. Dodd), 1 <j>. McPherson Range, 
National Park, Queensland, XII, 18, 1926, (A. Musgrave), 1 [Austral. Mus.]. 
This is a distinctive species and it is unfortunate that it has been 
twice incorrectly placed in synonymy, under amoenus by Burr in 1911 and 
under erichsoni by Ilebard in 1927. It agrees with the former species in size 
and Labiine appearance, with the latter in colour and unarmed forceps. The 
male pygidium, as it was originally described and also in being broader than 
long, is very different from the linguliform type found in those species. 
Apovostox hilaris (Bormans). 
Kuranda, Queensland, I, 24 and 27, 1925, (F. P. Dodd), I <$, 1 
This insect agrees closely with A. semiflavus (Bormans) in the majority 
of characters used for generic separation, the more quadrate pronotum and 
decidedly longer second caudal tarsal joint suggesting that they may be 
genetically distinct from the genotype, A. pygidiatus (Dubrony). 
The very short female forceps, proximad fitting tightly about the 
rounded pygidium, thence with inner margins straight and attingent to the 
apex further suggest that hilaris may be found to be generically distinguishable 
from either of those species when the Austro-Melanesian genera are better 
understood. 
The male agrees closely with the originally described male except that it 
is considerably larger, the pronotum is suffused with brown except latero- 
cephalad, the wings are dark brown and the feeble proximo-internal projection 
of the forceps is near the base instead of near the apex of the pygidium. These 
differences may well have specific significance, but without more material we 
can not determine this and the great variation shown in the present material 
of MciTdVd feae and McLTdva Wdlldcei indicate that extreme caution must be 
used in considering related Austro-Melanesian species.
