Diceratoclinea subgen. nov. Subgenotype: Dolichoderus 
scabridus Roger (1826). Other species: beccarii Emery, 
angusticornis Clark, indrapurensis Forel, ypsilon Forel. 
Habitat: Australia and Indonesia. 
D. cornutus Mayr of the Baltic Amber also belongs to 
this subgenus. 
Acanthoclinea subgen. nov. Subgenotype: Dolichoderus 
dorise Emery (1887) . Other species : edentata Forel, exten- 
sispinosa Forel and clarki nom. nov. for D. tristis Clark 
(1930) nec. D. ( Monads ) tristis Mann (1916). 
Habitat: Australia. 
Unfortunately, these subgenera only slightly reduce the 
number of species in Hypoclinea. We may follow Emery in 
distinguishing four geographical groups in this subgenus, 
a holarctic (to which the name Hypoclinea properly belongs, 
since the Eurasian quadripunctatus L. is the subgenotype) 
a Neotropical, an Indomalayan and an Australian, but I 
have not been able to discover in the workers any charac- 
ters that would justify further subgeneric division. This 
may be possible when the sexual phases are better known. 
That the females may possess characters of taxonomic 
value is suggested by Acanthoclinea. Though colonies of 
this subgenus are not uncommon in Eastern Australia, no 
one has ever seen a winged female of any of the species. 
Very recently, however, Clark (Mem. Nat. Mus. Melbourne 
No. 8, 1934, p. 40, pi. 3, fig. 6) has described and figured a 
peculiar ergatoid female from a colony of dorise. It is not 
improbable, therefore, that this is the typical and only form 
of female in the subgenus as it is in Leptomyrmex and sev- 
eral other Australian ant-genera. 
2. The Tribe of Melophorini Forel. 
According to Emery, (Gener. Insect. 1927), this the most 
primitive tribe of Formicine ants comprises only two gen- 
era, Melophorus Lubbock and Notoncus Emery, but it needs 
revision both by subdivision of the old genus Melophorus 
and by addition of two other genera. One of these is Myrm- 
ecorhynchus for which I made a special tribe in 1917. In 
this I was followed by Emery, but I am now convinced that 
Mrymecorhynchus is a Melophorine. Clark has recently
