honor of Mr. F. P. Dodd, the well-known observer and collector of 
Queensland insects. I was so fortunate as to discover the females 
of mjébergi and doddi and the larva of the former species. The female 
Onychomyrmex is of such an unusual type that it seems advisable to 
revise the genus in such a way that some of my Australian friends may 
be able to recognize all the known species at a glance and to make 
additions to our knowledge concerning their habits. 
Unfortunately the male Onychomyrmex is still unknown and will 
have to be found before the precise status of the genus in the sub- 
family Ponerinae can be ascertained. Forel does, indeed, describe a 
male ponerine taken by Mjéberg as that of 0. hedleyz, but he says that 
he does this “with a very great interrogation point.” He has, in fact, 
no evidence that the specimen is an Onychomyrmex, except the very 
inconclusive fact that it was taken in the same locality (Malanda, 
Queensland) as the worker of hedleyi. I deem it advisable, therefore, 
to assume that the male is unknown till it is actually taken in nests 
with the workers. Such observations as I was able to make on the 
habits of the three species of Onychomyrmex are recorded below in 
connection with the taxonomic descriptions. So far as at present 
known all the species of the genus are confined to Queensland, and all 
live in red rotten logs in the tropical rain-forest (“scrub’’).! -

Worker. Small, slender, monomorphic. Mandibles rather long, 
narrow at the base, broadest in the middle, with long, curved, acute 
tips, their inner borders armed with a number of unequal teeth, some 
of which, near the middle of the series, are directed backward. Both 
the maxillary and labial palpi very short, 2-jointed. Clypeus very 
short, abrupt, with rounded, entire anterior border beset with a regular 
row of minute teeth. Frontal carinae small, prominent, closely 
approximated, enlarged and dilated anteriorly, separated by a very 
narrow groove. Frontal groove lacking. Eyes'very small, consisting 
of about 6 or 8 ommatidia, situated behind the middle of the head. 
1Kmery believed that the Anomma erratica of Frederick Smith from New Guinea 
might be an Onychomyrmex, but the description mentions none of the distinctive 
characters of this genus and was, perhaps, drawn from an Aenictus.
