known species of Aneuretus. They show that the tribe Aneuretini 
was long ago represented by several distinct and peculiar genera, of 
which only one has survived the Tertiary. 
Faraneuretus longicornis sp. nov. 
Male. Length nearly 7 mm. 
Differing from the male of the preceding species in the following 
characters: Body smaller, eyes larger, more convex and more nearly 
circular, palpi longer, antennse much longer, being as long as the body 
(7 mm). (Those of P. tornquisti are about 7 mm with a body length 
of about 10 mm.) The petiolar node of P. longicornis is proportionally 
longer through its base and the gaster is much shorter and elliptical, 
and the genitalia are much more retracted so that their form cannot 
be determined. The wings have the same venation as in P. tornquisti , 
but their membranes are uniformly brown, with somewhat dark er 
veins and stigma. 
Surface of body shining, finely shagreened. 
Erect hairs absent, except on the clypeus and mandibles, where 
they are short; antennse and legs clothed with short, appressed pu- 
bescence. 
Color dark brown. 
Described from a single, very clear specimen (K 7500) in the 
Klebs Coli. Notwithstanding the different shape of the gaster, I be- 
lieve that this specimen belongs to the genus Faraneuretus.

This species, which is known only from the worker phase, and 
is very easily recognized by its huge divergent epinotal spines, has 
been adequately described and figured by Mayr. At first sight it 
looks like a Polyrhachis, as Mayr remarks, but the structure of the 
head at once shows it to be a true Dolichoderus, allied to some of 
the recent Australian forms, notably to D. dorice Emery, scabridus
