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. 



Faraneuretns longicortiis 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, antennae 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. longiconiis 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 darker 

 veins and stigma. 



Surface of body shining, finely shagreened. 



Erect hairs absent, except on the clypeus and mandibles, where 

 they are short; antennae and legs clothed with short, appressed pu- 

 bescence. 



Color dark brown. 



Described from a single, very clear specimen (K 7500) in the 

 Klebs Coll. Notwithstanding the different shape of the gaster, I be- 

 lieve that this specimen belongs to the genus Paraneuretus. 



Tribe Dolichoderini Emery. 



Genus Dolicfiocleriis Lund. 



Subgenus Hypoclinea Mayr.

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. doricc Emery, scabridus
