Oligocene at Gurnet Bay (Brodie). 



Holotype, (a. 14), I. 9198, in Brit. Mus. (PI. V. fig. 6). 



Dolichoderus gurnetensis, sp. n. 



In the unique specimen the head is separated from the body, 

 but lies near it, and parts of a fore and hind wing are present. 

 The thorax, scale, and gaster, two perfect legs, and parts of 

 others can be seen. 



The scale is large and high, the second cubital cell long, 

 and the discoidal cell, which touches it, oblong. The base of 

 the radial cell is slanting, not forming a straight line with 

 the apex of the second cubital cell. The insect measures 

 (with head) 5*5 mm. long; discoidal cell, long "7 mm.; 

 second cubital cell, long 1 mm. ; first cubital on discoidal 

 •5 mm. ; basalis on first cubital '3 mm. ; second cubital cell 

 at apex *5 mm. 



Oligocene at Gurnet Bay (Brodie). 



Holotype, (a. 17), I. 9755, in Brit. Mus. (PI. V. fig. 7).
