The large tropical forms, with fuliginous or maculated 
wings, are wholly absent from the Collection. There is no 
particular resemblance in the Gurnet Bay fossils to the 
Miocene species from Florissant. Déospilus repertus, Brues, 
from Florissant, is easily separated from D. acourti by the 
second s.m. broadened below. Oliyoneuroides, Brues, 1s 
unlike any of our insects. 
(Fig. 12.) 
Head and thorax black, the thorax very small, its width 
hardly more than halfa mm.; anterior wing about 2°4 mm. 
long, hyaline, faintly dusky, with pale fuscous stigma and 
nervures. 
Stigma very large; r.2 (beyond second s.m.) straight ;
