Chrysops vectensis, sp. 1. 
H. 46. Branchiopoda bed. The anal cell is as in 
C. sepulcralis, Fab. The small size indicates Chrysops rather 
than Zabanus, and the somewhat contracted fourth posterior 
cell agrees best with the Pangonine. 
LEPIDOPTERA. 
GurnettIa, gen. nov. (Cosside.) 
Broad-winged moths of fair size; anterior wing with 
areole, chorda, and stem of media well developed, but the 
V-like fork of media below end of cell is absent through the 
lack of its upper portion ; the areole is long, and has the 
appearance of being divided. off from the cell, as in Zeuzera, 
not mainly beyond it, as in Cossus; , runs so nearly 
parallel with J, that its separation must be far basad (not 
near the areole as in Jefferis Turner’s hypothetical Proto- 
cossid) ; R; arises below the areole, and is very close to M,, 
which is widely separated from M,; the separation of M, is 
essentially as in Cossus, and not at all as in Zeuzera; Cuz is 
very distinctly curved. The membrane is covered with fine 
transverse striz (11 or 12 in a mm.), on which the scales 
were set.
