458 Mr. T. D. A. Cockerell on Fossil Arthropods 
Dicranomyia excavata, sp.n. (Fig. 7.) 
Wing about 6°5 mm. long ; hyaline, with brownish veins, 
and a cloud at the marginal cross-vein, exactly as in 
D. simulans, Walker. It differs from simulans by having the 
preefurea strongly curved at base, and in this respect agrees 
with D. whartoni, Needham. 
Fig. 7. 
Dicranomyia excavata, sp. n. 
I. 8884 (Brodie collection). I collected the living 
D. chorea, Mg. (det. F. W. Edwards), at. Yarmouth, I. of 
Wight. It is remarkably similar to D. excavata, but the 
spot in the marginal cell is very faint. 
Epiphragma spiloptera, sp.n. (Fig. 8.) 
Wing about 11°5 mm. long (not quite 11 mm. preserved, 
the apex missing), quite broad, pale reddish grey, with 
Fuscous spots and clouds as shown in figure ; first marginal 
cell about 4°5 mm. long, slender, obtuse at base, squarely 
Fig. 8. 
LEpiphragma spiloptera, sp. 0. 
but narrowly truncate at apex; discal cell with its upper 
apical corner a right angle, its outer side vertical, but its 
inner side (on first basal) distinctly oblique, its side on 
second basal about three-fifths that on first basal. 
1.9015 (Brodie collection). Iam indebted to Mr. Edwards 
for the suggestion that this may be referable to Epiphragma.
