Fig. 19. 
Ipobracon (?) micrarche, sp. n. 
-Phanomeris (?) colenutti, sp. n. (Fig. 20.) 
Anterior wing 4 mm. long; wings clear, stigma fuscous, 
nervures pale brown. Head and thorax fuscous, legs paler ; 
head small ; hind femur about 1 mm. long, only moderately 
stout ; hind tibia+tarsus about 23 mm. long. 
Stigma very large, somewhat bulging ;: marginal cell 
large; terminal section of r. straight; second s.m. large; 
disc. ] not reaching second s.m., its upper side straight, and 
its basal (b. n.) only faintly bulging. 
B.M., I. 9702 (B.). Named after Mr. G. W. Colenutt, 
who has long interested himself in the geology of the Isle 
of Wight.

Phanomeris (?) colenuttt, sp. n. 
This agrees sufficiently with the living Phanomeris 
catenator, Hal., except that the second s.m. is not so long. 
There is also some resemblance to Doryctes, but that has the 
t.-m. more oblique. The first discoidal cell is like that of 
Colastes, not Doryctes, but the stigma and second s.m. are 
more like Doryctes. Oncophenes nearly agrees with the 
fossil, and the shape of disc. 1 is similar (rather more so 
than in Colastes), but 'the shape of the marginal cell differs.
