• Notes on the Ephemerida. 389 
Mineral. &c., p. 385. Ephemerites rupestris is not a 
name given by me, [as I supposed it to have been ; see 
Monograph, p. 40.] Prof. Geinitz sent a photograph to 
me, and I wrote my opinion about the species. I do not 
know whether the figure is exact. 
Page 38. 1864 and 1866.— Scudder. [Mr. S. H. 
Scudder's papers are published in the American Journal 
of Science, xl. 269 — 271 ; and in the Proc. Boston Soc. 
Nat. Hist. (December) ; separate p. 20, pis. 4.] 
Page 39. I am of your opinion concerning the species 
described by Scudder. But I would observe, that, up to 
the present time, I have been unable to obtain access to 
any of the types. . . . The three species desci'ibed 
by Mr. Scudder as Gerephemera simplex, Ephemerites 
gigas and affinis, do not belong to insects at all. If you 
will compare the figures and descriptions of fossil plants 
from the same localities given by Lesquereux in the 4th 
volume of the Geological Survey of Illinois, you will see 
at once that the Ephemerites are only parts of leaves of 
Hymenophyllites or of Neuropteris. I believe that some 
other of the species are similar. 
Page 41. An observation that in copvda the male of 
Ephemera is beneath the female, is to be found in Latr. 
Hist. Nat. ii. 238. 
[In the notes below will be found detailed accounts of 
the entrance into water for oviposition of the female of 
Baetis (Note for p. 119, B. pumilus), and of the casting of 
the subimaginal pellicle of Ccenis (Note for p. 95, C. dimi- 
diata).^
