tionship with the Bphemeridce. Then follows an essay on the structure 
of the wings in that family. After this are detailed descriptions of the 
species, viz., PlatepJiemera antiqua^ p. 7, pi. i. figs. 5, 9 & 10 (with a reply 
to Eaton’s criticisms) ; Gerepheinera simplex, p. 12, pi. i. figs. 8 & 8a, con- 
sidered as representing a distinct group, for which the term Atocina is 
proposed ; Homothethus fossilis, p. 17, pi. i. figs. 1 & 2, considered a con- 
necting link between Neuroptera proper and Pseudo- Neuroptera, and as 
the type of a family termed Jlomoihetidce ; Dyscrltus vetustus, p. 20, pi. i. 
fig. 4 ; Llthentomum Tiarti, p. 22, pi. i. fig. 3, not to be placed in any exist- 
ing group, and the group Cronlcosialina is invented for its accommoda- 
tion ; Xenoneura antiquorum, p. 24, pi. i. figs. 5-7, also not to be placed in 
any recent group, and the family Xenoneuridce is proposed for it. In his 
general summary, the author states, amongst other things, that the general 
type of wing-structure has existed from the earliest times; all the Devonian 
insects were Heterometahola ; nearly all are synthetic types, often more 
complicated than the more recent carboniferous insects ; all were of great 
size and probably aquatic in their early stages, &c., &c. The memoir 
ends by a note on the geological relations of the insects, from the pen of 
Principal Dawson, in which the correlation of plant-remains with the 
various insects is examined in connection with the different strata.

pp. 1-24. 
An attempt to identify species of insects described by Strom between 
1765 and 1781, mostly in “ Trondhiemske Selskab Skrift.er.” Some 
Neuroptera are referred to; but only those cases in which priority is 
apparently involved will be alluded to here. 
Trichoptera. 
Hagen, H. A. Ueber die Bestimmung der von Linn^ beschriebenen 
Gattung Phryganea. S. E. Z. xli. pp. 97-106. 
The author critically examines the published evidence concerning the 
identification of the Linnaean species of Trichoptera, with especial refer- 
ence to Wallengren’s paper and McLachlan’s remarks thereon [cf. Zool. 
Bee. xvi. Ins. p. 203]. He objects to the whole of Wallengren’s proposed 
changes, and, on the whole, leaves the subject much as in the generally - 
accepted condition. A suggestion to the effect that P . Jlavilatera, L., 
= Neuronia lapponica, Hag., is the chief novel feature. (On this point, 
compare Kolbe, S. E. Z. xli. p. 351.) Too much importance is attached 
to information received, second-hand, many years ago, from the then 
Librarian (not “ Secretary ”) of the Linnaean Society.
