Some changes in nomenclature are also made, original synonymy is given, and 
corrections of errors are noted (apropos of which it may be observed that the un- 
noticed errata of the work are somewhat numerous). 
After this, the author gives descriptions of species observed since the com- 
mencement of his work, the following being new: Nephanes meridionalis, S. Ame- 
rica; Trichopteryx Hornti, N. America. 
37 species are recorded as unknown to Mr. Matthews, and 28 others as indi- 
cated only by name, with no descriptions ; and the work concludes with an account 
of the 58 anatomical preparations from which its figures and descriptions were 
taken. 
The first 19 plates, consisting of outline engravings from the author’s drawings 
of general points of structure, &c., and of the imago, with highly magnified anato- 
mical details, of the typical species of each genus, appear to be as near perfection, 
for accuracy, as could be attained ; but the remainder, on which are figured limbless 
half-bodies, especially intended to exhibit superficial sculpture, seem scarcely so 
satisfactory ; as, however accurate their outline, their want of facies is most likely 
to cause their recognition anything but easy to all except those who have conside- 
rable knowledge of the group. ‘The medium of lithography, moreover, being 
hardly adequate to represent minute characters of surface, these plates will not, 
as figures, bear comparison with Sturm’s beautiful engravings in Gillmeister’s 
work above mentioned ; but it would seem that the beauty of these latter is their 
only claim to attention. 
The eccentricities of Astatopteryx and the Tachyporiform Limulodes, with its 
wonderful mesosternum, will, it is to be hoped, have the effect of inciting a more 
general study of this somewhat neglected group. 
Obituary. 
Dr. Franz Xaver Fieber—We learn from Deyrolle’s ‘ Petites Nouvelles Entomo- 
logiques’ of the 15th March, that Dr. Fieber died at Chrudim, in Bohemia, on the 
23rd February, aged 65. European Hemipterology has in him sustained a loss 
that will not soon be replaced; for probably no one has done more, by pen and 
pencil, to advance the study of European Hemiptera. We believe that, for many 
years, he was occupied on a general work on the Homoptera, and we fully second 
Dr. Puton’s remark that it is much to be desired that some editor, capable of the
