2 THE ENTOMOLOGIST’S RECORD. 
materially increased in the last seventeen years, this work is still 
absolutely indispensable to the student of this group; in it, not only 
are the Orthoptera of Kurope (as politically defined) dealt with, but also 
the species occurring in the neighbouring regions—North Africa, Syria, 
and Asia Minor. 
In working out the rich collections made by Signor Leonardo Fea, 
in Burmah, he gave us, in 1898, a complete [évision and com- 
pendium of our knowledge of the group. This is, perhaps, his 
most important work, and is still considered to be the basis 
of the systematic work that has since been done in the Orthop- 
tera. In fact, in working at any division of the order, the student 
finds this Révision to be indispensable. An important faunistic 
work on Orthoptera collected by Professor Kiikenthal, in the Malay 
Archipelago, appeared last year, and a notable philosophic study, 
Observations on the Colours of Insects, vas published at Leipsig in German 
and English the previous year. In it the author classifies the various 
systems of insect coloration, and, although everyone may not entirely 
agree with the views expressed therein, no thinker could read a more 
suggestive work. 
Among the numerous, smaller essays and faunistic papers, one of the 
most remarkable is Ueber hypertelische Nachahmung bet den Orthop- 
teren (1883), in which the author put forward his well known theory- 
of hypertely which explains, or rather, gives a name, to the lack of 
explanation of phenomena which appear to the author to be mexplicable 
according to the accepted theories of development. 
The Brunner collection of Orthoptera is probably the finest in 
existence ; it includes among other noteworthy things, the great 
majority of Stal’s types of the Phasmodea. The great Swedish ento- 
mologist based all his work on this group upon the specimens in 
Brunner’s collection, bus Brunner himself defies the student to follow 
out Stal’s work m detail without the possession of his types. ‘The fact 
that Brunner is now engaged in completing a monograph of the Phas- 
modea is, therefore, the more interesting. His vast collections are 
centained in a great number of cabinets, and very many species are 
represented also by examples in spirits. 
In the summer of 1898, the writer of this memoir had the honour 
of spending the day in the company of the great entomologist, and 
nothing could have been more interesting than the veteran’s remi- 
niscences of past collecting and past students. He mentioned a strange 
story of a lapsus memoriae. A system of the Gryllodea published by 
him in 1874, enlarged and developed with due acknowledgment by de 
Saussure three years later, was completely forgotten in 1893, for, in his 
great évision (p. 193), he enthusiastically exclaims, ‘‘ As to the Gryll- 
odea, the more I study the monograph published by M. de Saussure, 
the more I am convinced that it is not the system of M. de Saussure, 
but that of the Creator Himself.” After this naive and unstinted 
praise of his own work, as Dr. Krauss has pointed out, he adds three 
genera and nineteen species to ‘‘the system of The Creator.””-—Matcotm
