468 HISTORY OF ENTOMOLOGY. 
In this arrangement of the tribes, as he calls them, of 
Mandibulata, Mr. MacLeay sets out from the Coleoptera, 
which he distributes, according to the supposed typical 
forms of their Jarve, into five minor groups, sufficiently 
noticed ona former occasion*. From this tribe or Order 
he proposes to pass by Atractocerus to the osculant Order 
Strepsiptera, and from thence by Myrmecodes Latr. and 
the Ants to the Hymenoptera. From hence he next pro- 
ceeds to his Trichoptera; in which, as we have seen?, 
he places not only Phryganea L., but also Tenthredo L. 
and Perla Geoffr., making his transit by Sirer L.; form- 
ing an osculant Order which he denominates Bomboptera. 
From this his way to the Neuroptera is by the Perlides, 
with Szalzs Latr. as an osculant Order under the name 
of Megaloptera: he enters by Chauliodes, and leaves it 
by Panorpa or Raphidia by means of Boreus, forming 
also an osculant Order (Raphioptera) for the Orthoptera ; 
which he enters by Phasma, Mantis, &c., and leaves by 
Gryllus Latr., entering the Coleoptera again by the os- 
culant Order Dermaptera formed of Forficula L.: and — 
thus returning to the point from which he set out’. He 
has not, however, made this return of the series into 
itself so clear in each order, excepting in the Ortho- 
ptera, as he has done in the whole Class or Sub-class. 
Thus in the Coleoptera there appears no particular af- 
finity between the Predaceous and Vesicant beetles, his 
first and fifth forms‘, or his Chilopodimorphous Coleo- 
ptera, and his Thysanurimorphous. 
To enter fully into his doctrine of Analogies would 
lead us into a very wide field, and occupy a larger space
