able absence of some of the most populous groups of 
other parts of the world; thus the TENEBRIONIDZ in 
Australia, though numerous enough, show few of the European, 
American, and African Sub-Families, and are chiefly represented 
by the genera Amarygnus, Adelium, Cephaleus, Heleus, and 
genera allied to them. The genus Zopherosis is one of the 
most remarkable of the Australian forms. . All the Trachelidous 
families of the Heteromera are present, but some, as the 
CANTHARIDE and MELANDRYIDA, very sparingly. 
The TETRAMERA are very numerous. The Ruynco- 
PHARA alone must number in Australia quite 2000 species; the 
groups formed of the genera Leptops, Catasarcus, Amycterus, 
Psalidura, Gonipterus, Rhinaria, and the host of genera 
formed out of them, are among the many characteristic 
Australian forms in this division of the Tetramera. 
The XYLOPHAGA are few in number. 
The LONGICORNIA, on the other hand, abound. About 
550 species have been described, chiefly by Mr. Pascoe; the 
genus Phoracantha among the CERAMBYCIDA, and Symphe- 
letes and Penthea among the Lamiipa#, form the largest 
Australian groups. The PuyropHoGa are extremely numerous 
as a whole, particularly the families CRYPTOCEPHALID and 
CHRYSOMELID#; in the latter family the genus Paropsis, an 
Australian form, numbers over 200 species. The Eupopipz 
are few, but include the noticeable genera Carpophagus and 
Megamerus. The CasstpipH and Hispipm are very few in 
number. The Harricip# and GALERUCID® are fairly 
numerous. The Erotryitp# are limited to about 10 species, 
mostly of the genus Hpiscapha. The Australian Trimerous 
Beetles consist of a few of the APHIDIPHAGA, of the genus 
Epilachna, and a very few of the Fungicola. 
The next Order, the HYMENOPTERA, have not been so 
much attended to as the Coleoptera, so that no estimate can be 
formed of their numbers, but they are undoubtedly very numerous. 
The Cynrpip#, CHALCIDIDE, PRoTOTRUPIDA, and ICHNEU- 
MONIDZ are not only numerous, but they present some very 
remarkable forms. The Formictp2 are still more abundant. 
The Fossorzes are also very numerous, the genus 7'hynnus 
constituting the most strictly Australian group. The APIDz 
are not very numerous. The TENTHRIDINIDZ# are represented 
only by the genera Perga and Nematus. 
The Order ORTHOPTERA is, if not so numerous as the 
other Orders, quite as remarkable. BuLatTTipm are numerous ; 
the Mantip# and Puasmatipa# of Australia are remarkable 
for their size and beauty. The GrYLLID# contain species of 
very. singular forms, and the AcrRIDIIDm include some very 
destructive species of dipoda or Locusts. The Eupiex- 
OPTERA (Earwigs) are also numerous.
