gradual development of these parts, the perfect beetle is produced. These

from his observations that we may distinguish two hinds of 
complete metamorphosis in insects, represented by the types 
Mused and Corethra. In the former the thorax and head of 
the imago ate entirely new formations ; the internal systems of 
organs are also hew formations or undergo a total revolution 
(UmwdUung)\ The pupa possesses Only a latent vitality. In 
the typd Cor Mm j Oh the contrary^ the appendages of the imago 
Sprout from the hypodermic Of the larva. The head and thorax 
are directly derived from the corresponding parts Of the latva \ 
the internal organs are subject to no very important changes^ 
and all the new parts, instead Of being first formed in the pupa, 
show their first traces in the embryo. The life of the pupa is 
not latent^ but is distinguished from that of the larva only by the 
cessation of feeding.

Wilson has communicated to the Entomological Society of 
Ijottdon (Proc. 1864, pp.50, 51) Somo notes oU the entomology 
of South Australia. He gives the numerical proportions of the 
seven principal orders of insects as occurring in that colony as 
follows :~Coleoptera 20, H 5 ^menoptera llj, Lepidoptera 6|, 
Diptera 4|, Phynchota 2, Orthoptera 1> Neuroptera 
The data for orders 2-4 are confessedly imperfect ; probably 
all the numbers are too small in comparison with Coleoptera. 
The number of Coleoptera in collections is estimated at 2000 
species.
