402 Rev. H. Clark’s Descriptions 
this causing to future students! or rather, I would say, how great 
is the risk that some future student, either by accident or indo- 
lence, may ignore part of the contents of such a paper altogether. 
The husbandman who marks out a small portion of unreclaimed 
land, and then brings the whole of that portion under cultivation, 
is doing far better work than he who fearlessly charges at the 
whole sweep of country up to the very horizon; the Jabour of the 
former will bear fruit long after the very name of the latter has 
been forgotten. 
And it is worthy of notice, that that which most permanently 
benefits science is that which also contributes most renown to the 
writer himself. He who has thoroughly mastered one single point 
will certainly stand out among us more clearly than he who has 
ranged over a hundred points and mastered none; to do little, 
and make that little available for others, is far better than to do 
much and to add infinitely to the labours of others. It is not 
the happy possessor of a collection—crowded though it may be 
in types, or most ample in material—whose name will be most 
esteemed by our successors; for collections pass away from hand 
to hand, and leave behind them hardly the name of him to whom 
they have been the care of years: it is not necessarily even the 
irrepressible writer, who has added a hundred papers to our lite- 
rature; it is indeed certain that such a man has been indus- 
trious, but it does not by any means follow that that industry 
has been wisely applied. He rather will be spoken of as ex- 
cellent, who—it may be with small opportunities —it may be with 
less brilliant talent than that of many others—has in his studies 
kept always before him a sense of the vastness of the range of 
Natural Science; a desire to benefit others, rather than to amuse 
himself; and hence a resolution to touch nothing that he cannot 
complete. 
I offer these remarks as a preface to a very unpretending 
paper, with no sort of intention of criticizing any papers pub- 
lished by the Society, except my own; but because 1 desire that 
our literary efforts, which will hereafter give the character to 
ourselves, may not suffer when compared with those of others ; 
and because I am conscious myself of an absolute proneness to the 
failing to which I refer—a tendency to discursiveness in Entomo- 
Jogical work. 
The following descriptions of insects represent part of a very 
interesting little collection of West Australian Phytophaga, which 
has been placed in my hands by Mr. Du Boulay. Mr. Du Boulay’s
