‘Another destructive insect is the Sawfly of the 
Rose (Selandria Ethiops). Durmg the month of 
June, the leaves of the Rose trees are often found 
assuming a withered brown colour, as if scorched 
by fire. The cause of this may be traced, by the 
aid of a microscope, to the destructive effects of this 
insect. The upper circle of the leaf will be found 
nearly eaten away, while the under-side remains 
perfectly entire. A closer examination will show 
the enemy itself, in colour so nearly resembling the 
foliage that its detection by the naked eye is almost 
impossible. In its larva state it is nearly half-an- 
inch long, of a cylindrical form, with a dark line 
down the middle of the back. ‘The head is orange 
colour, with a small black spot on each side. 
The larve change their skins several times before 
arriving at their full size, and then descend into 
the earth, where they form elliptical shells, highly 
polished on the inside ; in these they pass the 
winter, and eventually become transformed, first 
into the pupa state, and afterwards, towards spring, 
into perfect insects. Syringing the Roses with 
water in which hot lime and soot have been steeped, 
is one of the best remedies for the suppression of all 
tender-skinned insects on Roses and other plants.” 
The Rose Aphis (Aphis Rose) is a great pest 
amongst Roses, and especially in situations where 
air cannot circulate freely amongst the plants ; in 
such confined places much difficulty is often exper- 
ienced in keeping these troublesome insects under, 
and generally the weakest and most delicate sorts 
are those worst attacked. Numerous recipes are
