Mr. it says of it: “ This insect is present to some extent all the year 
round, but especially during February and March; also in August and 
to the same extent. Once in every five or six years they appear in such 
quantities as to be a pest as diligit as the locusts, destroying entire 
farms of suceulent or young plants. Their galleries run down 18 to 24 
inches, and terminate in a cell which wili be found filled with the cut 
leaves and small stems. They are especially destructive to anything like 
coffee planted at even distances. Leaving the ground covered with 
weeds does not save the cultivated plants which they select. A space of 
three acres planted with rubber plants (Manihot Glaziovii) over whieh 
"weeds were allowed to grow, had to be replanted three times this year.” 
In 1891, specimens of this insect received from the African Associa» 
tion, Limited, were reported on to the Royal Gardens by Mr. R. 
McLachlan; F.R. S., as follows :—-
