In the-case of the mole-cricket the > digging out of the nests — the

: . Should, however, the:species migrate from place to place and tieval 
on foot, it can probably be kept off any crop which is not previo 
infested, surrounding the cultivated urea with a ditch containing 
"water an nd wide enough not to be jumped over, or, as is successfully 
with boards just so high that they cannot be jumped, and furnished on 
the outside with a tin “ gutter,” z.e., a strip of tin nailed along the top 
so as to project obliquely outwards and downwards. Plants such as 
coffee can be protected by surrounding them when quite young with a 
tin can with the bottom knocked out, , unless, like the ener cricket, the 
insect burrows from below. This method is in use in Flo 
3. LEPIDOPTERA. 
Caterpillars injurious to coffee :—T wo species have been received in 
spirit from Mr. Punch, who writes of the first: “ This ue i (A) 
moth about 3 in. long. I think the moth works at night, as I have 
never seen one free, only such as I have reared in boxes 
The eggs of this insect are oblong and are laid touching side by side 
in a characteristic ribbon-like band. 
The full-grown caterpillar is some two inches long (exclusive of the 
posterior horn). The he is small and notched on the summit, the 
body is cylindrical, rather elongate and tapering behi pi the first three 
segments behind the head are large and inflated, there are four pairs of 
prolegs in the middle of the body. (segs. 6-9 epi “of the head). 
‘The last segment bears a very long, slender backwardly-directed horn, 
Zin. or more in length, and the posterior prolegs (claspers) on it are 
aborted and rudimentary, so that the larva probably sits with its hinder 
portion raised in the air. According to Mr. Punch, the caterpillar is 
uniformly green whéli young, dull, with the swollen portion behind the 
head shining. When older it develops dark-eoloured markings, the 
principal of these consist of a marbled pe meh n; back, anda 
stripe on each side of the two hinder Mimi is déntat ned 
in a long thin cijarsbapéd silk cocoon edin s pe Ar leaf rolled up 
lengthwise. 
^t is not possible to identify this insect, as the moth has not been 
sent. Pessibly it is one of the Notodontidae, or else allied to the true 
silkworm moth, approaching such a genus as 
'The second cater pillar sent is a little smaller, not swollen behind the 
head nor tapering severe the hind claspers are well formed ‘and 
the horn is smaller, sharper, and recurved upwards at the tip. -Itis

side above the spiracles, mA — when alive has not been recorded by 
Mr, Punch, who says of it: “This caterpillar is of similar tastes, and 
‘while very destructive to individual trees is -— found | singly [? on 
scattered so harmful."
