Occasional Notes. 353 
plants in Surinam, and from the resemblance of their 
grub-forms to those obtained from the Essequebo 
plantation, it is most probable that the adult forms are 
identical in the two cases ; though as I have not yet 
been able to obtain adult forms from Essequebo, I cannot 
express any certainty in the matter. The method of 
operation in the two cases is at any rate the same. The 
young shoots or branches are primarily attacked ; these 
wither away, and the death of the tree follows unless 
steps are taken to chop off the infe6led parts. 
When these damaged shoots are examined, it is found 
that the grubs, which are yellowish-brown or whitish, 
thick, maggot-like worms, from one to two inches in 
length, and with extremely strong biting jaws, have 
bored through the central delicate tissue, the point of 
access being generally situated towards the basa! part of 
the shoot, where a scarcely visible gummy exudation 
indicates the punfture or perforation made. The adult 
forms brought for me by Mr. BOSCH-REITZ from Surinam, 
belong to two species, and specimens of each of these 
have been exhibited before the Royal Agricultural and 
Commercial Society and are now exhibited in the Museum. 
They are both Longicorn beetles ; that is, they possess 
long, jointed feelers or antenna? on the head, and 
these are carried like horns. One form, the smaller, 
is black, rather short and broad, and with longitudinal 
lines or stria?, like small ridges ; the other is rather 
long, smooth, nearly black, but abundantly yellow- 
spotted, and provided with lateral spines on the thorax. 
They have been examined for me by Mr. C. O. WATER- 
HOUSE, the Coleopterist of the British Museum of 
Natural History ; and the smaller black specimens belong
