had arisen as the result of the changes consequent on sun-scalds to gain access 
to the pulp of the fruit, and enlarged them whilst exercising their feeding 
habit, was very evident. 
The berries that were already partially deprived of their contents also 
harboured small flattish beetles, belonging to the genus Brachypeplus [Fam. 
Nitidularide|—insects that in Queensland attack fruit manifesting the changes 
attendant on incipient decay. Moreover, on one of the berries of the bunch of 
grapes illustrated, it was remarked that the surface was densely occupied by 
small black elevations, the pustules of a tubercularia-like fungus, apparently 
Strumella vitis, McAlp. This in the state represented occurs as a saprophyte. 
2. Dematium Funaus Ror (Plate XVII.)—This form of Fruit Rot differs 
from the preceding (that designated Sun-Scald) in the fact that the berries are 
never fissured, their contents shrinking instead of increasing in volume. It 
may, moreover, occur on any part of an affected bunch and not on its exposed 
face only; and, though usually developed to a less degree, may ultimately 
involve the whole of the berries that constitute it. It is met with upon the 
grape fruit when this is but two-thirds grown, and at any subsequent period: 
and the phenomena to which it gives rise vary, in their main features, in 
correspondence with this early or late development. The Muscat varieties of 
Vitis vinifera are especially susceptible to its attacks; but by no means are 
exclusively its victims. 
An affected bunch of grapes (variety unascertainable), on which the berries 
were about two-thirds grown, derived—early in December—from a district near 
Brisbane, presented the following characters. The fruit was damaged in a very 
uneven manner. Not only did individual grapes arising from the same branchlet 
of those composing the bunch vary in the dawree to which they exhibited its 
presence, but one might be subject to the rot, whereas the other appeared 
quite healthy. The diseased berries contrasted with those surrounding them, 
and which were green and intact, in exhibiting a reddish-brown colouration 
(that of new leather), and had their surface puckered with conspicuous folds, 
indicating a shrinkage of their contents. Those berries in which the affection 
had been longest manifested were already of a deep chocolate hue, and were 
dried up to a greater or less extent with much wrinkling. 
In an instance of its occurrence in one of the Muscat grapes grown on the 
Darling Downs, and whose fruit more nearly approached ripeness, some of the 
berries exhibited like appearances, but in the case of others the disease only 
extended to one face. Here a large brownish or purplish-brown depression 
occurred with marginal circumferential wrinkles; suggestive of the effects of 
pressure from the finger-tip on a yielding surface. 
Examples of its presence in connection with a variety of grape with 
purple fruit, named Aramon, derived from the Darling Downs, also, during the 
first week in February, illustrated the effects on fruit that was fully ripe. In 
this case in some instances the entire fruitage was affected, in others the 
berries on one or two of the branches at the “shoulder” of the bunch were 
still free from attack. In the majority of instances the extremities of the 
bunches manifested the effects of rot'in greater degree than other parts, and 
appeared to have been earliest infected. 
The natural tint of the fruit, generally speaking, masked all colouration 
changes. Berries most recently affected were soft and yielding to the touch, 
their contents haying apparently lost their normal consistency. This might be 
especially pronounced on one face, or the entire berry might exhibit these 
characteristics. At a later stage, the berry had the appearance of a bag of 
fluid with foldings of the surface immediately beyond the termination of the 
pedicel to which it was attached. With still further advance of the disease the 
grape had its surface fully occupied with wrinkles, and was evidently in process 
of deans until ultimately small dried-up raisin-coloured objects occurred in 
the place of luscious fruit. Concurrently with the development of these
