302 Mr. Douglas’s Observations on the 
sreat pleasure in dedicating the species to him who, if 
not its discoverer, first pointed out its differential 
characters. 
Finally, as will have been observed, there are several 
points in the natural history of these very remarkable 
insects that require to be cleared up, and, as I have no 
expectation that I shall ever do this, it is to be hoped 
that some of our younger members who have the time 
and opportunity may be induced to give attention to the 
necessary research. 
Postscripr.—lI have just received the following note 
from Mr. Norman :—‘“‘ Pitlochry, July 8th. I am sure 
you will be glad that I have at length bred the winged male 
of O. cataphracta. After having had the brood bottled 
up since the end of March, and having constantly added 
fresh-caught specimens, I was beginning to despair, but 
to day I found the one I now send to enable you to have 
it figured. I should mention that in the bottle are a few 
O. Normani, but the chances are a hundred to one in 
favour of this one being O. cataphracta.” 
The example may be described as follows :— 
O. cataphracta, male.—Grey-white. Wings (two, an- 
terior) diaphanous, at the base narrow, then immediately 
widening on the lower side, the whole contour being a 
long broad oval; close to the nearly straight anterior 
margin is a strong raised nerve, which ends at about the 
middle of the length; from this, at a little distance from 
the base, furcates a slight nerve directed towards the 
inner margin, but not reaching it, and becoming 
evanescent at about the same distance from the base as 
the strong costal nerve. The antenne slender, filiform, 
about one-third shorter than the wing, the articulation 
obscured. Head, thorax, and abdomen also obscured by 
a white mealy powder; from the end of the abdomen 
projects a divergent pencil of about twelve white hairs, 
which is fully as long as the whole insect. The legs are 
also covered with the same kind of mealy powder, and 
there is a trace of it on the wings. Length, exclusive 
of tail, } line; expanse of wings, 14 line.—J. W. D., 
lith July.
