margins obsoletely crenulate. The legs and first four joints of the antenna 
are testaceous; these joints, however, in my specimens are spotted with 
pitchy. ‘The third joint is shorter than the second; whereas the reverse is 
the case in rugosus. In the male characters beneath, this species presents 
considerable differences,—the fifth segment being simple (in rugosus the 
margin bears a conspicuous tubercle), and the seventh has the margin 
simply bisinuate. One male and three female specimens, found by myself, 
near a wet spot in a wood, near Needwood, Staffordshire, January, 1870. It 
is found also in Germany, Austria and France.” 
Prof. Westwood exhibited drawings of a species of Coccus, infesting 
Cypripedium niveum, from Siam. These Cocci were situated on the under 
side of the leaves in groups of four or five, or more. The body of the scale 
was very small, apparently composed of waxy exudation; on the surface 
were six raised radiating white lines, corresponding to the legs of the 
insect, and each of these raised lines was produced into a spine-like process 
extending beyond the margins of the scale; beneath there was an oval 
receptacle, which contained the pupa or perfect insect, but always of the 
male sex. On the under side the mid-rib of the same leaves were 
differently formed, and not stellate scales, which probably were those of the 
female. Some of the first-described scales were altered in form, the raised 
lines being obliterated, and the surface swollen: these he considered to be 
infested with parasites. He proposed to name the insect Coccus stellifer. 
Mr. Stainton remarked that at a recent Meeting of the Scientific 
Committee of the Royal Horticultural Society there were exhibited samples 
of lemons, from Palermo, infested with a Coccus distinct from that which 
ordinarily affects the orange. The rind immediately around the scales 
never acquired the yellow colour, so that the lemons appeared to be 
sprinkled with green spots. The presence of these Cocci was of consider- 
able importance, inasmuch as it rendered the fruit useless for preserving 
purposes. 
Prof. Westwood further exhibited a minute species of Corixa, destructive 
to the ova of fishes in India, received from Mr. H. 8. Thomas, respecting 
which that gentleman made the following remarks :— ; 
“‘Tts habitat is fresh water in the rivers of Canara, though, I dare say, it 
may also be found in other rivers of the Madras Presidency. I observed it 
myself in a still hollow in a rock, where the water was quite clear, and only 
two or three inches in depth. The insects kept tossing the ova up from the 
bottom, and following them closely up to the surface, whence they gradually 
subsided to the bottom by their own weight, the insects apparently adhering 
to the eggs all the time; but the moment they were at the bottom they 
were vigorously tossed up again. I daresay it attacks other spawn also; but 
the ova I saw it engaged with were those of the ‘ Masheer barbas mosal,’ 
commonly called ‘ Masheer,’ the most valuable fish in the Indian rivers.”
