chiefly along the main tra:de-route, and become acclimatised along their 
whole course, Basle being one of the chief markets where Central Europe 
stores and disposes of the purchases derived from Mediterranean and 
Atlantic ports." 
2. TriboUum ferntgineum in Ground-nuts. — " In the summer of 1863 a 
cargo of ground-nuts {Arachis hypogma) arrived in the port of London direct 
from Sierra Leone. On arrival the usual samples were drawn, when it 
turned out that the husks were riddled bj countless holes, while the kernels 
were half eaten up by myriads of larvae and imagines of Tribolium ferru- 
gineum. So completely had they done their noisome work that in the 
numerous samples examined scarcely an intact kernel could be found. If 
a nut was opened the whole interior was often found to be converted into a 
living conglomerate of larvae, pupae and imagines of Tribolium, accompanied 
by the larvae and perfect insects of a Rhizophagus preying on the former, 
the whole mass being wrapped up in a layer of cast-skins and excrement. 
As no purchaser could be found, owing to the deplorable state of the cargo, 
the work of destruction continued through the months of August, September 
and October, the ownei's being uiiwilling to take a considerably lower price 
than had been calculated upon. A fresh proof how the marketable value of 
an article can become reduced through delay and ignorance on the part of 
its owner." 
Mr. Dunning read the following "Further Note on Atropos pulsatoria, 
with reference to Dr. Hagen and Mr. W. A. Lewis." 
" There is on the table this evening an abstract of Mr. Lewis's paper, 
"On Dr. Hagen's treatment of Atropos pulsatoria and Termes fatidicum" 
(Proc. Ent. Soc, ]872, p. xl.), in answer to some remarks I made on the 
4th November, 1872. If the Society is not weary of the subject, I should 
like to say a few words, and will be as brief as possible. 
" Sympathising with Mr. Lewis in what I conceive to be the main pur- 
pose of his ' Discussion of the Law of Priority,' but feeling that a good 
cause ought not to be supported by a misrepresentation of facts, I ventured 
to point out what I considered, and still consider, to be an error on Mr. 
Lewis's part. And I certainly was sanguine enough to expect that when 
the mis-statement was pointed out, it would be at once withdrawn. 
" However, Mr. Lewis does not see the matter in this light, and contends 
that he has made no error of the kind I supposed. He says that I have 
written in the language of apology only the same things which he has 
written in the language of fault-finding ; that I have concluded he was 
under some misconception from failing to understand that he considers 
worthy of reprobation what I pass by as nothing; that I have come forward 
to justify Dr. Hagen for having published a Synopsis of the British Psocidse 
without an investigation of the species.
