chiefly along the main trade-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. Tribolium ferrugineum in Ground-nuts. — "In the summer of 1863 a 

 cargo of ground-nuts {Arachis lujpogcea) 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 by countless holes, while the kernels 

 were half eaten up by myriads of larvse 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 opeued the whole interior was often found to be converted into a 

 living conglomerate of larvse, pupae aud imagines of Tribolium, accompanied 

 by the larvse and perfect insects of a Rliizophagus 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 owners being unwilling 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 aud 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. 1872, 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 considei;ed, and still consider, to be an error on Mr. 

 Lewis's part. Aud 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 the mis-statement was pointed out, it would be at once withdrawn.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.
