and I am inclined to think that his readiness to helj) on that 

 occasion was the origin of an investigation in comparative 

 morphology, the result of which he published at his own 

 expense, in a short paper, with coloured plates, entitled 

 " The Labium and Sub-mentum in certain Mandibulate 

 Insects." In this paper he has endeavoured to show, by a 

 comparison of the parts in various forms, that the sub-mentum 

 is, in fact, a part of the liead itself and need not be taken into 

 account wlien homologizing tlie parts of tlie labium witli those 

 of the maxillae. Owing to the manner of its publication, this 

 ])aper has, I fear, been almost entirely overlooked, which makes 

 it all the more desirable to call special attention to it here. 

 Prof. Bugnion, witliout in any way referring to it, takes very 

 much the same view of the sub-mentum as Waterhouse, and 

 supports it by other statements of fact ; but as the terminology 

 used by him is not the same, one has to be careful in reading 

 his paper to note exactly what he means by sub-mentum. 

 This name he applies to a part of the labium, using the name 

 basilaire instead for the part figured and described in most 

 of our text-books as the sub-mentum. Which particular 

 part has the right by priority to the name of sub-mentum, 

 I cannot, at the moment, definitely say, but I rather think 

 the name was first made use of in Coleoptera and in the same 

 sense in which it was applied by Waterhouse. 



Arthur Ernest Gibbs was another Fellow of the Society who 

 took a great interest in its work; and as a member of the 

 Council and of the Business Committee, as well as in many 

 other ways, rendered it most valuable service. He was an 

 active member also of the South London Entomological and 

 Natural History Society, of which for a time he was Vice- 

 President. He was a keen student of the Lepidoptera, and in 

 his frequent travels on the Continent, and with the aid of 

 collectors in other parts of the world, got together a very 

 considerable collection. He was -very much interested also in 

 the local museum near his home at St. Albans, which has 

 benefited largely, I believe, through his generosity. Those of 

 us who have had the pleasure of meeting him frequently and 

 of knowing his kindly disposition will miss him greatly, as 

 indeed will this Society as a whole.
