ness of his views. Although of retiring demeanour, and comparatively little 

 known until quite recently in the Entomological world, he very quickly made 

 his mark among our London Societies, and his presence will be missed by all, 

 as well as his critical remarks, on the markings and variations of the Rhopalo- 

 cera, of which the Lycxnidse were his especial favovirites.

Mr. Robert Newstead, the retiring Vice-President, delivered the Address^ 

 which was entitled, " The Taxonomic value of the Genital Armature in the 

 Tsetse Flies (Genus Glossina) . He stated that he had made a careful examina- 

 tion of all the hitherto described species of the genus Glossina which had not 

 only revealed some very striking morphological characters, but had led to the 

 discovery of three hitherto undescribed species : Glossina sxibmorsitans, Newst., 

 G. brevipalpis, Newst., and G. fuscipes, Newst., and also to the re-establishment 

 of Bigot's G. grossa. The scheme of classification adopted was based entirely 

 upon the taxonomic characters of the male armature which are the true and 

 almost only natural anatomical elements that can at present be found in these 

 insects. He had found that the species fall into three very striking and 

 distinct groups, each being separated by very trenchant characters. These are : 

 Group I (the Fusca Group). This division includes the four largest species 

 of the genus : G. fusca, Walker, and G. grossa, Bigot, which have a Western dis- 

 tribution ; G. longipennis, Corti, and G. brevipalpis, Newst., occvu'ring chiefly on 

 the Eastern side of the Continent (Africa) . In all of these species the claspers 

 are quite free, there being no membrane stretching between them ; the distal 

 extremities of these appendages have either a single large and bluntly pointed 

 tooth-like extension or they are bluntly bidentate ; the harpes in all cases 

 being markedly different in their morphological characters. Grovip II (the 

 Palpalis Group). To this division belong the following species: G. palpalis, 

 Rob.-Desv., G. tachinoides, Westwood, G. fuscipes, Newst., and G. pallicera, 

 Bigot. In all of these species the claspers of the males are connected by a thin 

 and finely spinose membrane which is deeply divided medially, but in all cases
