AFFINITY TO LYPEEOSIA AND STOMOXYS. 59 



MusciN^, of the family Muscid^e, and that its neai-est existing 

 allies are found in the genera Stomoxys, Hsematohia, Lyperosia 

 and Beccarimyia ; but that it is a highly specialised form, 

 exhibiting several unique structural features, in addition to a 

 very peculiar mode of repi-oduction. In some respects Glosslna 

 approaches most nearly to Lyperosia, while as regards other 

 structural characters it comes nearer to Stomoxys. If, however, 

 we rely upon the character and mutual relations of the proboscis 

 and palpi, the Tsetse-flies are certainly more closely allied to 

 Lyperosia than to any other genus at present known.
