with the Notacantha into a separate division called Entomocera, as 
proposed by Macquart (Dipt. Exot. tom. i. p.89.). The long rostrated 
genus Pangonia forms the connection between the Tabanidz and Bom- 
byliidz, whilst the Acroceridz appear to connect such Anthracide as 
Nemestrina and the Empide ; but this connection is very slight and 
unsatisfactory. The Mydaside intervene between the Asilidz and 
Therevide, to both of which, in general appearance, habits, and tro- 
phi, they are nearly allied, and the Platypezidee and Dolichopide are 
brought into contact with the Athericera, with which the nerves of 
their wings agree. 
The family TaBANID#*, corresponding with the Linnean genus 
Tabanus (fig. 128. 1. Tabanus paganus ¢ ), is distinguished from all
