AN INTRODUCTION TO THE STUDY OF 

 BRITISH DIPTERA. 



ADDITIONAL NOTE. 



THE accompanying twelve diagrams of wings of 

 Diptera, having, unfortunately, been omitted 

 from my recent paper on British Diptera in Science- 

 Gossip, I take the opportunity of correcting two 

 errors in previous diagrams. 



In Fig. 147, {Liinnobki, Mg.,) the cross vein 



forming the basal side of the discal cell should be 

 continued in a straight line till it meets the next vein 

 (the postical). 



Fig. 149 is wrongly named Rhyphus. This genus 

 was correctly illustrated before, on page 37 (Fig. 26), 

 and Fig. 149 is a diagram of the wing of Tipula, L. 



As the diagrams of wings have been scattered 

 through the article without regard to the letter- 

 press relating to the families they represented, it may 

 be as well to give a full list of them in their proper 

 order.

I hope during the winter to be able to extend my 

 notes for beginners, and to write a lengthy supple- 

 ment to my previous article ; this supplement con- 

 sisting principally of analytical tables of genera. I 

 shall also add notes on parasitic Diptera, and the 

 geological antiquity of this order.
