2 Mr. C. E. Hcllmayr on the 



members, being of very small size with relatively long 

 wings. If separated generically, the name Tyranneutes 

 Scl. & Salv. would become their proper appellation. 



In the synonymy, I have usually quoted only the original 

 references for every name ; but in some cases where two or 

 more recognisable races have been united under one heading 

 by former writers, I have given the principal references. 

 Special attention has been paid to geographical distri- 

 bution, and the range of each species and subspecies is 

 stated in full. I have had the advantage of consulting a 

 large amount of material which, in most cases, illustrates 

 very fully the geographical and individual variation of the 

 various forms. Besides the extensive series at Tring, I have 

 examined those belonging to the Vienna Museum and most 

 of the specimens in Count Berlepsch's collection and in the 

 British Museum. 



I wish to express my sincere thanks to Count Berlepsch, 

 Dr. Hartert, Dr. L. von Lorenz, and the Hon. W. Roth- 

 schild for the help so readily afforded in placing their 

 treasures at my disposal. 



Before proceeding to the detailed account, I give a key to 

 the various forms which I hope will prove useful to students 

 of this pretty group.
