UNDESCRIBED SPECIES IN THE OSTEN SACKEN 



COLLECTION OF NEW ZEALAND 



CRANE-FLIES 



(Diptcra, Tipulida) 

 By CHARLES P. ALEXANDER 



Subsequent to his return to Europe and the selection of his 

 final abode in Heidelberg in 1877, Baron Osten Sacken 

 amassed a very considerable collection of the crane-flies of 

 New Zealand, chiefly through the efforts of Prof. George V. 

 Hudson. From these rich collections only a very few of the 

 new species were described by Osten Sacken, but in the inter- 

 vening period additional collections by Hudson have been care- 

 fully studied and reported upon by Captain Hutton, so that 

 most of the species have now been diagnosed. 



A proportion of this crane-fiy material ultimately came into 

 the possession of the German Entomological Museum at Berlin- 

 Dahlem, and through the kindness of the Director, Dr. Walther 

 Horn, the writer has been able to examine some of the doubt- 

 ful species in this collection, and the new species resulting from 

 this study are discussed in this paper. The types of the novel- 

 ties are preserved in the collection of the German Entomo- 

 logical Museum, and paratypes of certain of the species in the 

 collection of the writer. 



I wish to express my sincere thanks to Dr. Horn for the 

 privilege of examining this historical collection of crane-flies.
