Among some interesting Diptera from Southern Pata- 

 gonia and Chile kindly sent me for determination by Dr. 

 Sjöstedt, there was included a single specimen of a very 

 primitive Blepharocerid that cannot be referred to any of 

 the known genera. The fly is of especial interest as being 

 apparently the most southern species as yet made known. 



The family Blepharoceridae or net-winged midges is a 

 small group whose members are apparently relicts of a for- 

 mer geological age. Thirteen genera are now known, distri- 

 buted in the foUowing regions: 



Apistomyia Bigot. — Paliearctic, Oriental, Australasian. 

 Hapalothrix Loew. — Paliearctic. 

 Blepharocera Macquart. — Holarctic, Oriental. 

 Philorus Kellogg. — Holarctic, Oriental. 

 Hammatorhina Loew. — Oriental (Ceylon). 

 Neocurupira Lamb. — Australasian (New Zealand). 

 Peritheates Lamb. — Australasian (New Zealand). 

 Elporia Edwards. — Ethiopian (Cape Colony). 

 Bibiocephala Osten Säcken. — Nearctic (Western North 

 America).
