Family TANYDERID^ 



In 1920 the writer erected the subfamily Bruchomyiinse for 

 the new genus and species, Bruchomyia argentina, from the 

 Sierra of Argentina. Later, Edwards ^ described a new 

 species of the group from amber. In the same paper Ed- 

 wards indicated that the insufificiently known genus Nemo- 

 palpus Macquart {Palaeosycorax Meunier) was a member of 

 this subfamily, which includes, besides the genotype, N. flavus 

 Macquart (Canary Islands), the fossil species N. tertiarice 

 (Meunier) and N. molophilinus (Edwards). Mr. Edwards 

 believed that the group was more properly referable to the 

 family Psychodidse and proposed the subfamily Nemopalpinse 

 to receive the species of Nemo palpus and Bruchomyia. The 

 writer can see no just reason for rejecting the subfamily name 

 Bruchomyiinse, based on the genus Bruchomyia, in favor of 

 the earlier described Nemopalpus. The name Bruchomyiinse 

 was the first higher group to be proposed for these flies and 

 if any rules of priority apply to groups of animals higher than 

 the genus, this name should be retained. It is on this same 

 basis that the family Tanyderida is used, the genus 

 Tanyderus being the third to be proposed. If the earlier 

 names are used the family will become the Macrochilidse or
