Some Nomenclatorial Notes on the Dipterous Family 



Trypetidae. 



By E. T. CRESSON, JR. 



There has recently appeared in the Memoirs of the Indian 

 Museum, Vol. Ill, No. 3, a paper by Prof. M. Bezzi, entitled 

 "Indian Trypaneids (Fruit flies) in the Collection of the 

 Indian Museum." This paper not only treats of the Indian 

 species but gives an entirely new classification of the genera 

 of this family. There has long been a want of such a reor- 

 ganization based more upon structural characters than here- 

 tofore, and Prof. Bezzi, who has given much study to the 

 fruit flies of the world, has certainly furnished an excellent 

 foundation for the establishment of the genera of this family. 



The family is divided into two subfamilies namely, Dacinae 

 and Trypaneinae. The latter is further divided into three 

 tribes, Ceratitininae, Myioptininae and Trypaneininae. The 

 subfamily Dacinae is not represented within the nearctic zone. 

 Tt probably includes the remarkable Toxotrypana G'ers. of 

 Mexico. The tribe Ceratitininae is characterized by having 

 the cilia of the posterior orbits composed of fine black bristles
