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. III, 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. 
It probably includes the remarkable Toxrotrypana Gers. of 
Mexi¢o. The tribe Ceratitininae is characterized by having 
the cilia of the posterior orbits composed of fine black bristles
