lating to the subject under discussion, but has been com- 

 pelled by force of circumstances to make his compilations 

 almost entirely from the works mentioned in the bibliography 

 accompanying the paper. 



As to the use of the term Calypteres, it is used throughout 

 the works of Air. D. W. Coquillett who evidently prefers 

 it above all others. The following definitions are taken direct- 

 ly from Dr. S. W. Williston's "Manual of the North American 

 Diptera;" Front, Peristoma or Epistoma, Propleura (Fig. 8. 

 page 32). Pteropleural bristles, Trichostical bristles, Willis-

 plainly marked "wing of CaHipJwra viridcsccns." The terms 

 given thereon may not indeed agree with those preferred by 

 certain students of phylogeny but this does not alter the fact 

 that they are the terms that have been generally used in des- 

 criptive writings for the past generation or longer. They are
