lieve that the same relation can be traced to genera and, indeed, have 

 in mind certain adult characters which we think would work out 

 excellently. At present, however, we are restrained by the limitations 

 of our field from applying these ideas. 



After writing the above we have seen a recent classification bv 

 Mr. Coquillett (Science, n. s., xxiii, 312, 1906) in which one of our 

 characters, the tarsal claws of the female, is used to good effect. 

 Otherwise the arrangement is based too largely on larval characters* 

 to be of value in the present connection. We wish to compare our 

 arrangement, based solely on larval characters with one based solely 

 on adult characters. The only one so available is that of Mr. Theo- 

 bald, which does not stand the test of that comparision, for the reasons 

 we have discussed.

*Miss Mitchell's generalization, adopted by Mr. Coquillett, about the egg- 

 laying habits is fallacious, and will not hold. This might have been anticipated 

 as it is clearly an adaptive character.
