most of tlie structural cliaracters I liave been able to discover, but 

 diflfer iii the comparative length of the pectinations of the antennae. 

 The species are Philometra longilabris, Grote, and Philometra 

 SERRATicoRNis, Gfote. I designate the former as the type of the 

 genus. At the moment I prefer to separate the genera I have here 

 discussed on other than antennal peculiarities. 



I have received from Mr. Lintner some very curious examples 

 of Zanclognatha laevigata, showing the excessive variability of this 

 species. Sometimes the median space is dark, bronzed or purpled, 

 sometimes clear when the base of the wing and the hind region are 

 obscurely tinted. I have indicated the existence of these variational 

 tendencies in my original description of the species which was made 

 from large material.
