 brown ; eyes tawny olive clouded ventrad with bistre ; antennae wal-

In addition to the type two specimens of this species, one male and 

 one female, in the U. S. National Museum collection, from Los Angeles 

 (Coquillett), have been examined. These individuals agree with the 

 type in all essential characters, the female, however, being somewhat 

 larger. The measurements of these specimens are as follows :
