Genus P}iotn]>.ns Blake. 



Here belong a large part of the male forms whieli fly to light at night 

 so commonly in many parts of the west. Sometimes dozens may be 

 collected on a single evening and then again weeks may elapse without 

 seeing one. Hence it is only through residents in the southwest that ade- 

 quate collections will ever be made or the sexes properly associated. The 

 following forn s are, of course, all described from males. Among these 

 species, the two posterior ocelli are usually about the same distance from 

 each other as from 'the eyes. The reticulation of the metanotum is as a 

 rule much more regular than in Odo7itopholopsix, and the abdominal 

 fringes of plumose hairs occur on rarely more than one or two segments 

 in these species and J^re sometimes entirely wanting.
