The reference of this fly to Pila,ria is provisional only. It
seemsunquestionablyto be related to the Nearctic lenta O. S. andallies, the strict generie position of whieh still remains in question. Pilaria triangu,lorfs is an even more aberrant speciesthan

all features that set off the pre."nt fly as a very distinct species.
