1 In tbe Trans. Amer. Ent. Soc, Vol. XIII, p. 303, Dr. Williston doubtfully refers 

 this species to tlie genus Saundersia, but in the Biol. Cent.-Amer,, Diptera, Vol. II, 

 p. 22, van der Wulp states that this reference is very doubtful, since Walker men- 

 tions the palpi in his description. This is the ouly species, however, from the 

 eastern part of North America that at all agrees with Walker's description, aud the 

 fact that he mistook the folds in the mouth for palpi will not at all surprise any 

 student familiar with the doiugs of that author.
