Our single species is yellow, the sides of the front, third joint of

1 In the Trans. Amer. Ent. Soc, Vol. XIII, p. 303, Dr. Williston doubtfully refers 
this species to the genus Saundersia, hut in the Biol. Cent.-Amer., Diptera, Vol. U, 
p. 22, van der Wulp states that this reference is very doubtful, since Walker men- 
tions the palpi in his description. This is the only 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 doings of that author.
