Genus CELATORIA Coq. 
Celatoria Coquillett, Insect Life, Vol. II, p. 235; February, 1S90. 
Brauer and Bergenstamm, who did not recognize the species upon 
which this genus is founded, erroneously state that Celatoria is syn- 
onymous with tfesseria. 1 Some of the principal differences existing 
between these two genera were pointed out by the writer in an article 
published in Psyche. 2 A specimen of Celatoria diabroticce submitted 
to the above-mentioned authors was by them pronounced to belong to 
a new genus near Xea'ra, Our two species have three postsutural and 
three sternopleural uiacroclmeta^ : 
Palpi yellow, front in both sexes wider than either eye, front pulvilli 
of male about one-half as long as the last tarsal joint; length, 4 
to 6 mm. District of Columbia, College Station, Tex., and Cali-
