Genus CELATORIA Cog. 
Celatoria Coquillett, Insect Life, Vol. II, p. 235; February, 1890. 
Brauer and Bergenstamm, who did not recognize the species upon 
which this genus is founded, erroneously state that Celatoria is syn- 
onymous with Besseria.! Some of the principal differences existing 
between these two genera were pointed out by the writer in an article 
published in Psyche.? A specimen of Celatoria diabrotice submitted 
to the above-mentioned authors was by them pronounced to belong to 
anew genus near Newra, Our two species have three postsutural and 
three sternopleural macrocheetie : 
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 
to6mm. District of Columbia, College Station, Tex., and Cali-
