ANTHOPHILA. 
CTENOAPIS, gen. nov. 
The longer joint of the four posterior calcaria pectinated ; 
the spurs bifid ; the teeth unequal in length. Labrum deeply 
or moderately deeply incised in the middle at the apex. 
Mandibles unidentate. Radial cellule not quite so long as the 
two cubital cellules together ; it is indistinctly appendiculated 
at the apex, which is moderately acutely pointed. There are 
two cubital cellules; the second receives both the recurrent 
nervures ; it is narrowed at the top, being there about one 
third of its length on the lower side. ‘Trophi long, the 
maxillary palpi ?, the labial ?-jointed. Antenne stout; the 
basal joints of the flagellum broader than long, the apical 
longer than broad. Hyes long, parallel, reaching near to the 
base of the mandibles. Ocelli in a curve [.*.]. 
The body is only moderately pilose. ‘he legs are stout ; 
the hinder femora, tibize, and metatarsus are thickened; the 
recurrent nervures are received near the transverse cubitals ; 
the transverse basal nervure is interstitial. In the female the 
hinder tibiee and the metatarsus are thickly covered with long 
soft hair; the second and following ventral segments are 
fringed with long soft hair. The antenne are placed above 
the clypeus and shortly below the middle of the eyes; the 
apical joint of the hinder tarsi is long and curved, longer than 
the middle three joints united. ‘There is a short distinct 
longitudinal keel on either side of the mesonotum ; the tegule 
are moderately large; there is no area on the base of the 
median segment; the face and clypeus are bare and flat. 
The general form of this genus is somewhat like Panurgus, 
but it cannot readily be confounded with that genus. The
