to the front without an angular edge ; ocelli between the ver-

without closed cells in the disk; apical cells four, longish ; mid- 
dle apical nerve simple. Forward of the transverse nerve the ex- 
terior and middle nerves are sometimes obsolete. For a group of 
our small Jassides, whose elongated linear bodies give them the

yellowish-white vitta on the outer margin, interrupted 
near the middle by an oblique black line, and towards 
the apex by an oblique sanguineous one; tips dusky, 
with whitish nervures and spots ; a whitish medial line 
common to the vertex, thorax and scutel; beneath
