Diagnosis.—There is very little difference in size between the nomi- 
nate form and the new race, although the abdomen of both sexes is 
shorter and narrower in secundus ; the preantennal area is of decidedly 
different shape, the whole frons being uniformly circular, while in 
seasetosus its sides are slightly concave, the width of the head at the 
base of the more pointed trabeculae is narrower; the internal project- 
tions on the frons are of different shape and length (see fig.), as well 
as the buccal cavity and the internal clypeal bands; the occipital bands
