 vestigial; tongue ahsent or represented at most by minute projections 

 that do not extend beyond head vesture; labial palpi 3-segmented 

 in most primitive forms, but usually reduced to minute, hairy tuber- 

 cules. Antennae less than half length of forewing, either bipectinate 

 or simple; scape without pecten. Ocelli absent except in few primi-

 Rs extending to outer margin below apex; base of medius almost

 intercalary cell; lA at least partially present, either curving to fuse
