TWO GENERA OF TRYPHTIDAE—MALLOCH 3 
Fore tarsus short and stout, the basal segment not over twice as long 
as thick, with some erect, outstanding, stiff hairs on the ventral 
surface, sometimes projecting forward below the surface of the second 
segment, and the intermediate segments between it and the fifth 
usually with outstanding hairs on their anterior edges that are a 
little longer than the segments; fore tibia rather thicker than usual 
and with a series of minute erect stiff hairs on the dorsal surface___ 5 
Fore tarsus not abnormal in form or armature, the basal segment at 
least three times as long as thick, the other segments without out- 
standing anterior hairs and the fore tibia not thickened and with
