specimens similar in size and shape ; derm clearing to a consider- 
able degree on treatment with caustic potash, but showing more 
or less distinctly numerous, large, rather closely crowded areola- 
tions, each with a tiny pore, these areolations similar to those 
found in species of Saissetia, but much less conspicuous on 
account of the much lighter chitinization, more pronounced 
along the body margin ; antennae normally 7-segmented, the third 
sometimes incompletely divided, the measurements of those ex- 
amined as follows (in microns): II, 35-39; III, 39-48; IV, 
35-37 ; V, 22 ; VI, 18-22 ; VII, 35-39 ; legs normal, rather small 
and slender, claws rather strongly curved at tips, digitules all 
long, slender, knobbed at tips, but one of claw about three 
times as thick as the others; spiracles not unusual; beak ap- 
parently 1-segmented, very short; derm with numerous, but 
scattered simple pores over dorsum in center of areolations,
