foliaceous, more or less biseriately reticulate, anteriorly rounded; costal membrane 
uniseriate in greater part. Abdominal segments broadly banded with rufous.” 
Fig. 2. Acalypta lillianis Bueno, macropterous form (length, 3 mm.). 
“The macropterous form has the membrane complete, reticulately veined; in 
the brachypterous, it is much reduced and is biseriately reticulate. The pronotum 
in the former is quite high, but in the latter much reduced in area and nearly flat. 
The hemelytra are one-third longer than the body in the macropterous form, and 
in the brachypterous exceeds it but very little. The brachypterous form is nearly 
oval, while the macropterous is elongate.”

Length (brachypterous), 2.3 mm.; width, 1.2 mm.
