The scheme drawn in the Biologia Centrali Americana, considers Stal’s sub-genera 
Microschema and Lophopelta, as comprised in the genus Platycotis. The distinctions 
made by Stal do not appear to be very marked. For the chief differences the student 
may be referred to page 41 of Fowler’s Monograph in the B.C.A. 
The genus Lophopelta is represented by Platycotis histrionica of Stal. 
The following species have been described by some authors, and may be added to 
the list of Hoplophorinse previously set forth in this Monograph.
