96 . LONGICORNIA. 
The Honduras type specimen, and one in M. Sallé’s collection from Oaxaca, differ 
from Panama and South-American specimens in the more neatly defined sutural and 
lateral vitte of the elytra.

The tomentose spots in fresh specimens are pale sulphur-yellow, and not chalky 
white as originally described from worn examples.

The majority of the specimens collected at Chontales and in Costa Rica show a nearly 
immaculate and polished disk of each elytron, except the characteristic chalky-white 
streak towards the base. This constitutes the typical form ; but Mr. Belt obtained from 
special localities varieties in which the disk is almost as much spotted as in P. nivet- 
sparsus. The varieties retain the sutural and (narrow) marginal vitte; they are as 
follows :— 
Var. a. 
Elytris disco guttis plurimis parvis discretis, lineatim digestis, versus apicem evanescentibus, vittula antico- 
discoidali nulla; antennis ab articulo quarto piceo-rufis. 
Hab. Nicaracua, Acoyapo (Belt). 
Var. O. 
Elytris disco guttis numerosis, plerumque in vittas confluentibus, usque ad apicem continuatis. 
Hab. Nicaraeua, Huaca (Belt), 8.W. Yucatan (Dr. Horn).
