(Fig. 10)

elytral margin very light brown. Head — densely punctate dorsally, 
with longitudinal striation on antennal tubercules; whole surface 
micro-reticulate. Pronotum — wider than long, slightly wider than 
head; densely punctate on surface, with somewhat granulate aspect; 
posterior angles more or less square; lateral margins turned upwards, 
crenulated; median line in a slight depression which continues on 
each side anteriorly (forming a Y). Elytra — with 8 irregularly 
punctured sulci; 7 discal interstices more or less smooth, convex; 8th 
and 9th interstices very slightly indicated only, mainly posteriorly; 
almost twice as wide as pronotum, less than twice as long as wide; 
elytral margin with setose punctures. Measurements — holotype, 3.7 
X 10.3 mm; paratype, 4.1 X 10.9 mm.

Inna megala is very similar to planipennis Bates, which is only 
known from Mexico. The two species are of about the same size; 
planipennis has a less densely punctured head, especially between the 
eyes; the pronotum of megala is more transverse than that of plani- 
pennis. 
Specific name: megala is derived from the Greek adjective megas , 
meaning large.
