taxonomic significance. Punctation very variable, but always with macro- and 
micropunctures, although in some populations some of the latter are replaced by 
small granules. In some cases macropunctures bear short, small, recumbent setae, 
just visible at 25 xX magnification. 
Elytra. Fused along suture (hind wings vestigial). Epipleural carina always present, 
generally with a distinct submarginal channel inside it, at least near base. Suture 
often slightly raised. Three primary costae corresponding in position to main 
longitudinal tracheae often visible as indistinct elevations, sometimes quite distinct.
