rowed above; basal callus shiny, dark brown, protuberant, transverse, and 
touching eyes; median callus a narrow line slightly widened above and usually 
joined to basal callus; at vertex a subquadrate, partially denuded area with a 
slight median tubercle; subcallus slightly protuberant, light gray, tinged with 
yellow. First two antennal segments yellow, with black hair, the first not 
swollen above; third black, the basal half of basal portion sometimes orange
