Apical band not so broad . . . . . . A . rossii. 



Legs speckled. 



Large species A . ludlowi. 



Smaller species . . . . . . . . A . mangyana. 



(b) Mesothorax completely clothed with true scales. 



Abdomen without lateral tufts. 



Group 9. Palps moderately shaggy only. Bifurcations of second and 

 fourth veins both sites of pale interruptions. Head scales as

2 Here again there is confusion in the nomenclature. The type species of 

 Laverania Theobald ( = Nyssorhynchus Blanchard) is A. (Cellia) argyrotarsis. 

 The well-known group of so-called Nyssorhynchus, therefore, is incorrectly so 

 called.
