Ohs. The differences between this race and true A. sordida are 

 given as follows by the above-mentioned authors (p. 284) : — " Gra- 

 duation of the colours as in A. sordida ; but the blue, instead of 

 being a bright ultramarine, is very much paler and duller and with 

 a greenish cast, the whole dorsal region decidedly ashy ; ash of the 

 pectoral region much paler, and throat similar, instead of decidedly 

 whitish, in contrast ; pure white of posterior lower parts covering 

 whole abdomen instead of being confined to crissum."
