" A Burmese representative of the little group of Alycaei which 

 comprises A. constrietus B., A. bembex B., and A. oiipliorus B. 

 A. graphics, although much more globose than any of the others, 

 is in some respects intermediate between constrietus and otiphorus, 

 resembling the first in size and somewhat in form, and the latter 

 in the reflexed left edge of the outer peristome. This character, 

 however, is by no means so much developed in the Burmese as in 

 the Darjiling species. The present has a more marked sculpture
