 Lpiphragmophora areolata crassula (Dall). 



Fig. ; E. crassula Dall, Proc. Phila. Acad. Nat. Sci., 1900, p. 

 100, PI. VIII, fig. 3. 



This subspecies, which bears an analogous relation to 

 areolata that tryoni does to kelletti, has been referred to by 

 Binney under the name of Euparypha levis (Pfeiffer). 

 Pfeiffer's type was a dwarf specimen of areolata. The only 

 available name is crassula Dall. Occasionally specimens in any 

 considerable series of areolata are referable here.
