There isnol enough similarity between this species and C. regina Johns, a or bet 

 this and the gigantic ( '. h rgiu h nsis Pet. &to warrant uniting them, as is done.by Cleve. < 

 The Bpecies is, however, a very variable one both in size and markings.

 A discussion of the separation of this species from C. dirupta Greg., with which it i- 

 united by Cleve. may be found under the latter species, h may be here stated that 

 the union of the above sigmoid forms agrees with I>e Toni 4 in so far as that h< 

 admit them under C. dirupta, but either gives them separate rank or unites one or two, 

 chcipu ns i !leve and ( '. arctica < lleve.
