 black, with jtale line at base of tegiilie. Abdomeu like secondaries."

Habitat — Massachusetts. 



A very close ally of bicarnea. 



I have seen only a single specimen, which fully agrees with the above 

 description, and this is now in the coll. U. S. N. Mus. It is much larger 

 than given by Mr. Grote, expanding fully 40""". There is no locality 

 label, and I have no idea where tbe specimen came from. It is easily 

 known by its resemblance to hicarnca, but lacking the carneous shade.

A fair representation of this species is in the Illustrated Essay, show- 

 ing it to be related to bicarnea, from which it differs in the discolorous 

 orbicular, and the Mant of the brown patch at inception of t. p. line. I
