All these specimens belong to Hetewrina americana, and as Say 
gives the locality Massachusetts, it may.be that the type is among 
them. Atleast in Say’s description nothing is given to believe the 
contrary. Of No. 48 only the male from North Carolina is in the 
collection, and the Cambridge specimen is lost. The latter only was 
seen by Say, as he stated the specimen to be a female.

Say describes the species from Massachusetts from Dr. Harris’ 
specimen; of course the specimen in the collection is a typical one. 
This is the only specimen of this interesting species I ever saw, 
either in Europe or America. ‘The inferior processes are wanting in 
the specimen.

Say describes them from Indiana and Massachusetts. In the col- 
lection is a male from New York, not marked in the catalogue, but 
undoubtedly L. rectangularis.
