REMARKS ON THE GENUS SCAPHOIDEUS WITH A 
REVISED KEY AND DESCRIPTIONS OF NEW 
AMERICAN SPECIES. 
Herbert Osborn. 
A 
Since the publication of my paper on this genus in 1900* there 
have been a number of other species described, and I have secured 
records of distribution which considerably increase the range for 
a number of the older species, and moreover have recently obtained 
material which adds to these records, so that it appears to be an 
appropriate time to review the work presented in that paper. 
At the time the paper was written the genus seemed to be 
quite strictly American and with the exception of a species 
described from the West Indies, St. Vincent Id., by Professor 
Uhlcr, the range of the genus being distinctly Nearctic. A species 
described from Japan, and more recently the description of two 
^ ether species from the Palearctic region show s that the genus has 
a wider range and would indicate for it a greater antiquity. Of 
the species which have been described as American since my 
previous paper on the genus, three are distinctly western, one 
distinctly eastern, and one southern or southeastern in range. 
Four species apparently new are described in the present paper. 
But little has been added with reference to the life histories 
of the species, and in general the habits of the species are such 
that observations upon the life histories seem not to be very 
readily made. Considering the accessibility of my earlier paper 
it is deemed unnecessary to repeat descriptions or bibliography.
