localities, Mr. Johnson informs me that he has specimens record- 
ed from Hampden, Me., Julj" 10 (C. W. J.); from Wonalancet, 
N. H., Sept. 13, (Cushman); Jackson, N. H., Sept. 25, (Bryant); 
from Pelham, N. H., Aug. 31; from Danvers, Springfield, Nan- 
tucket, Brookline, and Auburndale, Mass.; June 29-Sept. 14; 
from Kingston, R. I., July 19 (Barlow); and from WestHlle, 
Conn., June 20 (Britton). 
Dinera futilis is a manuscript name of H. E. Smith’s which 
has come into use in lists and other records although the species 
has never been described. I have been asked by Mr. Johnson 
and others to publish this description, which I am pleased to do, 
using of course, the name by which the species has already come 
to be known. Our species is exceedingly close to that known in 
Europe as Dinera grisescens Fall., of which 1 have before me 
five males and three females, obtained from the Vienna Museum. 
The only superficial difference appears to be in a tendency for 
the 3 ^ellowish cast, on mid-ventral line and along posterior mar- 
gins of abdominal segments one, two and three, on ventral side, 
to be somewhat more pronounced in the European than in the 
American form. The variation in chaetotaxy is the same for 
both species, but being loath to pronounce them the same, I 
relaxed two males of each series in order to examine the genitalia. 
The inner forceps of both are fused, but there are certain other 
very appreciable differences, which surely warrant keeping the 
two species separate. The fused inner forceps in futilis exhibit a 
low, narrow carina, and are clothed with dark hairs at the base. 
In grisescens this structure is totallj^ devoid of a carina, and 
bares only pale hairs at the base. 
Holotype, male, from Atco, N. J., retained at Ithaca. Al- 
lotype, female, from Intervale, N. H., deposited at Boston 
Society of Natural History. Paratypes at Ithaca, Boston and 
Albany. 
Note: It is the author’s intention to arrange, eventually, 
for the deposition of certain paratypes at the U. S. National 
Museum in Washington.
