SMULYAN: NEW ENGLAND TENTHREDELLA. 437 
posterior femora except on the ventral face (above continued to 
base) , a longitudinal dash (sometimes faint) on the anterior tibiae 
at base above, and a longitudinal dash at base or a line down the 
whole length on the intermediate above, posterior tibiae (some- 
times only blackish) except the greater basal portion beneath, 
and the basal segment or segments of the posterior tarsi (very 
often only blackish). 
Wings. — Fore wings somewhat clouded, entirely or only 
apical half, very often with a faint pale honey-yellow tinge; 
stigma brown, pale at base; costal cell moderately translucent; 
veins black or blackish. Hind wings hyaline, apical half faintly 
or very faintly clouded. 
Male. — The male differs from the female as follows: basal 
segment of antennae may be yellowish inside ; the pectus, and the 
meso-episternum except a small variable portion along the meso- 
epimeron yellow; only two basal terga black (third and fourth 
blackish in part) ; posterior coxae may have a broad longitudinal 
band above, and the posterior femora are broadly black above, or 
both above and behind; anterior tibiae may have a line down the 
whole length above. 
Length. — Females, 10-11 mm.; males, 9-9.5 mm. 
Redescribed from eleven females and two males. 
What I regard as the male of this species, the typical male at 
least, is here for the first time described. I have seen only two 
specimens, one in the collection of the American Entomological 
Society, and the other in the United States National ]\Iuseum. 
Tenthredella nova (AlacGillivray), which I have carefully 
examined, answers to Norton's description of eximia and is 
undoubtedly the same. Further evidence in support of this view 
is found in the fact that both were taken in the same locality, ]Mt. 
Washington, New Hampshire, and in the interesting additional 
fact that, of the fourteen specimens of both sexes which I have 
seen, ten bore labels marked "Mt. Washington, N. H.," and three 
"N. H.," and were probably taken on Mt. Washington. The 
fourteenth was labelled "Wash. Terr." Some of those marked 
"Mt. Washington" were taken near its summit; the height of the 
mountain is 6293 feet. 
I have the following additional records as regards the distribu-
