SMULYAN: NEW ENGLAND TENTHREDELLA. 425 
Male. — The male differs from the female as follows : greater 
part of lateral face of pronotum straw color; an approximately 
right-angled band on the meso-episternum, posterior mesal half 
of pectus, and basal half of venter entirely straw color; inter- 
mediate coxae black only at base above, the posterior coxae 
except inside and inner longitudinal half beneath, and the apical 
two-thirds of the posterior tibiae black (continued to base above) . 
Length. — Females, 11-13 mm.; male, 11 mm. 
I have seen only one male. It is in the collection of the Boston 
Society of Natural History. 
This subspecies approaches fisheri Rohwer from Maryland, and 
m-ay prove to be the same. 
Habitat. — Sharon, Auburndale, and Woods Hole, Massachu- 
setts (June and July) ; Farmington (Norton) and Westville, 
Connecticut (June). I have records also from New York, New 
Jersey, and Virginia, but they may refer to lobata lohata.

Female. — Head. — Yellow; the following parts black: back of 
head except compl(>tc or incomplete margins of occiput (lateral 
lines often extend for some distance on vertex-plate), a large spot 
on front above antennae and vertex, distinctly trilobed anteriorly 
and somewhat less distinctly laterally, extending longitudinally 
from the posterior margin of the head to between the 
bases of the antennae medially (rarely the posterior lateral 
lobe is almost entirely cut off from the remainder of the spot 
by a very narrow line), an elongate spot behind the upper
