num, a small elongate spot sometimes on margin of meso-epimeron 
in front of meta-episternum, posterior portion of pectus from 
slightly to nearly half, and a large spot on the meta-episternum. 
Mesoscutellum generally only slightly convex; meso-episternum 
as a rule rather blunt.

the venter except the last one, and a more or less broken median 
longitudinal line on the apical portion of the dorsum, straw color.

chanters, often apparently a slender longitudinal band on anterior 
femora, anterior tibiae and their tarsi before, paler) ; anterior coxae 
more or less whitish beneath; the following parts black: anterior 
and posterior coxae as a rule very slightly at base above and out- 
side, veiy small spots as a rule on the trochanters above, a rather 
broad ring at the apex of the posterior and usually a very faint and 
very narrow ring or spot at the apex of the intermediate femora, 
apical third of posterior tibiae;, and posterior tarsi except apical 
segment (only blackish as a rule). 
Wings. — Fore wings hyaline, sometimes very faintly clouded; 
stigma reddish brown, paler at base ; costal cell from very slightly

A female from Maine (Machias, July) differs from the general

tudinal black line on the apical portion of the anterior and inter- 
mediate tibiae and on the basal segments of their tarsi above 
(broader on those of intermediate legs) ; a small spot at the base 
and the apical Iwo-thirds of the posterior tiliiae, and posterior 
tarsi except the last segment, black; stigma and v(>ins blackish.
