prosternum, propleura except narrow upper portion of lateral

entirely absent), pronotal lobe, a V-spot on prescutum (very 
rarely absent), tegulae, transverse mesoscutel extensions, post- 
tergite except a narrow median longitudinal area usually, the 
upper half to two-thirds of the meso-epimeron, raeso-episternum 
except a longitudinally elongate spot on the upper anterior por- 
tion along and touching the meso-epimeron, the pectus except 
slightly meso-anteriorly usually and a rather broad oblique band 
on each side (these bands may be broken and often entirely absent 
but their course is indicated by brownish or very faint brownish 
bands) , transverse metascutel extensions, the met^-postscutellum 
except at its juncture with the abdomen (very rarely almost 
entirely black), the upper half to two-thirds of the meta-epimeron, 
and the meta-episternum. Mesoscutellum generally quite 
strongly convex; meso-episternum generally sharply pointed.

whole length of the intermediate and posterior above (much 
broader apically on the last), a longitudinal line on the interme- 
diate tibiae and a slightly interrupted one (interrupted some- 
what basal to center) on the anterior, the posterior tibiae above 
and sometimes the whole apical portion also ; the apical portion of 
the posterior tibiae, and the posterior and intermediate tarsi as a 
rule, brownish. 
Wings. — Fore wings hyaline or faintly clouded with pale 
honey-yellow; stigma from light brown to dark brown, as a rule
