E. BERGROTH, THE AMERICAN SPECIES OF PLOEARIOLA REUT. 
79 
this species is unique in the colouring of the antennae. According 
to the description the first joint is pale without darker bands, but the 
pale third joint is said to have six dark bands. 
P. Parshleyi n. sp. — Head somewhat shorter than pronotum, 
its lobes convex above, the posterior lobe broader than long, laterally 
rounded, antennae fuscous, first joint somewhat passing base of abdo¬ 
men, with 9—11 white rings which generally are narrower than the 
fuscous annulations, the last white ring occupying the apex, second 
joint a little shorter than first, in its basal half with four whitish rings 
less contrasting with the ground-colour than those of the first joint, 
the extreme apex also whitish, third joint about one-third the length 
of second, fourth slightly more than half the length of third, rostrum 
pale testaceous without darker annulations. Pronotum rather strongly 
sloping, slightly narrowing from base to apex, anterior lobe laterally 
rounded, impressed in the middle with a tubercle in the apical part 
of the impression, posterior lobe broader than long, about half as long 
again as anterior lobe, the lateral ledge whitish. Scutellum very short, 
strongly transvesse, broadly truncate behind, postscutellum nearly three 
times longer thau scutellum, its spine suberect, white like the scutellar 
spine. Elytra slightly passing apex of abdomen, irrorated with pale 
brown rather than spotted, only in the apical part with distinct spots, 
stigma testaceous without spots, the intero-apical sinuosity of the 
membranal cell rounded. Acetabula and spiracles white. Legs white; 
fore coxae scarcely so long as the head, without darker annulations, 
femora slightly longer than head and anterior pronotal lobe united, 
narrowly fusiform, distinctly spinulose beneath, with two narrow in¬ 
complete rings near the middle and a broader subapical ring fuscous, 
tibiae with three incomplete rings and the apex fuscous; the four 
posterior femora with about 12 narrow blackish rings, hind femora 
conspicuously passing apex of abdomen; middle tibiae with 8—10, 
hind tibiae with about 12 blackish rings, about apical half of the for¬ 
mer and apical third of the latter dark testaceous without annulations.

Of four specimens of „errabanda “, which my friend Nathan 
Banks gave me many years ago, two belong to this very distinct 
species. It .bears a superficial resemblance to errabunda, but is not 
allied to it, the only nearly related species being the much larger 
P. canadensis Parshl., in which the scutellum and its spine are totally 
different in structure. 
P. tuberculata Banks. — Antennae fuscous or blackish, the two 
first joints each with about 10 white rings subequal in breadth to the 
dark rings, the last white ring of the first joint occupying the apex, 
the apical fourth or fifth of the second joint without white rings, first 
joint reaching middle of abdomen, second subequal in length to first, 
third more than one-third the length of second, fourth less than half 
the length of third. First rostral joint pale testaceous with a fuscous 
basal annulation, second and third joints fuscous, a lateral dot to 
second and base of third pale testaceous. Posterior lobe of pronotum
