NOTULAE ENTOMOLOGICAE II, 1922 
the American species is easily overlooked owing to its smallness 
and white colour, but it is readily seen if looked at against a dark 
surface. 
P. errabunda Say. — First antennal joint brownish with about 
5 pale rings. The white rostrum with two rings to the first joint and 
often the base of the second brown. Hind lobe of pronotum a little 
broader than long, one-half longer than fore lobe. Scutellar spine 
horizontal or a little upturned. Elytra with a rather broad oblique 
unspotted area behind the stigma, which has two or three fuscous 
spots, the intero-apical sinuosity of the membranal cell obtuse-angled. 
The white fore-legs with one anteapical ring to coxae, four rings to 
femora, and three to tibiae brown, apical ring of tibiae not narrower 
than the median, femora distinctly spinulose beneath. Hind femora 
shorter than in any other American species known to me. 
I have this species from «Eastern Br.“, D. C., and Falls Church, 
Virginia. Van Duzee has recorded it from four localities in Florida 
and one in Jamaica, but „ errabunda* as understood by him consists 
of two or probably three different species, all of which are provided 
with a pronotal tubercle and none of which is allied to errabunda. 
The above described species is errabunda as understood by 
Uhler and Heidemann. Several years ago I saw in the collection 
of the Boston Society of Natural History a specimen determined by 
Say himself as errabunda. It seems to be this species, but is badly 
mutilated. Whether P. maculata Hald. really is the same species 
seems to be uncertain, although Uhler stated that he was in pos¬ 
session of the type and that maculata is identical with errabunda. 
Van Duzee in his Catalogue cites only Haldeman’s first descrip¬ 
tion of maculata. In the American Journal of Science, Ser. 2, Vol. 
IX (1850), p. 108—111 is a paper by Haldeman, in which he gives 
a somewhat different and a little more complete description of the 
species. 
P. californica Banks. — First antennal joint white with 10 or 
11 black rings, the last (subapical) ring broader than the others. First 
rostral joint white with a submedian blackish ring, second and third 
joints blackish, a very narrow ring to the second and the base of 
the third white. Hind lobe of pronotum not broader than long, twice 
longer than fore lobe. Scutellar spine as in errabunda, but usually 
shorter. Elytra behind the stigma with a narrow oblique unspotted 
area continued inside the stigma as far as to the radial cross-vein, 
stigma with one or two fuscous spots, its inner margin between the 
base of the radial cross-vein and the apex often sanguineous or red¬ 
dish, the intero-apical sinuosity of the membranal cell rounded. The 
white fore legs with two rings to coxae, base and four rings of femora, 
and three rings to tibiae blackish, apical ring of tibiae much narrower 
than the median, femora very shortly spinulose beneath. 
The specimens examined by me are from Palo Alto. 
P. hirtipes Banks. — If the description be correct (and Parshley, 
who records the species from Vancouver, makes no comment on it)
