band*, and a basal spot brown ; sub-costa runs into costa at mid- 
dle of the fore wing; the radius does not curve inward as much 
at the pterostigma as in P. maculosa and the wing is less slender 
than in that species. Abdomen short, second segment not 
produced behind ; 6th segment tapering, no projection above ; 
7th an 8th sub-equal, 7th ob-conical, curved at base, more 
swollen above than in P. maculosa, 8th more regularly conical 
and not so large ; 9th short and broad ; forceps stout, appen- 
dages reaching to base of claws. 
Habitat, Sea Cliff,. N. Y. Differs from P. nebulosa and 
7 naculosa in shorter and stouter forms. 
I have seen only the type specimen of this species. It is 
a male and is deposited in the Banks collection. 
As affinis has been used by Leach for a European species, 
it seems desirable to change the name of the American species, 
although affinis of Europe is not considered a distinct species 
at the present time. 
Panorpa latipennis n. sp. 
Plate LIX, Figs, i, j. Plate LXI, Fig, ^2. 
Anterior wing: male 14 mm., female 16 mm. Brown, last 
three or four abdominal segments lighter, rostrum and basal 
segments of the antennae brown, remainder of antennae fuscous; 
coxae fuscous, remainder of legs pale yellow ; wings hyaline, 
apex, a pterostigmal band geniculated at the middle, and ab- 
ruptly widened at costa, a costal spot, a band interrupted at 
middle, and a basal spot brown. The apical patch of brown is 
divided or nearly divided by hyaline, the basal spot is absent 
on the hind wings, all the wing markings are very narrow and 
somewhat broken, and most of the veins are brown. There, is 
no horn on the 6th segment of the male. A male and female 
in the Hubbard and Schwarz Collection taken at Detroit, Mich- 
gan, June 2, and a female in the Banks Collection taken in 
New York. 
The large size separates this species frorh others of its group.
