to receive head; hind margin right or obtuse angled; surface of prozona

disk of pronotum fuscous. Tegmina yellowish brown sprinkled with 
fuscous, usually three fuscous crossbars. Wings yellow at base, with 
broad curved band of black from the middle of the outer border to a

Genus ArpTiia Stal. 
“Body compressed, glabrous. Pronotum granulate, median carina 
sometimes sulcate, sometimes entire. Tegmina of one color, very densely 
reticulate, apex quadrate-areolate, sometimes pellucid; the whole with 
minute dark dots, or many larger dark blotches, never with crossbars. 
Wings with a broad dark band on the hind margin, from whjch a stripe 
runs, on the outer edge, towards the base. Median vein frequently 
united with the discoidal. Hind femora stout, margins carinate, inner 
surface black with two yellow stripes. Hind tibiae blue, yellow at base 
(in dried specimens fuscous in the basal half, or if faded, with fuscous 
rings). Arolia between the claws of the tarsus minute or lobiform. 
“The species usually have a granulate pronotum and variously colored 
wings. 
“The species which form a part of this genus are very similar to one 
another, and as they vary much, sometimes in the form of the frontal 
costa, sometimes in the color of the wings which pass readily from 
red to yellow orange, they are very difficult to distinguish, and still 
more, to describe.” — Saussure. 
20. Arphia pscudonictana Thomas. — Vertex with marked median and 
lateral carinae, distinctly separated from the frontal costa, which is 
flat, slightly sulcate at ocellus. Foveolae large, oblong. Pronotum

once, in front of middle; lateral carinae more distinct on metazona than 
on prozona. Tegmina surpass abdomen in both sexes.

fuscous bars across the black and usually a red or tawny stripe along 
the median border. Wings red or orange at base. Hind femora black,

in upper fourth. 
Measurements : — Length of body, male, 22 mm., female, 2G mm. ; teg- 
mina, male, 22 mm., female, 24 mm.; hind femora, 14 mm. 
Genus Dissostcira Scudder. 
“Vertex with the disk sub-pentagon al or ovate; the front half a little 
downward sloping, its front margin angulate; the lateral carinae low; 
the median carina present but indistinct; the foveolae short, triangular. 
Frontal costa sulcate, a little narrowed below the ocellus. Pronotum 
with disk of prozona sloping, that of metazona fiat; front margin trun-
