404 Mr. G. W. Kirkaldy on the 
on the corium and one at the base thereof, black ; apex of mem- 
brane testaceous. 
3. Apical half of hemielytra black, basal half orange-brown, or 
deep rich crimson-red (in some individuals assuming almost a 
purple hue), which may be more or less clouded with black. 
[? N. impressa, Fieb.] 
4. Black ; except the basal half of clavus and a small spot near 
the submargin (about the centre) of the exocorium, which are 
roseo-testaceous, and a scarlet irregular (usually pentagonal) 
spot on the apical margin of the corium ; the exocorium spotted 
regularly with brownish crimson; apex of membrane sordid 
testaceous. 
5. When living, “ clear ivory white, with irregular dark spots on 
the hemielytra, and the large spots at base of corium . . . con- 
spicuous, greenish white” (Uhler én /itt.) ; but after death, much 
tarnished, the white changing into pale dirty bronze green. 
Ale : basal nervures crimson, the others yellow brown. Pedes : 
cox black, intermediate tibial spur small, slender, not tipped with 
black. Abdom. dorsum: segment 1 black, 2-6 brilliant scarlet, 
7-8 reddish-testaceous. 
Abd. venter black, connexivum and central carina green. 
In all five varieties, the membrane lobes are subequal. 
The ordinary pale forms may be known as var. odara, 
the fifth variety as var. geala, while Fieber’s “ impressa ” 
may be retained as a varietal name for the crimson and 
black forms. 
The disposition of the scarlet colour of the dorsum 
abdominis, and its actual shade, vary greatly: in some 
examples the second segment is suffised with black, 
the third to the sixth being more or less scarlet, while 
in others only the central parts of these segments are 
thus coloured ; the hue varies from orange-red to deep 
crimson. It is curious that this colour has not, as I 
believe, been previously noted. 
Long. 13-15 mm., lat. 4°9-5 mm.

Hab. America. Prof. Uhler (1875, Wheeler’s Exped., 
xu., p. 841) writes: ‘It seems to extend entirely 
across the continent [7.c., of N. America], north of the 
fortieth parallel, and on the Pacific side extends as far 
south as San Francisco ;” in a recent letter he adds: 
“ distributed from the upland cold water of Maryland all 
the way north to British America, and across Canada to
