posterior spot on either side, this sj)ot opposite a larger spot on the posterior 
lobe. Pro])leuron black in front, border and posterior half reddish yellow. 
Thorax red or reddish brown above, j)aler and duller below, in a few cases 
with traces of greenish, ventrally; black markings variable as follows: a 
more or less irregular mid-dorsal stripe, and irregular antehumeral, enlarged 
above, at the middle and below (where it is posthumcral), usually divided 
between the median and lower enlargements and nearly so in many eases be- 
tween the upper and median enlargements; an inferior spot on the mese- 
pimeron, which may be developed through all intermediate stages into a stripe 
for nearly the full length of the sclerite, this maximum development rare; a 
median round si)ot on the first lateral suture; a stripe on the second lateral 
suture, more or less interrupted below the upper rounded end: metepimeron 
more or less darkened in its median area. 
Abdomen red, segments two to six brightest, segment one duller with a me- 
dian basal black spot, and sides below, dusky or black; two with a longitudi- 
nal black or dark band, just dorsal to the accessory genitalia, and just above 
this a shorter sub-basal longitudinal bar, which may be fused or not, with 
the bar below it, base and apex very narrowly black; three to ten nar- 
rowly ringed apically with black, this obscure or diffuse generally on seven 
to ten; inferior lateral edge of three to six or seven black, brown, or yellow 
or red, variation j)robably due to postmortem changes; extreme ventral edge 
of three to six very narrowly pale yellow, more conspicuous in some specimens 
than in others; beginning on two is a trace of an obscure subapical lateral 
spot, which ]>rogressively posteriorly grows larger and more distinct, joining 
with the apical black ring to form on seven to nine a distinctly dark, but ill- 
defined apical area; seven to ten generally duller and more yellowish; apical 
half or more of eight and most of nine and ten sometimes largely black in 
lateral view, in which case ten is largely black throughout. \ entral suture 
black. Superior appendages black, brown at base and below; inferiors brown. 
Legs light brown; femora with numerous darker brown mottlings, and apex 
darker, these brown markings sometimes fused to make the entire dorsal 
surface dark or black with the tibia dark basally, and on the ventral surface; 
tooth on tarsal claw minute, slightly larger than in rubrivcnlris. 
^^'ings clear or slightly tinged yellowish brown: stigma light yellowish brown 
to Iji’own, covering less than one cell, its costal length not quite twice its width. 
In one right hind wing there is a transverse cross- vein in the triangular terminal 
cell behind Cui. In both hind wings of another, the right hind wings of two 
others, and both front wings of another, Ciu terminates at the border with the 
descending cross-vein from the first postnodal; in another right hind wingCui 
meets this descending cros.s-vein just below its middle in the marginal cell. 
In both front wings of one specimen, and in the right front wing of another 
there is a short floating vein as a continuation of A ; in the latter specimen, both 
hind wings and the left front wing, and in both hind wings in another specimen, 
this floating vein is continued clear across the cell. Were this condition normal 
it might be described as Cuj terminating against the next descending cross- 
vein after the quadrangle. In the left front wing last mentioned above Cuo
