longitudinal dark area above the accessory genitalia; two to nine with narrow 
apical black rings, most distinct on two to six and least on eight to nine; 
ten narrowl}^ black basally above. Seen from the side three has a basal black 
spot at the extreme inferior margin; sides of three to six bright red, .shading 
out only slightly towards the lower border; seven to ten darker, more obscure 
(possibly postmortem changes), with definite black markings confined to nine 
and ten; nine with a longitudinal black band on basal two-thirds of the 
segment, separated from the lower border by an almost equally wide pale area; 
above this black band is a more or less distinct dark or black area of slightly 
greater extent; ten basally with reduced homologous areas. Ventral suture 
black. Superior appendages black; inferiors reddish brown varying to black. 
Legs brown; femora black externally and more or less internally at apex; 
tibiae black lined on the anterior external face; tarsi and tip of tarsal claws, 
black; tooth on tarsal claw small, about as in myrthea. 
Wings slightly tinged with brown to more deeply tinged with yellowish 
brown; stigma dark reddish brown, covering slightly less than one cell, its 
costal length equalling two to two and one-half times its width. Wing vena- 
tion the most variable of any species. (See tabulation.) 
9 . — Genae light brown. Labrum and rhinarium as in the male. Nasus 
narrowly black at base, on either side this black produced forward and inward 
in a broad bar reaching the anterior edge of the nasus; median area brown, 
dusky at the center. Frons in front light brown. Frons above and vertex 
light reddish brown, intricately patterned with black, probably variable, here 
described as in the single female taken; in front of each ocellus is a small pale 
area; a large body of black lies between the lateral ocelli and posterior to 
them, but leaving the occipital crest narrowly pale; from this body of black, 
back of each lateral ocellus a broad black bar runs forward and outward to 
meet the eye posterior to the level of the antenna; in front of the median 
ocellus is a five-pronged body of black, on either side a bar at the level of the 
median ocellus runs outward and backward to meet the bar from the lateral 
ocellus to the eye, on either side a bar runs outward and forward to the edge 
of the frons, then turns outward and backward and ends on the second joint 
of the antenna, and the fifth bar is median and runs directly forward nearly to 
the edge of the frons; at either end of the occipital crest a pale area extends out- 
ward and forward to the eye, this is dilated at either end and is homologous 
to the two similarly located spots in the male; posterior to this, near the ex- 
treme edge of the head, is another pale spot against the eye, extreme posterior 
border with a short transverse pale bar, not reaching the eye, ahnost concealed 
in dorsal view. While the head has been described above as pale marked 
with black, this is for convenience only, as the total black areas greatly pre- 
dominate the total pale areas. Antenna with second joint pale externally and 
apically, black on inner face; remainder brown. Rear of head black, a j’el- 
lowish border, wider than in the male, next to the eyes. 
Prothorax with front lobe black, bordered anteriorly with dull yellow; 
middle lobe dull light brown with the median line and a large indefinite rounded 
spot on either side black; posterior lobe black, the outer edges and the posterior
