é.—Genae light orange. Labrum light orange to dark orange or ob- 
scure reddish brown, narrowly black at base and on posterior lateral 
borders with a basal median black impressed spot. Rhinarium slightly 
darker than labrum. Nasus rarely entirely black, usually a median 
transverse orange bar, sometimes this larger with margins orange, ex- 
cept at base, thus reducing the black to a submarginal black ring. 
Frons in front light orange to obscure reddish brown, naso-frontal 
suture black, wider in the median line which is produced posteriorly 
in a more or less distinct narrow longitudinal black line which joins 
a distinct short transverse crescent-shaped black area of varying width 
lying in front of the median ocellus, and between the antennae from 
which it is separated by about its own length. Color of head above 
very variable in the extent of black; in the palest there is a short 
oblique black line on either side of the median ocellus and a median 
triangular black spot back of it; starting posterior to the lateral 
ocellus a suture-like line runs outward and forward to the eye which 
it meets on a level between the antenna and the median ocellus; an- 
terior to this line all is slightly dull reddish orange with the restricted 
black markings above described, and posterior to this line the dorsum 
is solid black except for the large isolated postocular orange spots, 
and a narrow orange edging on the occiput. In darker specimens the 
ocelli are surrounded by black with a small orange spot in front of 
each lateral ocellus; from the black spot about the median ocellus a 
short bar runs outward and forward on either side toward, but not 
reaching, the antenna; the inner face of the second joint of the an- 
tenna is black, and posterior to this joint a short rounded bar runs 
toward, but does not meet, the eye; posteriorly from this bar, on a 
line with the antenna, there is a more or less distinct black connec- 
tion with the large posterior black area. In the maximum develop- 
ment of black this becomes a wide black bar; the bar from the me- 
dian ocellus reaches the antenna; midway it sends off an anterior 
branch which runs forward and inward to spread out and fuse with 
the black anterior to the median ocellus and the median transverse 
black bar on the frons; this above described anterior branch also near 
its middle throws off an anterior branch which runs outward and 
forward to the angle of the frons, then outward and backward across 
the first joint of the antenna to the inner face of the second joint. 
The orange or reddish brown postocular spots vary in size from as 
small as the area within the ocelli to fully twice this diameter when 
the lateral and posterior margining black is narrow, but in every case 
the spots are completely surrounded by black. Rear of head black, 
yellow margined against the eyes. 
Prothorax with front lobe orange, more or less black posteriorly 
on either side; middle lobe black with a geminate median orange spot
