to orange brown on a large median occipital blotch behind ocellar 
triangle, on and between antennal sockets, on much of median 
field of face except above, in clypeal suture, medially on apex 
of clypeus, in much of malar space, on apical 1/3-1/ 2 of lower 
half of temple, and on most of postocciput, as well as with shining 
black on most of front, on much of vertex and occiput, and apically 
on upper half of temple; mesosoma shining pale red with some 
very obscure whitish staining, especially on scutellum, tegulae, 
subalarum, speculum, mesosternum, and apicad on lower meta- 
pleuron; first gastric tergite shining pale red except for a broad 
white crossband on its apical fifth and an even wider, somewhat 
irregular black area just preceeding the white band; the following 
tergites black with complete white apical bands on 2-7 and a 
medially interrupted white apical band on 8; fore and mid legs 
pale red to yellowish red on tibiae and tarsi, with a little dusky 
apicad on third tarsomere and with fourth and fifth tarsomeres 
blackish; hind leg with coxa, trochanter, trochantellus, and femur

with blackish on about basal sixth of first segment, on apical 
half of fourth, and on all of fifth segment; wings hyaline. 
Flagellum: segments 1-9 a little compressed with 10 and fol- 
lowing somewhat thickened and then attenuate toward tip, the 
first segment 6.1 as long as deep at apex. Face: mat and finely 
granular with mostly well spaced, medium-sized shallow punc- 
tures. Temple: smooth and shining with small, sparse punctures. 
Mesoscutum: smooth and polished with only a few tiny, scat- 
tered punctures that are best developed anteriad. Mesopleuron: 
prepectal carina reaches dorsad to about opposite upper 0.40 
of hind margin of pronotum; no ridge on prepectus opposite lower 
hind corner of pronotum; surface smooth and shining on most of 
upper third, on speculum, and on the numerously but finely punc- 
tate prepectus but becoming mat with delicate irregularly longi- 
tudinal wrinkling on most of lower 2/3. Lower metapleuron: 
dully shining with very fine oblique wrinkling and micro-shagreen- 
ing and scattered tiny, obscure punctures emitting moderately 
long but mostly well spaced setae.
