FD — facial distance. The length of the head in full frontal view, 
from the crest of the vertex to the apex of the clypeus. 
LID — lower interocular distance. The minimum distance be- 
tween the lower margins of the compound eyes. 
MID — middle interocular distance. The maximum distance 
between the inner margins of the compound eyes. 
OOL — ocellocular length. The minimum distance between the 
outer margin of the lateral ocellus and the inner margin 
of the compound eye. 
POL — postocellar length. The minimum distance between the 
inner margins of the lateral ocelli. 
TFD — transfacial distance. The maximum distance across the 
head from the outer margin of one compound eye to the 
outer margin of the other. 
UID — upper interocular distance. The minimum distance between 
the upper margins of the compound eyes. 
Atopagenia Wasbauer, new genus 
Female. Large wasps, the size of small Pepsis. Head (fig. 1) 
with clypeus very long and wide, extending laterally well under 
compound eyes, anterior margin strongly gibbous; malar space 
well developed; apex of mandibles broad, tridentate (including 
apical cusp); mentum with a number of long, slender, dark hairs; 
palpi long, maxillary palpi extending beyond apex of anterior 
coxa; labrum not exposed in anterior view, its apex truncate; 
occipital carina extending dorsally onto vertex in a short loop. 
Mesosoma with disc of pronotum gently sloping anteriorly to a 
small, rounded, median dorsal projection; postnotum scarcely 
developed, very short, not expanded at midline; mesosternum 
with posterior carina sharply angled laterally; wings long, ex- 
tending beyond apex of metasoma, anterior wing with marginal and 
submarginal cells approaching wing apex; first recurrent vein 
meeting second submarginal cell close to its apex; posterior wing 
with anal vein in an even curve, meeting discoidal vein beyond 
origin of cubitus; tibial spurs short, those at apex of posterior tibia 
of nearly equal length; anterior tibia without noticeable spines 
except short, slender spines at apex, without stout, curved spine at 
outer apex; posterior tibia smooth with unbroken dorsal carina 
extending nearly to apex; posterior basitarsi somewhat arched
