specimens. Body slender, gently depressed; head evenly 
convex dorsally, in lateral view suboval, with subtruncate 
posterior end. Eyes long-oval, with 10-12 coarse facets 
arranged in a double row, plus a very few other less well- 
developed facets. Sides of head gently convex, subparallel 
(see figure). Mandibles largely hidden when head is 
viewed from dorsal side ; dentition as in figure 3. Maxillary 
palpi not clearly visible, but apparently much as described 
for lucidus. Labial palpi not visible. Alitrunk slightly 
depressed dorsally, in profile the dorsal outline nearly per- 
fectly straight. Legs gently incrassate, profemora more 
strongly so. 
Dorsum and sides of head covered with small, densely 
arranged, umbilicate-piligerous foveolae, contiguous and 
subcontiguous on most of the sides and dorsum, but thin- 
ning out slightly in the extreme median dorsal region, 
where a very restricted area shows some “Scotch grain” 
coriaceous sculpture and is feebly shining. The greater 
part of the head is opaque. Alitrunk rather strongly and 
densely coriaceous, subopaque to opaque, with a few indis- 
tinct punctures. Mesonoto-scutellar sutural line moder- 
ately distinct. Propodeum feebly subrugulose in addition 
to the ground sculpture. Gaster smooth and shining. Legs, 
scapes and mandibles very feebly and finely punctulate- 
granulose, weakly to moderately shining. 
Pilosity consisting of fine, tapered hairs, rather abund- 
ant and erect or suberect, but more nearly reclinate on 
the appendages, short to moderate in length and distributed 
rather evenly over the body. Color deep yellowish-fer- 
rugineous; gaster brown, shading off to ferrugineous at 
both basal and apical extremities; legs and antennae clear 
yellow.
