Psyche 
[April 
tooth very large, occupying about two-thirds of the inferior 
margin of the mandible, the outer margin of the tooth long, the 
inner margin from the apex of the tooth to the base of the man- 
dible much shorter, fringed with short yellowish pubescence, 
the apex being submedian with reference to the upper surface 
of the mandible; cheeks fairly broad, shining, finely punctured, 
the punctures close below, well separated above, lower angle 
with a rather small bare concavity, but with a robust tooth 
which is densely pubescent on the apex; vertex slightly rounded, 
closely and quite finely punctured, the punctures deep, pubes- 
cence long and erect, much thinner than on face; lateral ocelli 
about equally distant from eyes and edge of vertex; antennae 
piceous above, somewhat paler below, rather short, the middle 
joints but slightly longer than broad, the apical one flattened 
and considerably dilated. 
Thorax with pubescence entirely pale, ochraceous above 
fading to white below, quite long and dense on mesonotum, but 
not hiding the surface which is deeply and closely punctured 
throughout; scutellum closely and rather more finely punctured 
pleura also finely and closely punctured; mesosternum concave, 
shining, almost impunctate, with two anterior, broad, trans- 
versely flattened spines which are rounded apically, one behind 
each front coxa; propodeum finely punctate, with long, rather 
dense pale pubescence; tegulae pale ferruginous, finely and rather 
closely punctured, pubescent anteriorly; wings subhyaline, 
clouded apically, nervures brownish, basal nervure slightly be- 
yond transverse median, second recurrent nervure entering 
second submarginal cell nearer apex than first does to base. 
Legs black to piceous, pubescence white, pale yellowish on 
four posterior tarsi beneath; front coxae broad, bare, polished, 
with long, very broad and much flattened spatula-like spines, 
these incurved on inner apex, the apex narrowed and rounded, 
no red bristles on the coxae, the spines long white pubescent 
behind; anterior femora very strongly keeled, the posterior face 
being very wide, dark, rather closely and finely punctate, but 
nearly bare of pubescence, upper face also dark, the antero- 
inferior face polished testaceous, ferruginous basally and along 
upper margin; outer face of front tibiae dark, punctate and white
