Psyche 
[September 
with a copious, white fringe. Antennae short, clavate, 
black with the under side of the flagellum slightly tinged 
with brownish, joint 3 slightly longer than 2 or 4, 
which are subequal, the proportion of joints 2-5 being 
4.5 :5 :4.5 :4.5, the median flagellar joints one-sixth shorter 
than wide (5x6). Prothoracic spines very short but sharp, 
entirely concealed in the pubescence. Mesoscutum with 
rather coarse but not very deep punctures, separated the 
width of one or almost so anteriorly and laterally, on the 
posterior disk a distinctly defined, rather large, polished 
and impunctate area, the parapsidal furrows also bounded 
by impunctate lines. Mesoscutellum basally and medially 
polished and impunctate, laterally coarsely and rather 
closely punctured, the punctures crowded along the apical 
margin. Metanotum roughened by coarse, shallow, can- 
cellate punctures. Superior face of the propodeum very 
broad and well defined, its apical margin strongly rimmed, 
divided by a few straight strise into a few large, rectangu- 
lar, shiny pits nearly as wide as long medially. Enclosure 
on the posterior face of the propodeum funnel-shaped, 
mostly smooth and polished, a few oblique striae at extreme 
sides basally and indications of a short, basal median carina, 
the downward prolongation moderately broad at base. Sur- 
rounding areas of propodeum shiny, very coarsely reticu- 
lated. Mesopleura with coarse, round punctures about like 
those on mesoscutum anteriorly. Pubescence of mesopleura 
discally long, thin, erect, plumose and black, forming two 
longer and denser black tufts under and before the tegulse, 
the space between these tufts with a contrasting, shorter, 
finely plumose, almost pollinose, snowy white hair-tuft, 
the mesoscutum with a short, plumose, mixed black and 
grayish white pubescence that is rather dense marginally 
but very thin discally, the pale hairs preponderating and 
forming an unmixed fringe along proscutal-mesoscutal 
suture, the mesoscutellum with copious, long, wholly black, 
plumose hairs with a contrasting snowy white axillary tuft 
of short hairs and a narrow fringe of similar hairs in the 
mesoscutal-mesoscutellar suture, the metanotum and pro- 
podeum with long, copious, erect, plumose, grayish white 
hairs, these very thinly mixed with dark ones on the sides 
of the posterior face of the propodeum. Tegulse shining
