Psyche 
[March 
exceedingly short, extending beyond the antennal sockets by less than 
the diameter of the latter; median basal portion of clypeus extending 
triangularly upward between the antennal sockets, nearly reaching the 
level of the top of the sockets (5). Face depressed laterad of each 
antennal socket for reception of the scape. Rims of antennal sockets 
slightly raised on upper side, the sockets opening obliquely downward, 
not overhung by ridges (6). Antennae with thirteen segments (7) ; 
scape much flattened, slightly curved ; flagellum simple, covered with 
short, suberect setulae. Malar space well developed, at least a third as 
long as width of mandibles at their base. Ocellar triangle at or slightly 
below level of tops of eyes, vertex rounded off well above ocelli and 
eye tops; occipital carina present or absent. Pronotum short, with a 
short dorsal surface and a strong, nearly vertical anterior face, but the 
collar virtually absent, revealing an open, membranous space between 
the tops of the propleura (8) ; posterior lateral lobes of pronotum 
somewhat rounded, touching the tegulae. Proepisterna very large, 
produced strongly forward so that the head is well separated from the 
pronotum (9). Proepimera present at base of front coxae, completely 
set off by sutures from the proepisterna ( 10) . Prosternum remarkably 
large (more than half as long along midline as length of front femur), 
diamond shaped, the entire venter of the prothorax forming a large 
flat surface with a Y-shaped suture (the suture separating the pros- 
ternum from the proepisterna) (11). Front coxae flattened, com- 
pressed against the sternum (12). Mesosternal region large and 
somewhat flattened ; mesosternum simple, not produced backward over 
middle coxae (13). Middle coxae separated by an elevated median 
ridge of the metasternal region ( 14) , these coxae also slightly flattened. 
Hind coxae contiguous, their sockets not separated by any sclerotized 
parts. Mesoscutum with both notauli and parapsidal grooves nearly 
complete; scutellum at the base with a pair of widely separated, trans- 
verse pits. Metanotum a narrow transverse band, sometimes concealed 
medially by the scutellum. Propodeum with a basal transverse area 
which is longer on the midline than the metanotum and which is set 
off from the remainder of the propodeum by a strong suture (15) ; 
propodeal disc with the slope low and even, without sculpturing or a 
strong posterior rim. Mesopleura large and convex, without sculptur- 
ing except for a vertical suture passing downward from the posterior 
lobes of the pronotum, marking off a small epicnemium (16). All 
femora moderately broadened and compressed ; legs completely without 
spines but bearing some unusually long setae ( 17) . Tibial spurs 1-2-2. 
Claws slender, simple except subdentate basally ( 18) . Fore wing with 
a stigma and a closed marginal cell, also with one submarginal cell and
