areolet is unusual though not unique in the Cryptine, that of 
Protocryptus Schmiedeknecht being very similar. In the Cryp- 
tine the completely defined areolet and areolated propodeum 
place it in the Phygadenonini, where it seems to me less dis- 
cordant than in any other placing. Here the narrow first tergite 
with spiracles placed in the middle is almost duplicated in — 
Thysiotorus Foerster as represented by 7. lamina (Thomson) and 
in Panargyrops Foerster. These two genera also have the biden- 
tate clypeus and the silky pubescence of the head; while in T. 
lamina the shape of the head and the relative length of the 
basal flagellar joints, though slenderer, are not very different. 
Except that the areolet is much broader and the stigma narrower 
with the radius originating near its base, the venation of the 
present genus differs in no essential particular from that of 
Panargyrops. If couplet 3 in Ashmead’s key to the Phy- 
gadenonini, the character in which can hardly be considered 
of generic value, be omitted, the genus runs to Panargyrops, 
though not agreeing with the last sentence. From either of » 
these genera it is at once distinguished by the structure of 
the propodeum, the compressed abdomen, and the shape of the 
areolet. 
Head from above strongly transverse with temples very nar- 
row; from in front very broadly transverse, subtriangular; eyes 
large, bulging, convergent below, malar space very short; clypeus 
separated by elevation, bidentate at apex, mandibles bidentate, 
upper tooth larger and longer; scape short, subglobose, flagellum 
tapering at apex, first joint much longer than second; entire 
body, including legs, and especially the head and thorax clothed 
with long, silvery hairs; pronotum short, polished, with lower 
angle foveolate, epomia fairly strong, sharply curved; meso- 
scutum flattened, polished, notauli obsolete, each lateral lobe 
with a deep, broad, longitudinal furrow, prescutum with two 
parallel shallow furrows; scutellum strongly convex, not mar- 
gined, basal fovea very broad and deep; postscutellum bifoveate 
at base; mesopleurum polished, wide in upper portion, prepectus 
broad below, ending above not far above ventral angle of pro- 
notum, sternauli broad and shallow and extending about half 
the length of mesopleurum, subalar tubercle carinate at top; 
propodeum short, sloping from base, completely areolated, the 
Intersections of the lateral carina with each of the transverse 
carine forming a prominent apophysis, the posterior one long 
and slender, the anterior one large and triangular in outline, 
embracing the entire basal abscissa of the lateral carina, and
