abdomen and also on the tibiae. Head very slightly wider than high 
(Fig. i). Clypeus with a broad but very short median lobe, the 
margin of which is slightly concave, paralleled by a series of setae. 
Front slightly alutaceous, with many very small punctures, barely 
impressed medially. Minimum distance between eyes 1.15 X height 
of an eye; inner orbits closest near the middle, weakly divergent above, 
strongly divergent below. Posterior ocelli situated on an imaginary 
line drawn between eye tops; width of ocellar triangle (including 
ocelli) 1. 1 5 X ocello-ocular line; distance from posterior ocelli to 
occipital carina 1.5 X width of ocellar triangle. Basal enclosure of 
propodeum much longer than metanotum, its posterior margin obtusely 
angulate ; enclosure as well as main part of propodeum with a median 
groove, especially strong behind. Front femora 2.7 X as long as wide; 
hind femora longer and somewhat more compressed, but of about the 
same proportions. Wings as shown in Fig. 2. 
Remarks. — This species is known only from the type. 
Genus Clystopsenella Kieffer 
Clystopsenella Kieffer, 1911, Ann. Soc. Sci. Bruxelles, 3 5 : 204. 
Kieffer, 1914, Das Tierreich, 41 : 555-556. 
Type species: C. longiventris Kieffer, monobasic. 
Kieffer included Clystopsenella in the subfamily Bethylinae of the 
Bethylidae, and in fact the wings do bear much resemblance to those 
of certain genera of that subfamily, especially Eupsenella. However, 
in virtually every respect Clystopsenella departs radically in structure 
from the Bethylinae, in fact from all Bethylidae, as discussed further 
below.

Description. — Length 7 mm. ; fore wing 4 mm. Head testaceous, 
the vertex with three brownish streaks, one starting at the ocellar tri- 
angle and one at the upper end of each eye, all extending backward 
but not extending over the top of the vertex; mandibles testaceous, 
the teeth dark; first two antennal segments light brown, rest of 
antenna dark brown. Thorax wholly testaceous to pale castaneous, 
slightly darker on anterior face of pronotum, sides of mesoscutum, 
metanotum, pleura, and venter; legs wholly testaceous; abdomen pale 
castaneous, each segment with an indistinct paler apical band. Wings 
hyaline, weakly tinged with brownish along the veins, the veins and
