FAMILY BETHYLIDAE 
Archaepyris, new genus 
Wasps approximately 2 mm in length, fully alate, of fuscous 
coloration (known only from males) (Figs. 12, 15). Antennae 
simple, with 13 segments; eyes large, slightly protruding from sides 
of head, not noticeably hairy; mandibles short, broad, with several 
sharp apical teeth ; clypeus short, median lobe only slightly produced ; 
ocelli of moderate size, situated close to vertex crest. Pronotum 
moderately long, disc only slightly shorter than mesoscutum along 
midline; notauli and basal scutellar pits or groove not visible; pro- 
podeum short, with a more or less flat dorsal surface that is slightly 
wider than long, also with an almost vertical posterior declivity. 
Legs not spinose ; claws weakly dentate. Fore wing as figured, with 
a short vein arising from basal vein, the discoidal cell outlined by 
weak veins and outer part of wing with a series of fine creases that 
may mark the course of former veins. Metasoma sessile. 
Type-species. — Archaepyris minutus, new species. 
Remarks. — Since the classification of Bethylidae is based on struc- 
tural minutiae that require perfect preservation and close study under 
high power, placement of fossil material involves a large measure of 
guess work. Archaepyris I would judge to be a very generalized 
bethylid, combining features of the usually recognized subfamilies. 
Although Epyris-Wke in general form, the venation is suggestive of 
some Pristocerinae, while the vein arising from the basal vein sug- 
gests Bethylinae. 
Archaepyris minutus, new species 
Length 2 mm; fore wing 1.4 mm. Fuscous; wings hyaline, with 
brown veins and stigma. Front slightly narrower than eye height, 
with a weak median groove; sculpturing of front rather weak; 
antennae arising close to base of clypeus, the segments in the follow- 
ing ratio: 15:10:9:10:9:9:9:9:9:9:9:9:15. Segments of middle tar- 
sus in the following ratio: 16:7:7:5:9. Subgenital plate simple; 
parameres hirsute, somewhat rounded apically.
