Length 4.8 mm; estimated length of fore wing 2.5 mm. Colora- 
tion not preserved, specimen the color of amber. Scape barrel- 
shaped, about twice as long as wide; antennal segments 2-12 slightly 
longer than thick, 13 somewhat pointed, about 1.7 X as long as 
thick. Front femur 2.7 X as long as wide; segments of front tarsus 
in a ratio of 25:8:7:6:13, comparable measurements of hind tarsus 
45:18:14:8:13; front basitarsus with two minute lateral spines as 
well as some small apical ones; hind tibia with short spines as fig-

? FAMILY SCOLEBYTHIDAE 
Cretabythus, new genus 
Known from a single male approximately 2.5 mm in length, fully 
alate but with a reduced venation, hind wing without closed cells 
(Figs. 3, 4). Antennae elongate, 13-segmented, all segments some- 
what longer than wide; maxillary palpi elongate [probably 6-seg- 
mented] ; mandibles short, with 4 sharp apical teeth; clypeus, short, 
with a low median keel ; malar space short, about one fourth as long 
as width of mandibles at their base; eyes and ocelli of moderate size, 
ocelli in a broad triangle close to the broadly rounded vertex; head 
contracted immediately behind eyes; occipital carina complete. Pro- 
notum short, its posterior margin broadly arched between the pos- 
terior lobes, which are small, rounded, slightly below and touching 
the tegulae; pronotum with a short, anterior collar; notauli and 
parapsidal furrows complete; scutellum large, rather flat; base of 
propodeum with a slightly elevated, transverse band ( ?metanotum) ,. 
disc with a basal, semicircular area with strong surface sculpturing, 
otherwise smooth, with a strong transverse carina margining the 
abrupt, posterior declivity. Propleura well developed, somewhat 
prolonged anteriorly, but posternum and proepimeron (as described 
for Scolebythus ) not evident; mesopleura rather smooth, without 
evident pits, ridges, or sutures; front and hind coxae contiguous, 
middle coxae slightly separated. Fore wings as figured, with one
