small in dorso-ventral view, but eyes prominent and protuding; 
beak well developed; prothorax short, with small and weak pronotal 
lobes; mesothorax and metathorax subequal; abdominal segments 
apparently with small lateral lobes; cerci very long; female with 
short, curved ovipositor. 
The family is known only from the Francis Creek Shale.

Fork of MA at nearly the same level as the first fork of RS; first 
fork of MP well before mid-wing, its posterior branch forked near 
the wing margin. 
Type-species: Eubleptus danielsi Handlirsch; by monotypy.

Fore wing: length 13-14 mm; maximum width, 3. 5-3. 8 mm; hind 
wing: length 13-14 mm; maximum width, 4-4.3 mm; length of 
antennae (complete), 1 1 mm. The venational pattern is shown in 
figure 2. Only slight individual variations seem to occur: RS usually 
with four terminal branches, but a fifth, short branch may be pres- 
ent; CUP usually with three branches, though the shortest one may 
be absent. Head about 3 mm wide across the eyes, and about 1.5 
mm long as seen from above (i.e., not including the beak, which is 3 
mm long). Pronotum about 1 mm long and 2.5 to 3 mm wide, 
including the small pronotal lobes; meso- and metathoracic seg- 
ments apparently subequal, although the compression of the body 
has probably altered the true proportions of both segments; the 
abdomen is about 13 mm long and 2 mm wide at mid-length. 
Holotype: no. 38731, U.S. National Museum of Natural History, 
Washington (L.E. Daniels, collector). This is a poorly preserved 
specimen, showing the proximal three-fourths of a fore wing and 
very little of the hind wings and body. Handlirsch described the 
species from both obverse and reverse halves, but when I examined
