of danielsi. 1 am especially grateful to the following private collec- 
tors for the opportunity of studying their specimens: Mr. Paul Harris, 
now of Mountain Home, Arkansas; Helen and Ted Piecko, Chicago; 
Mr. and Mrs. Francis Wolff, now of Port Charlotte, Florida; Mr. 
Daniel Damrow, Mosinee, Wisconsin; Mr. Raymond Bandringa, 
Willow Brook, Illinois; Mr. Joseph Pohl, Belgium, Wisconsin; and 
Mr. Richard Rock, Crest Hill, Illinois. As will become apparent from 
the account below, our present extensive knowledge of Eubleptus has 
resulted mainly from their fossil collecting and their cooperation in 
making the specimens available for study. 
1 am deeply indebted to the late Dr. Eugene S. Richardson, Jr., 
formerly of the Department of Geology, Field Museum of Natural 
History, for his unfailing cooperation and his assistance over the 
past fifteen years in the course of our investigations on the insects in 
the concretions from the Francis Creek Shale.*

Family Eubleptidae Handlirsch 
Eubleptidae Handlirsch, 1906a, p. 679; 1906b, p. 1 1 1.2 
Eubleptidae Laurentiaux, 1953, p. 423. 
Eubleptidae, Carpenter, 1965, p. 178. 
Small species, with slender, pointed wings. Fore wing; SC extend- 
ing nearly to wing apex, terminating on the costal margin; RS dichot- 
omously forked, with 4 (rarely 5) terminal branches; M forking just 
basad of the origin of RS; MA with a long fork; MP with 3 terminal 
branches; CUA with a short fork; CUP with 3 (rarely 2) terminal 
branches; 3 short anal veins present; relatively few cross veins, 
unbranched, and forming a distinct pattern; archedictyon absent. 
Hind wing: similar to the fore wing in venation but slightly broader 
near or before mid-wing, the hind margin strongly curved. Body: 
moderately slender; antennae very long and thin; head apparently 
'Shortly before his death in January, 1983, Dr. Richardson and I completed a joint 
paper on the Archaeognatha (Insecta) in the concretions. This will be published in 
the next issue of Psyche. 
2The family, genus, and species were described and designated as new in both of 
Handlirsch’s 1906 publications; the 1906a article obviously has priority, since ijiany 
of its pages are cited by number in the 1906b work.
