tion; wing membrane usually dark, with light bands and spots. Fore 
wings resembling hind wings in outline but with broader subcostal 
area. Anterior margin nearly straight, often with precostal strip ; 
stems of main veins convex in the basal third, as in Homoiopteridae ; 
Sc long; MA simple, curved, originating near the first fork of MP; 
MP with many branches, occupying a markedly triangular area; 
CuA simple and curved ; CuP parallel to CuA, but with several 
branches. Anal area often large, with many branches. Cross veins 
fine, numerous, more or less irregular, sometimes connected. 
Body structures: head small with conspicuous eyes and large 
clypeus. Prothoracic lobes with fan-like veins and many cross veins, 
often with undulated margins. Thorax broad, metathorax shorter 
than mesothorax; legs homonomous, not very short. Ovipositor not 
sculptured, stout and curved. Cerci robust, long. 
The family Lycocercidae is related to the Homoiopteridae in 
the characteristic curvature of stems of main veins near the base, 
in the late division of M, in the general character of cross veins, in 
the presence of many small forks along the posterior margin, etc. 
It differs from the Homoiopteridae in the narrowed hind wing and 
more richly branched MP and CuP and simple CuA. Another 
related family is the Graphiptilidae, from which the Lycocercidae 
differ in the richly branched MP and CuP and the narrower hind 
wings. 
Genera included in the Commentry shales: Lycocercus Handlirsch 
and Apopappus Handlirsch. 
Occurrence in other deposits: Lycocercus Handlirsch, Namurian 
B, Germany. 
Genus Lycocercus Handlirsch 
Lycocercus Handlirsch, 1906: 89, Handlirsch, 1919: 15; Lameere, 1917: 153. 
Patteiskya Laurentiaux, 1958: 302; Demoulin, 1958: 360. 
Type species: Dictyoneura goldenbergi Brongniart, 1893 (SD 
Handlirsch, 1922). 
This genus was erected by Handlirsch for goldenbergi Brongniart, 
as represented by specimen 21-1. Specimen 21-2, correctly described 
by Brongniart under the same specific name, was erroneously re- 
ferred by Handlirsch (1906, p. 90) to a separate species brongniarti 
(Lameere, 1917, p. 153). Meunier (1911, p. 12 1) described Homoi- 
optera brongniarti , which Handlirsch later (1919, p. 15) recognized 
as Lycocercus. The specific name having been preoccupied within 
the genus since 1906, Handlirsch (1919, p. 16) changed it to 
Lycocercus pictus. Though Lameere (1917, p. 153) believed that 
pictus was conspecific with goldenbergi , he was apparently incorrect.
