Fig. 17. Chelopterum peregrinum Carpenter, 1950 (Grylloblattida: Protoperlina: Chelopteridae), originally described from Elmo: (A) Photograph of fore wing of a specimen collected by the authors from the Midco beds, scale bar 5 mm; (B) Original drawing by Beckemeyer based on reconstruction by Carpenter (1992); (C) Original drawing by Beckemeyer of the insect as it might have appeared in life, with wings folded.

Fig. 15. Relative distribution of the Wellington Formation species by type of body part(s) by which species are known.
Fig. 14 in The entomofauna of the Lower Permian fossil insect beds of Kansas and Oklahoma, USA
Fig. 14. Distribution of the Wellington Formation species by type of body part(s) for which species are known.
Fig. 13 in The entomofauna of the Lower Permian fossil insect beds of Kansas and Oklahoma, USA
Fig. 13. Adult-specimen abundance distributions of the Elmo entomofauna by major taxonomic groups. Taxa are arranged in order of groups with greatest to lowest species abundance.
Fig. 12 in The entomofauna of the Lower Permian fossil insect beds of Kansas and Oklahoma, USA
Fig. 12. Frequency distribution of adult-specimen abundance in 10-specimen size classes for the Elmo entomofauna.
Fig. 11 in The entomofauna of the Lower Permian fossil insect beds of Kansas and Oklahoma, USA
Fig. 11. Abundance of adult specimens of Elmo entomofauna. Values are plotted from species with fewest known specimens to species with the most known specimens. The species with the greatest numbers of specimens are identified.All labelled taxa are Grylloblattida except for D. tinctum (Psocoptera).
Fig. 10 in The entomofauna of the Lower Permian fossil insect beds of Kansas and Oklahoma, USA
Fig. 10. Size distributions of the Wellington Formation entomofauna by major taxonomic groups. Size is based on average forewing length in mm.
Fig. 8 in The entomofauna of the Lower Permian fossil insect beds of Kansas and Oklahoma, USA
Fig. 8. Distribution of size in the Wellington Formation entomofauna. Size is based on average forewing length in mm, plotted from smallest species to largest species. The 13 largest (forewing length>100 mm) and 2 smallest (forewing length <2 mm) species are identified. The two smallest species are both in the family Lophioneuridae. Ten of the largest species belong to the order Protodonata; M. grandis, to Palaeodictyoptera; G. carpenteri, to Caloneurodea; and S. ingens, to Megasecoptera.
Fig. 9 in The entomofauna of the Lower Permian fossil insect beds of Kansas and Oklahoma, USA
Fig. 9. Frequency distribution in 5-mm size classes of average forewing lengths for the Wellington Formation entomofauna.
Fig. 7 in The entomofauna of the Lower Permian fossil insect beds of Kansas and Oklahoma, USA
Fig. 7. Species diversity of the Wellington Formation entomofauna by Order (Suborder for the Grylloblattida). Orders are placed in three groups, Apterygota, Pterygota: Palaeoptera, and Pterygota: Neoptera, and are arranged in decreasing order of number of species. Bars show the number of species in each taxon unique to Elmo, unique to Midco and common to both. The nearly 200 species represent some 21 orders, 53 families and 106 genera.
Fig. 5 in The entomofauna of the Lower Permian fossil insect beds of Kansas and Oklahoma, USA
Fig. 5. Proportion of Wellington Formation entomofauna Neoptera and Palaeoptera subgroups unique to or shared between the Elmo and Midco localities, illustrating that the greater percentage of unique fauna at Elmo arises from the Neoptera. This reflects the fact that no review of the Neoptera from Midco has yet been published.
Fig. 6 in The entomofauna of the Lower Permian fossil insect beds of Kansas and Oklahoma, USA
Fig. 6. Comparison of the distribution of the Elmo Permian and World extant entomofaunas by major groups: Apterygota, Palaeoptera, Polyneoptera, Paraneoptera, and Holometabola.
Fig. 4 in The entomofauna of the Lower Permian fossil insect beds of Kansas and Oklahoma, USA
Fig. 4. (A) Gilbert O. Raasch (1903–1999) discovered the Midco fossil insect beds and documented the stratigraphy of the Oklahoma Wellington Formation in his PhD Thesis (Raasch 1946) (photo courtesy University of Wisconsin-Madison); (B) Paul Tasch of Wichita State University studied the palaeolimnology of the Wellington Formation in Kansas and Oklahoma and discovered additional Wellington Formation fossil insect localities in the late 1950's and early 1960's (photo courtesy of Wichita State University Department of Special Collections, Wichita, Kansas).
Fig. 3 in The entomofauna of the Lower Permian fossil insect beds of Kansas and Oklahoma, USA
Fig. 3. The settlement of Elmo, Kansas, as it appeared in the early 1900's. The fossil beds, located a few miles southeast, were named after the town. (Photo courtesy of the Wichita State University Libraries Department of Special Collections.)
Fig. 1 in The entomofauna of the Lower Permian fossil insect beds of Kansas and Oklahoma, USA
Fig. 1. Location and extent of the North American mid-continent Lower Permian Wellington Formation insect fossil deposits. The formation runs north to south some 270 km along eight counties, with major sites at the northern (Elmo, Kansas) and southern (Midco, Oklahoma) extremities.
