Genus 4.— Tomopygia, Burr. 
This genus was erected by me in 1904, p. 287, for the 
curious creature from Java described by de Bormans 
under the name Cylindrogaster abnormis. It is undoubtedly 
allied to Labidura and Paralabidura, but the abbreviated 
elytra, broad short scutellum, small, square pronotum and 
exceedingly long and slender legs, are all strong characters.
