The terrestrial Adephaga of Iowa (Part 1) by Fanny Chastina Thompson Wickham, 1895

The terrestrial Adephaga of Iowa by Fanny Chastina Thompson Wickham, 1895, Page 18

furnished with a few rigid hairs at the tips; terminal joint obtuse. Clypeus transverse, very short and contracted in the middle. 
The thorax subquadrate, sometimes cylindrical, rarely quadrate; the dorsal surface generally with an anterior and posterior impressed, transverse line connected by a longitudinal one giving to the disc a bilobate appearance. Prosternum narrow, not produced behind. Episternum and epimerum distinctly defined by sutures; coxae globular; coxal cavities entire. Merosternum truncate, the widest part extending forward, deeply emarginate behind. Merosternal epimera and episterna sometimes connate, without sutures, sometimes distinct. Metasternum pointed, both in front and behind, the epimera are large in winged species, small in wingless ones, while the episterna are small and often indistinct. Posterior coxae triangular, prominent internally, concave behind to allow of free motion. They do not extend to the sides of the body, but are inclosed by the metathorax and first ventral segment.
