Egg. General shape oblong, cross-section concave ( Figs. 1‒2 View Figs ), anterior and posterior poles broadly-rounded ( Figs. 2‒4 View Figs ). Color pale brown. Collar well-developed, with irregular longitudinal ridges, slightly flared apically ( Fig. 3 View Figs ). Follicle cell impressions near collar ranging from elongate to hexagonal ( Figs. 1, 3 View Figs ). Chorion covered mostly with irregular-shaped pentagonal or hexagonal follicle cell impressions with thickened elevated ridges ( Figs. 4‒6 View Figs ); floors with numerous shallow pits ( Fig. 5‒6 View Figs ). Eclosion line present ( Figs. 4‒6 View Figs ). Micropyles located along ridges near eclosion line in anterior ¼ ( Figs. 5‒6 View Figs ).

Diagnosis. Szczytko & Kondratieff (2015) placed this species in the I. burksi group with I. cotta Ricker, 1952 and I. orata Frison, 1942 . Egg characteristics uniting these species include a concave crosssection, well-developed collar, distinct ridges offsetting the cell impressions, and lack of an eclosion line ( Szczytko & Kondratieff 2015). Eggs of I. burksi from Indiana and Kentucky, however, possess a distinct eclosion line ( Figs. 4‒6 View Figs ) that easily distinguishes this species from I. cotta ( Szczytko & Kondratieff 2015, figs. 10.14, 10.18) and I. orata ( Szczytko & Kondratieff 2015, figs. 37.9, 37.12). Each of the other three characteristics listed above are exhibited by I. burksi .
