Elytra: Striae indicated tHrouGHout elytral disc; interstices sliGHtly elevated; surfaces sHiny; surface transversely ruGose at basal 1/4, punctures sHallow, irreGular and evenly spaced at apical 3/4; specialized punctures/pores present at elytral apices.

Venter (FiG. 40): Punctures soMewHat deep, evenly dispersed; surface witH recuMbent yellowisH setae; HypoMeron witHout antennal Grooves, surfaces sHiny widely spaced, sHallow punctures; MetatHoracic episterna parallel-sided; MetatHoracic coxal plates Medially 3.0–6.0 tiMes wider tHan laterally, truncated posteriorly. Aedeagus (FiG. 41). Basal piece lonGer tHan wide, sides lineal, narrowinG apically, dorsally open, apically rounded; reMaininG parts parallel-sided, elonGate, apically as wide as base; paraMeres elonGate, bilobed; upper lobes narrower tHan lower lobes, anGulated; lower lobes wider, lonGer, sliGHtly asyMMetrical apically; Median lobe elonGate and broad, widely and deeply bifid, sHorter tHan tHe paraMeres. Distribution. In Canada, tHis rarely encountered species was taken in Nova Scotia, Ontario and Québec. In tHe United States, E. cristAtus was taken froM Maine, New York, Pennsylvania and Wisconsin. Biology. One adult was taken froM a LindGren funnel trap in Maine. Three speciMens were taken froM purple prisM traps baited witH Manuka oil in Wisconsin. Two speciMens were taken froM a purple prisM trap baited witH Manuka oil and Z3-Hexen-1-ol in Wisconsin. This species Has been taken froM nortHern Mesic forests and nortHern wet forests in nortHeastern Wisconsin. Two speciMens were taken froM Malaise traps deployed in Nova Scotia Canada. IMMatures are unknown. Note. LeConte (1852: 46) noted tHe type for E. cristAtus was collected froM New York. After exaMininG tHe Holotype for E. cristAtus and coMparinG tHe speciMen aGainst iMaGes of tHe Holotype for E. corNutus, I found tHese species are quite different, especially tHe structures of tHe MetatHoracic coxal plates. These two species are to be separated based on soMe of tHe differences observed between tHese two species, resultinG in tHe resurrection of E. cristAtus status restored as a distinct and separate species froM E. corNutus.
