The forewings of individuals in the Euscelis genus are sprinkled with dark dots. Euscelis incisus is extremely variable in colour and markings, ranging from pale to blackish. Reliable separation of males from Euscelis lineolatus is best achieved by examining the genitalia, although the form of the abdominal markings on the final segments can be distinctive in females. The abdoment of Euscelis incisus females is entirely dark, whereas Euscelis lineolatus females can often be recognised by the pattern of three dark longitudinal stripes on the upperside of the tip of the abdomen.
