The Employee State Insurance Corporation (ESIC) provides healthcare and insurance benefits to employees in India. If you're asking about the eligibility for senior citizens or older females seeking outpatient (OP) services in the afternoon at ESIC, the following points may be relevant:

1. Senior Citizens Definition: Generally, in India, a senior citizen is defined as someone who is 60 years of age or older. For females, the same age criteria apply.
   
2. ESIC Benefits: ESIC benefits are typically available to employees who are covered under the scheme, as well as their dependents, including spouses and children. Retired employees who meet certain criteria may also continue to receive benefits.
   
3. Age Limit: For outpatient services specifically related to senior citizens, there may not be a strict age limit beyond the standard senior citizen definition (60+ years). However, certain services and facilities may be tailored specifically for older adults.
   
4. Afternoon OP Services: The availability of afternoon outpatient services can vary depending on the specific ESIC hospital or dispensary. Some facilities may offer dedicated time slots for senior citizens, but this would need to be confirmed with the specific ESIC center.
   
5. If you have a specific ESIC center or facility in mind, it may be helpful to contact them directly for detailed information about the services offered to senior female patients.
