To solve the question "In cockroach, cuticle is not found in lining of," we need to analyze the structure of the cockroach's alimentary canal and identify where the cuticle is absent. Here’s a step-by-step breakdown of the solution:

### Step-by-Step Solution:

1. **Understand the Structure of the Cockroach's Alimentary Canal**:
- The alimentary canal of a cockroach is divided into three main regions: foregut, midgut, and hindgut.

2. **Identify the Regions**:
- **Foregut**: This includes the mouth, pharynx, esophagus, crop, and gizzard. The foregut is lined with cuticle.
- **Midgut**: This is the region where digestion and absorption occur. It is lined with a special membrane.
- **Hindgut**: This includes the ileum, colon, and rectum. The hindgut is also lined with cuticle.

3. **Focus on the Midgut**:
- The midgut is unique because it is not lined with cuticle. Instead, it is lined with a peritrophic membrane, which serves different functions compared to the cuticle.

4. **Conclusion**:
- Therefore, the correct answer to the question is that the cuticle is not found in the lining of the **midgut** of the cockroach.
