Answer

To solve the question "In cockroach, cuticle is not found in lining of," we will follow these steps:

### Step 1: Understand the Structure of the Cockroach's Elementary Canal
The cockroach's elementary canal can be divided into three main parts:
- **Foregut**: This includes the preoral cavity, mouth, pharynx, esophagus, crop, and gizzard.
- **Midgut**: This is the central part of the canal, which is a thin-walled, coiled tube.
- **Hindgut**: This includes the ileum, colon, rectum, and anus.

### Step 2: Identify the Role of the Cuticle
The cuticle is a protective layer found in the body wall of arthropods, including cockroaches. It serves various functions such as protection and prevention of water loss.

### Step 3: Determine Where the Cuticle is Present
- The **Foregut** is lined with cuticle throughout its entire structure.
- The **Hindgut** is also lined with cuticle on all sides.
- The **Midgut**, however, is not lined with cuticle. It is a thin-walled structure that does not have this protective layer.

### Step 4: Conclude the Answer
Based on the above analysis, the part of the cockroach's elementary canal that does not have a cuticular lining is the **Midgut**.

### Final Answer
The cuticle is not found in the lining of the **Midgut** of the cockroach.
