Answer

To solve the question about the plate situated between the eyes and passing below that on the head of a cockroach, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Anatomy of the Cockroach Head**:
- The head of a cockroach has several important structures including the eyes, ocelli (simple eyes), and various plates and sulci.

2. **Identify the Options**:
- The options provided are:
1. Vertex
2. Frons
3. Epicranium
4. Jena

3. **Analyze Each Option**:
- **Vertex**: This is the area above the eyes, not between them. Therefore, this option is incorrect.
- **Frons**: This is the area located between the compound eyes and below the ocelli. It is indeed the plate that lies between the eyes and passes below them. This option is likely correct.
- **Epicranium**: This refers to the exoskeleton of the head, which is not a plate situated between the eyes. Thus, this option is incorrect.
- **Jena**: This term refers to a structure found in the frontogenal sulcus, but it does not fit the description of being between the eyes and below them. Therefore, this option is also incorrect.

4. **Conclusion**:
- After analyzing all the options, the correct answer is **Frons** (Option 2), as it is the plate situated between the eyes and passing below them on the head of the cockroach.

### Final Answer:
The plate situated between the eyes and passing below that on the head of a cockroach is called the **Frons**.
