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. **Identify the Structure**: We need to find the specific structure located between the eyes of the cockroach. The question specifies that it is a plate that passes below the eyes.

2. **Understand Cockroach Anatomy**: In the anatomy of a cockroach, there are several key structures around the head, including the compound eyes and simple eyes. The area we are interested in is located between these eyes.

3. **Locate the Frons**: The structure that fits the description of being situated between the eyes and passing below them is called the "frons." This is a specific part of the head in insects.

4. **Differentiate from Other Structures**:
- **Vertex**: This is located above the frons and is not the correct answer.
- **Epicranium**: This refers to the outer exoskeleton of the head, which is also not the correct answer.
- **Gena**: This refers to the sides of the head, which again does not fit the description provided in the question.

5. **Conclusion**: Based on the anatomical features of the cockroach, the correct answer to the question is "frons."
