Answer

To answer the question "The basal segment of antenna is called," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Antennae Structure**:
- Antennae in insects, such as cockroaches, consist of multiple segments. Each antenna is made up of several parts that allow for movement and sensory functions.

2. **Identifying the Basal Segment**:
- The basal segment of the antenna is the first part that connects the antenna to the head. It is crucial for the articulation and movement of the antenna.

3. **Naming the Basal Segment**:
- The basal segment is specifically referred to as the "scape." This is the first segment of the antenna and is larger than the subsequent segments.

4. **Understanding Other Segments**:
- The second segment of the antenna is called the "pedicel." Following these two segments, the remaining parts of the antenna are referred to as the "flagellum."

5. **Conclusion**:
- Therefore, the correct answer to the question is that the basal segment of the antenna is called the "scape."

### Final Answer:
