| They do not long persist in the embryo, but disappear, and the area each one occupied becomes part of the sternite. |
| A pair of dorso-ventral muscles passing from tergite to sternite in each segment. |
| Burke interpreted the ventral sclerite as being solely comprised of the sternite fused with the coxae. |
| These muscles are arranged as a series of parallel muscle fibers from the lateral edge of the dorsal tergite to the ventral sternite. |
| These elements are a central piece or sternite, and a lateral field on each side bearing the leg-rudiment. |
| A faint transversal line may indicate the posterior border of the seventh sternite. |
