46. The Fourteenth Lateral Muscle (Fig. 21 B). From the 

 precoxale into the basalar sclerite by the same tendon as 38. 

 Found only in the male. Elevator of the tegmen. [91]. 



LI. The Furca-entopleural Muscle (not figured). From the 

 inner sides of the entosternal pocket into the ventral process of 

 the entopleurite. Binds the two processes together. [100]. 



STERNAL MUSCLES. 



Sterno-pedal. 



52. The First Pedal Muscle of the Mesothorax (Fig. 21). 

 Origin, by three heads from (1) the base of the entosternite, 

 (2 and 3) , the sternum immediately in front of the entosternite ; 

 insertion into the anterior edge of the coxa. Extensor of the 

 coxa. [93]. 



LII. The Seventh Pedal Muscle (Fig. 21). From the 

 median entosternite, into the posterior edge of the coxa. Flexor 

 of the coxa. [99]. 



53. The Second Pedal Muscle (Fig. 20). From the lateral 

 entosternite above the inner angle of the leg into the posterior 

 edge of the leg adjacent to the insertion of 39. Flexor of the 

 coxa. [94]. 



54. The Third Pedal Muscle (Fig. 21). From the posterior 

 edge of the entosternal pocket into the meso-caudal side of the 

 edge of the coxa. Flexor and adductor of the coxa. [95]. 



55. The Fifth Pedal Muscle (Fig. 21). From the posterior 

 edge of the distal end of the entosternite into the postero- 

 lateral border of the coxa. Adductor of the coxa. [97]. 



LV. The Fourth Pedal Muscle (Fig. 21 B). From the 

 entosternite near the origin of 54, into the trochanter by the 

 same tendon as 40. Extensor of the femur. [96]. 



C. The Metathorax. 



LONGITUDINAL MUSCLES. 



(a) Sternal. 



LVI. The First Metasternal Muscle (Figs. 20 and 32). 

 Originates from the posterior side of the base of the entosternite 

 near the median line and runs backwards above the first four 

 abdominal sternites. It has three insertions into the lateral 

 end of the anterior edge of the third, fourth and fifth sternites 

 respectively. A ventral retractor of the abdomen. [34].
