64. The Fifth Lateral (cf. Fig. 22). The Homologue of 43. 

 The precoxale is not developed as a separate sclerite in the 

 metathorax, so this muscle has but two insertions, into the 

 trochantin and the coxa. [52]. 



65. The Sixth Lateral (Fig. 21). Homologue of 44. This 

 muscle is inserted quite distinctly into the coxa and not into 

 the epimeron as is the case in G. domesticus (Voss). Depressor 

 of the wing. [53]. 



(b) Noto-pleural. 



66. The Seventh Lateral (Fig. 21). Origin, from the 

 epimeron, a short distance dorsad of its middle; insertion, into 

 the posterior subalar plate. Depressor of the wing. [54]. 



67. The Twelfth Lateral (Fig. 21). The homologue of 

 48 q. V. 



68. The Eleventh Lateral (Fig. 21). From the anterior side 

 of the pleural wing process into the anterior angle of the base 

 of the wing, just in front of the anterior notal wing process. 

 Elevator of the wing. [58]. 



(c) Sterno-pleural. 



LXVIII. The Fiirca-entopleural Muscle of the Metathorax 

 {Not figured). Homologue of LI, q. v. 



STERNAL MUSCLES. 



Stemo-pedal. 



69. The First Pedal Muscle of the Metathorax (Fig. 20). 

 From the anterior side of the base of the entosternite into the 

 inner anterior edge of the coxa. Adductor and extensor of 

 the coxa. [60]. 



70. The Second Pedal Muscle (Fig. 20). Homologue of 53, 

 q. V. [61]. 



71. The Third Pedal Muscle (Fig. 21). Homologue of 54. 

 ;[62]. 



72. The Fifth Pedal Muscle (Fig. 21). Homologue of 

 55. [64]. 



LXXII. The Fourth Pedal Muscle (Not figured, cf. Fig. 

 21B, LV). Homologue of LV.
