92. The Second Lateral (Fig. 32). From the parasternal 

 plate into the antero-ventral edge of the third pleural sclerite 

 of the third segment. [24, sixth lateral parastigmatal]. 



93. The Third Lateral (Fig. 32). From the parasternite 

 into the second pleural sclerite of the second segment. 



C. The Third to 'Sixth Segments of the Female; 

 Third to Eighth of the Male. 



TRANSVERSE MUSCLES. 



Sternal. 



94. The Transverse Ventral Muscle (Fig. 32) lies entirely 

 within the sternum across the anterior end. Its points of 

 attachment are near the latero-anterior angles of the sternite. 



LONGITUDINAL MUSCLES. 



(a) Sternal. 



95. The First Ventral Muscle (Fig. 32). A short muscle 

 having its origin near the transverse median line and lying not 

 far from the longitudinal median line of the sternite. It is 

 inserted into the anterior border of the segment behind the 

 one in which it lies. [1]. 



96. The Second Ventral Muscle (Fig. 32) lies in the lateral 

 side of the sternum and extends from the anterior border of 

 one segment to the anterior border of the next segment behind. 

 [2]. 



(b) Dorsal. 



83, 84. The First and Second Dorsals. (See above). 



DORSOVENTRAL MUSCLES. 



Tergo-stemal. 



97. The First Dorsoventral Muscle (Fig. 32) stretches across 

 the pleural membrane from the antero-lateral angle of the 

 tergite to the corresponding region of the sternite. Homologue 

 of 85. 



98. The Dorsoventral Sternal (Fig. 32). Homologue of 77 

 and 86. Similar to 97, but lying in the posterior end of the 

 segment. [5].
