110 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. IO3 



108. Posterior levator of the hind trochanter (fig. 24 C, D). — 

 Origin posteriorly in coxa, insertion in dorsal membrane of coxo- 

 trochanteral joint beyond posterior coxal articulation (D). 



log. Thoracic depressor of the hind trochanter (fig. 24 A, C). — 

 Origin on metathoracic arm of pterothoracic endosternum (A), 

 fibers convergent into coxa to insertion on long depressor apodeme 

 of trochanter (D, Ap). 



no. Coxal depressor of the hind trochanter (fig. 24 C, E). — A 

 broad muscle arising ventrally in coxa, the convergent fibers inserted 

 on base of depressor apodeme of trochanter (E). 



///. Reductor of the hind femur (fig. 24 C). — A short thick 

 muscle arising anterodorsally in trochanter, inserted ventroposteriorly 

 on apodemal inflection of base of trochanter (F, Ap). 



J 1 2. Extensor of the hind tibia (fig. 24 H). — A long pinnate 

 muscle arising along dorsal wall of femur, inserted by tendon on 

 dorsal knob of base of tibia. 



77J. Flexor of the hind tibia (fig. 24 H). — A large pinnate muscle 

 lying in ventral half of tibia, fibers attached anteriorly and posteriorly, 

 inserted by strong axial tendon on ventral genuflexor plate at base 

 of tibia (G, H, gf). 



114. Promotor of the hind tarsus (fig. 24 J, K, L). — Origin ven- 

 trally on anterior wall of wide distal part of tibia (K, L), inserted 

 anteriorly on base of tarsus (J). 



7/5. Levator of the hind tarsus (fig. 24 J, K, L). — A fan-shaped 

 muscle arising on posterior wall of distal part of tibia (K), inserted 

 posteriorly by narrow stalk on base of tarsus but above level of tibial 

 articulation (/). Corresponds with the reductor of the other legs. 



77(5. Depressor of the hind tarsus (fig. 24 J, K, L). — Much larger 

 than the other two tarsal muscles, arises on anterior wall of tibia (K), 

 inserted ventrally on base of tarsus (J, L). 



777. Flexor of the pretarsal clazvs of the hind leg (fig. 24 H, K). — • 

 As in the other legs, a two-branched muscle, one branch arising 

 posteriorly in base of femur (H, 117a), the other posteriorly in base 

 of tibia (K, iiyb), both branches inserted on long apodemal tendon 

 extending through tarsus and tibia into femur from its origin in 

 articular membrane at base of unguitractor plate of pretarsus, as in 

 middle leg (fig. 25 B, pjAp). 



118. Median intersegmental ventral muscle of the metathorax; 

 median depressor of the abdomen (fig. 27 E). — A long muscle aris- 

 ing anteriorly on metasternal component of pterothoracic endosternum, 

 inserted posteriorly by broad tendon medially on sternum of petiole 

 segment (IIS).
