NO. 2 HONEY BEE — SNODGRASS IO9 



p/. First tcrgostcrnal muscle of the metathorax (fig. 21 F, G). — 

 Origin by broad base on metathoracic arm of endosternum, insertion 

 on anterior angle of lateral plate of metanotum (E). 



g8. Second tergosternal muscle of the metathorax (fig. 21 F, G). — 

 Origin on metathoracic endosternal arm posterior to p/, insertion on 

 posterior angle of lateral notal plate (E). 



QQ. Third tcrgostcrnal muscle of the metathorax (fig. 21 F). — At- 

 tached ventrally by narrowed end on small tongue (c) of metathoracic 

 arm of endosternum, fibers spreading dorsally to triangular lateral 

 area of metanotum. 



700. PI euro axillary muscle of the metathorax ; flexor of the hind 

 wing (fig. 21 B, H). — A small, three-part, fan-shaped muscle arising 

 on anterior marginal inflection of metapleuron, fibers converging to 

 small nodule in membrane of wing base (a) close to third axillary. 



loi. Basalar muscle of the metathorax (fig. 21 H). — A large muscle 

 arising by broad base on apodemal lobe of metathorax behind meso- 

 coxal cavity (fig. 16 H, r), inserted dorsally by a strong tendon on 

 basalar sclerite (fig. 21 B). 



102. Pleurosubalar muscle of the metathorax (fig. 21 C, H). — A 

 broad, thick, fan-shaped muscle arising on metapleuron, fibers con- 

 vergent to narrow insertion on subalar sclerite. (Not given by Mori- 

 son; two corresponding muscles in Vespida, Duncan.) 



10^. Lateral promotor of the hind coxa (fig. 24 A, B). — A fan- 

 shaped muscle arising on ridge between mesopleuron and propodeum, 

 the convergent fibers inserted laterally on anterior margin of coxa. 



104. Mesal promotor of the hind coxa (fig. 24 A, B). — Origin on 

 metasternal component of pterothoracic endosternum, insertion 

 mesally on anterior coxal margin. 



705. Lateral remotor of the hind coxa; coxosubalar muscle of the 

 metathorax (fig. 24 A, B). — A long muscle attached below on coxa 

 immediately behind pleural articulation, inserted dorsally by long 

 tendon on apodeme of subalar sclerite (fig. 21 B, C). Deflects the 

 wing posteriorly. (Wrongly said by Morison to arise on endo- 

 sternum.) 



106. Mesal remotor of the hind coxa (fig. 24 A, B). — Origin by 

 wide base on metasternal component of pterothoracic endosternum, 

 inserted by broad tendon in articular membrane close to posterior 

 mesal angle of base of coxa. 



707. Anterior levator of the hind trocJtanter (fig. 24 C, D). — Origin 

 anteriorly in coxa, insertion by tendon in dorsal membrane of coxo- 

 trochanteral joint beyond anterior coxal articulation (D).
