to inferior cunea behind; PI pleura! lobe; PN pronotum; pn-est.stl 

 abdominal muscles from eusterno-sternellar line to posterior notch behind; 

 PnF postnotal fold behind prothorax; pn-sc muscles denning scutal 

 plate or scutum from posterior notch to scutal line; pn-st muscle from 

 sternal line to posterior notch behind; PoCx postcoxal area; PrSc pre- 

 scutum; PrSt presternum; PrTg protergum; PrTh Prothorax; p.s 

 pleural suture; p.sc line defining posterior boundary of scutal plate; 

 ps-i abdominal muscle from posterior line of prescutum to inferior cunea 

 behind. This muscle is only present in one subfamily of Cerambycidae; 

 S sternum; Sc scutum of thorax and scutal plate of abdomen; s.c 

 scutal line, defining lateral limit of abdominal scutal plate and thoracic 

 scutum. This line in the thorax is the same as the abdominal parascutal 

 line; sc-cx muscles from scutal line to posterior point of coxa; sc-cx-st 

 muscles from scutum to anterior ventral point of coxa near sternal line; 

 Scl scutellum; sc-sp thoracic muscle from scutual line to sternopleural 

 suture; s.p. sternopleural suture; SpA spiracular area; sp-c prothorac 

 muscle from sternopleural suture to ventral boundary of coxa; s-pcx 

 muscles from post coxal line to superior cunea behind; spi-pn muscles 

 from posterior notch to spiracle; s-pn 1 lower band of muscles from pos- 

 terior notch to superior cunea in front ; s-pn- upper band of muscles from 

 posterior notch to superior cunea in front; sp-t thoracic muscle from sterno- 

 pleural suture to trochanter; *->/ superior retractor muscles of head; 

 s-sc muscle of the Prioninae from the scutal line to superior cunea in 

 front also muscles from the anterior and posterior boundaries of scutal 

 plate to superior cunea; s-sp thoracic muscle from sternopleural suture 

 or occasionally posterior boundary of presternum line to superior cunea 

 in front or rarely behind (Plate 8 dotted muscle); s-s-sp first abdominal 

 muscle from posterior notch of second segment across first to superior 

 cunea a continuation of muscle s-pn 1 , s-st several muscles from superior 

 cunea to a point in front of post coxal area. They may be considered as 

 forming the anterior limit of this area or a continuation of sternal line as 

 found in the clerids; s.t sternal line perpendicular to eusternal-sternellar 

 line; Stl sternellum; T tergum; t.p tergopleural suture; tp-cx muscle 

 from tergopleural suture to posterior point of coxa; tp-pcx muscle from 

 tergopleural suture to postcoxal line; tp-pn abdominal muscles from 

 posterior notch to tergopleural suture; tp-pn 1 thoracic muscles homol- 

 ogous to tp-pn; tp-pn 2 thoracic muscles on posterior half of segment 

 from tergopleural suture to posterior notch. These two sets pull down 

 the alar area; tp-sp muscles between tergopleural and sternopleural 

 sutures; Ip-st muscles from tergopleural suture to sternal line; x 

 appodeme on sternopleural suture; xx appodeme on eusterno-sternellai 

 line.
