NOCTUID METATHORAX — TREAT 371 



pvr Plates 7, 8, 14, 15. A flat, narrow, ligamentous band from 



the ventral portion of the pleural ridge to the base of the 

 posterior furcal arm. Muscular chiefly at its furcal end, and 

 withstanding treatment with KOH. 



Sternopedal muscles 



sti Plates 10, 12. A broad, short fan converging sharply from 



the ventral median plate of the sternum to the anteromedial 



angle of the coxa just anteroventral to the insertion of dv^. 

 stz Plates 8, 10, 12. A broad fan from the anterior part of the 



median ridge of the furca to the median (depressor) tendon 



of the trochanter, 

 stg Plates 7, 8, 10, 12. A small bundle from the median ridge 



of the furca to the posteroventral portion of the merocosta. 

 sti Plates 7, 8, 13. A thin, broad fan diverging from the median 



ridge of the furca laterally to the merocosta. Absent in Telea 



according to Niiesch. 



Coxal muscles 



cxi Plates 7, 8, 12, 13. A broad, spoonlike fan converging from 



the anterior and medial surfaces of the basicosta to a tendon 

 inserting on the anterior lip of the trochanteral groove. 



CX2 Plates 13, 14. A thick, funnel-shaped muscle converging 



from beneath the lateral portion of the basicosta to a tendon 

 plate in the lateral articular membrane of the trochanter, 

 which it elevates. 



CX3 Plates 6, 7, 8, 12, 13. A short, conical muscle converging 



from the posteromedial portion of the basicosta to a tendon 

 inserting near the base of a tubercle on the posteromedial 

 edge of the trochanter, which it elevates. 



Spiracular muscles 



sd Not found in Crymodcs. 



so Plate 8. A small bundle from the postcoxal bridge of the 



mesothorax to the ventral border of the anterior lip of the 



spiracle. 



MESOTHORACIC AND ABDOMINAL MUSCLES 



Ildli Plate 10. The median longitudinal dorsal muscle of the 

 mesothorax.
