Episternum (ES") — Episternum (Audouin, '24). 

 = Parapleura (Burmeister, '32). 

 = Pleura (Kirby, '28). . 

 = Coxopleure (Verhoeff, '03) in Forficula. In the Blattidae, Verhoeff's 



coxopleure is the episternum plus the anterior laterale. 

 Comstock's, '02, and Walton's, '00, episternum in the Blattidae is the epi- 

 sternum plus the anterior laterale. 

 Lowne's, '90-'92, episternum is the anepimeron. 

 Brauer's, '82, episternum is the katepisternum. 

 Anepisternum (ES"a.) — Anepisternum (of this paper). 

 = Hyperepisternum (Crampton, '08). 

 = Lowne's, '90-'92, "lateral plate." 

 = The episternum of Brauer, '82, a. o. 

 = Hammond's, '81, parapteron. 



= Petri's, '99, antepleura of the mesothorax. On the other hand, his meta- 

 thoracic antepleura is the mesothoracic pleurophragmite. 

 Katepisternum (ES"k) — Katepisternum (of this paper). 

 Katepisternal complex (ES"x) — Katepisternal complex (of tliis paper). 

 Laterale (L") — Laterale (Crampton, '08). 

 = Voss, '04, coxosternum. 



Borner's, '03, coxosternum is the epimeron, episternum and laterale. 

 Verhoeff's, '97, coxasternum is the fusion product of the sternum and coxae. 

 Anterior laterale (La) — Anterior laterale (of this paper). 

 Antecoxal laterale (Lb) — Antecoxal laterale (Crampton, '08). 

 = "Antecoxal piece" (Walton, '00). 



Comstock's, '02. "antecoxal piece" is the antecoxal trochantin. 

 Comstock's, '05, "antecoxal piece" is the furci -sternum. 

 Leconte's, '61-'62, "antecoxal plates" are the lateral cervicals. 

 = Second antecoxal piece (Comstock, '02). 



= Verhoeff's, '03, katopleure in the Blattidae. On the other hand, his kato- 

 pleure in the Dermiptera is the episternal laterale. In the prothorax of 

 Echinosoma, his katopleure is the sternal laterale. Borner's, '03, katopleure 

 in the mesothorax of Anisolabis is the episternal and sternal laterale. In 

 prothorax of Anisolabis it is the sternal laterale and the posterior lateral 

 cervicals. In the Blattida? his katopleure is the antecoxal laterale. 

 Episternal laterale (L" t ) — Episterni-laterale (Crampton, '08). 



= Verhoeff's, '03, katopleure in the Dermiptera. In the Blattidae, however 

 his katopleure is the antecoxal laterale. 

 Sternal laterale (L" 2 ) — Sterni laterale (Crampton, '08). 



= Verhoeff's, '03, "Vorplatte" of the mesothorax in the Blattidae. In the 

 Blattid prothorax his "Vorplatte" is a lateral cervical. 

 Trochantinus (T) — Trochantinus (MacLeay, '30). 

 = Trochantine (Audouin, '24). 

 = Rotule (Strauss-Durkheim, '28). 

 = Prsecoxal plate (Voss, '04). 

 Antecoxal trochantin (TV) — Antecoxal trochantin (Crampton, '08). 

 = Antecoxal piece (Comstock, '02). 



The other usages of the term antecoxal piece are given under the term ante- 

 coxal laterale. 



COXAL TROCHANTIN (7V') COXAL TROCHANTIN (Crampton, '08). 



= Comstock's, '02, entire trochantinus. 

 Trochantinus major (T\) — Trochantinus major (Crampton, '08). 



= Sharp's "epimeron?" in Blabera. 

 Trochantinus minor (7" 2 ) — Trochantinus minor (Crampton, '08). 



= Sharp's entire trochantinus in Blabera. 

 Eucoxa (C'\)— Eucoxa (Verhoeff, '04). 



= Coxa genuina (Walton, '00). 

 Meron (C" 2 )— Meron (Walton, '00). 



Borner's, '03, meron is the epimeron, episternum and laterale. 



= Metacoxa, Verhoeff, '04. 



The term metacoxa means the coxa of the metathorax.
