dorsal (del) and ventral (vcl) forced open. 



94. Same, dorsal view of left paramere or paramere lobe, pm, shaft of paramere; 



IP, 11-, etc., secondary processes from paramere lobe. 



95. Same, lateral view of left paramere. Lettering as in Fig. 94. 



96. Periplaneta hrnnnea Burm. Ventral view of right paramere. For lettering 



see Figs. 91 and 92. 



97. Same, dorsal view of 1-eft paramere. Lettering as in Fig. 94. 



98. Periplaneta americana L. Ventral view of right paramere. For lettering 



see Figs. 91 and 92.

Plate XI. 

 (Blattoidea, Mantoidea). 



100. Periplaneta fuliginosa Brunn. (Blattoidea). Dorso-posterior view of 



genitalia, the 9th sternum strongly depressed, pm, main shaft of left 

 paramere; the secondary processes borne by 11 lying to the right; pm^, 

 basal part of shaft of right paramere; pm-, the principal terminal process. 



101. Blaberus atropos Serv. (Blattoidea). Posterior view of end of abdomen, 



the 9th sternum, which is asymmetrical, somewhat depressed to show 

 the genitalia. The 10th tergum is foreshortened. The right paramere, 

 a long copulatory hook, is completely retracted within its sheath. The 

 right paramere lobe extends far to the left in the form of a horizontal 

 flap. 



102. Same, left paramere. 



102. Same, dorsal view of left paramere. df, dorsal flap. 



103. Same, postero-dorsal view of left paraniere, with the dorsal flap (df) 



reflected. 



104. Stagmomafttis Carolina {L.) (Mantoidea). Posterior view of end of abdomen, 



the 9th sternum strongly depressed. 1pm, the main process of the left 

 paramere lobe, probably homologous with pm in Fig. 100; 11^ 11^, pro- 

 cesses from left paramere lobe; df, dorsal flap of right paramere (cf. 

 Figs. 100 and 101). 



105. Same, dorsal view of genitalia in natural position. The clasper (cl) is 



represented as showing through, as in a cleared preparation, r pmb, base 

 of right paramere. Other lettering as in Fig. 104. 



106. Same, ventral view of genitalia, r pm, 1 pm, right and left paramere bases. 



Other lettering as in Fig. 104. 



107. Same, ventral view of isolated right paramere. 



108. Same, lateral view of left paramere. Lettering as in Fig. 104. 



109. Newly hatched nymph of undetermined Japanese Mantid. Ventral view 



of terminal segments, showing well-marked supra-anal plate and processes 

 of the 9th sternum, representing coxites and styli.
