LXIV. — On the Internal Appendices of the Oenital Apparatus 

 of the Orthoptera. By M. A. FeNARD*. 



There is an entomological question which for some long time 

 has appeared to require to be taken up, and to which it will 

 be useful to call attention, namely the internal appendices of 

 the genital apparatus in male and female insects. I have 

 during the past three years and more studied this matter, and 

 have commenced with the order Orthoptera. I have the 

 honour to communicate to the Academy some of the results 

 obtained, confining myself for the present to the male organs.
