continuous piece, the divisions between being filled by a sort of 

 amalgam of thin transparent chitin. 



The whole of these pieces, as well as the basal plate and para- 

 meres, which in their ensemble Berlese conveniently collects 

 under the name Perlfallo (26), are, it must be remembered, 

 simply chitinous plaques developed iipon the outside tube of the 

 apparatus. In PectinopygLOS these are remarkable from their 

 miscellaneous character, whereas in other Mallophaga the meso- 

 somal parts are usually capable of ready classification into the 

 endomeres and telomeres and penis.
