Dr. Malcolm Burr’s Revision of the Genus Diplatys. 47 
Note.—The above paper was completed before I received Dr. 
Friedrich Zacher’s Beitrag zur Kenntnis der Pygidicraniden und 
Diplatyiden (Ent. Rundschau, 1910, p. 105), in which the author 
divides Diplatys into the following Subgenera : Diplatys, sensw stricto, 
Verhoeffiella, (type, D. aethiops, Burr), Paradiplatys (type, D. 
conradti, Burr), and Nannopygia, Dohrn, restored, with a new species. 
N. picta, from East Africa. 
These are based exclusively upon the structure of the male 
genitalia, but Zacher’s system does not conflict with mine. 
The question of the use of the genitalia for systematic characters 
in the Dermaptera is too new and too profound to be discussed 
without great care and consideration. 
Dr. Zacher’s brief paper above mentioned is a preliminary bulletin 
of his large and very important work just published under the title 
“Studien ueber das System der Protodermapteren,” in the Zool 
Jahrb., 1911, pp. 303-400.
