The male genitalia of cockroaches have proved to be extremely use- 
ful in showing generic relationships (Roth, 1970a, 1970b). This 
study of 8 genera again shows the importance of using internal male 
genital structures in grouping genera of Blattaria.. 
The genitalia of species of the following genera are illustrated in 
this paper: Galiblatta Hebard, Dryadoblatta Rehn, Poroblatta Heb- 
ard, Nauclidas Rehn, Notolampra Saussure, Colapteroblatta Hebard, 
Litopeltis Hebard, and Cariacasia Rehn. Princis (i960) placed 
Dryadoblatta and Notolampra in the Epilampridae (Epilamprinae 
and Phoraspinae respectively) and the other 6 genera in the Blabe- 
ridae, subfamily Laxtinae. McKittrick (1964) placed Laxta in the 
Epilamprinae and Princis {in Roth, 1970a) considered his subfamily 
Laxtinae provisional and predicted it probably would be split up. 
McKittrick (1964) placed Litopeltis , Poroblatta (with a query), 
and Galiblatta {in Roth, 1968) in the Epilamprinae. I follow Mc- 
Kittrick in placing all ovoviviparous cockroaches in Blaberidae and 
consider all the above genera as belonging to the Epilamprinae. Other 
genera of Epilamprinae will be treated in future publications. 
Materials and Methods 
The source of each of the museum specimens illustrated is given 
using the following abbreviations: (ANSP) = Academy of Natural 
Sciences, Philadelphia; (BMNH) = British Museum (Natural 
History), London; (L) = Zoological Institute, Lund, Sweden; 
(MCZ) = Museum of Comparative Zoology, Harvard University, 
Cambridge, Mass.; (USNM) m United States National Museum, 
Washington, D.C. Geographical collection data and the names of 
specialists who identified the specimens, if known, follow these 
abbreviations. The number preceding the abbreviations refers to 
the number assigned the specimen and its corresponding genitalia 
(on a slide) which are deposited in their respective museums. 
Results and Discussion 
McKittrick (1964, p. 37) stated that “the slight differences evi- 
dent in the character systems barely justify the designation of
