Although the males of most species currently assigned to Epilampra 
lack tergal glands, there are several with dorsal abdominal modifica- 
tions (Roth, 1969a) which are presumably involved in sexual be- 
havior. The presence or absence of tergal glands and the differences 
in the genitalia of these two groups of Epilampra warrant their being 
placed in different genera. 
Materials and Methods 
The material used in this study were all museum specimens which 
were softened and had their genitalia removed after slitting the lateral 
margins of the terminal abdominal segments. The genitalia were 
treated with 10% KOH, cleared and mounted in Permount. In 
the illustrations, the hooked right phallomeres are mounted ventral 
side up, and phallomeres Li and L2d are mounted dorsal side upper- 
most. 
The source of each of the specimens illustrated is given, using the 
following abbreviations: (AMNH) = American Museum of Natu- 
ral History, New York; (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) = United States National Museum, Washington, 
D.C.
