cies and their genitalia are so different that by my criteria I place 
them in different groups. The shape of the L2d of E. columbiana 
(Figs. 208, 21 1, 214, 217, 219) is distinctly fishlike and it is easily 
distinguished from mexicana (Figs. 2, 5, 8, 10, 11, 12). 
The L2d and prepuce of E. latifrons (Fig. 299) are very similar 
to those of abdomennigrum (Figs. 50, 53-55); the Li of latifrons 
lacks a setal brush (Fig. 301), whereas these setae are present in 
abdomennigrum (Fig. 52). 
The unique tarsal-clawlike shape of the L2d of basistriga (Figs. 
220, 223, 226-228) distinguishes this species from any other Epi- 
larnpra. Hebard (1929, p. 369) believed that E. delicata (Fig. 227) 
(= basistriga) seemed to be near E. berlandi , and E. jorgenseni and 
apparently even more closely related to A udreia catharina ; this con- 
clusion is not supported by genitalia. E. berlandi (Figs. 114-117) 
and jorgenseni (Figs. 97-113) are in the Abdomennigrum Group; 
and Shelford’s Audreia catharina with genitalia (Figs. 37-39 in Roth 
1970) completely different from those of Epilampra is now in the 
genus Poeciloderrhis. 
Two species, E. thunbergi (Figs. 238-243) and E. castanea (Figs. 
244-246) are apparently closely related; the R2’s (Figs. 239, 242, 
245) and Li’s (Figs. 240, 243, 246) are especially similar. Hebard 
apparently had misidentified one of these specimens (Figs. 241-243) 
of thunbergi as E. testacea. Princis (1949, p. 65) discussed thunbergi 
(Type: cf ?, without abdomen) and compared it with grisea and 
also stated that E. substrigata Walker may prove to be a synonym of 
thunbergi. The genitalia of grisea (Figs. 68-96) and substrigata 
(Figs. 196-207) are distinctly different from Princis’ thunbergi (Figs. 
238-240). Hebard (1929, p. 365) stated that what he considered to 
be testacea [= thunbergi ] (Figs. 241-243) was closely related to 
guianae (Figs. 118-126) ; but this conclusion is not supported by the 
genitalia which are markedly different. 
The specimen of E. castanea was recorded by Hanitsch (1931, 
p. 385) as Epilampra puncticollis. E. puncticollis is now in Rhab- 
doblatta, a genus not found in the New World (Princis, 1967). 
This specimen is from the Fry Collection in BMNH and Hanitsch 
in reporting it commented that “No particulars are available concern- 
ing the specimens from the late Mr. Alexander Fry’s collection. Some 
of the material seems Malayan, but the rest is almost certainly 
Neotropical.” Fry lived at one time in Rio de Janeiro and this 
specimen most probably came from there. 
Subgroup C / azteca , crossea) : The prepuce is usually poorly de- 
veloped or indefinitely outlined ; if the prepuce is clearly outlined, its 
surface sculpturing is scalelike.
