The battleaxe-shaped L2d is continuous with a sclerotized portion 
of the prepuce and is not separated from the prepuce by a thin clear 
membrane (as is usual in the Abdomennigrum and Burmeisteri 
Groups). In the Mexicana Group, L2d is not a distinct sclerite 
lying above the prepuce but is a flat sclerotization lying on the same 
plane as the prepuce. 
There has been some question about the placement of Epilampra 
heusseriana Saussure. According to Hebard (1921) this species 
“. . . has been assigned to the genera Calolampra and Audreia , due 
mainly to the fact that the type female had short truncate tegmina. 
Though this is true for the female sex, the male before us is seen to 
have fully developed organs of flight, and shows no characters which 
would warrant its being placed other than in the genus Epilampra .” 
Princis (1967) lists heusseriana under Audreia apparently following 
Albuquerque (1964). The male genitalia of heusseriana are typical 
of many other Epilampra and tend to support Hebard’s placement 
of the species. 
Sodalis Group 
\Epilampra sodalis Walker (Figs. 308-328)] 
In this group which includes E. sodalis and possibly several unde- 
termined species, there is no distinctive prepuce and L2d is a single 
more or less clawlike sclerotization. In a recent paper I indicated 
that the male of E. sodalis had tergal modifications on segments 3 
and 4 (Roth, 1969a, p. 202, Table 10, footnote b). I have examined 
males of E. cinnamomea Hebard, which Princis synonymized with 
sodalis Walker (Princis, 1958, p. 16), and found that the males lack 
tergal glands. I also examined Walker’s Type 9 of sodalis and con- 
cur with Princis that cinnamomea is a synonym of this species. The 
male genitalia of sodalis (Figs. 308-328) are distinctive; L2d re- 
sembles a single tarsal claw, and R2 is rather stout with a subapical 
“incision” represented by a fine line which is best seen in a lightly 
sclerotized specimen (Fig. 327', arrow). 
The genitalia (Figs. 329-331) of the specimen previously reported 
by me as sodalis (Roth, 1969a) (here designated as Epilampra sp. 
A) are only subtely different from those of sodalis ; L2d (Fig. 329) 
and R2 (Fig. 330) are slightly more slender in sp. A. However, 
there is a striking difference in the pronotal markings of these two 
species. In sodalis the microspots are all small and more or less the 
same size whereas in sp. A there are distinctly large spots, inter- 
spersed among small ones. These two forms are probably sibling 
species. Species A is the only Epilampra I know in which male tergal
