large. Supra-anal plate rounded with a mesal indentation. Cerci 
short, reaching to about the hind margin of supra-anal plate. Sub- 
genital plate ( cf ) asymmetrical, broadly, but weakly concave on 
right side; styli about equal. Male genitalia: L2d a small irregu- 
larly shaped sclerotized plate separated from L2vm ; prepuce densely 
spicular in part, with or without large spines on the free margin 
(Figs. 15, 17, 20, 23, 29, 30; see Fig. 29 for naming of parts), a 
light sclerotized plate present ventral to the L2vm. The membrane 
lying above the L2vm may have a number of small spines (Fig. 15) 
but in the flattened KOH preparations are not shown in their normal 
position (Figs. 20, 23). R2 unique in having a finger-like basal 
projection directed toward the inner curved margin of the hook 
(Figs. 16, 18, 21 , 31). Right paraproct considerably more developed 
than the left (Figs. 13, 27-28). 
The presence of large spines on the prepuce is, as far as I know, 
unique for a member of the Epilamprinae, and has only been found 
in the Blaberinae. However, in that subfamily the spines usually 
closely surround the L2d (Roth, 1970a). Because of the unusual 
genital structures, I place Pinaconota in the tribe Pinaconotini. 
The following is a redescription of Pinaconota bifasciata supple- 
menting that of Saussure: 
Pinaconota bifasciata (Saussure) 
(Figs. 1-23) 
Blatta bifasciata Saussure (Rev. Mag. Zool., 1862, p. 165; Mem. Hist. nat. 
Mexique, Geneve, 1864, 4, p. 98, $ 9). 
Phyllodromia bifasciata (Saussure) (Brunner, Nouv. Syst. Blatt. Vienne, 
1865, p. 94). 
Epilampra bifasciata (Saussure) (Miss, scient. Mexique, Rech. zool. Paris, 
1870, pt. 6, p. 84, pi. 2. Figs. 44, 44A). 
Pinaconota bifasciata (Saussure) (Rev. suisse Zool. 1895, 3, p. 337). 
cf. (Figs, i, 5, 7). Face smooth with scattered small setae, 
vertex exposed. Pronotum semi-circular, somewhat flattened but with 
sides slightly deflexed, hind margin subtruncate or weakly curved. 
Tegmina abbreviated, reaching to about the middle of fourth ter- 
gite (Fig. 7) or fully developed extending beyond the end of the 
abdomen (Figs. 1, 5), rounded apically; plical furrow strongly 
arched, the furrows from both tegmina meeting to form a semi-ovoid 
anal field, anal veins of left tegmen shallowly punctate; veins of 
right tegmen punctate only in that portion not covered by the over- 
lapping left tegmen; many veins on other parts of the tegmina also 
shallowly punctate. Abdomen broad. Supra-anal plate rounded, 
mesally indented. Cerci not extending beyond hind margin of supra-
