different subfamilies (e.g., Capucina [Zetoborinae,] Nauphoeta and 
Gromphadorhina [Oxyhaloinae] ) have spermatophores ( Graves, 
1969) somewhat similar in shape to those of Diploptera and Pros - 
crated. 
The L2d of Proscratea is well developed, somewhat crescent- 
shaped (but variable) and widely separated from L2vm (Figs. 46, 
49, 52-54). The membrane above L2d is modified to form a sac-like 
projection whose surface is covered with microspicules; this structure 
is not found in the other Pycnoscelinae. The R2 is short, stout, and 
lacks a subapical incision (Figs. 47, 50, 5 5 _ 5 7 ) * The shape of the 
cleft in the Li of Proscratea does not curve upwards (Figs. 48, 51) 
as it does in Pycnoscelus (Fig. 9) or Stilpnoblatta (Fig. 39). The 
genitalia of Proscratea oomplanata (Figs. 46-48) are indistinguishable 
from the specimen provisionally determined by Rehn (1932, pp. 71- 
72 ) to be Proscratea peruana ( Figs. 49-5 1 ) . 
Because of the differences between the Li and the presence of the 
modified membrane over the L2d of Proscratea , I suggest 2 tribes in 
this subfamily: 
1. Pycnoscelini : Pycnoscelus , Stilpnoblatta 
2. Proscrateini : Proscratea 
Diplopterinae 
Princis (1965) placed the genera Diploptera and Diplopterina in 
the Diplopteridae. The genitalia of Diplopterina are closer to cer- 
tain members of the Perisphaeriinae (unpublished observations) and 
I consider it to be a member of this subfamily. McKittrick (1964) 
included 2 genera, Diploptera and Phoetalia {— Leurolestes) in 
Diplopterinae. As indicated above, the genitalia of Phoetalia place 
it in the Blaberinae (Roth, 1970b). Diploptera punctata (Esch- 
sdholtz) is the only viviparous cockroach known and, at present, I 
consider this genus to be the only member of the Diplopterinae. 
Other members of the Blaberidae, whose reproduction has been in- 
vestigated, are ovoviviparous. Princis (1965) lists 7 species of 
Diploptera and it would be of interest to determine if those, other 
than punctata, are viviparous also. 
The arrangement of the phallomeres of Diploptera minor Brunner 
is shown in figure 78. The male genital phallomeres of D. punctata 
(type of genus) are shown in figures 60-62. The curved hook (R2) 
lacks a subapical incision, is more slender and elongate, and more 
strongly curved (Fig. 61) than in most of the species of Pycnos- 
celinae. The inner margin of the curved portion of the hook has
