minute undulating irregularities reminiscent of some specimens of 
P. indicus (cf. Fig. 61 with Figs. 14-15, 18). The L2d is apparently 
represented by a small sclerotized region of the prepuce widely sep- 
arated from the apex of L2vm (Fig. 60). The vertical downward 
curvature of the cleft and indentation on the outer margin of the 
lower lobe of Li (Fig. 62) is unique for this phallomere in the 
Blaberidae; the lower lobe of Li lacks setae. 
The supra-anal and subgenital plates of D. punctata are shown in 
figures 58-59. The genital phallomeres of 3 other undetermined 
specimens of Diploptera (Figs. 65-67, 70-72, 75-77) are indistinguish- 
able from D. punctata. The subgenital plates of these specimens 
(Figs. 64, 69, 74) are similar to D. punctata (Fig. 59), but the 
shapes of the supra-anal plate of 2 of the specimens differ somewhat. 
In the specimen shown in figure 63, there is a deep invagination on 
the posterior margin ; however because of the slight asymmetry of the 
indentation this may be an aberrant punctata. This specimen is from 
Hawaii and although D. punctata is widespread in the Pacific it is 
the only species of the genus recorded from Hawaii (Princis, 1965). 
Except for size, the phallomeres (fig. 78) of D. mimr are almost 
indistinguishable from D. punctata; the sclerotization (L2d) of the 
prepuce found in D. punctata is absent in minor. The supra-anal 
plate of D. minor is slightly more rounded (fig. 79) than that of 
punctata (fig. 58).
