In this tribe the apex of L2vm is solidly joined to a relatively 
broad L2d. In Moncistria (Figs. 127-138), the prepuce (Figs. 127 , 
I 30 J I33> 136, 138) is almost entirely covered by rows of small, 
closely packed spines and extends well below the posterior margin 
of L2d. In Monachoda (Figs. 139-150), Hiereoblcitta (Figs. 15 1- 
153), and Petasodes (Figs. 154-162) the prepuce extends little or 
not at all beyond the margin of L2d and many of the preputial spines 
(considerably fewer in number than in Monastria ) are usually 
hidden under L2d. In Petasodes reflex a (Fig. 160) there is a 
marked reduction in number of preputial spines and these are very 
lightly sclerotized. 
McKittrick (1964) placed Petasodes in the Brachycolini, but all 
the members of this tribe have L2d clearly separated from L2vm by 
a membrane (see below). Rehn’s (1937, p. 241) statement that 
Hiereoblatta is related to Monastria is justified by the similarities 
in male genitalia. However, the shape of L2d and the preputial 
spines hidden under it in Hiereoblatta (Figs. 148, 1 5 1 ) indicate a 
closer relationship to Monachoda (Figs. 142, 144, 145) than to 
Monastria (Figs. 127, 130, 133, 136, 138). 
Brachycolini: Bionoblatta Brachycola , Hormetica, OxycercuSj 
Parahormetica , Phoetalia , Sibylloblatta (Figs. 163-211). 
This tribe is clearly differentiated from the Blaberini and Mona- 
striini in that L2d is not solidly attached to L2vm, but is separated 
from it clearly by a membrane. The spines on the prepuce vary in 
size from relatively large in Phoetalia (Figs. 175, 178) to small 
in Parahormetica (Figs. 199, 202, 203), Oxycercus (Fig. 206), 
Bionoblatta (Fig. 209), Sibylloblatta (Figs. 195, 198), and Brachy- 
cola (Fig. 193). 
Princis (i960) placed Phoetalia in the Epilamprinae and McKit- 
trick (1964) assigned it (as Leurolestes) to the Diplopterinae. The 
male genitalia of Phoetalia are not characteristic of either of these
