elongate paraprocts as those of the Phasmids (Figs. 65 and 52, 
“pa”). In other Odonata, the paraprocts “pa” (Figs. 2 and 6) 
are reduced to short appendages, which in some forms, such as 
those shown in Figs. 7 and 8, “pa,” bear projections of various 
shapes; and frequently ventral membranous areas, or calli, and 
pappillz occur on them. . 
The paraprocts of the Dermaptera (Fig. 24) are usually rep- 
resented by the region which bears the label “pa” in this figure; 
but the lobes mesalward to the parameres “pr” in Fig. 24 are 
continuous with the surface of the paraprocts “pa,” and should 
be regarded as parts of the paraprocts. In such Dermaptera as 
Arixenia (Fig. 21) the paraprocts “pa” are more like those of 
the Isoptera, Orthoptera, etc., while the paraprocts of the other 
Dermaptera studied are more like those of certain Plecoptera. 
The paraprocts of the male Embiids are not easily made out, 
due to the reduction of this region, and the strong asymmetry of 
the parts of the male. Despite the fact that the Embiid shown in 
- Figs. 37 and 38 had moderately well-developed wings, I think 
that it is probably a female rather than a male. Its paraprocts 
“pa” (Figs. 37 and 38) are quite like those of the Isoptera (Figs. 
39 and 40, “pa”), which is rather surprising, since the Embiids 
show other undoubted resemblances to the Plecoptera, to which 
they are apparently more closely related than to any other insects. 
The paraprocts of the Mantids (Fig. 71, “pa’’) are rather like 
those of the Blattids (Fig. 77, “ pa”), while those of the Orthop- 
tera (Figs. 61 and 63, “pa’’) resemble the paraprocts “pa” of 
the Isoptera (Figs. 39 and 40) to some extent, although they also 
resemble the paraprocts of the Mantids and Blattids, as may be 
seen by comparing Fig. 63 with Fig. 92. In such Phasmids as 
Timema (Figs. 65 and 42), on the other hand, the paraprocts 
“pa” are rather suggestive of those of the Plecoptera. The para- 
procts “pa” of the Lepismids (Fig. 94) are also somewhat like 
those of certain Plecoptera. 
In the Neuroptera (Fig. 100) there occur on either side of the 
anal papilla “ap,” two plates labeled “pa,’’ which bear processes 
called the “ gonopoda” by systematists. In such Neuroptera as 
Corydalis, the male bears an upper pair of appendages and a 
lower pair, both of which articulate with the region “pa.” These
