This circumtropical species, which thrives in the vicinity 
of human habitations, appears to be parthenogenetic in the 
Americas. The smallest immatures here recorded have the 
subgenital plate bearing styles; the brief cleft meso-distad, 
however, determines the sex with certainty.

This is a circumtropical domiciliary species. Immatures are 
very differently colored than the adults, particularly the head 
which is dark and unicolorous, with pale mouthparts. Adults 
from the Galapagos have been recorded by Bruner as the 
synonymous bivittata and by Scudder correctly. Immatures 
were, however, recorded from these islands as Nauphoeta levi- 
gata by Bruner and as Nauphoeta circumvagans by Scudder, as 
material before us from the United States National Museum 
shows. 
MANTIDA 
A single species of Mantid is known from the Galapagos and 
is peculiar to these islands.
