108 R. Sueurorn, Blattidae. 
Panchlora. 
Vertex of head almost covered by pronotum; pronotum posteriorly 
obtusely produced. Femora without any apical spines. Posterior 
metatarsus equal to or exceeding the length of the succeeding joints, 
its pulvillus apical. Sub-genital lamina (Z) asymmetrical. Colour 
some shade of green. 
Nauphoeta. 
Vertex of head more exposed. Pronotum usually less obtusely 
produced posteriorly. Either the mid- or hind-femora (sometimes 
both) with at least one apical spine. Posterior metatarsus shorter 
than succeeding joints, its pulvillus occupying the greater part of 
the joint. Sub-genital lamina (4) symmetrical, posterior angles 
spinously produced outwards and backwards. Colour variable, 
frequently flavo-testaceous. 
Adopting these criteria, which I believe to be reliable, we find 
that Nauphoeta is dominant in Africa, includes one cosmopolitan 
species, and has one representative, that just described, in the New 
World. Panchlora is dominant in the New World, includes one or 
two species that sporadically appear in Europe, and has three African 
representatives. 
“ Panchlora smaragdina Br. (syn. vitellina GerstT.) and P. adusta 
GeRST. from West Africa, now fall into the genus Nauphoeta. 
Subfam. Blaberinae.
