108 R- Shelford, 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 (S) 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 (3) 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 smaragdma Br. (syn. vitellina Gerst.) and P. adusta 

 Gerst. from West Africa, now fall into the genus Nauphoeta. 



Subfam. Blaberinae. 



Hemiblabera manca Sauss.
