McKittrick (1964) placed three blaberid genera, Panchlora Bur- 
meister, Achroblatta Saussure, and Capucina Saussure, in the Panch- 
lorinae. Princis (i960) listed Panchlora , Phortioecoides Rehn, and 
Proscratea Burmeister under the Panchloridae. My studies of male 
genitalia of Blaberidae have shown that Capucina and Phortioecoides 
are members of the Zetoborinae (Roth 1970a). The genitalia of 
Proscratea differ markedly from those of genera I believe should be 
placed in the Panchlorinae and I do not consider it in this paper. 
The male genitalia of species of Panchlora , Achroblatta , Ancho- 
blatta Shelford, Biolleya Saussure, and Pelloblatta Rehn are basically 
similar and I place these five genera in the Panchlorinae. Unfor- 
tunately the male genitalia of an undescribed species of Pelloblatta 
were lost in preparation, due principally to their marked reduction 
and light sclerotization. Princis (1965) placed Pelloblatta in the 
Oxyhaloidae but the male genitalia of members belonging to the 
Oxyhaloinae (Roth, 1971) differ markedly from those of the Panch- 
lorinae. Princis (i960) placed Achroblatta in the Laxtinae, a sub- 
family which he considered provisional (Roth, 1970a), and Biolleya 
in the Latindiidae. McKittrick (1964) placed Laxta in the Epilam- 
prinae, tribe Laxtini. The genus Latindia Stal is an oviparous poly- 
phagid genus whereas Biolleya is an ovoviviparous member of the 
Blaberidae. Princis (i960) placed Anchoblatta in the Brachycolinae 
with a ( ?) but included it under this subfamily in his 1963 Catalogus. 
I consider Princis’ Brachycolinae to be a tribe in the Blaberinae 
(Roth, 1970b). Anchoblatta signifera (Scudder) was originally 
placed in Panchlora , but Kirby assigned it to Achroblatta. Princis 
(1963) listed Anchoblatta signifera with a query under Achroblatta , 
but Gurney (personal communication) regards it to be an Ancho- 
blatta. 
Materials and Methods 
The genitalia were treated with 10% KOH and mounted in Per- 
mount. Considerable care must be taken with these specimens be- 
cause they are so lightly sclerotized and small that they can be readily
