Eurycotis floridana (Walker) 



I.S6S. Periplancta floridana Walker, Cat. Blatt. Br. Mus., p. 135, [ 9 : St. John's 

 Bluff, east Florida: North America.] 



This species, which is native and apparently confined in dis- 

 tribution to the Sabalian and Tropical Floridian Zones of the 

 southeastern United States, is fully discussed on page i66. The 

 present adventive example was probably shipped north in packing 

 boxes or other freight.

Eurycotis opaca (Brunner) 



1865. P[olyzosteria] opaca Brunner, Xouv. Syst. Blatt., p. 216. [cf, Cuba.]. 



This Cuban species is closely related to E. floridana. It is dis- 

 tinguished by its larger size, generally rougher surface, decidedly 

 broader head and normal darker coloration.

Pelmatosilpha rotundata Scudder 



1900. Pehnatosilpha rotundata Scudder, Proc. Davenport Acad. Xat. Sci., viii, 

 p. 93, pi. 2, fig. 5. [cT. Texas; 9. Panama.] 



We have examined the figured male type from Texas, which we 

 here designate as lectotype. There is no doubt that this specimen 

 was accidentally introduced, almost certainly from Central Ameri- 

 ca. In the unstudied series before us, the species is represented in 

 material from that region, but is not found in any of the Mexican 

 series. 



The insect is a dark, glossy, medium-sized roach, with broadly 

 rounded tegmina extending to the apex of the abdomen and show- 

 ing no \'eins on their polished dorsal surfaces. 



Periplaneta americana (Linnaeus) 



1758. \Blatta] americana Linnaeus, Syst. Nat., Ed. X, p. 424. [America.] 



This species is fully discussed on page 178.
