8o NORTH AMERICAN BLATTIDAE 



discal sulci. Tegmlna of the same color proximad, translucent; 

 fading toward buckthorn brown distad. This condition is normal 

 in eastern material, showing individual different degrees of inten- 

 sity in each series. The material from Kansas, Oklahoma and 

 Brownsville, Texas, is about intermediate, while the remaining 

 Texan series show individuals which are moderately paler or of 

 the extreme recessi^•e coloration. (Recessive.) General color of 

 entire insect ochraceous-buff, becoming paler on lateral margins 

 of pronotum and marginal field of tegmina and ochraceous-tawny 

 toward the subgenital plate. Head shining blackish chestnut 

 brown, ocelli light buff, clypeus of the general coloration. No 

 exceptions to the very dark cephalic coloration appear to occur. 

 9 . Shining blackish chestnut brown, femora slightly paler, re- 

 maining portions of limbs and the cerci dark chestnut. Minute 

 ocellar spots buffy. 



The ootheca is carried with suture laterad. Its surface is smooth, 

 with rather widely spaced transverse divisions. The suture bears 

 minute, rather widely separated knobs; these are, however, less 

 widely spaced than the transverse divisions. 



This species is not as frequently encountered as many of the 

 genus. Its range is known to extend from Raleigh, North Caro- 

 lina and Brunswick, Georgia, ^^^ westward to the Mexican border. 

 Though described, in part, from New Mexico, our most western 

 records are Ellis, Kansas and Rio Frio, Texas. Northward in the 

 Mississippi Valley region, it is known as far as Nebraska City, 

 Nebraska and Iowa City, Iowa.
