IIo NORTH AMERICAN BLATTIDAE 



pronotum and limbs are tawny or approaching cinnamon brown, 

 with abdomen more hea\ily suffused and cerci solidly blackish 

 brown. Occasionally paler males, particularly those from Florida, 

 have the cerci very dark. Occasional examples, particularly 

 among the more northern specimens, have the vertex and median 

 portion of the face somewhat darkened; a medio-vertical band, 

 however, is never found as conspicuous there as is normal in 

 iihleriana. 



9 . (Maximum recessive.) Head ochraceous-tawny, becom- 

 ing clear and paler laterad, limbs clear, pale, ochraceous-tawmy, 

 ventral surface of abdomen tawny. Pronotum tawny, fading to 

 ■ochraceous-tawny laterad. Tegmina transparent tawny, tinged 

 with cinnamon-rufous, with marginal field paler. Dorsal surface 

 of abdomen cinnamon-rufous, the proximal segments broadly 

 sufTused meso-distad with reddish brown, this increasing caudad, 

 the distal segments and cerci dark reddish brown. Every grada- 

 tion to the maximum intensive condition is found, the majority of 

 specimens, however, being nearly intermediate, with the tawny 

 coloration sligh-tly deeper, becoming more sharply ochraceous 

 laterad; tegmina taw^ny, with marginal field ochraceous-tawny, 

 and abdomen blackish brown, slightly paler meso-ventrad. (Max- 

 imum intensive.) Head ochraceous-tawny, much suffused betw'een 

 ocellar spots and clypeal suture w^ith deep chestnut brown. Pro- 

 notum blackish brown, becoming rather sharply ochraceous-buff 

 laterad. Tegmina translucent blackish brown, with costal area 

 paler and marginal field ochraceous-buff. Limbs tawny. Abdo- 

 men above and below, and cerci, blackish brown. This extreme 

 is very rare, but numerous specimens show different degrees of 

 near approach. It is of interest to note that the pronotum in this 

 sex of the present species apparently is never solidly dark, a fre- 

 quent condition in females of iihleriana. The series from the 

 southeastern United States, the majority taken in the pine woods, 

 show a distinctly more reddish brown general coloration than do 

 the other series. ^^^ 



The ootheca of this species is very similar to that of virginica, 

 but larger, averaging 3.7 mm. in depth, with vertical divisions 

 slightly less widely spaced.
