MORGAN HEBARD 369 



Head pinkish cinnamon, dorsal surface darker, sayal brown, with broad 

 post-ocular bar of shining bister on each side. Antennae ferruginous. Pro- 

 notum with disk sayal brown; lateral lobes with the broad postocular band 

 dorsad of blackish bister, which is shining to the principal sulcus, on the meta- 

 zonal portion represented by a narrower suffused line of bister, remaining 

 portions of lateral lobes pinkish cinnamon deepening to cinnamon on meta- 

 zonal portion. Tegmina with dorsal field verona brown; lateral field 

 warm sepia, showing a few minute flecks of verona brown. Abdomen cin- 

 namon buff, with a shining blackish brown patch on each side before the cer- 

 eal bases. Distal portion of cerci and immediate apex of subgenital plate 

 suffused with bister. Cephalic and median limbs pinkish buff, weakly 

 washed laterad with walnut brown. Caudal femora cinnamon buff, dorsal 

 surface with a proximal fleck, two broad transverse bars and entire genicular 

 areas warm sepia, external pagina with a broad longitudinal maculation of 

 warm sepia, which sends a ray to the proximo-dorsal fleck, a very broad band 

 toward the first dorsal band and, before this, after narrowing strongly, it 

 sends a broad band toward the second dorsal band; ventral surface orange- 

 cinnamon, with a row of black dots below the lower marginal carina of the 

 external pagina. Caudal tibiae carnelian red, with a small proximal annulus 

 of warm sepia, spines black, spurs buffy, black tipped. 



Intensification and recession of color pattern causes the series to show 

 decided diversity in superficial appearance. 



In the maximum intensive condition (Florida Mountains), the head and 

 pronotum, including the lateral lobes, are very dark, almost as dark as the 

 very broad postocular bar, while that portion of the ventral surface of the 

 caudal femora against which the tibiae fit is carnelian red. 



In the maximum recessive condition (Sanderson), the general coloration 

 is all much paler, the postocular bar very narrow and terminated at the prin- 

 cipal sulcus, the caudal tibiae and ventral surface of the caudal femora prim- 

 uline yellow, the sternum abdomen and remaining portions of the caudal 

 femora amber yellow, except the dark areas of the external pagina of the 

 caudal femora, which areas in the female are ribbed, this caused by the fact 

 that the sutures of the imbrications are all pale. 



This latter feature does not appear to occur in the male sex of the species, 

 though it is shown to various weak degrees in all the paler females of the series. 

 It is the normal condition in both sexes of ponderosus. 



Specimens Examine!: 69; 37 males, 27 females and 5 immature individuals.
