tawny, heavily suffused with dark cinnamon brown. Xumor- 

 ous differences in shade and contour-^^ of the markings is shown 

 by the series before us, linking up in every way the extremes. The 

 southwestern material averages near the maximum intcnsi\e, but 

 in all series individual differences are found. 



9. (Maximum recessive.) (Staten Island, New York.) Head 

 with vertex ochraceous-buff, below with a vertical blackish chest- 

 nut lirown band, which is narrowest below the antennal sockets, 

 ocellar spots and genae warm buff". Underparts and limbs anti- 

 mony yellow, the former mottled with blackish brown; ventral 

 surface of abdomen mesad cinnamon brown, with broad lateral 

 margins of suffused antimony yellow and subgenital plate suff'used 

 ochraceous-tawny. Pronotum with disk heavily clouded with 

 russet, which shades into the narrow cephalic and broader lateral 

 margins of ochraceous-tawny.-^-' Every gradation is found from 

 this to the following condition. (Normal eastern, occasional west- 

 ern.) Browns darker and more solid. Disk of pronotum mars 

 brown, this marking continued to and including all of the caudal 

 margin of the pronotum, but with a medio-longitudinal streak of 

 tawny ; this marking not sharply defined from the moderately broad 

 cephalic and broader lateral margins of the pronotum, which are 

 antimony yellow. Tegmina translucent mars brown, with mar- 

 ginal and proximal portions of scapular fields much paler, warm 

 buff, the latter suffused. Dorsal surface of abdomen blackish 

 brown, the segments margined with ochraceous-tawny laterad to 

 individually variable degrees. Many intermediates in the series 

 connect this with the following striking type. (Maximum inten- 

 sive.) (Rare eastern, frequent northwestern, normal southwest- 

 ern.) Head blackish chestnut brown, except ocellar spots and lateral 

 porti(Mis of genae, which are antimony yellow. Underparts and 

 limbs cinnamon brown, ventral surface of abdomen blackish chest- 



-^' Two distinct types of pronotal marking occur, these particularly strilcing in the 

 maximum intensive coloration. In one, the lateral margins of the dark area are nearly 

 straight; in the other, these margins bordering the disk of the pronotum are there decid- 

 edly convex. 



-■*- Such females are the most difficult to separate from those of divisa. But one other 

 specimen before us, from Lakehurst, New Jerse>-, shows this degree of recession, the 

 genae, however, being much suffused with dark brown.
