with brown. The post-ocular fuscous stripe is as heavy on the 

 prozona as in the most decidedly marked males of the series of 

 M. australis before us. 



A single specimen was found on the somewhat marshy, sandy 

 ground covered with low vegetation (Sullivan Island), but the species 

 was found fairly numerous in moist places in the pine woods in the 

 low heavy undergrowth of plants and scrub oaks less than a foot 

 in height (Magnolia). A thunder storm prevented the accumulation 

 of a large series at the latter locality. In mid-August the young 

 alone were to be found in a depression overgrown with tall grasses 

 in long-leaf pine woods (Ashley Junction), and in late July a few 

 small young were found in short grasses in a somewhat swampy 

 spot in similar woods of the flat country just below the fall line 

 (Augusta). 



The species was previously known from the three male type speci- 

 mens from Smithville, at the mouth of the Cape Fear River, in 

 extreme southeastern North Carolina, and from one male and three 

 young from Denmark, South Carolina.

The most important characters which separate this species from 

 the others of the present group are given in the preceding analysis. 

 The figures of the genitalia, which accompany the original description, 

 are faulty and misleading. The type, which is 22 mm. in length, 

 is as large as the largest male of M. australis, which species averages 

 considerably less than this measurement. The type of the present 

 species remains the unique adult. 



The above series of about half-grown young was taken in the 

 heavy undergrowth of the long-leaf pine forest along the Flint River.

More closely related to M. australis, attenuatus and hebardi than 

 to M. decorus, differing decidedly in the characters given in the 

 analysis on pages 212 to 215. Females are scarcely separable from 

 dark females of M . decorus, though the males show wide differences 

 in the two species.
