sas (Douglas County), south to at least north-central Florida (Ormond) 

 and extreme southern Texas (Brownsville), westward to New Mexico. 

 Its known vertical range is thus seen to be from sea-level to at least 

 two thousand and five hundred feet (Sulphur Springs), and probably 

 considerably higher on the strength of the New Mexican record, but lack 

 of exact locality in the latter case deprives it of much of its impor- 

 tance. The specimens were all taken in the months of May and June. 



Remarks. — There seems to be little doubt in our minds as to the 

 propriety of synonymizing Kakerlac schaefferi with this species, as 

 while no breeding experiments have been made to verify the opinion, 

 schaefferi possesses the characters and coloration one would expect 

 in the female of bolliana after having studied the sexes of forms like 

 johnsoni, deropeltiformis and americana, the latter being an absolute 

 parallel in the degree of differentiation of the sexes. 



The pale form seems to be most prevalent in material from north- 

 eastern Texas, the only specimens seen by us in this phase being from 

 Paris, Texas, and one from Texas (Belfrage) without further data. 



Specimens examined. — Thirty-eight; thirty-three males, five 

 females : 



Sulphur Springs, N. C. Five males. (Hebard Collection.) 



Tryon, N. C. Eight males. (U. S. N. M.) 



Raleigh, N. C. Five males, two females. (A. N. S. P., Hebard 

 Collection and U. S. N. M.) 



North Carolina. Two males. (U. S. N. M.) 



Swansea, S. C. One male. (U. S. N. M.) 



Atlanta, Ga. One female. (A. N. S. P.) 



Brunswick, Ga. One male. (A. N. S. P.) 



Paris, Tex. Five males. (U. S. N. M.) 



Round Mountain, Tex. Two males. (A. N. S. P.) 



Hockley, Tex. One male. (U. S. N. M.) 



Esperanza Ranch, Brownsville, Tex. Two males, one female. 

 (U. S. N. M. and Brooklyn Inst. Arts and Sci.) 



Port Isabel, Tex. One female. (U. S. N. M.) 



Texas. One male. (U. S. N. M.) 



Ischnoptera desertse (Rehn and Hebard).

As this species has recently been well described and figured it seems 

 unnecessary to redescribe it in this paper. The type is still unique, 

 and the probability of its being the female of a species of Ischnoptera 

 is so great that we have placed it, tentatively at least, as a valid species 

 of the genus under consideration.
