only remaining maculations suggesting those of Pardalophora apiculata 

 (H. tuberculatus of authors), but much less distinct. This specimen, 

 which shows the greatest amount of recession in color pattern of any 

 individual of the present species we have seen, has in consequence, 

 as is often true in such cases, a decidedly different facies, since the 

 normal tegminal markings are all but obliterated. 



In the present species minor differences exist in every large series 

 in robustness, rugosity of the pronotum and angulation of the caudal 

 margin of the same, length of tegmina, number and size of tegminal 

 maculations and wing length. None of these differences are, however, 

 of any geographic importance. The extremes in tegminal length 

 of the material at present under consideration are as follows : males, 

 23.2 to 28 mm., females 28.8 to 35 mm. A number of th*e specimens 

 before us of the present species from Nebraska exceed the maximum 

 of these measurements, as is also true of western specimens of Par- 

 dalophora phoeni copter a. 



The specimens before us exhibit much variation in the number and 

 situation of the tegminal maculations, varying from a type in which 

 the tegmina are covered with small and more or less disconnected 

 maculations, to one in which these markings are much fused, forming 

 five or six broad irregular transverse bands. 



All of the adult specimens from above the fall line and north of 

 Winter Park, North Carolina, have the disk of the wings primrose 

 yellow, varying much less frequently to wax yellow. Southward 

 nearly one-half the specimens from localities below the fall line have 

 this portion of the wings peach red to orange pink, 54 while the re- 

 mainder vary from light orange yellow to citron yellow. As in the 

 last species treated, the width of the wing band varies considerably. 



This species begins to appear adult about the middle of July, and 

 by late August and early September is found mature in the largest 

 numbers over that portion of its range treated in the present paper. 

 The species is widely distributed and common through upland 

 fields (Virginia localities), in fields near woods and through the under- 

 growth, particularly of pine woods (other records), while at Stone 

 Mountain, Georgia, it was found in bunch-grass growing on other- 

 wise bare granite slopes. In southern Georgia and northern Florida 

 it is usually rather uncommon, only seldom being found abundant 

 locally (Spring Creek, Georgia; Jacksonville, Florida). The records 

 given above are the most southern for the species in Florida. 



M These specimens are distributed through the present series as follows: Winter 

 Park, 4 cf , 5 9; Columbia, 1 <?; Bainbridge, 2 9; Spring Creek, 2 d"; Jackson- 

 ville, 5 <?, 1 9; Live Oak, 1 cT.
