anal plate is typical of uhleriana. Two of the females have the disk of 

 the pronotum darkened, much as in divisa, but the tegmina are of the 

 subtruncate uhleriana type and the form of the supra-anal plate is 

 equally distinctive. 



Ischnoptera uhleriana fulvescens Saussure and Zehntner. 



Seven males from Raleigh, taken in June and July, 1904, are referred 

 to this form. 7 



These specimens were taken under conditions similar to the Raleigh 

 individuals of true /. uhleriana. 

 Isohnoptera borealis Hrunner. 



While usually mistaken at first sight for uhleriana, this species is 

 readily separable by its usually smaller size and distinctly transverse 

 and apically rotundato-areuate supra-anal plate of the male. A 

 series of forty males of this species from Sulphur Springs were taken 

 on dates ranging from May 6 to June 12, 1904, and a single female 

 was collected at Lillington, Harnett County, on June 28, 1904, by 

 Brimley. The last-mentioned specimen was taken from under a log 

 in a wet place in woods. 



The general size is quite below the average of /. uhleriana, the male 

 extremes of the present series measuring as follows : 



Length of body 12.8 mm., 14 mm. 



Length of pronotum :; " 3 



Greatest width of pronotum 3.8 " 4.3 



Length of tegmen.. 14.5 " 18

The tegmina of the larger specimen are unusually long, no other 

 individual in the series approaching it at all closely in this respect. 



From early May to the middle of June this species and Ischnoptera 

 uhleriana could be found almost every night about the lights. 



Ischnoptera bolliana Saussure and Zehntner. 



The series before us consists of four males and two females taken 

 at Raleigh. May 30-31, and June 1-8, bred or attracted to light in 

 houses, and five males taken at Sulphur Springs between May S and 

 June 9, 1904. The coloration of the males is quite uniform, the disk 

 of the pronotum being dark with a medio-longitudinal paler bar 

 dividing it in two sections in all the specimens. The females are 

 similar in coloration to the type of the synonymous Kakerlac sehaefferi. 



This was one of the scarcer species at Sulphur Springs where all the
