The manifeft diffimilarity of thefe infers could have afforded no 

 reafonable ground for apprehending them to be the fame ; and this we 

 notice in juftification of thofe numerous writers above mentioned, 

 who have uniformly confidered them diftinct. The male infect having 

 been previoufly defcribed under the name of uliginofa, we have con- 

 ceived it right to retain that as the name of the fpecies, in preference 

 to marginatus, the term affigned to the female. The male has the eyes 

 large and brown, the thorax black ; abdomen pale yellowifh with a fmall 

 fpot of black on the firft and fecond fegment, the third immaculate, 

 the fourth with a fomewhat finuous band of black at the bafe, and 

 the remainder with a narrow black band ; that on the fourth fegment 

 being moll confiderable in fize. The underfide is dark with white 

 dots, and the legs yellow with duiky fpots. The eyes of the female 

 are large and reddim, thorax dufky, and gloffed with bronze, and the 

 abdomen black, with a fingle dorfal row of white triangular fpots : 

 the legs, as in the male, pale yellowiih, with the middle of the thigh 

 and (hank blackilh. 



The fmaller figures denote the natural fize, the larger, their appear- 

 ance when magnified.
