complete row or with the two dorsal bristles somewhat separated from the lat- 

 erals ; fourth with marginal row well anterior to posterior margin and the 

 dorsal, central bristles still farther forward. 



Genital Segments. — Both dull orange or first somewhat brownish: first 

 with long, hairy vestiture posteriorly, marginal bristles absent; second polished, 

 vestiture about length of that on first, anal area small. Forceps darker than 

 second segment, with short upward flap-like prolongations ; prongs in profile 



truncated at ends and anterior corners pointed and slightly produced ; vestiture 

 short except on flap-like prolongations. The figure shows the details of the 

 genital segments (f. = forceps, a. c. = anterior clasper, p. c. = posterior clasper, 

 a. p. = accessory plate, g. s. 2 = second genital segment). Genitalia distinctive. 

 The holotype and the single paratype were both taken at Niagara 

 Falls, New York, on June 25, but the year and the collector are not 

 recorded.

Membracis humilis Fowler, variety aurora new var. 



This variety answers the description of M. humilis Fowler in every par- 

 ticular except that the pronotal markings are brilliant orange in color instead 

 of white. A series of thirty-nine specimens is shown in my collection, eight- 

 een males and eighteen females from Chosica, Peru, and three females from 

 Ecuador. Attempts have been made to change the color of these specimens by 

 various bleaching processes in the thought that the single specimen which 

 Fowler described might have been faded but the color appears permanent. 

 Since both sexes are represented and the series is a fairly long one and repre- 

 sents two localities, I believe this to be a constant color-variety of humilis. 



The females are slightly larger than the males and both sexes are uni- 

 formly black in body color with the markings bright orange. The eyes are
