Ewing (1921b) to be synonymous with this species; however, a reex- 

 amination of the holotype of minimum showed it to be E. vermiforme 

 Ewing. 



The holotype, a female, was collected from decaying leaves at 

 Takoma Park, Maryland, by H. E. Ewing, April 3, 1921. 



The drawings were all made from the holotype except figures 25-26 

 and 28, which were made from a female collected in Fayette County, 

 Kentucky, by Ritcher and Sanderson on May 6, 1947, and determined 

 by Bonet. 



No foretarsus (see fig. 23) was found lying in a position suited for 

 drawing it from the interior side. The t 1 is remarkable in its pointed 

 shape, without the thickening along the margin as seen in the two 

 former species. In other respects the shape and size of the sensillae 

 are equal to those of vermiforme; however, b is stouter, and a and f 1 

 are much longer in E. pallidum. The t 1 is placed rather near a 3 

 and away from a 3'; d:p=75:80 (=0.95); e:u = 22:24(=0.9). 



The female squama genitalis (fig. 24) is of a peculiar shape, different 

 from that of the two former species. The processus sternales have no 

 sharp edges as in E. transitorium nor any beak-shaped rounding as in 

 wheeleri and vermiforme. 



The chaetotaxy is described by Bonet (1950, note that for denoting 

 the setae he uses other numbers than we do). Schematically it is 

 given as follows: 



The most remarkable facts are the missing anterior row of sVIII 

 (Bonet, 1950, built the pallidum group on this character), and the 

 missing six interior setae in the anterior row of t VII; only the lateral 

 one and the two "pleural" ones on each side are present. In the first 

 character pallidum resembles transitorium; in the second one it does 

 not. 



Figures 25-26 show the position of the ventral and tergal setae in 

 abd. vTII-XII from the specimen determined by Bonet. 



Figure 27 is of the holot} r pe and shows tlV; it is apparent that the 

 accessory setae are much longer than the principal ones. The lamina 

 anterior to the anterior apodeme is nearly invisible. 



Tarsus III (fig. 28) shows a very distinct spine. It is further re- 

 markable in its long empodium. The drawing is from the specimen 

 determined by Bonet.
