EWING' S PROTURAN SPECIES — BONET AND TUXEN 281 



We have given figures of the mouth parts of both the holotype and 

 the specimen determined by Bonet. 



The female squama genitalis could not be drawn from the holotype 

 as the tip of the abdomen is bent downwards; so far as could be seen 

 it resembles that of vermiforme. 



Although this species has very many features in common with 

 vermiforme, we think that it is a different species because of the very 

 curious mandibles, the different sizes of the sensillae a' and especially 

 the proportion c 2:c 1, and the difference in the number of setae in 

 sIX-X.

Bonet redescribed pusillum in 1950 without figures. There are 

 only two slides present of this species, a female holotype in good 

 condition and three paratypes in poor condition. Data for holotype 

 and paratypes are, Orlando, Florida, in decaying leaves and twigs, 

 H. E. Ewing collector, May 26, 1922. 



On the fore tarsus (figs. 37-38), t 1 is without a thickened rim; a is 

 very small; the other sensillae are as they are in E. wheeleri. The 

 em podium is nearly as long as the claw; e:u = 15:17( = 0.9). The 

 t 1 is near a 3, not a 3'; d:p = 55:45(=1.2). The c' and t 3 were not 

 visible on the only foretarsus present on the four specimens. 



The female squama genitalis (fig. 39) is very different from that of 

 the other species; the processus stcrnales has pointed edges. 



The chaetotaxy as given by Bonet schcmaticalh 7 is as follows: 



IX-X XI XII 



8 8 9 



10 



■ "1" and "3" are missing. 



The most important points in the chaetotaxy are the presence of 

 all anterior setae on t V-VI and the fact that only four setae are miss- 

 ing on tVII. Having two anterior setae on sVIII and a central 

 posterior one, the species belongs to the wheeleri group.
