﻿A NEW PROTURAN INSECT — GLANCE 311 



Tergite V (fig. 8G, e): In tbe anterior row, setae corresponding to 



I, 2, and 3 of tergite IV are absent; setae 4 are 12ju long; setae 5 are 

 14/1 long; setae 6 are 23/i long, posterior to setae 5; these are all in the 

 pleural region. The posterior row is slightly more anterior from the 

 margin, setae 1 being 9m distant; the setae are spaced about as on 

 tergite IV; primary setae mostly slightly longer than on tergite IV; 

 setae 1 are 23/i long; setae 2 are 31/z long; setae 3 are 35^ long, setae 4 

 are 31/x long; setae 5 are 15^ long; supplement aries same as on tergite 



II. Formula: Anterior row 3-3; posterior row 5-5+2-2 supple- 

 mentaries. 



The absence of the three pairs of setae in the anterior row differen- 

 tiates this species from all others of the genus The number of setae 

 in the posterior row agrees with that given for the genus by lonesco 

 (1935), and by Gisin (1945) for E. armatum Stach. See tergite VI 

 for comment on E. transitorium Berlese. 



Tergite VI : Anterior row same as tergite V. Posterior rov/ is one- 

 fourth distant from the margin; setae are spaced closer together than 

 on tergite V; setae 1 are 29^ apart, 29ja long; setae 2 are 31ju from 

 setae 1, and are 35^ long; setae 3 are 23^ from setae 2, and are 39/x 

 long; setae 4 are 34ju long; setae 5 are 12/1 long; supplementaries 23iU 

 long. Formula: Same as tergite V. 



The absence of the three pairs of setae in the anterior row differen- 

 tiates this from all other species of the genus. The number of setae in 

 the posterior row agrees with that given for the genus by lonesco 

 (1935) and by Gisin (1945) for E. armatum Stach. Berlese (1909, 

 pi. 8, fig. 83), figures tergites V and VI for E. transitorium Berlese, 

 but he has not shown all the pleural setae; however, on tergite VI, it 

 appears that anterior setae 3 are absent. In E. armatum delicatum 

 Gisin (1945), anterior setae 3 are absent. In the descriptions given 

 by Ewing (1940), for tergite VI he does not mention any of the 

 pleural setae; but for E. 'pallidum Ewing (1921), he notes that anterior 

 setae 3 are absent, and that anterior setae 2 and 3 are absent in E. 

 yosemitense Ewdng (1927). 



Tergite VII: Anterior row same as tergite V in only one female 

 specimen; in the other four specimens, setae 4 are absent. Posterior 

 row is placed a little more anteriorly than on tergite VI; setae 1 are 

 28/1 apart, 32/t long; setae 2 are 26^ from, setae 1, and are 37^ long; 

 setae 3 are 39^ long; setae 4 are 35ju long; setae 5 are 12^ long. Instead 

 of the usual supplementaries between setae 1 and 2, there are micro- 

 chaetae; supplementaries between setae 2 and 3 are 22jli long. For- 

 mula: Anterior row 2-2 or 3-3; posterior row 5-5 + 1-1 supplemen- 

 taries + 1-1 microchaetae. 



The number of setae in the anterior row differs from that given by 

 lonesco (1935) for the genus, and for E. armatum Stach bv Gisin
