THE GRNERA ANP SPECIES OF SYMPHYLA. 38 



Pocock as S. iin mac 11 lata ('Zool. Ergebn. einer Reise in 

 Niederl. Ost-Indien/ herausgeg. von Max Weber^ B. iii, 1894^ 

 p. 319), belong all to anotlier species, Scut, orientalis, n. 

 sp. Chile, Java, and Sumatra must therefore be omitted from 

 the countries in which S. immaculata has been captured. 



Eemarks. — The species is easily distinguished from all 

 following species, Avith exception of S. arm at a, by the 

 characters pointed out on p. 25 for Group I, by the shape 

 of the second dorsal scutum, and by the short setas and the 

 short terminal area on the cerci. 



2. Scutigerella arraata, n. sp. PL 2, figs. 1« — If. 



Material. — Several species, partly well preserved, from 

 various localities. 



Description. — The species is so closely allied to S. im- 

 maculata, and similar to small or middle-sized specimens of 

 this form, that a few remarks are sufficient. The head and the 

 antennae present no differences; the highest number of anten- 

 nal joints observed is thirty-one. The scuta as in the preceding 

 species, but the penultimate scutum has its two posterior 

 lobes equally rounded without incision. The last pair of legs 

 about as in S. immaculata; the claws of large specimens 

 (6g. 1 h) with the distal part of moderate length and slender, 

 the anterior claw rather considerably longer than the other. 

 The first pair of legs (fig. 1 c) have on the lower side of the 

 femur a very conspicuous vertical process, which is from one 

 and a half times to more than three times long-er than thick 

 (figs. 1 d and 1 e), subcylindrical, or distally somewhat conical 

 with the apex rounded; the claws of these legs (fig. 1/) 

 essentially as in smaller specimens of S. immaculata. 

 The cerci also as in that species, in the largest specimen 

 four and a half times longer than deep. 



Length. — The largest specimen measures 4"8 mm. 



Locality. — Algeria: Bona, five specimens among several 

 of S. immaculata (Dr. F. Meinert) ; Ravin de la Femme 

 Sauvage, end of December, 1892, one specimen ; La Bouzarea,
