near Algiers, March 19tli, 1803, one specimen ; Frais Vallon, 

 December 5th, 1892, one specimen; Gorge de la Chiffa, 

 Mai'ch 5th, 1893, one specimen. The specimens from the four 

 last-named places nre all small ; they have been collected by 

 Mr. F. Lesne, and belong to the Museum in Paris. 



Remarks. — The existence of the process on the femur 

 seems to be the only really sharp character separating this 

 species from S. immaculata, but this process, not met Avith 

 iu any other species known to me, is, in my opinion, an

 form possessing it as a valid species. 



Group II. 



3. Scutigerella unguiculata, n. sp. 1*1. 2, 

 figs. 2a-2A-. 



Material. — Nearly fifty specimens froui one locality. 



Head. — Seen from above very broad, with a shai'p lateral 

 angle at the base of the mandible ; the longest seta in front 

 of this angle about as long as the breadth of the basal 

 antennal joint. The central rod without visible frontal 

 branches; posteriorly it is scarcely visible, or generally 

 terminating at a rnther long distance from the hind margin 

 of the head, and a posterior area and oblique posterior rods 

 are not seen. 



Antennae. — The number of joints is generally from thirty 

 to thirty-four (in one specimen one antenna has twenty-one 

 joints, the other is broken.) The setae on the inner side of the 

 proximal joints not longer than those on the outer side. The 

 secondary whorl begins on the lower side about on the eighth 

 joint; on more than the distal half of the antenna this whorl 

 is well developed on the ventral half of the joints (fig. 2 a), 

 and besides one seta, sometimes two setas are found above 

 on the same joints; on one or two joints just behind the 

 terminal one a seta is often found below, behind the secondary
