middle length. The first pair (fig. 4 e) are oblong, irregu- 

 larly shaped knobs, with hairs and very few long sette. 



Cerci (fig. 4/). — 'Hiey are rather long, slightly shorter 

 than the last pair of legs, about four and a half times longer 

 than deep, densely clothed with sette, many of which are pro- 

 truding in all directions and almost half as long as the depth 

 of the cerci, while the others are considerably shorter and 

 depressed. The terminal area is a little more than half as 

 long as the depth of the cerci, and looks downwards, the 

 surface above it (fig. ^g) with about ten sharply prominent 

 lines. The apical seta as long as or a little longer than the 

 area. 



Length. — 2'3 to 3"5 mm. 



Lo cality. — Calabria: Scilla, four specimens taken (by the 

 author) in June, 1893, in a copse about 1000 feet above 

 the level of the sea ; Aspromonte, in a forest about 4500 feet 

 above the level of the sea (the author). Furthermore, a good 

 number of specimens have been secured (by Mr. C. Borner) 

 either at Palmi in Calabria or, more probably, Catania in 

 Sicily. 



Remarks. — This species is rather allied to S. vulgaris, 

 n. sp., with which it certainly has been confounded by Prof. 

 Grassi. The differences between these two species will be 

 pointed out in the remarks to the last-named form. 



From all species with the first pair of legs rudimentary it is 

 separated by the clothing and shape of the cerci. and, S. 

 ex an a excepted, besides by the number of dorsal seta) on 

 he two distal joints of the posterior legs. 



It may be possible that some of the specimens collected by 

 Latzel, V. Attems, etc., and referred by them to S. nota- 

 cantha, in reality belonged to this species, and not to 

 y. vulgaris, n. sp. (see below), but on this topic nothing 

 can be said with the slightest degree of certainty. Further- 

 more, it is impossible to state with absolute certainty if the 

 animals upon which Grassi established his S. Isabelltx) 

 in reality belonged to our species with this name or to S. 

 vulgaris or to both combined, but the last-named circuni-
