THK GKNEKA AND SPECIES OF SYMPHYLA. 77 



stance is the most probable. When Grassi (p. 596) states 

 that he has captured S. Isabellfe at Rovellasca (uearComo), 

 near Lecco, near Capua, and at Catania, it can be taken as 

 certain that he has had specimens of both species. I have 

 referred the name S. Isabellce to the species described 

 above, as it seems to be common at Catania. Mr. Borner, 

 who has captured many specimens of this species, but very 

 few of S. vulgaris, has labelled his animals "Catania, 

 Palmi," but 1 have not found it at Palmi, and suppose, 

 therefore, that Mr. Borner lias captured his specimens of 

 S. Isabella3 near Catania. 



6. Scolopendrella texana, n, sp. PL G, figs. 5 a — 5 e. 



Material. — Two adult specimens. 



Head. — Rather elongate, not quite one third longer than 

 broad. The central rod as in S. Isabella^, interrupted at 

 the middle, and having the anterior part and the frontal 

 branches strongly developed. 



Antenna3. — They contain nineteen to twenty-two joints. 

 The central whorl nearly as in S. Isabellge; a second whorl 

 begins below on the fifth or sixth joint, and a little before 

 the middle of the antennte it is complete on the outer surface 

 and above; the joints in nearly the distal half of the antenna3 

 (fig. 5 a) possess besides some seta? of one or two other whorls 

 on the lower outer part between the two complete whorls, so 

 that the lower half of the outer side has a rather considerable 

 number of short setas, and the distance between the central 

 and the secondai'y whorl is unusually long. 



Scuta. — The second scutum (fig. 5 &) with the hind margin 

 between the processes straight, and without striped band ; 

 the processes are large, slightly longer than broad, with 

 about four setae along each margin, and the usual distal seta 

 near the end. The distance between the processes is con- 

 siderably shorter than their length. The antero-lateral setfe 

 are rather short, not half as long as the processes, the lateral 

 seta? from the antero-lateral pair to the end of the processes
