308 Mr. R. Tcuipletoii's Memoir 



margin vvitli a double row of strong short spines of equal size ; 

 the antennae likewise are shorter. 



Habitat South of Europe. 



Length 0.8 inch., relative lengths 1.0, 1.2, 2.0. 



PI. XVI. fig. 12. Fourth scutellum of Cermatia coleoptrata. 



13. Margin of this scutellum exhibiting the spines. 



Sp. 5. Cermatia Caj^ensis. (PI. XVI. fig. 8 — 11.) 



Very common at the Cape of Good Hope, (my specimens were 

 hung up in a bottle and all their hind legs became detached, so 

 that I have merely sketched them, but I believe they are of the 

 accurate dimensions). Head smaller in proportion than in the 

 last species, pale yellow, the articulations marked with brown. 

 Body pale yellowish, witli a narrow yellow central fascia and a 

 brown dash between it and the side ; fourth scutellum sub-ovate, 

 with a row of minute marginal teeth or spines, every fifth or sixth 

 being longer and stronger than the others ; the spines on the 

 dorsum of the scutellum nearly obsolete. Legs robust and yel- 

 lowish, without dark annuli, or extremely faint on the coxae and 

 femora. 



Length 1.0 inch., relative lengths 1.0, 1.7, 1.4? 



PI. XVI. fig. 8. Cermatia Capensis a little magnified. 

 9. Last leg of the sixth scutellum. 



10. Fourth scutellum. 



11. Edge of the fourth scutellum exhibiting the spines. 

 PI. XVII. fig. 5. Magnified portions of the articulations of the joints of 



the antenna;, and the tip. 



n. Body short and of nearly equal breadth. 



Sp. 6, Cermatia longipes. 



Scutigera longipes, Lam. 



Sctitigcra araneoides, Guerin, Iconographie, 1, fig. 7. 



Savigny, Egypt, pi. 1, fig. 6. 



Clearly distinguished by the form of the body, shape of the 

 head, shortness of the anterior legs, and the exceeding length of 

 the posterior pair. 



Length 1.2 inch., relative lengths 1.0, 1.7, 3.0. 



Has not Guerin a joint too many at the base of the antennae, 

 Icon. 1, fig. 7(7 ? 



Note — the relative lengths are successively those of the body, 

 antennae, and last legs.
