364 Mr. Newport on the Class Myriapoda, Order Chilopoda. 



From the general appearance of this species, the large size of the head, and 

 the length and annulation of the legs, I am induced to place it at the head of 

 the genus as coming very near to the Cermatiidce. There is not a doubt of 

 its distinctness as a species, although M. Gervais * formerly imagined the con- 

 trary. It is exceedingly local, but exists in great profusion in some places. 

 There are more than thirty individuals, including males and females, in the 

 cabinet at the British Museum, all of which were captured at Wimbledon. 

 The annulations on the thighs and tibiae of the posterior five or six pairs of 

 legs sufficiently distinguish this from every other British species. The sexual 

 differences in the head of this species are very strongly marked. The head 

 of the female is much smaller and rounder than that of the male, and the 

 mandibles are less projecting. The species varies in the entire absence of 

 annulations on the thighs and tibiae, as well as in size, some specimens being 

 very much larger than others. This variety seems to be found in Ireland, as 

 there is a specimen which had been placed in the cabinet at the British Mu- 

 seum by the side of L.fojjicatus, ticketed in Leach's hand-writing, " Ireland," 

 and which specimen seems to have occasioned some mistake in the description 

 of L. forjicatus. 



2. Lith. rubriceps, capite magno subquadrato saturate rubro, ocellis parvis utrinque 14, labio 

 complanato profunde punctato; denticulis 14 parvis acutis nigris, corpore subolivaceo, 

 labio mandibulisque flavescentibus, pedum paribus posterioribus late nigro obscure 

 annulatis. — Long. 1 T ^ unc. 



Uab. In Hispania Australi. (v. in Mus. Brit.) 



The head is large, subquadrate, punctured, and narrowed anteriorly, and its lateral and pos- 

 terior borders are distinctly margined. The ocelli are small, black, and fourteen on each 

 side : the antennae are yellow and pubescent, with fifty-one joints : the labium is flat- 

 tened and deeply punctured, with its external angles produced, and the dental margin 

 nearly straight and armed with fourteen minute black teeth : the mandibles are large, 

 yellow, and tipped with black. The body is brown or subolivaceous ; and the legs yel- 

 lowish with the posterior pairs indistinctly annulated, with the tibial joints compressed, 

 densely ciliated, orange-yellow, and with the claw black. 



This is a magnificent species, closely allied to the last, and is the largest yet 

 discovered. It veiy much resembles the variety of L. variegatus from Ireland, 

 but is much larger.
