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



Genus 3. Henicops*, Newp. 

 Caput latum, depressum, ocello magno utrinque uriico. Labium lamelliforme. 



1. Hen. maculata (Tab. XXXIII. fig. 37; Tab. XL. fig. 3.), capite cordato; subsegmento 



antennali subemarginato, antennis pubescentibus, labio complanato angulis rotundatis : 

 denticulis 6 acutis pauliim elongatis, mandibulis labioque laete aurantiacis, superficie 

 dorsali serie utrinque macularum aurantiacarum, ventrali pallide flava, pedibus cine- 

 rascentibus; pari postremo elongate. — Long. lin. 5. v. 6. 

 Hab. In Tasmania, {v. in Mus. D. Westwood.) 



This is one of the smallest known species of Lithobiidce; and it is interesting to 

 observe, that while it forms the type of a generic division, distinguished by the 

 organ of vision being only a single ocellus on each side of the head, it exactly 

 coincides with the true Lithobiidce in the form of the head, dorsal plates, legs, 

 and armature of the labium. In these respects it is exceedingly interesting, 

 as proving that the true characters of this family, although hitherto almost 

 entirely overlooked by naturalists, are as distinct in the species of the southern 

 hemisphere as in those of our own climate. This species is the first of the Li- 

 thobiidce hitherto received from Van Diemen's Land ; it was obligingly lent to 

 me by J. O. Westwood, Esq., who has also furnished me with references to some 

 of the published tracts on the Myi'iapoda. 



2. Hen. emarginata, ferruginea, pedibus flavescentibus, capite magno quadrato-ovato, lami- 



nis dentalibus distinetis transversis edentulis singula tamen emarginaturis 3 inconspi- 



cuis, scutis dorsalibus margine elevatis. — Long. ^ unc. 

 Lithobius emarginatus, Newp. Ann. ^ Mag. Nat. Hist. xiii. p. 96. 

 Hab. In Nov4 Zelandid. {v. in Mus. Brit.) 



This specimen is exceedingly interesting, as proving the existence of both 

 genera of Lithobiidce in New Zealand. It was brought to England in the collec- 

 tion of insects obtained by Captain Sir James C. Ross during his voyage to the 

 Antarctic regions, and- is ticketed in the collection as " found in the ground." 

 The specimen however is a young individual, but sufficiently matured to afford 

 a positive specific character in the emargination of the dental plates.
