than half as long again as the second, forming a slender 

 petiole, gradually widened towards the apex, where it is 

 nearly twice as broad as at the base; second tergite at the 

 apex at least four times as broad as the apex of the first. 

 Second transverse cubital nervure almost vertical. Tarsi 

 very slender, much longer than the tibiae.

This approaches the genus Trachypus in the petiolate form 

 of the first tergite ; but has not the sharply truncate apical 

 antennal joint characteristic of that genus. It is, however, 

 very distinct in the form of the petiole from any Oriental 

 Philanthus. The two species described by Bingharn from 

 Aden under Trachypus (Journ. Bombay Nat. Hist. Soc. xii. 

 p. 107, 1898) belong to Philanthus, and have not the petiolate 

 abdomen of this species. 



XL II I. — A TA«t of the Myriapoda of Ulster. 

 By Nevin H. Foster, F.L.S., M.K.l.A. 



The word Myriapoda as here used must be merely understood 

 as a convenient designation for an assemblage of many- 

 legged arthropods. Prof. Carpenter has shown* that the 

 time-honoured "Class Myriapoda" of P. A. Latreille ought 

 to disappear from systematic zoology, and that the Orders 

 embraced in this old Class are each worthy of Class rank.

 have been consulted : — Loudon's Mag. of Nat. Hist., 18oli,

It is remarkable that Thompson's 'Natural History of 

 Ireland ' contains no reference to the Myriapoda. The fourth 

 volume, which includes the Invertebrates, was published 

 in 1856, twenty years after Templeton's notes appeared in 

 Loudon's l Magazine.'
