 that Walker may have discovered an error and relegated the 

 " species " to some other and more proper place. At all 

 events, it must be considered as non-existent and has to be 

 erased from our nomenclature. 



Pcecilocoris purpurascens, Westw. in Hope Cat. i. p. 14 

 (1837). 



Abundantly distinct from P. tnterruptus, Westw. {he. cit. 

 p. 14), and is not a synonym of that species as enumerated 

 in the * Cat. G^n. dcs Hemiptferes' of Lethierry and Severin 

 (p. 20).

Chcerocoris imganus. 

 C'nnex jyagmius, Fabr. Syst. Ent. p. 698 (1776). 



Attached to a specimen in the National Collection received 

 from the Wilson-Saunders collection, and localized New- 

 South Wales, is the following note : — " This species is fossorial 

 in soft sandstone. All this lot were taken in such a state, 

 and the remains of the pupa? were in the holes." 



CTictrocoris si mill's, sp. n. 



In markings above almost exactly similar to C. vari'egatus, 

 Dall., but the ground-colour is stramineous and not bright 

 red. Beneath stramineous ; head and sternum with sub- 

 marginal bhick lines; abdomen with a single marginal row 

 of angulated black spots. Legs stramineous, streaked with 

 black. 



The body is very much narrower and more elongate than 

 in C. variegatusj and the rostrum extends almost halfway 

 across the basal segment of the abdomen, while in Dallas's 

 species it about only reaches its base.

This is a most variable species, and it is more than probable 

 that some of those enumerated below as species are also
