Articerus tuinidus, Westw. 

 tumidus, Sharp 

 sharpi, Masters. 

 There appears to be no doubt, but that the same species 

 was described under the name of tuinidus by Westwood and 

 Sharp, and there is therefore no need for the name sharpi pro- 

 posed as a substitute for tumidus, Sharp. 



Articerus august icdII is, ^\ estw. 

 Recorded originally as from ants' nests. 



Articerus setipes, Westw. 

 Recorded originally as from ants' nests. 



Articerus asper, Blackb. 



Recorded as taken from flood debris. It is curious that this 

 is the only species that has been so recorded, as nests must 

 frequently be flooded out, and although I have seen thousands 

 of Pselaphidae in flood debris, I have never yet taken an 

 Articerus in it. 



The following species, although not so recorded, are certain 

 to occur in the nests of ants or termites. 



A. DeyroUei, Sharp. 



A. Duhoulayi, Waterh. 



A. falcatus, Ralfr. 



A. foveicollis, Raflfr. 



A. Kitigius, Sharp. 



A. nitidicoUis, RaflEr. 



A. Pascoeus. Sharp. 



A. Selj/si, Schfs. 



A. spinifer. Sharp. 



A. Westwoodi, Sharp. 



Articerus raffrayi, n.sp. (Figs. .32, 33.) 



3'. Reddish-castaneous, greater portion of each elytron some- 

 what paler than elsewhere. With short depressed setae, re- 

 sembling scales on head prothorax and parts of elytra, abdomen 

 with sparse erect setae, but fasciculate on each side of base.
